IMMT shows green way for wastewater treatment A team of City-based CSIR-Institute of Minerals and Materials Technology (IMMT) has developed a wastewater treatment technology which can be set up with a minimum capital and run without electricity, chemicals or machineries. The technology named ‘Constructed Wetlands for treating wastewater’ is ideal for treatment of domestic and municipal wastewater in cities. http://www.newindianexpress.com/states/odisha/2016/nov/09/immt-shows-green-way-for-wastewater-treatment-1536566.html

  1. True Mr. Tyagi. Moreover, this is age old technology and due to its constraints other technologies developed.

  2. Constructedwetland may be suitable where adequate land is available, not at housing estates and IT complexes.

    2. You are correct Paritosh, constructed wetlands require a lot of land.  I have set up 2 in the State of New Mexico.  However, since 1973, I have been designing and building algae-based wastewater treatment facilities partly based on the original concept of the late Prof. William J. Oswald.  He was one of my mentors and I cut my teeth in this area of technology working with him on 2 facilities in Israel.  My design is a modified high rate algae pond type of facility.  It requires about 5% of the land area of a constructed wetland. The CAPEX is about 20% of the typical high cost, energy energy consuming type of facility that is built in most Western countries.  The OPEX of my type of facility is also about 5% of the typical Western type facility.  I have designed my type of facility for a plant which will soon be built and operating in Uttar Pradesh.
