What are the various steps to waste water treatment?

Wastewater from pharmaceuticals, industrial units and even home should be treated to get rid of pollutants. Wastewater mainly undergoes primary and secondary treatment before the water may be used for other purposes. TGWasteWater treatment process should be established within the facility itself and is required at the source of the water than the end of the pipe. The first step to wastewater treatment is choosing a simple treatment process which is easy and reduces the operational costs and maintenance charges. There has to be a strategy to treat the wastewater from various sources.

Determine grey water and black water

Wastewater can be classified as grey water and black water. The former does not contain human waste and mainly comes from washing dishes and doing the laundry. Black water has human waste and it cannot be used without processing. Wastewater has to undergo different stages of processing and only then the contaminants can be reduced.

The various stages of water treatment

TGwastewater treatment may be divided into three stages:

·             There is a pre-treatment process whereby larger substances or larger wastes that may clog the pumps are removed. If this is not done, there will be delay in primary treatment.

·             After the pretreatment process, heavy solids are made to settle at the bottom whereas the lighter waste materials like grease, oil are made to float. Heavy solids that settle down at different layers are eliminated from water.

·             The secondary stage or step to wastewater treatment is a specialized stage whereby large amounts of microbial unicellular life are removed. Here there is the use of various filter beds to facilitate oxidation of water followed by purification.

·             Tertiary water treatment comes next. In this stage, water is treated to an extent that it may be used at places with delicate ecosystem. The clean water can be further recycled into natural resource or may be supplied once again.

TG wastewater treatment is essential. It is done to remove the impurities and decaying matter from water.
