ARTICLE II – PURPOSE; SPECIFICATIONS
2.1
Purpose; Scope of Work. The purpose of this Invitation for Bid (this “IFB”) is to secure a
qualified Vendor to provide neat Polymer (the “Materials” or “Polymer) for use at the City’s Waste Water
Treatment Plant (the “WWTP”) during fiscal year 2017-2018. Materials purchased under this IFB are primarily
intended to be used to thicken primary and waste secondary sludge and to dewater anaerobically digested sludge
at the WWTP. This City will only consider Bids for neat Polymer. The selected Vendor shall provide
transportation, delivery of the Materials to the WWTP and removal of empty containers (the “Services”). The
resulting Contract is intended to be an indefinite quantity and indefinite delivery contract for the Materials based
on the City’s needs. The City does not guarantee any minimum or maximum amount of purchases will be
requested by the City under this IFB.
2.2
Quality of Materials. Polymer shall be supplied in tote containers. Materials not meeting the
Specifications as outlined in this IFB, if known at the time of delivery will rejected, at the sole expense of the
Bidder and without any additional cost to the City.
2.3
Delivery of Materials. The quantity ordered per shipment will be determined by the City at the
time the order is placed. Normal deliveries of Materials should be made within 72 hours from the placement of

Friday. The City will not accept deliveries on Saturdays, Sunday or Holidays, or during off hours. If requested
Vendor shall develop a delivery schedule to be followed during the term of the Contract. If the operational
requirements of the WWTP dictate, the City may elect to change Vendor’s delivery schedule. Should Vendor
be unable to comply with the delivery schedule, fail to keep the WWTP in a sufficient supply of the Materials,
or not be able to supply the WWTP with an unexpected or emergency delivery within 24 hours (due to lapse in
communication, manufacturing, transportation, or any other cause), then the City reserves the right, in its sole
discretion to obtain materials from any source without waiving or voiding any of the terms and conditions of the
Contract.
B.
Fuel Surcharges. Bidders should carefully consider any and all fuel costs to
manufacture, transport and deliver the Materials and return totes or storage containers after use. These costs are
considered an integral part of the Bid price. This City will not accept additional fuel surcharges during the term
of the Contract. Vendor will be required to honor its Bid price for the term of the Contract, without price
modification or additional fuel surcharges.
C.
Shipping, Receiving and Unloading. The Vendor shall supply all equipment necessary
to ensure the safe delivery of the Materials.

EXHIBIT A
TO
INVITATION FOR BIDS FY 17-18 - Polymer
See following pages.
DLT:dlt 2662343.3.1 5/5/2017
Polymer Performance Testing and Evaluation
Per Article III, Section 3.1, (I) of the IFB, Polymer Performance Testing (“Performance Testing”) is required
prior to submitting a bid, and must be completed by no later than Friday, May 26, 2017 for the Bidder’s polymer
bid to be considered. Prospective polymer bidders should contact [email protected] , or call (623) 4788742 no later than Monday, May 22, 2017 to schedule a Performance Testing date. Jar testing is not required,
but is an opportunity made available to prospective Bidders prior to the performance testing, and is on a first
come first serve basis.
I.
JAR TESTING
Jar testing is not Performance Testing. Performance Testing is discussed in Section B, below. Jar
testing allows each prospective Bidder the opportunity to determine which of their polymer product(s)
(Materials) to use in the Performance Testing. Prior to the date of the actual Performance Testing, each
prospective Bidder will be afforded the opportunity to jar tests at the City of Tolleson Wastewater Treatment
Plant (TWWTP). The City will provide the Bidder with samples of feed sludge from the various thickening and
dewatering units, and a space in the laboratory to perform the jar tests. Any equipment, materials and apparatus
necessary to perform jar testing shall be furnished by the Bidder, and brought to the TWWTP site on the day of
jar testing. Jar tests are not required and is up to the discretion of each Bidder as to whether or not to perform
such testing.
