Water purification is the process of removing undesirable chemicals, materials and biological contaminants from raw water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water) but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharma, chemical and industrial applications. In general the methods used include physical process such as filtration and sedimentation, biological processes, chemical process such flocculation, chlorination and use of electromagnetic radiation such ultraviolet light. The technologies used for treating the water is highlighted below
Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential, a thermodynamic parameter.
1. Industrial RO System
2. Domestic RO System
Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water is more compatible with soap and extends the lifetime of plumbing. Water softening is usually achieved using lime softening or ion-exchange resins.
Filter is used to removal of suspended solids present in the water. Types of Filters,
1. Pressure sand filters
2. Dual media filter
3. Activated carbon filter
4. Iron removal filter
When the dissolved solids in the water are to be almost completely removed by a demineraliser is used. A demineraliser essentially consists of a cation exchanger and anion exchanger.
When water with very high purity is required a mixed bed polisher is used. The mixed bed polisher unit contains strongly acidic cation resin and strongly basic anion exchanger resin in a mixed form. The water passing through the mixed bed exchanger comes successful in contact with cation and anion resin. This corresponds to an infinite stage demineralising process and ensures high purity treated water.
