Waste water treatment
Through the natural water cycle, the earth has recycled and reused water for millions of years. Water recycling, though, generally refers to projects that use technology to speed up these natural processes. Nature has an amazing ability to cope with small amounts of water wastes and pollution, but it would be overwhelmed if we didn’t treat the vast quantities of wastewater and sewage produced every day before releasing it back to the environment. Treatment plants reduce pollutants in wastewater to a level nature can handle.
Water recycling also means reusing treated wastewater for beneficial purposes such as agricultural and landscape irrigation, toilet flushing, and replenishing ground water. Water recycling offers resource and financial savings.
Wastewater treatment can be tailored to meet the water quality requirements of a planned reuse. Recycled water for landscape irrigation for example requires less treatment than recycled water for flushing.
There are two types of waste water that is recycled – that which comes as sewage and that which comes as gray water – waste water from bathroom sinks, tubs, shower drains and clothes washing equipment drains.
Water Recycling Can Reduce and Prevent Pollution as well as save energy.
As the demand for water grows, more water is extracted, treated, and transported sometimes over great distances which can require a lot of energy. If the local source of water is ground water, the level of ground water becomes lower as more water is removed and this increases the energy required to pump the water to the surface. Recycling water on site or nearby reduces the energy needed to move water longer distances or pump water from deep within an aquifer.
Functionalforms has tied up with agencies and consultants in Auroville who advise us on and design small and large waste water recycling systems for our projects. The types of systems we use varies with the quality of water output required and we’ve put in place Aerobic as well as Anaerobic systems, sometimes combining both.
