Wastewater treatment is defined as a process that removes contaminants from water generated through various activities for environmental sustainability. Within this frame, municipal wastewater equipment has been found to play a critical part, especially in the area of industrial wastewater treatment. WWI equipment means the type of machinery and apparatuses used in the processes of treating wastewater in municipal and industrial suspensions. They have been developed to help remove different kinds of waste from the wastewater and to eliminate the pollutants and impurities in the water to give the treated water that is relatively clean and that can be discharged back to the environment or for reuse.
The most important role of equipment used to collect municipal wastewater is in the areas of screening and filtering. It includes processes by which materials such as sticks, plastics, and other solid waste are removed from the waste water stream. These screens and filters are placed at the inlet areas to catch these particles and prevent them from passing to the subsequent treatment units where they may be damaged or significantly inhibit the working efficiency of the system.
Chemical processing is also another important operational process in the treatment of industrial and municipal wastewater and the industrial wastewater equipment used is very important in the chemical treatment phase. A number of these chemicals like coagulant, flocculant, and disinfectant are incorporated into the wastewater and are used to flocculate and discharge the contaminants of the wastewater. Pre-mixed and dosing equipment like mixers, reactors and dosing systems is used to dose and mix the chemicals sufficiently for treatment.Biological treatment is a part of wastewater treatment that uses living things to dispose of organic pollutants in wastewater. The municipal wastewater equipment used for the biological processes consists of an aeration tank, clarifier, and biological Reactor. These components create ideal habitat conditions for microbes and enhance their activities for the decomposition of organic substances and nutrient removal processes like nitrogen and phosphorus. Sludge handling is a very important segment of the sewage process with the quantity of sludge generated being very large in industrial applications. Facilities for sludge thickening or dewatering may also be available in the municipal wastewater equipment for sludge management. These systems aid in the sludge thickening and its concentration, drying, and dewatering to minimize its volume and enable safe disposal and reuse.
