This project calls for the secondary treatment of :
25,000 m3/day of Municipal Domestic Waste Water Stream
25,000 m3/day of Combined Industrial Waste Water Stream
Municipal and industrial streams are detrained separately in two dumping areas ( North and South Pits) via sewage tankers.
All sewage trucks are screened before they are allowed to dump their loads in order to avoid hi-toxic industrial waste entering the plant.
Industrial waste goes by pre-treatment insertion and from there into the equalization tank. From the Equalization tank, it goes to primary clarifiers and into aeration tanks.
Municipal waste goes through its own pre-treatment insertion and into the equalization tank and from there it mixes with the industrial stream right after the primary clarifiers and the mixed stream goes to the aeration tanks.
Both streams are mixed and combined in the aeration tanks and from there the mixed stream goes to the secondary clarifiers. For advanced secondary treatment, the mixed streams also flow through anoxic and anaerobic tanks for nutrient and nitrogen removal.
The resultant stream is of an advanced secondary treated grade
