Primary Treatment
In primary treatment, sewage is stored in a basin where solids (sludge) can settle to the bottom and oil and lighter substances can rise to the top. These layers are then removed and then the remaining liquid can be sent to secondary treatment. Sewage sludge is treated in a separate process called sludge digestion.
Secondary Treatment
Secondary treatment removes dissolved and suspended biological matter, often using microorganisms in a controlled environment. Most secondary treatment systems use aerobic bacteria, which consume the organic components of the sewage (sugar, fat, and so on). Some systems use fixed film systems, where the bacteria grow on filters, and the water passes through them. Suspended growth systems use “activated” sludge, where decomposing bacteria are mixed directly into the sewage. Because oxygen is critical to bacterial growth, the sewage is often mixed with air to facilitate decomposition.
The treatment process coagulation flocculation and filtration through chlorine dosing.
The treatment process done through aeration system then filtration through chlorine dosing.
Klaro one SBR sewer water treatment plant, is a fully biological waste water treatment system from GRAF, operates according to the SBR process.
This treatment consist of one tank separated into two raw waste and treated water, air diffusers, horse pipes, pipes , one blower and controller.
