When conservation of water is done, for water to be re-used again or be channeled to rivers its always advisable to treat it. The aim of doing is to make sure the water is very safe for re-use and also does not lead to the endangering of the marine life. The sewage treatment process involves so many stages before its totally pure.
Some of these challenges can be overcome but others are out of control. For one to come up with pure drinking water heavy machinery has be applied. This means also a technician to carry out the whole process is a requirement. And since this is very costly for factories and individuals who may want to recycle back the water for other uses, it becomes a big challenge.
After the solids have been fully separated the waste water is then put in massive settlement tanks. At the tanks bottom is a big scrapper which is mainly used to scrape the floor in order to bring the sludge to the center of the tank to allow it to be pumped for further treatment. In this stage the waste water is treated primarily, thus the primary treatment stage.
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.
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.
