In contaminated water process of removing biological contaminants, gases, undesirable chemicals and suspended solids is water purification. Drinking water without purification is disinfectant and leads to many different types of diseases. Sedimentation, filtration, distillation, slow sand filters, chlorination and flocculation are also including in the process purification. After rain water had fallen in the ground it slowly started affecting by matter such as bacteria, algae, fungi, parasites and fungi. When one drink this kind of water it leads to severe disorder. In governments a particular quality in drinking water has set up. On seeing the water it is not possible to know about the water quality. By doing boiling and using activated carbon filter it is not possible to treat all contaminants in water. According World Health Organization report done in 2007, due to diarrheal disease 1.8 million people died per year. In that it estimated that 94% of diarrheal diseases are due to intake of contaminated water. Groundwater, Lakes, reservoirs, rivers, canals and rainwater harvesting are some of the sources of water.
Some of diseases which occur due to use of unsafe water are Campylobacteriosis, Cholera, E. Coli Infection, Dysentery, Salmonellosis and waterborne disease. Pathogenic microorganisms present in contaminated water cause waterborne diseases. In 17th century water filtration’s first experiment done. In suspended water small particles are first observed through microscope by Robert Hook and Antonie van Leeuwenhoek. Using chlorine in drinking water was attempted successfully by John Snow which helps to prevents cholera. In year 1905 it started permanently to use chlorine in water when typhoid fever appeared in England. Purification of water has calculated according to the pH value present in water. If pH value is near to 7 that kind of water is pure water. It ranges from 7.5 to 8.4 in sea water. In acidic pH value is < 7 using soda ash, lime or sodium hydroxide it raises to reach the necessary level.
Particles present in contaminated water are organic particle and inorganic particle. Organic particles are bacteria, virus, algae and protozoa are organic particle whereas silt and clay are inorganic particles. Under Coagulation process organic and inorganic particles separated, this is the first step in water purification. After coagulation process water enters in to sedimentation basis for process of sedimentation. Inclined plates present in sedimentation basis (smaller than sedimentation basis) used to separate particles. Sludge which stored in bottom of tank after the particles will get separated in sedimentation basis. Particle will not remove easily from solution to use Dissolved air flotation (DAF). Water flows in to dissolve air flotation tanks after coagulation process gets finished and create fine bubbles. Final step in water purification is filtration after removing all unneeded particles. Some types of filtration are Rapid sand filters, slow sand filters and membrane filtration. Removal of ions will do by ultra filtration membranes, Ion exchange, Electrode ionization and Preciptative softening. Adding disinfectant chemicals and removing micro-organisms will do by disinfection which gives odour, taste and appearance to drinking water.
Why to choose Adya Clarity?
Modern type purifier is of two types RO (Reverse Osmosis) purifier and UVRO (Ultraviolet Reverse Osmosis) purifier is available in market. Purifiers are available in different shape, size and capacity of water storage. Adya Clarity plays a vital role in purifying industry and leads in industry. It is an international company in purifying and they turn contaminated water into mineral rich water. It removes bacteria, Ecoli (4 types) and removes fluoride from contaminated water. It is the best idea of choosing its purifying water to lead life healthy without any water diseases. Adya Clarity water will always consider as “King of water”.
