Water Pollution and Treatment
Waste water pollution is caused due to discharge of waste water from industrial and commercial waste into surface waters; untreated discharge of domestic sewage, chemicals into flowing surface waters and disposal of waste and leaching into ground water; eutrophication. The various methods of contamination of wastewater require a variety of strategies to remove the contamination. The various treatments are brine treatment, brine management, solids removal, oil and grease removal, hydro cyclone oil separators, removal of biodegradable organics etc.
The technologies can be designed to provide low cost sanitation and environmental protection while providing additional benefits from the reuse of water. The process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water is called as water purification. Various techniques are available to remove micro-organisms through water purification.
The various laboratory test methodologies are wastewater quality indicators. They are used to assess suitability of wastewater for disposal or re-use. Tests measure physical, chemical and biological characteristics of the waste water.
