Upon recommendation of Navid Mehram, Chief Operating Officer - Wastewater Operating Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. 2303191, "Clarifloc DPA-7-0335" with Polydyne, Inc., at a cost not to exceed $7,380,000.00 for a duration of three (3) years plus two (2) 1-year renewal options; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
The GLWA Water Resource Recovery Facility (WRRF) produces approximately 295 wet tons of sludge daily as a byproduct of wastewater treatment process. This sludge typically contains 90-95% water, and to prepare it for further processing in our solids processing facilities, we need to reduce its water content to a range of 75-80%. This is accomplished through the utilization of belt filter press units, which effectively compress the sludge and extract the excess water, achieving the desired concentration. Prior to entering the belt filter press, we employ a polymer coagulant, specifically Clarifloc DPA-7-0335, a proprietary blend supplied by Polydyne. These polymers, organic substances, enhance the efficiency of coagulation with solids, resulting in the formation of larger and more stable floc. The addition of polymers in the dewatering process significantly reduces solids in the recycle stream and increases the percentage of solids in the dewatered sludge cake. This procurement requires the vendor to adhere to all local, state, and feder...
