Sanctify Kochi Project April-May 2012
The intent of the Market Place canal trial was to propose a solution that would re-establish the canal area as a healthy and living body of water that could be enjoyed by fish, aquatic plants, local residents, the merchants and visitors alike. The treatment area was selected because of the following criteria.
We have demonstrated our technical capability utilising eco friendly methodologies to clean heavily contaminated water bodies and our canals. The live trial was performed at the market canal close to the Rainbow Bridge on the Marine Drive walkway in Kochi, Kerala, India.
On first inspection the problems were identified as many fold, the first was the very high level of silt build up, dramatically reducing the natural tidal flow of water into and out of the canal. The canal is surrounded on all sides by an extensive fruit and vegetable market. Each day large volumes of organic waste were disposed of by the merchants directly into the canal waters.
The enzyme treatment broke down the organic contaminates into a food source readily available for consumption by the indigenous aerobic bacteria. The enzymes ability to break down the organic foods for the bacteria enabled them to consume faster, breed faster and grow faster. Naturally, as bacterial colony numbers increased, so did the consumption of the organic waste matter contained in the canal water and silt. Because of the diffusers, the anaerobic bacteria normally responsible for the creation of the toxic gases were unable to survive in the now oxygenated water environment. After 22 days of treatment the water from the canal was compared with the water from within the structures treatment area with the following results:
The success of the trial confirmed that the selected treatment protocols would be a beneficial solution to the Kochi canal pollution problems.
