                        MUNICIPAL WASTEWATER TREATMENT
                                  PROCEDURES
This appendix can be used to estimate and evaluate energy use in wastewater
treatment (WWT) unit processes.

Part I consists of tables, supporting data, and formulas for estimating energy
use in both acquisition and operating WWT unit processes.

Part II consists of procedures for surveying energy use in operating plants.
                                   A-l

-------
                                    PART  I
                         ENERGY ESTIMATION PROCEDURE
The attached procedures can be used by planning and operating personnel to
estimate the energy requirements of construction and operating WWT unit
processes.  Acquisition energy includes both the embodied energies of the raw
materials and the energy consumed  in construction.  Operating energy consists
of energy consumed in plant operation but does not include the energies
embodied in consumables such as chlorine, oxygen, and maintenance materials.
The estimating procedures are based on typical plants but may be varied for
significant differences in design  parameters.


1.0    SCOPE

       1.   This manual describes  the method for estimating acquisition and
            operating energy requirements of wastewater treatment plants in
            the 0.5 to 100.0 MGD flow range.

       2.   Acquisition energies for comparison among treatment alternatives
            may be estimated from  tables or by the technique described herein
            for units not covered  in this manual.

     -  3.   Operating energies for comparison among treatment alternatives or
      . .     with energy survey results may be estimated by use of tables for •
            processes covered by this manual with optional adjustment for flow
       '  : ;  rates arid other design parameters.  Illustrative block diagrams
            may be found in Exhibit I4-1A and I4-48A.

       4.   Acquisition and operating energies should not be added together
            for comparison among treatment alternatives as they have different
            levels of precision which may bias the results.

       5.   Energies are not accurate beyond two significant figures.  Users
            are .advised to round off all totals to only two significant
            figures prior to use.   (The calculated values are left in the
            tables to permit the user to follow the methodology.)


2.0    APPLICABILITY

       1.   Unit processes having  both acquisition and operating energy tables
            are listed in Exhibit  I1-1A.

       2.   Unit processes with operating energy tables only are listed in
            Exhibit I1-1B.
                                    A-2

-------
3.0    METHOD FOR ESTIMATING ACQUISITION ENERGIES

       1.   Determine the wastewater flow rate in million gallons per day
            CMGD) and unit processes to the included in the process train for
            the proposed plant.

       2    For the units listed in Exhibit I1-1A interpolate (see Section 5)
            the energy values for the appropriate flow rate.  Reference energy
            values may be found in.Exhibit 12-1.

       3.   For those units not covered in this manual and for which you have
            a breakdown of the cost of materials, you may calculate acquisi-
            tion energies using Exhibit 13-1 as your worksheet   Energy values
            in Exhibit 13-1 are shown per 1967 dollars.  To convert current
            component costs to a 1967 base  multiply costs in column one by
            the following adjustment factor:

                 F - (Base 1967 Index Value)
                     (Current Index Value)

            Exhibit I3-1A presents monthly published indices recommended for
            different cost components.  Exhibit I3-1B presents base 1967
            values of indices for a number of components.

       4.   After unit process energies have be calculated, add the energy
            values of the process train together.  This will give you the es-
           . floated acquisition energy.


4.0    METHOD FOR ESTIMATING OPERATING ENERGIES

       1.   Determine the design wastewater flow rate in MGD and the process
            train for the proposed or existing plant.

       2.   For units in the process train that are covered in this manual
            (see Exhibit 11-1)  interpolate (see page A-108 of Appendix A) the
            energy values for the appropriate flow rate   Use Exhibits 14-1
  . ..."  .     through I4r35 for the reference energy values by interpolating
            values for the typical plants.

       3a.   If the design parameters are unknown and/or the energy usage of
            the full range of generally accepted designs for a unit process is
            desired  interpolate the maximum and minimum values to the appro-
            priate flow rate to estimate the operating energy range.

       or

       3b.   If the design parameters are known and you require a more
            precise estimate  use the equation listed below each table to
            adjust the estimated typical operating energy for your
            specific case.

       4.   After calculating energy requirements for the unit processes, add
            them together to get the estimated plant operating energy
                                   A-3

-------
5.0    INTERPOLATION METHOD

       1.   Use the wastewater  flow  rate  in  MGD  for the proposed  plant.

       2.   Use the worksheet in  Exhibit  15-1 to interpolate  the  flow rate.

       3.   Determine which  flow  rates  (from the appropriate  tables)  are
            closest to your  plant.   The higher value  is X2, the lower value
            is XI.

