Wastewater treatment

Wastewater treatment, also called sewage treatment, the removal of impurities from wastewater, or sewage, before it reaches aquifers or natural bodies of water such as rivers, lakes, estuaries, and oceans. Since pure water is not found in nature (i.e., outside chemical laboratories), any distinction between clean water and polluted water depends on the type and concentration of impurities found in the water as well as on its intended use. In broad terms, water is said to be polluted when it contains enough impurities to make it unfit for a particular use, such as drinking, swimming, or fishing. Although water quality is affected by natural conditions, the word pollution usually implies human activity as the source of contamination.

Sewage Treatment Plant

Sewage treatment plants (STPs) are the main pollution source of micropollutants, including pharmaceuticals and personal care products (PPCPs). Understanding the biotreatment processes of domestic and hospital wastewaters is important for the optimization of micropollutant degradation at the discharge source in order to decrease their concentrations and associated biological effects. It is known that a large group of compounds comprising aliphatic, aromatic, and halogenated molecules are co-metabolized during nitrification by the enzyme ammonia monooxygenase (AMO).

Effluent Treatment Plant

Effluent is generated in many manufacturing industries like textile, pharmaceuticals and chemicals, tanneries etc. Contaminated water cannot be released without treatment as it contains toxic and non-toxic chemicals. Releasing it may cause contamination of the existing pure water and will affect the environment. As a result ETP’s are installed in most manufacturing industries.

The Effluent treatment plants (ETP) are used for the removal of high amounts of organic compounds, debris, dirt, grit, pollution, toxic, non-toxic materials and polymers etc. from industrial effluent. The ETP plants use evaporation and drying methods and other auxiliary techniques such as centrifuging, filtration , incineration for chemical processing and effluent treatment.

Grey Water Treatment

Membrane Bio Reactor (MBR), Ceramic Filtration Technology

Greywater can be defined as any domestic wastewater produced, excluding sewage. The main difference between greywater and sewage (or blackwater) is the organic loading. Sewage has a much larger organic loading compared to greywater.Some people also categorise kitchen wastewater as blackwater because it has quite a high organic loading relative to other sources of wastewater such as bath water.

People are now waking up to the benefits of greywater re-use, and the term “Wastewater” is in many respects a misnomer. Maybe a more appropriate term for this water would be “Used Water”.

TSE Polishing Plants

We provide solutions for packaged and modular Treated Sewage Polishing Plant(TSE systems) from 50M3/Day up to 5000 M3/Day as Standards. We polish the treated sewage water with the help of ultra-filtration membrane (0.01 micron[µ] to 0.1 micron[µ]) and reverse osmosis membrane to achieve the high-quality product water equivalent to drinking quality, which can be used for cooling tower, cement batching plant, high quality irrigation water etc.,