To take advantage of this opportunity, bidders should contact [email protected] , or call (623)
478-8742 no later than Monday, May 22, 2017 to schedule a Jar Testing date. If scheduling Jar Testing, it is
also incumbent upon the prospective Bidder to schedule a Performance Testing date, and to do so on or before
the stated deadline for Polymer Performance Testing.
As the operation of each thickening and dewatering unit is based on the needs of the treatment process,
and may vary from day to day; no guarantee is made or implied that the conditions encountered on the day of jar
testing, including but not limited to sludge quality, quantity or concentration will be duplicated on the date of the
actual performance testing.
II.
POLYMER PERFORMANCE TESTING
A. General Information
Bidders shall furnish at their sole cost and expense, a sufficient supply of product [e.g. either, in buckets
having a nominal size of five gallons or in tote bin(s)] to conduct the Polymer Performance Testing. A
minimum of fifteen (15) gallons of polymer is suggested to conduct the testing at the three (3) unit locations onsite at the TWWTP. Each Bidder is required and responsible for disposing of any leftover polymer after the
Testing is completed.
The City will not be responsible for lost, stolen, returned, misdirected or missing shipments of the
Bidder’s product to the WWTP. Each Bidder is solely responsible for the preservation of their product integrity
and the security for any and all of their products brought to or delivered to the TWWTP.
All aspects of the Polymer Performance Testing, except as may be noted in the Polymer Performance
Testing Procedures section of Exhibit A will be conducted by TWWTP personnel. During the performance
testing of the Bidder’s Polymer, TWWTP personnel will operate and control all solids handling equipment at
each thickening and dewatering location, and will make any and all adjustments such setting belt tension, as
applicable. These adjustments include but are not limited to belt speed/drum speed, water dilution, sludge feed
rates, polymer feed rates, recording performance data, and collecting and controlling all samples.
Bidders are welcome and encouraged, but not required. to be present and observe the Performance
DLT:dlt 2662343.3.1 5/5/2017
A-5
Testing of their polymer(s). During the performance testing, Bidders will be allowed to suggest adjustments of
dilution water and polymer feed settings. However, the plant operator, prior to making any adjustments
requested or suggested by the Bidder, will first make a visual observation to ascertain whether such adjustment
is conducive to maintaining the TWWTP’s customary and characteristic operation for each unit. Achieving any
adjustment(s) suggested by the Bidder, and the ability to achieve any adjustment is up to the sole discretion of
TWWTP personnel at the time of testing, and whose decision is final.
The City is not obligated to provide dilution water beyond the capabilities that presently exists at any of
thickening/dewatering units (Gravity Belt Thickener, Belt Filter Press or Rotating Drum Thickeners) or is
otherwise deemed unsustainable, impractical or undesirable as judged solely by TWWTP personnel at the time
Performance Testing is conducted. Technical adjustments at each thickening/dewatering unit, and the accuracy
thereof, such as obtaining and operating any of the units at a sustained, and specific percent solution of polymer
are not part of the TWWTP’s customary operation, and therefore, is not guaranteed. Adjustments may be
limited to unquantified or non-empirical adjustments, such as “a little more” or “a little less” water or polymer,
as applicable. For units having a numeric display of the dilution rate, the accuracy of the reading is not
guaranteed, nor is achieving or sustaining the operation of the unit at a specific percent dilution.
Performance Testing will be limited to a maximum of 60 minutes, at each thickening/dewatering
location, barring any malfunctions or failures of TWWTP equipment or devices deemed essential by TWWTP
personnel to conducting the Performance Testing.
