Water purification is the process of removing impurities and contaminants, making the water clean. Various techniques efficient in doing so include: • Reverse Osmosis • Electrodeionization(EDI) • Ion Exchange • UV Light treatment • Filtration
Need for Water Purification • Some major reasons why water purification is essential are: • To remove unnecessary bacteria and viruses • To remove chemicals and insecticides • Reducing chlorine and mineral content • Removal of toxins • To make water clean and odorless
Water purification overview • The process of filtering and purifying water involves a number of stages. • These stages include free chlorine disinfection, membrane filtration, reverse osmosis and oxidation or advanced oxidation. • Each stage helps with the removal of unhygienic substances or particles.
Water Filtration Stages • The five basic stages of a water filtration procedure include • Screening • Coagulation • Sedimentation • Filtration • Disinfection
Activated Carbon Filter for Water purification The process of using activated carbon to as a water purifier is called adsorption. Activated carbon is effective in removing sediment, chlorine and volatile organic compounds along with taste and odor from water.
Reverse Osmasis for Water Purification Reverse osmosis or RO filters are the most common types of water purification filters. This technology uses a semipermeable membrane to separate ions, molecules and other particles from the water.
Reverse Osmasis Water Filters for Industries Industries used Reverse Osmosis (RO) filtration to remove unwanted minerals from boiler water in power plants. The process is repeated multiple times to avoid corrosion caused by water deposits.
UV Filtration Treatment for Water Purification The UV water purification procedure uses UV-C rays to inactivate and destroy 99.99% harmful microorganisms that cause diseases. Unlike chemical disinfection, the microorganisms have to defense against UV light.
Household Water Ionizers A Water Ionizer or Alkaline Ionizer is a household apparatus which raises the pH of drinking water. This is done using electrolysis, where water from the source is split into alkaline and acidic components. The alkaline stream is also said to have certain health benefits.
