Founded in 2004, Vision Earth Care is committed to work towards a green tommorrow by providing the most effective eco-friendly solutions to water treatment across all scales. The technology used is no more complicated than the one used in your lawn, however the results are no lesser than the best you can expect. We call it VisionE Soil Bio-Technology (SBT): an evergreen everlasting biological purification engine.

The technology has been developed by the reasearch group at Indian Institute Of Technology (Powai), and the same has been patented. 
US Patent granted no. 6,890,432 B2

We are located at SINE, Society for Innovation and Entrepreneurship, hosted by Indian Institute of Technology Bombay. 
SINE has been extending the role of IIT Bombay by facilitating the conversion of homegrown research into entrepreneurial ventures.

Our technology is based on a bio-conversion process where fundamental reactions of nature, namely respiration, photosynthesis & mineral weathering take place in a media housing micro & macro organisms which bring about the desired purification. SBT is an oxygen supplying biological engine and so the process can treat all types of water – domestic municipal & industrial. SBT is suitable for treating water with salinity <10,000 mg/L. Moreover, there has been developed an advanced version of SBT called "CAMUS-SBT" which is capable of even higher levels of purification.

The process requires mesophyllic temperatures; so where the ambient temperatures are low/ very low a greenhouse infrastructure appropriate for the local conditions houses the SBT plant. However the process can work at high ambient temperatures.

Our facilities consist a raw water tank, bioreactor containment , treated water tank and where appropriate a greenhouse and associated piping, pumps & electrical.

Water or waste water is pumped over the bioreactor; the suspended solids are removed by the top media which is scrapped and discarded into municipal solid waste. The water trickles into the bed and treated water collects in the filtrate tank. Recirculation pumps are provided to obtain desired hydraulic retention times; in general purification to desired quality is achieved in one pass and so these recirculation pumps are not used.

Process flow description:

CAMUS-SBT is an oxygenation engine that outperforms conventional technologies

Like Activated Sludge Process (ASP), Sequential Batch Reactor (SBR), Membrane Bio Reactor (MBR) and Moving Bed Bio-reactor (MBBR). Our technology harnesses a special set of bio-chemical reactions to deliver the oxygenation required for effluent treatment.

In conventional technologies, aeration is achieved mechanically, which is very energy intensive. At higher ambient temperatures (like in India) the solubility of oxygen in water is low, therefore energy requirements of mechanical aeration used by conventional technology increases. Moreover, air contains only 20% oxygen, the rest being nitrogen that is passed into water wastefully, further adding to process inefficiency.

CAMUS-SBT resolves this problem using a bio-chemical method of oxygenation, which not only uses the atmospheric oxygen, but also uses the nitrogen from the atmosphere in a specially engineered ecology to achieve the desired level of purity.

In addition conventional technologies generate large amount of sludge for which additional disposal facilities have to be created. CAMUS-SBT does not face any such problems.

We are at SINE of IIT B which has been set up as an umbrella for homegrown technologies.

We work in close association with IITB and we have ready access to the latest innovation relating to the technology developed by Prof H.S.Shankar of Chemical Engineering Department.