       4.   The following  section describes  the  use of interpolation  equa-
            tions.  As an  alternative, the worksheet  in Exhibit 15-1  may  be
            followed for each interpolation.  Energies may be interpolated
            using this formula:

                             Y  ซ  mX  + b

             where:          m  ป  Y2  - Yl
                                  X2  - XI

                             b  ซ  Y2  - mX2 or Yl  - mXl

                             Y  is interpolated energy for your plant

                             X  ซ  flow of  your plant

                             Y2 = Energy  from Table at the flow rate
                                 • that is greater than your plant flow

                             X2 = Flow rate  that is greater than  your
                                  plant flow.

                             Yl = Energy  from Table at the flow rate
                                  that is less than your  plant flow.

                             XI = Flow that  is less than  your plant
                                .  .flow.

                                   PART II
                           ENERGY SURVEY PROCEDURE
The attached procedures are designed to evaluate systematically energy use in
wastewater treatment (WWT) plants by surveying all electric motors and heating
devices associated with the WWT process.  Energy.Survey Procedure A assesses
the energy use of all electric motors  (i.e. the energy use of pumps, compres-
sors, comminutors, etc.), while Procedure B assesses all heating devices
(electric resistance heaters, oil or gas fired furnaces and heaters, or steam
supplied by an out-of-plant source).  All other energy users should be
addressed on a case by case basis and will be summarized on this form, with
the results from the two energy survey procedures.  Notes to plant personnel
on use of results of energy surveys follow the procedures.

-------
                         PROCEDURE A-ELECTRIC MOTORS
1.0  SCOPE
       1.   This procedure describes the method and requirements  for
            performing an energy survey on all electric motors  associated with
            a municipal wastewater treatment process.

       2.   This procedure encompasses all electric motors at the facility
            which have a direct effect on the operation of the  process  train.
            This procedure does not include facility electric loads such as
            building lighting or HVAC not directly associated with the
            wastewater treatment process.

       3.   Data collected from this survey may be used to measure the  net
            energy requirements of all electric motors, along with the       !
            efficiency of all motors.
2.0  APPLICABILITY
       1.   Net energy requirements of electric motors  at  all  municipal
            wastewater treatment plants can be reviewed using  this  procedure.
            This may include packaged wastewater  treatment units  and  low  flow
       ........ .processes of less, than .0.5 million gallons  per day (MGD)  influent,
            to full scale facilities over  100 MGD influent.

       2.   This procedure can be used during both design  and  operational
            phases to evaluate energy usage.  In  addition,  this procedure
            allows for power  (kilowatt) input to  be compared to power usage
            for each motor.  This provides operational  data designed  to
            evaluate the efficiency of all motors in the plant.
3.0  PERSONNEL

       1.   This survey may be  conducted by the plant  engineer,  plant
            superintendant, or  a designated assistant.

4.0  EQUIPMENT

       1.   The equipment  needed to perform this  survey  is  as  follows:

            •    Voltmeter
            •    Clamp on  Amperage Meter  (ampmeter)
            •    Wattmeter  (either portable or hard  wired  into the  individual
                 motor circuit)
                                    A-6

-------
5.0  ENERGY SURVEY METHODOLOGY

       1    Using a separate form (Exhibit II1-1) for each major plant
            process  record the number  function  and process system of each
            motor associated with the wastewater treatment process in column 1
            of the Survey Record Chart.   A unique identification should be en-
            tered for each motor surveyed.  For example:  #2 Sludge Pump.
            Primary.

       2.   From the manufacturer's name plate attached to the motor, record
            motor horsepower  voltage  and frequency in columns 2. 3  and 4,
            respectively.

       3.   The motor must be operating for five minutes prior to the
            performance of any testing.   Therefore  motors (pumps,  etc.) in a
            standby status should be scheduled for operation, and started
            prior to this survey   This may require separate surveys of opera-
            ting and standby motors.   All readings will be taken at the motor
            controller. -..   '     ;  ,    -        ,•'..  ...-.  .

       4; .  Using the voltmeter, read the voltage (E) across each phase of the
            motor and record the average voltage  in volts  on the Survey
            Record Chart in column 5.

       5.   Using the ampmeter, read the current (I) and record the
            amperage  in amps  on the Survey Record Chart in.column 6.

    .  .6..   Using the wattmeter, read the power, twice, at five minute
            intervals  and record"the average-.power  in kilowatts (KWV on the
            Survey Record Chart in column 7.

