Sewage Treatment Plants

ABS Group offers sewage treatment plants and its aims to acheive through physical ,chemical and biological clean water from black and mixed.This plant treated waste water local consumption from the city for the most part.

Sewage Treatment plant methods include:

A Primary Treatment:

It consists of decantantaction for removing particles smaller than a certain size suspended solids were unable to be removed in the pretreatment.This process is called Primary Treatment.

The sedimentation tanks provide sufficient capacity to establish quiescence in the wastewater, allowing solids with a higher specific gravity than water to settle and those with a lower specific gravity to float. Well-designed and well-operated primary treatment should remove 50 to 70% of the suspended solids and 25 to 40% of the BOD.


Free oil, grease and other floating material are removed by skimmers from the surface of the primary sedimentation tanks. Typical detention time in the primary sedimentation tanks is 1.5 to 2.5 hours. Chemical flocculants/polymers are frequently added to the primary sedimentation tanks to increase solids removal. Solids removed during primary treatment are dewatered and disposed of as part of the sludge treatment.

B Secondary treatment:


It consist of a biological process.Bacterias are placed in a large tanks.There they eat the organic matter,then the water passes to a second decantation.Secondary treatment typically removes 70 to 85% of the BOD entering with the primary effluent. dispersed by mechanical agitation.


The bacteria metabolize the organic carbon in the wastewater, producing carbon dioxide, nitrogen compounds and a biological sludge. Treated effluent from the aeration basins flows to secondary clarification. A portion of the sludge from the clarifier is recycled to the aeration basins or drying bed and the water from this is again treated under tertiary treatment.


C Tertiary Treatment:

Tertiary treatment (also known as “advanced wastewater treatment) is becoming more common as discharge permits increasingly call for the removal of specific contaminants not normally removed during conventional secondary treatment. In tertiary treatment is also used to: remove suspended solids to very low levels usually accomplished by filtration, remove refractory toxic organic compounds using activated carbon, or remove dissolved inorganic solids using ion exchange or membrane processing.

D Disinfection:


Chlorine - Clarified effluent from secondary treatment is usually disinfected with chlorine before being discharged into receiving waters. Chlorine gas is fed into the water to kill.Chlorination will kill more than 99 percent of the harmful bacteria in an effluent.

Ultraviolet - Ultraviolet irradiation is gaining market share as an alternative to chlorine disinfection. It obviates the risk and cost of storing and handling chlorine gas or other toxic chlorine containing chemicals.In addition, it leaves no chemical residue in the effluent, which is important if the water is to be reused or discharged to a river or estuary.


E Sludge Processing :

Sludge processing is complex and can consist of a variety of operations, including: sludge thickening, sludge stabilization by lime addition or digestion (either aerobic or anaerobic), sludge de-watering, and ultimately disposal by landfill, composting, land application.




Flushing and the sludge from the plant can be treated for composting,reuse as fertilizer in agriculture or other purpose.
