The project consisted of the design and upgrade of the existing treatment plant to cater for future flows from the egg processing facility. The contract consisted of the installation of a new concrete pump sump complete with duty standby pumps and level controls. The flow is the sent through a rotary drum screen mounted on a bespoke High Level GMS platform.

Screened effluent gravity feeds  to a concrete balance tank with duty/standby submersible mixers.

The effluent is then pumped via two Drywell submersibles through a pipe flocculator to allow pH correction and the addition of flocculant and coagulant. A dual polymer make-up system was supplied and installed complete with dosing and ancillary equipment.

A Hydro DAF designed for 20m³ / hour was installed and the sludge conveyed to the existing Sludge Holding tank via a PC pump.

Treated effluent from the DAF gravitates to the Anoxic Tank with submersible mixer which overflows to the aeration tank via gravity and is aerated via two duty/standby 37 kW Aerzen Blowers with acoustic enclosures. The blowers are controlled to give an optimum DO based on a probe mounted within the aeration tank.

The mixed liquor overflows to the Membrane Bioreactor for clarification by Kubota flat sheet submerged membranes. The treated water is then discharged to a local water course.

DAF Sludge and Waste Activated Sludge dewatered  by Screw Press mounted at high level.

The plant is controlled via a new MCC installed within an existing building with remote dial in and control possible via VNC.