       7    Disconnect all portable meters arid return the system to normal
            operation.

       8    Estimate the motor's duty cycle by computing the fraction of time
            the motor is in operation at normal capacity.  This may be
            performed by using any of the following techniques:

            1)   Visual observation of motor run time in a given period (i.e .
                 minutes per hour, hours per shift or per day)

            2)   Examination of motor operating log

            3)   Examination of elapsed running time meter, if available

            4)   Precise operating knowledge of each system.

            This fraction is entered in Column 8 of the Survey Record Chart.
            For example- if the motor is in operation for 30 minutes each
            hour, the duty cycle is 50% and the operating fraction is 0.5.
                                   A 7

-------
 9.   Convert the power requirements to energy usage per year by
      multiplying the power in column  7 by the duty cycle  fraction  in
      column 8 and multiplying the result by 6760 hours.   Enter the
      energy usage per year, in Kilowatt-hours  (KW-hr) , in column 9.
                                                                •
10.   Calculate the power factor of each motor and record  it in column
      10 of the Survey Record Chart.   The following subsections describe
      the calculation:

      1}   For three-phase motors, solve for Kilo volt- Amps
           (Kva) using the following formula:

           KVA - (1.732) (E) (I)
                       1000

           where   E is the voltage from column  5
           and     I is the current from column  6

           Using this value solve for  the power  factor:

                       power factor ป  KW
•    •                              -
           where   KW is power  from  column  7
           and     KVA is value previously  calculated.

           Enter the power factor  in column 10  of  the
           Survey Record Chart

      2)   For single-phase motors,  solve for KVA  using
           the following formula:

           KVA =  (E) (I)
                  1000

           where   E is the voltage  from  column  5
           and     I is the current  from  column  6.

           Using this value solve  for  the power  factor:

                       power  factor  =  KW
                                       KVA

           where   KW is the  power from column 7
           and     KVA is  the value  previously calculated.

           Enter the power factor  in column 10 of  the
           Survey Record Chart.
                              A-8

-------
11.   If the power factor is less than 0.80 the electrical operator or
      plant engineer should comment, in column 11, concerning the low
      energy efficiency of the motor.  (Normally operates at low
      efficiency, etc.)

12.   Add all values in column 9 to evaluate the section yearly energy
      use of all motors associated with that WWT process.  Record this
      value, in KW-hr, in the box marked "subtotal."

13.   Add all "subtotal" values to evaluate the total overall yearly
      energy usage of all motors.  Record this value, in KW-Hr, in the
      box marked "total yearly energy usage" under electric motors on
      the summary page of the Energy Survey.

14.   Convert this value to British thermal units  (Btu's) by multiplying
      by 3413.  Record this value, in Btu's, in the box marked total
      yearly electric motor energy (Btu)  on the summary page of the
      Energy Survey.

                     PROCEDURE B-HEATERS AND INCINERATORS
1.0    SCOPE
       1.   This procedure describes the method and requirements for
            performing an energy survey on all heaters and incinerators
            associated with a municipal wastewater treatment process.

       2.   This procedure encompasses all heaters and incinerators at the
            facility which in whole or part have a direct effect on the
            operation of the process train.  This procedure does not  include
            facility heating loads such as building heat.

       3.   Data collected from this survey may be used to measure the net
            energy requirements of all process heating applications.
2.0    APPLICABILITY

       1.   Net energy requirements of heaters and  incinerators can be
            reviewed by using this procedure.  This may include package
            wastewater treatment units and  low flow processes of  less than 0.5
            million gallons per day  (MGD),  influent, and to scale facilities
            bearing capacities of over 100  MGD,  influent.

       2.   This procedure can be used during both  design and operational
            phases to evaluate energy usage.

3 V0;  "' PERSONNEL  ' " •             •.••..'               .    . .  :  •••

       1.   This survey may be conducted  by the  plant engineer, plant
            superintendant, or a designated assistant.

4.0    EQUIPMENT

       1.   For electric resistance heaters or incinerators a Wattmeter
            (either portable or hard wired  into  the individual heater or
            incinerator circuit) is required.

       2.   For natural gas or steam heaters or  incinerators no additional
            equipment, beyond station instrumentation, is required.

5.0    SURVEY METHODOLOGY

       1.   Using a separate form  (Exhibit  II1-1)  for each plant  process sec-
            tion, record the number, function, and  process system of each
            heater or incinerator associated with  the wastewater  treatment
            process in column 1 of the Survey Record Chart.  A unique identi-
            fication should be entered for  each  item surveyed.

       2.   Record the type of heater or  incinerator in column 2. For
            example:  steam heaters, electric resistance heaters, multiple
            hearth incinerators, etc.
                                    A-10

-------
3.   The heater or incinerator must be operating for 1 hour at normal
     load prior to the performance of any testing.

