Sea Water Desalination

A river, lake or dam is a natural watercourse, usually freshwater, flowing toward an ocean, a lake or another river.

The chemistry of the water has a large impact on the ecology of that water for both plants and animals and it also affects the uses that may be made of the river water.

Rivers are increasingly managed for habitat conservation, as they are critical for many aquatic and riparian plants, resident and migratory fishes, waterfowl, birds of prey, migrating birds, and many mammals.

Due to low maintenance cost and effective removal of biodegradable organic matter biofiltration and ozonation is becoming attractive drinking water treatment method. It decrease the presence of disease causing microorganism and disinfection byproducts in drinking water The operation of water treatment facilities may seriously compromise safety, sustainability and cost efficiency of water supply system. Even more it will compromise public health.

Natural Organic Matter in water is a major concern and should be removed from drinking water

 Objective and scope:

ozonation is introduced in more and more water treatment plants as a replacement of primary chlorination in order to control the  formation of chlorination by-products. Because ozone is a strong oxidant, it can be used not only for disinfection but also for removal (oxidation) of organic substances. Ozone is used for the treatment of water polluted with pesticides or other anthropogenic substances. Ozonation can be combined with UV and H2O2 treatment

in order to increase the oxidation power. Such advanced oxidation processes The principle of biofiltration is to utilize bacteria and protozoa, which are Attached to the surface of filter materials, to clean water from undesirable substance in drinking water. The biofilters are used for removal of biological organic matter, iron, manganese, sulfate, nitrate, pesticides, taste and odor causing substances and algal metabolites. . In groundwater and small surface water treatment plants, ozonation- biofiltration may be used as the only unit processes The process often includes pre-ozonation to provide primary disinfection and also to aid coagulation/flocculation.
After coagulation/flocculation and sedimentation or filtration or both, an intermediate ozonation is often applied for disinfection. This is usually followed by biofiltration where granular activated carbon is normally the filter media, and a disinfection step.

Chemtronics providing water treatment process in which ozonation is combined with rapid filtration though media populated with bacteria.
