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.
Since the aim of treating sewage is to save water by recycling it back. During the process some the chemicals and hard metals are hard to be separated from the water. This poses a health risk to human beings and also to the plants when the water is used for irrigation purposes. These metals can expose human beings to lifetime diseases like cancer when water is used for drinking purpose.
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.
The last final stage is the tertiary treatment. At this stage water is further treated beyond secondary stage, which makes the water to be 99% pure. The technology involved in this stage is very costly and requires professional with knowledge to completely understand the whole process.
However, disinfecting the waste water is another way of treating sewage waste, the process involves the use of chlorine and since chlorine is very expensive most people may end up ignoring the exercise. This again poses dangers to the environment in the long run.
To remove water particles, water is left to run on a bed of sand to ensure further filtering. After the filtration process has been carried out, the water at this level is always safe to be freely channeled to the river. This water can be re-used in homesteads, for irrigation of plants and also in making the rivers healthy. The quality of water channeled to these rivers is normally controlled by the environment management authority agencies which ensure only clean treated water is piped to these water catchment areas. Water treatment procedure comes along with a lot of advantages in that it ensures that the water we use in irrigating our crops and also re-used in our homes is safe for all our domestic activities we carry out in our homes.