4.   All electrical readings should be taken at the control panel.

5.   Only one value per heater or incinerator should be entered  in
     either columns 3, 4, 5, or 6 as follows:

     1)   For electrical resistance heaters, read the power  (in
          kilowatts) and record the value on the Survey Record Chart  in
          column 3.

     2)   For natural gas or oil heaters or incinerators, record the
          normal monthly gas or oil process stream consumption in
          columns 4 or 5, respectively.

     3)   For steam heaters, determine the steam flow through the
          heater and record the flow rate, in pounds mass/hour
          (Ibm/hr), in column 6.

6.   Estimate the heater or incinerator duty cycle by computing  the
     fraction of time the heater or incinerator is placed in   .......  ..
     operation.  This fraction is entered in column 7 of the Survey
     Record Chart.  If in continual use, enter 1.0.  This method may
     not be accurate if the incinerator is on standby or started up
     and shut down many times.  You should check results of this
     calculation against your fuel bills for these cases.

7.   Convert the recorded values in columns 3 through 6 to energy usage
•~": ' per'year as follows:  '   "•" "'"'••'    ' '      '   •'•• ' '•'•''   '   '   •  •

     1)   For electric heaters, multiply the power in column 3 by the
          duty cycle fraction in column 7 and multiply the result by
          8760 hours.  This result is then multiplied by 3413 to
          calculate the number of Btu/year.  Enter the resulting
          energy/year, in Btu/yr, in column 8 of the chart.

     2)   For natural gas, multiply the volume/ in column 4, by  1000
          Btu/cubic feet  (Btu/ft ), and multiply the result by 12 to
          convert to a yearly energy usage.  Enter the result in column
          8 of the chart.

     3)   For oil, multiply the volume, in column 5, by 112,000
          Btu/gal, and multiply the result by 12 to convert to a yearly
          energy usage.  Enter the result in column 8 of the chart.

-------
      4)    For steam (not accounted for in sections  (1),  (2) or  (3)'
           convert the value in column 6 to Btu by use of a steam table
           (i.e. for a given pressure, read the value of specific en-
           thalpy for saturated steam (Btu/lbm); multiply this value by
           the flow rate and calculate the Btu/hr.)  Multiply this
           result by 8760 hours to calculate the Btu/year.  Enter this
           value in column 8 of the chart.

 8.   Comment on any unique plant systems, i.e., steam from a furnace
      used to heat a different process stream, etc.

 9.   Add all values in column 8 to evaluate the total yearly energy use
      of all heaters and incinerators associated with the WWT process.
      Record this value, in Btu, in the box marked total yearly heating
      energy (Btu) on the summary page of the Survey Report.

10.   Add all subtotals for each process stream and enter the total, in
      Btu, in the box marked "Total Yearly Energy Usage" under "Heaters
      and Incinerators" on the summary page of the Survey Report.
                             A-12

                           NOTES TO PLANT ENGINEERS

                                USE OF RESULTS
This section is a general discussion of using results of this survey.  Each
wastewater treatment plant is unique.  This manual cannot cover all cases.
Therefore, the results of the survey must be interpreted by appropriate plant
personnel.  We recommend examination of two areas:

       o    Validation of the energy survey against energy bills.

            The energy survey does not include lighting and HVAC (Heating,
            Ventilating and Air Conditioning) demands; properly-conducted
            energy survey results should be about 75 to 95 percent of
            energy bills.  Unusual and identified energy sources (e.g., use
            of digester gas) or demands may be an exception.  If there is
            an inexplicable or undocumented difference between, energy
            survey results and energy bills  then the cause should be   •   .
            investigated.

       o    Comparison of the validated energy survey against the operating
            energy estimate (Part I).

            The operating energy estimate from Part I represents typical
            operating experience adjusted for major design differences   If
        " •'  the validated energy survey is significantly different from the
      ..  ..  : .operating., energy estimate  and the causes of this difference are
            not clearly defined, considerable benefit may result from inves-
            tigation of reasons and of investment in energy reduction (if your
            result is high) or dissemination of your information about your
            operating practices (if your result is low )

Energy Estimation Equation:

    E  •' = 4000 X FL X 4.5/SC X SQ/2100 X Dist/20
Where:
  FL - Plant Flow is MGD
  SC '- Solids Concentration,. Percent
  SQ - Sludge Quantity, Ib/Mg
  Dist - Distance, Miles     .    .
*  This operating energy is too site specific for use of a table.
Use the equation to estimate the operating energy for each
situation.
