Water is life and its beyond any reasonable doubt that water is one of the most crucial component in our lives, without water life can not be easy. So any efforts to treat the sewage water and re-cycling it back for re-use is very important. This is where sewage treatment process comes in.
The first stage in sewage treatment is the screening, here floating and suspended objects or solid are removed. These objects may include broken bottles, sanitary items, plastics, rags, nappies and even towels. This process ensures that the incoming waste water BOD is reduced to 20-30% and 50-60% that of suspended solids.
Some of these companies may opt to channel the waters either untreated or halfway treated. This is because the exercise is very expensive hence this poses a lot of dangers to human life and also to the marine life. Though the environmental management agencies have encouraged the move to treat these wastes, determining who is conducting the exercise properly is difficult for them. This is a big challenge to the environment.
After the primary stage is the secondary stage water treatment procedure. At this stage big regular tanks are used. The importance of this stage is to ensure that any sludge that might have escaped during the primary stage has been removed.
Another benefit of the exercise is that, it helps in keeping the environment clean. Before sewage treatment systems were introduced, the cesspools and septic tanks were used to discharge waste; this posed a lot environmental risks especially to the areas where the waste water was being discharged. This increased the rate of pollution on the environment thus posing a lot of healthy risks to human life and the ecosystem as whole. The move has contributed a lot in preserving the environment naturally.
During the treatment process, the odor can be a nuisance to the environment. This is because its very difficult to control the bad smell emanating from the sewage. The situation worsens when certain chemicals are used to treat the waste. This leads to increased pollution of the environment.
The aim of this procedure is to remove any additional nitrogen and phosphorous that might have not been removed during the process. And since the procedure is too expensive for home users to carry out, disinfection with chlorine is done. Through at some level chorine is not highly advised to be used since chlorine is known to lower ultraviolet radiation effectiveness and again its costly when treating factory water.
Also those who are in a position to use chlorine may end up using small or high amount of it. This may result by them wanting to disinfect the water more thinking that it will make the water more pure. High levels of chlorine are harmful to both human being and also plants. Instructions on how to disinfect the water should be followed to the later to avoid exposure of such effects. The environmental agencies should also create awareness of these issues and educate people on cheap and efficient ways to treat sewage waste. This will help reduce the effects people pose to their bodies and even to the ecosystem at large.
