Water Filtration Process In Hindi

Most industries produce some wastewater recent trends have been to minimize such production or.

Water filtration process in hindi.

A water filter is a device which removes impurities from water by means of a physical barrier chemical and or biological process. Water purification is the process of removing undesirable chemicals biological contaminants suspended solids and gases from water. A water softener typically uses sodium or potassium ions to replace calcium and magnesium ions the ions that create hardness. Water either from the source or more commonly from pre treatment processes is applied to the top of the filter.

Rapid sand filtration is much more common than flow sand filtration because rapid sand filters have fairly high flow rates and require relatively little space to operate. It then flows downward. When the filtration is started after being backwashed there will be little head loss. Water purification process by which undesired chemical compounds organic and inorganic materials and biological contaminants are removed from water that process also includes distillation the conversion of a liquid into vapour to condense it back to liquid form and deionization ion removal through the extraction of dissolved salts.

Rapid sand filtration is a physical process that removes suspended solids from the water. One major purpose of water purification is to provide. Removal takes place by a number of mechanisms that include straining flocculation sedimentation and surface capture. Aside from its use to purify drinking water the technique is widely applied for purification and separation of a variety of industrially and medicinally.

Filters can be categorised by the main method of capture i e. In fact during rapid sand filtration the water flows at a rate up to 20 metres per. 1 water treatment plant 2 water purification plant 3 water clarifier plant 4 mineral water plant 5 drinking water treatment plant 6 water pre treatment plant. The water level above the filter bed is usually kept at two to six feet.

Ion exchange usually describes a processes of purification of aqueous solutions using solid polymeric ion exchange resin more precisely the term encompasses a large variety of processes where ions are exchanged between two electrolytes. Straining or deposition within the media i e. Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by product. Exclusion of particles at the surface of the filter media i e.

Ultrafiltration uf is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. After treatment the treated industrial wastewater or effluent may be reused or released to a sanitary sewer or to a surface water in the environment. Most water is purified and disinfected for human consumption drinking water but water purification may also be carried out for a variety of other purposes including medical pharmacological chemical. The goal is to produce water fit for specific purposes.
