The process mainly contained three stages namely: Primary treatment, Secondary Treatment, and Tertiary Treatment. In the primary treatment, large objects, solids are screened using filters and removed. In the secondary treatment, more solid particles and organic matter present in the wastewater is removed using biological treatment. In the tertiary process, disinfection or chlorination takes place to make the effluent good enough to be released or reused.

Plenty of people probably use toilets multiple times in a day. A large amount of precious water is flushed down the drain turning it into waste. According to a statistic provided by Conserve H2O, a Water Providers Consortium, 1.6 litres of water is wasted per flush. Depending on the toilet cistern parts, toilets can use even more water.

A home flush system uses up to 12 litres of water per minute. Plumbing experts say that in commercial buildings, 45 litres of water is utilized per day per employee. The huge amount of water wasted can be treated for drinking.

Wastewater which contains a large amount of toxic chemical is treated well before releasing it into the environment to prevent harm to humans, animals and plants. The anaerobic process is one of the most effective and efficient biological processes for the treatment of wastewater where micro-organisms are used to degrade the organic matter. The process is undertaken in the absence of oxygen.

Approximately 38,300 million litres of sewage is generated daily in the major cities of India as per a recent report from the UN water activity information system. The number is staggering, isn’t it? If you are thinking from where does such a huge amount of wastewater generate? There are majorly two sources – Industrial waste and Domestic sewage. As both the population of India and Industrial Landscapes is increasing at a phenomenal speed, wastewater volume has also seen an alarming rise.
