In order to free the water consumed for irrigation or drinking and even household purposes from all sorts of harmful contaminants, Sewage Treatment Plant plays a quite crucial phenomenon. The containments present in the waste water should be significantly decreased by getting rid of bacteria, suspended solids and all other organic wastes as well as chemicals that make the water polluted so that can be reused again.
Sewage Treatments denotes domestic wastewater management and seeks removal of pollutants from household sewage that consists of domestic and runoff. On an average, environmental engineers are accountable for designing and erecting facilities where wastewater is to be treated. There are various ways and means as physical, chemical besides biological approaches through which wastewater can be treated and is sent back to the environment so that it can be reused.

Sewage Treatment Plant that is usually set up for treating sewage embraces three stages-i.e. entire procedure has to undergo primary, secondary &tertiary stage of treatment. In the very first step solids are mined out from the waste water and it is through usage of home cultivated water borne micro-organisms dissolved matter is transformed into solid masses. Residues remained are there after nullified and then after thrown away or re-used. Thus, the water gets disinfected either physically or chemically with the support of lagoons or microfiltration.
In the end, the water that has been treated is now discharged into either river, stream, wetland or either it can be reused for irrigating farms.
The treatment plant developed for cleaning sewage works to eradicate suspended solids in addition to bio chemical oxygen demanding waste also known as BOD as this helps to reduce fish kill, as of diminishing oxygen levels that can leave adverse effects on marine life. Diverse forms of treatment are as follows.
1. Primary Treatment
In this phase substances that can be removed effortlessly from waste water are eradicated as oil /fat/ racks and even trash..
2. Secondary Treatment
This procedure cuts down the biological toxins that are present inside the sewage. At this juncture micro-organism are assisted to eliminate the undesirable elements present in the sewage.
3. Tertiary Treatment
This step emphasises on the betterment of the quality of the water, prior to sending back to the environment for usage for all purposes. This can be accomplished either by treating it by artificial filters or by natural filters like marshlands and even lagoons. With the help of treatment excess phosphorus and nitrogen can be removed.
For total removal of microrganism, a treatment plants have to often take a treatment of chlorination prior to release of treated waste water. Ultimately this chlorine is being eliminated from water after being chemically treated by sulphur di oxide reaction; and this helps in making water safe for the life that is dependent on it.
At last, this treated water is released in river, ponds lakes or even sea whatever is the closest destination. There are lots of services providers who provide solutions to fix drainage problems in a very cost effective manner.
