Water filtration process in hindi.
In fact during rapid sand filtration the water flows at a rate up to 20 metres per.
Filtration is a process that removes particles from suspension in water.
Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by product.
One major purpose of water purification is to provide.
A water filter is a device which removes impurities from water by means of a physical barrier chemical and or biological process.
Aside from its use to purify drinking water the technique is widely applied for purification and separation of a variety of industrially and medicinally.
Rapid sand filtration is a physical process that removes suspended solids from the water.
The goal is to produce water fit for specific purposes.
Filters can be categorised by the main method of capture i e.
It then flows downward.
Straining or deposition within the media i e.
Suspended solids and solutes of high molecular weight are retained in the so called retentate while water and low molecular weight solutes pass through the membrane in the permeate filtrate.
Water either from the source or more commonly from pre treatment processes is applied to the top of the filter.
Exclusion of particles at the surface of the filter media i e.
Removal takes place by a number of mechanisms that include straining flocculation sedimentation and surface capture.
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.
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.
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.

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.
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.
Ultrafiltration uf is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane.
The water level above the filter bed is usually kept at two to six feet.
