Water Recycling and Reuse
I have read various articles on water reuse and recycling. Unfortunatelly this information mostly is provided by companies selling their products in this field, and to make it full I had the need to make a compilation of varioius articles.
The main idea of every article in this field is to pursuade the reader, that by reusing and recycling water, we can solve the problem of tightening fresh water supplies.
The authors show us that there is a wide range of products to recycle water and that their main difference is that part of them are biological, and the other part is chemical. And though the result is approximately the same, and the use of chemicals does not make a negtive effect on recycled water, yet when we make a comparison, we can see that the biological one is more expensive, obviously, because being friendly to the enviroment as usual costs us more.
The authors go on describing working principles of Membrane Bioreactor and Sequencing Batch Reactor.
Summing up I want to say that this trend on building and using water recycling reactors is useful and should take over the world as soon as possible, because with limited fresh water supplies globally, we need to have our focus on water recycling and reuse.

Well, what we’re seeing in the water industry, is a focus on going to more recycle reuse of wastewater. With limited fresh water supplies globally and tightening fresh water supplies, we’re seeing people wanting to reuse the water. Instead of just one time use, they want to recycle it back into their plants. What is water recycling? Recycle: verb a. To recover useful materials from garbage or waste b. To extract and reuse. Why recycle water? Recycled water can satisfy most water demands, as long as it is adequately treated to ensure water quality appropriate for the use. How is recycled/reclaimed water different from raw water? Through the natural water cycle, the earth has recycled and reused water for millions of years. Water utilities use technology to speed up these natural processes. The water conservation hierarchy (img) Inherent risk for alternative water sources (img) • rainwater • greywater • treated sewage • industrial water • managed aquifer recharge (MAR) • framework for alternative urban water supplies. Rainwater Using rainwater is an easy and effective way to conserve our water supplies and reduce the amount of mains water you use. Some simple guides have been produced on how to collect and safely manage rainwater. Greywater Greywater (all non-toilet household wastewater) can be a good water resource during times of drought and water restrictions, but its reuse can carry health and environmental risks.is reusable wastewater from residential, commercial and industrial bathroom sinks, bath tub shower drains, and clothes washing equipment drains. Gray water is reused onsite, typically for landscape irrigation. Treated sewage Recycling wastewater can ease the pressure on our water resources and avoid the need to discharge wastewater to the environment. Recycling wastewater can provide water that, with some management controls, is suitable for a wide range of uses including irrigation and toilet flushing.
