Waste management – re-use, recycling and disposal of solid waste from manufacturing, commerce and domestic sources.
The objective of the treatment is to produce both a clean wastestream (or treated effluent) suitable for discharge or reuse back into the environment, and a solid waste or sludge also suitable for proper disposal or reuse.
In older plants and plants receiving more variable loads, trickling filter beds are used where the settled sewage liquor is spread onto the surface of a deep bed made up of coke (carbonised coal), limestone chips or specially fabricated plastic media.
The purpose of disinfection in the treatment of wastewater is to substantially reduce the number of living organisms in the water to be discharged back into the environment.
Wastewater overflows the effluent weirs of the clarifiers and is transported to the secondary treatment process.
As the strength of the incoming wastewater increases, the oxygen demand of the activated sludge organisms increases, requiring more dissolved oxygen to be supplied by the aeration equipment and conversely, when the incoming organic concentration decreases, the oxygen demand of the organisms decreases.
Wastewater overflows the effluent weirs and is transported to the chlorine contact tanks for disinfection.