Bidders will be allowed to bring field testing device(s) for their personal use in analyzing percent
moisture and/or Total Suspended Solids (TSS) during the Performance Testing. The use of any data obtained
by the Bidder from their device(s) is strictly limited to serve as an aid to the Bidder in making recommendations
or suggestions for optimizing feed polymer and water dilutions during the performance testing. The Bidder’s
use of said data for any other purpose is strictly prohibited, and such data is summarily considered null and void
by the City. Only the percent solids and TSS results from samples collected by TWWTP personnel, under a
chain of custody authorized and completed by TWWTP personnel, and which is analyzed by the TWWTP
laboratory (#AZ0418), or by another laboratory certified by the Arizona Department of Health Services (ADHS)
as may appointed by the City, shall be utilized by the City in determining the official result of each Performance
Test.
Based on sludge production data for calendar year 2016 (January 1, 2016 through December 31, 2016)
an overall, estimated, total daily average of 11.0 dry tons of sludge was processed through the thickening and
dewatering equipment at TWWTP. This amount was computed by adding the estimated, daily average sludge
production from each thickening and dewatering location. During that period an estimated, average 1.8 dry tons
of sludge per day was processed through the Gravity Belt Thickener (BT), and an estimated, average 5.4 dry
tons of sludge per day was processed through the Rotary Drum Thickeners (RDTs), and an estimated, average
3.8 dry tons of sludge per day was processed through the Belt Filter Presses (BFPs). These sludge production
estimates, including the total estimated, average daily sludge production of 11.0 dry tons were computed from
daily operating averages of the thickening and dewatering equipment, and are shown in Tables A1.1, A1.2, and
A1.3 (below, in this section).
The Polymer Performance Testing seeks to determine individual polymer performance at each unit
location by quantifying the amount of sludge feed (in dry tons), and the amount of polymer required (in lbs) to
thicken/dewater the sludge. The capture rate is also measured and used in the calculation that determines cost of
polymer per ton of dry solids for each unit location. The cake, percent solids is also measured, and is an
important aspect to the operation at each unit location. Cake solids are not factored into the formula for
determining the overall polymer cost per ton of dry solids.
During the Polymer Performance Testing the WWTP operator will seek to stabilize the operation of the
thickening/dewatering equipment using the Bidder’s polymer. Stabilization of the unit’s operation is considered
as having been achieved when the unit operates for several minutes (a minimum of five (5) minutes, but longer
DLT:dlt 2662343.3.1 5/5/2017
A-6
if deemed appropriate by the TWWTP Operator) at the normalized operation, without need for further
adjustments. The normalized operation is one that achieves the customary, characteristic and sustainable
operation of a thickening/dewatering unit (i.e. the Gravity Belt Thickener, the Belt Filter Press, or the Rotating
Drum Thickener), and is the sole judgment of the City (TWWTP Operator) at the time Polymer Performance
Testing is conducted. The term “customary” refers to the manner, in which the City (TWWTP personnel)
normally operate, or is accustomed to operating each thickening/dewatering unit, and is irrespective of the
operation and objectives of thickening/dewatering units at other facilities. The term “characteristic” refers to the
normal operating performance of a thickening/dewatering unit at the TWWTP, and is based on the visual
observations of the TWWTP operator, alone. The term “sustainable” refers to the TWWTP operator’s
judgement that the stabilized operation of a thickening/dewatering unit has been achieved, and is reasonably
expected to continue to operate in the normal and acceptable manner, at the given settings, without further
adjustment being needed. Once the operation is stabilized, the WWTP operator will collect the samples (sludge
feed, filtrate, and cake) from the unit, and perform the timed polymer drawdown (recorded in ml/min), record
sludge feed (in gpm), and any other pertinent data.
Based on sludge production data from January 1, 2016 through December 31, 2016, an overall average
11.0 dry tons per day of sludge was processed through all thickening and dewatering equipment at WWTP. This
amount is derived as a proportion of the amount of sludge processed through the thickening and dewatering
processes, combined. That figure is based on an average of 1.8 tons of sludge per day was processed through
the Gravity Belt Thickener (BT), and an average of 5.4 tons of sludge per day was processed through the
Rotary Drum Thickeners (RDT), and an average 3.8 tons of sludge per day was processed through the Belt Filter
Press (BP). These are the figures used by the City in the calculation (the formula) for determining the estimated,
overall polymer cost. The formula is further explained in Section C, below.

