LAGOONS INLET

Inlet works including flow distribution and oil retention facilities, floating oil skimmer and oil holding sump.

AERATED LAGOONS

Four aerated lagoons providing approximately five days retention equipped with floating surface aerators.

PRELIMINARY TREATMENT

Preliminary Treatment : Screening Grit removal� �The purpose of these units is to produce an approximately constant flow to the treatment units free from gross and abrasive material.

PRIMARY SEDIMENTATION TANKS

The wastewater enters the tanks through the central inlet pipe and leaves over the peripheral weir. The settled solids are removed from the base of the tanks as primary sludge, while grease, oil and floating solids are retained on the surface by baffles and removed with the scum.

AERATION TANKS

Activated sludge process and comprises three aeration tanks fitted with five fixed mechanical surface aerators per tank

SECONDARY SETTLEMENT TANKS

Secondary treatment comprises Aeration tanks, eight Final settling tanks, and three return activated sludge pumps.

PRESSURE FILTERS

Tertiary Filtration is necessary to effect sufficient suspended solids removal, and reduction of non-biodegradable organic compounds to produce a high quality effluent suitable for irrigation purposes.

CHLORINE PLANT

A chlorination system is installed to produce a residual concentration of this chemical.

SLUDGE DEWATERING BELT PRESS

The Sludge is first thickened in tanks where the supernatant liquors return to the upstream of the screens. The thickened sludge are passed to filter belt presses where additional moisture is removed by mechanical means after the addition of polyelectrolyte.

DEWATERED SLUDGE CONVEYOR

The sludge cake is transferred by a series of belt conveyors to storage bins prior to disposal at the Sanitary Landfill.
