Most of our rivers are highly polluted as well as our lakes, ponds and other water bodies.The recent CAG Report of 2009 and 2010 says that the rivers are severely polluted .A CAG report on Bangalore says that- 100 million liters of untreated sewage is let into the rivers, lakes and this river water in turn is used by farmers in downstream for growing crops and we eat such food grown by polluted water. CAG report blames BWSSB to take moral responsibility of handling sewage and to treat them before letting into river, lakes etc. But sewage treatment is costly , sewage is spread out.So should we allow or rivers , lakes and other water bodies to be polluted??

Objective- Polluted water is a serious health hazard and it is desirable to clean up rivers, lakes and all water bodies from the water borne organic wastes generated from the pollutants and sewage so that waste is converted to wealth by producing more fish and thus increasing the per capita income of fishermen

Our Solution: In water, growing algae has the capacity to consume nutrients and absorb CO2 and release oxygen by photosynthesis. Diatoms is one of the species which contribute to about 50% of world’s food produced in oceans.
An organic solution that can grow diatom algae in any water – saline, fresh water, polluted water, sewage water etc is used to clean and reuse the waste water. The growth of diatoms is very fast and happens within 5 minutes and continues till the nutrients lasts. The growing diatoms absorb CO2 and release O2 at micro plant level. The O2 helps aerobic bacteria breakdown organics into its constituents and thus cleans up the waste water. The suspended solids break down into nutrients, gases and sludge. The nutrients are further absorbed by the diatoms to grow.
The diatom algae produce food by photosynthesis and this becomes food for zooplankton. Zooplankton in turn becomes the food for the fishes. Therefore, by making use of this natural process, to clean up any water bodies such as river, lakes. If there are no fish the zooplankton become part of sludge and become excellent manure for plants. There is no bad smell in water and in sludge. The dissolved oxygen content of treated water improves considerably.
