With the rise in factories and industries, there is a greater amount of chemicals, waste, effluents flowing into the water resources thus contaminating the natural resources and contributing to the cause of diseases to man kind. Hence, there is a need for pollution control related machinery and equipments. Few industries have already made a mark in this field and thus helping us save the water resources.

The need of the hour is to treat water, protect natural water resources from getting depleted, recycling waste water or their treatment. This effluent treatment machinery aims at removing the contaminants from house hold sewage. It involves the treatment of water which is polluted with biological, physical and chemical contaminants. It treats the water in such a way that it not only prevents the contamination of the natural resources, saves the living creatures which feed on them but also make these contaminated water suitable for use. We don't have to suffer due to water scarcity thanks to the sewage treatment machinery.

Various treatments that these machineries can be used for are:

-Raw water treatment
...
... -Sewage water treatment
-Wastewater treatment
-Effluent treatment etc.

These are made suitable for discharge into the natural resources so that they don't jeoparides the natural habitat and the living creatures. If not these chemical, biological and physical contaminants will not only pollute the water resources but also contribute to the growth of unwanted algae and other poisonous plants. Living creatures which feed on them are susceptible. In turn, you can prevent a lot of unwanted happenings by treating waste water and sewage in the right way!

Sewage systems capable of handling storm water are known as combined systems or combined sewers. Such systems are usually avoided since they complicate and thereby reduce the efficiency of sewage treatment plants owing to their seasonality. The whole process involves physical, chemical, and biological processes to remove physical, chemical and biological contaminants.

The main purpose is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds.

However, there are some draw backs to these sewage treatment plants. The Sewage treatment plants fail to remove artificial sweeteners completely from waste water. These pollutants contaminate waters downstream and may still be present in our drinking water. That's the only down side to it.
