Effluent Characteristic From Sewage Treatment Plant

The purpose of treating domestic wastewater in treatment plant is to ensure that discharging of effluent meet the requirement by authorities. Without authorities forces, people will easily dumping and pollute our environment.

Basic concept in Sewage effluent are less toxic/no toxic to living entity and separation of organic solid. Reaching of recycle and reuse of effluent may the ultimate achievement to wastewater treatmment operators.

Normally, sewage effluent water in Malaysia contain less metal and heavy metal if the incoming sewage stands individually. For the old network sewarage piping system, the infiltratin run-off interrupting the standard final effluent (FE). Most township in this country were very old, sewerage networking system have been infected by natural wear and tear. Recently, sewer rehabilition is the one of focussed item in sewerage operation.

Other kind of discharge such as illegal chemical dumping, waste from chicken slaugter house, food processing factory will also increase SS, BOD and COD in discharge effluent. There are encumbrance to operators where the authorities forcing had change method of treating incoming sewage. This occurance had increase operation cost of treatment plant especially electricity, labour cost and sludge management.

What ever it is, BOD max of 20mg/l, COD max of 50mg/l, SS mas of 50mg/l, not detectable O&G and ammonia level which less than 10 mg/l must be achieved to save Malaysian's reserve water. We save our environment, that means we execute our responsibility. God Bless Us.
