Job Description
Poultry Slaughter/Processing Plant
Plant Description
The wastewater treatment plant (WWTP), is a small mechanical, chemical, & biological plant designed to treat the liquid waste streams generated in the poultry processing plant such that the resultant water stream may be discharged to the natural environmental according to the requirements of the Certificate of Approval (EC of A) for the plant. The WWTP is a tertiary treatment plant with capability to reduce total suspended solids (TSS), five day carbonaceous biological oxygen demand (BOD5), ammonia nitrogen (NH3N) and total phosphorous (TP).
The primary treatment portion of the wastewater treatment system consists of:
1.basket type course screens installed within each floor drain throughout the processing area to prevent large solids from entering the wastewater collection system,
2.one wastewater collection sump, associated pumps and level switches to deliver wastewater to,
3.one rotary screen with 20 micron openings to remove the larger solids that have entered the wastewater system and which discharges to,
4.one equalization tank and a feed pump which, moderates the flow rate to the DAF, and,
5.one Dissolved Air Floatation (DAF) unit, which removes the majority of remaining TSS along with much of the TP and discharges to the rotating biological contactor (RBC) equalization tank.
The secondary treatment portion receives wastewater from both the DAF and untreated domestic sewage from the laundry and washrooms. It consists of an equalization storage tanks, fine bubble diffusers, level switches and associated pumps that discharge to one RBC. The primary function of the RBC is BOD5 removal; and nitrification. pH adjustment to facilitate chemical precipitation in down stream processes is executed in the RBC's third and fourth stage.
The tertiary treatment portion of the system consists of:
1. A baffled clarifier to settle solids, an effluent chamber with associated pumps and level switches, which provide for sedimentation of TSS,
2. Sand filtration, which provides TSS polishing,
3. Cartridge filtration for further TSS polishing, and,
4. U.V disinfection to limit discharge of pathogens to the natural environment.
