 OILY WASTE WATER TREATMENT

Under make in India initiative a new indigenous waste water treatment technology has been developed in India, which uses a cobination of electrocoagulation and electroflotation enhanced membrane module (ECEFMM). 

Electrocoagulation: It is a wastewater treatment techniques that uses electrical charge for charging the particles surface charge, allowing suspended matter to form aggregates.

Electroflotation: It is the separation of suspended particles from water using hydrogen and oxygen bubbles generated by passing electricity through water.

Treatment Process: In the developed module electrocoagulation and elecroflotation are adjoined with membrane in a single setup. The turbulence created because of hydrogen bubbling throuh the feed medium or the wastewater, resists the deposition of oil over the membrane. The synergistic effect of hydrogen bubbling and rotation of membrane module creates substatial turbulencewithin the solutionand on membrane surface. On application of electric field oil separation through membrane its fouling is substantially reduced and membrane longevity is also inhanced by restricting the membrane ageing for prolonged time period. unlike other conventional treatment, it can breake highly stable oil water emulsion through electric discharge and simultaneously separate oil from waste water with high efficiency.

Benefits: 

  • The removed spent oil from oily waste water can be further used as an industrial burner oil, furnace oil, mould oil, hydraulic oil,and so on. 
  • Thus it creates addtional revenue generation scope for low income groups by selling this collected spent oil.
  • Reduces water pollution 
  • less costly 
  • It can be installed at Garrages for treatment because it requires less areas.

 ALGAL BLOOM   Keywords :  Alga (singular subject/ noun) Algae ( plural subject/noun) Mycrocystis (alga) microcystin( toxin / poison) DO: oxygen dissolved in water, generally 4mg/l required to sustain the life in water.  Eutrophication   (Neutrients enrichment in water bodies ) : The excess of fixed nitrogen builds up in streams and lakes where provides extra food for microorganisms and causes a bloom in the population of algae. The algae population eat up oxygen and eventually, brings the waterbody on the brinks of death. Algal bloom in river  Algal bloom( algal pollution) is a condition of excessive sudden  population growth of algae on the surface of water bodies in mat form because of sudden increase of nutrients like nitrogen and phosphorus that leads food chain disturbance in water bodies. Actually microscopic plants( algae) are unicellular, aquatic, roots, and leaves. Algae are required nutrients for growth by the process of photosynthesis; ...
