Waste Water Treatment Plants

Sewage Treatment Plants

We have got only one planet – EARTH, and we must protect it by all means. With increasing urbanization and industrialization, the pollution level in our surrounding has augmented manifolds, especially in India, where – due to several reasons – we have a high pollution rate as compared to many other nations in the world. Water pollution is one of them, and it is, perhaps, the most severe of all.

Pure water resources are less and – with increasing urbanization and industrialization - the consumption is increasing by leaps and bounds. The condition of Yamuna is not hidden from anyone. More than 55 per cent of New Delhi’s waste finds its way to Yamuna, and about 70 to 80 per cent of pollution in the river – which, according to Centre for Science and Environment, New Delhi, India, has more than doubled in last decade – is caused due to the industrial and residential sewage. In Mumbai, the condition of Mithi River has also deteriorated.

A sewage treatment plant is also known as a domestic wastewater treatment plant. Basically, what the process involves is cleaning up the sewage which is released from domestic and commercial sources. Normally this doesn't involve cleaning up waste which is released from particularly dirty sources, for example, heavily industrial companies or factory farms of nuclear reactor coolants. In modern sewage treatment plants there are three main stages: primary, secondary, and tertiary.