OVERALL POLYMER COST DETERMINATION AND EVALUATION OF BIDS
At the TWWTP, sludge is conditioned with polymer for thickening at the Rotary Drum Thickener (RDTs),
the Gravity Belt Thickener (BT), followed by anaerobic digestion, then conditioned again with polymer and finally
dewatered at the Belt Filter Presses (BFPs). The estimated amount of sludge produced at each of these unit
locations is shown in Tables A1.1, A1.2 and A1.3, of this Exhibit A. These amounts are based on the average
daily runtime (in hours), the average percent solids of the sludge feed, and average daily feed rate (in gpm) for
each thickening/dewatering unit location over the previous calendar year (January 1, 2016 through December 31,
2016). During that time period the TWWTP processed with polymer an 11.0 dry tons of sludge per day, estimated,
annualized, total daily average.
The City deems it expedient to compare the Polymer Bids based on the overall cost of each Bidder’s
Polymer to process one ton of the 11.0 dry tons of solids processed on a daily basis. This method requires the
actual cost of each Bidder’s polymer (per dry ton solids) be determined at each thickening/dewatering location, and
for those costs to be proportioned to the amount of sludge processed overall. The following formula provides this
proportioning of the cost to the overall amount of sludge processed, and yields the overall aggregate cost of a
Bidder’s polymer to process one ton of dry solids (Overall Polymer Cost):
Overall Polymer
Cost (per dry ton)
=
(RDT$ x 5.4 tons) + (BT$ x 1.8 tons) + (BP$ x 3.8 tons)
11.0 tons
Where:
DLT:dlt 2662343.3.1 5/5/2017
A10
RDT$ - The actual cost of the Bidder’s polymer (in dollars), per ton of dry solids, as
obtained from the 2017 performance testing at the Rotary Drum Thickener (RDT)
BT$ - The actual cost of the Bidder’s polymer (in dollars), per ton of dry solids, as
obtained from the 2017 performance testing at the Gravity Belt Thickener (B.T.)
BP$ - The actual cost of the Bidder’s polymer (in dollars), per ton of dry solids, as
obtained from the 2017 performance testing at the Belt Filter Press (BFP)
The average sludge production for the 2016 calendar year (January 1, 2016 through
December 31, 2016) was:
5.4 (Average dry tons of sludge per day produced at the Rotary Drum Thickener)
1.8 (Average dry tons of sludge per day produced at the Belt Thickener)
3.8 (Average dry tons of sludge per day produced at the Belt Filter Press)
11.0 (Average, total dry tons of sludge per day treated with polymer)
The Overall Polymer Cost formula provides a single figure (in dollars/dry ton) for each responsive Bidder.
The actual polymer cost (in dollars/dry ton) of a Bidder’s polymer as determined from the performance testing at
each thickening/dewatering location, is entered into the numerator of the formula, as applicable. The function is
then carried out to provide the Overall Polymer Cost (in dollars/dry ton), for each responsive Bidder.
These costs (the actual polymer cost, and the overall polymer cost) are not determinable until after the bid
opening and the Total Delivered Price (TDP) for each polymer is known. Therefore, after the bid opening the City
will determine the actual, and overall polymer costs (in dollars/dry ton) of each responsive Bidder’s polymer,
whose determination are final.
The successful Bidder will be determined on the basis of the overall, lowest responsive and responsible bid
and other pertinent considerations. The City of Tolleson reserves the right to reject any or all Bids, to waive any
informalities or irregularities in the Bids received, and to award the Bid which in the City’s sole judgment best
serves the interests of the City. Only one Vendor (Bidder) will be selected to supply polymer for the thickening
and dewatering operations at the City of Tolleson WWTP for FY 2017~18. This includes all polymers necessary
to operate the rotary drum thickeners (RDTs), the Gravity Belt Thickener (BT), and the Belt Filter Presses (BFPs).
