Water Treatment
Background
- Many water scarcity areas in our country suffer from paucity of resources and poor planning
- We waste a lot of water being a gift of nature
- This leads to water scarcity
- There is urgent need to understand its value, plan its use and conserve it
- Efforts to harvest every drop of rain are essential but not enough
- Reuse and recycle will help us replenish the depleted ground water
- Proper treatment of waste water will help in cleaning up the natural sources of water
Purpose
- To create awareness of simple indigenous technologies to treat water for recycling and reuse
- Overcome scarcity with recycle and reuse using economically and technically viable solutions
- Offer a solution that is light on investment and simple to operate
Technology
- Natural process of cleaning by using bio-filters
- Few external chemicals used for treatment
- No wastage No sludge No obnoxious smell
- Every component of out put useful
- Simple to establish and easy to operate
- Low power consumption
- Except small water/sludge pumps no moving part
- No corrosion No erosion
- Low cost of operation
Benefits
- Low processing cost
- ?Excellent results Consistent results
- ?Indigenous technology with complete support
