Waste Water Treatment

Effluent is generally considered as water pollution, flowing out of a factory, farm, commercial establishment, or a household into water bodies such as a river, lake, streams, ponds or a sewer system. Nowadays effluent has gained a wider coverage as it includes   almost every waste that pour into our water and air. Liquid factory waste, smoke, and raw sewage can all be called effluents. Industrial effluents contain various materials, depending on the type of industry. Some effluents contain oil and grease, some contain toxic materials too, and effluents from food and beverage factories contain degradable organic pollutants. Since industrial waste water contains a diversity of impurities and therefore specific treatment technology called ETP is required. Effluent Treatment Plants are another form of   waste water treatment plant which are designed and manufactured specially for treating water that contains effluents and working towards making the water effluent-free. Th...

With increasing environmental concerns and legislation, installation of sewage treatment  plant (STP) and e ffluent treatment plant  (ETP) has become a mandatory compliance for industrial sectors to continually improve the discharge standards and to lower the environmental hazards; Kelvin Water Technologies Pvt Ltd offers sustainable solutions for treatment of all types of waste water with its advanced STPs and ETPs. Kelvin company provides complete waste water solutions for sewage treatment, effluent treatment and common effluent treatment. The ETP and STP plant work at different levels and involves various processes such as physical, chemical, biological and membrane processes based on advanced technologies. With more than hundred successfully operating installations of STP and ETP, our designs provide highly economic STP/ETP installation & operation, minimal waste generation, lowest footprint area and waste water treatment to the specified standards by legislatio...

Activated sludge is a process for treating sewage and industrial wastewater using air and a biological flock composed of bacteria and protozoa. This process is one part of Sewage water treatment Plant (STP) . The process involves introduction of air or oxygen into a mixture of primarily treated sewage or industrial wastewater combined with organisms to develop a biological flock which reduces the organic content of the sewage. A  Conventional Activated Sludge (CAS)  system commonly includes an aeration tank, which is used for biological degradation, and a secondary clarifies (sedimentation tank), where the sludge is separated from the treated wastewater .     This is the most common and oldest bio-treatment process used to treat municipal and industrial wastewater. Typically, wastewater after primary treatment i.e. after removal of suspended impurities, is treated in an activated sludge process based on biological treatment system comprisi...

The treatment process varies as per the type of effluent generated. Wastewater enters the treatment plant and goes through several processes before the effluent is released to the environment. Industrialeffluent treatment process includes the following stages: *  Preliminary treatment  is aimed at removing the large sized contaminants from waste water. It includes following activities: a. Screening:  This is the first operation carried out in wastewater treatment plants . A screen is a device with uniform openings and its purpose is to remove large floating solids. b. Sedimentation:  It is a physical method to have the solid contaminants get settled at bottom of any container using gravity so as to remove suspended solids from water. c. Grit Chamber:  The wastewater that passes through the grit chamber removes the dense inorganic solids such as gravel, metal   fragments and sand which have made their way into the sewers. Removal of gri...
