1. Are Sewage Water Treatment Plants Really Important? Sewage treatment refers to the process of removing contaminants from waste water. The polluted water has to undergo chemical, physical and biological procedure to remove the contaminants and produce the clean and environment friendly water. The sludge that is produced as the by-product of the treatment has to be processed further before it may be made suitable to for the land application. There are many kinds of treatment plants and they differ on the ground of treatment optimization and design. Now let’s take a look at the different treatment variants: Anaerobic Sewage Treatment The sewage is partially decomposed by the anaerobic bacteria in the tank without air. It causes the organic matter to reduce to methane, carbon dioxide etc. This treatment is used to treat organic waste and it provides huge capacity and significantly reduces the input material to a large extent.

2. Then There Is Aerobic Treatment of Sewage In this procedure the pollutants are digested by the aerobic bacteria. In these plants the air is supplied to the bio-zone. In the process, the pollutant and odors by providing complete oxidation and the absorption of the organic pollutant and the matter into carbon dioxide, nitrogen and water. After the treatment the effluent is free of the pollutant and is discharge free. There are three stages of sewage water treatment as under: In primary treatment the sewage flows through the huge tanks that are known as primary sedimentation tanks. The sludge settles down in these tanks while the oil & grease keeps on floating on the surface and is removed. The sludge is collected towards the hopper at the base of the tank which is then pumped for the sludge treatment. In secondary treatment the biological waste from humans, soap, food waste and detergent are degraded to a large extent. The municipal plants treat the sewage that is collected through the aerobic methods. The effluent that has been treated earlier contains the dissolved biological matter. It is then converted into clean water with the use of the bacterial and waterborne aerobic micro-organisms that absorb the pollutants. The effluent is now clean enough to be discharged into the water.

3. In tertiary treatment the effluent is treated to the best quality before being finally discharged in-to environment. This treatment has to be of very high standards so that the effluent that comes out if fit to be discharged in environment. In The End With right treatment optimization and design, the sewage plant can effectively clean the polluted water.
