“There is water, but little”This sentence shows the crisis that has engulfed most of the countries of the world, especially the arid region of the Middle East.
One of the solutions used to deal with this crisis is purification Gray waters is. Gray water refers to domestic wastewater, excluding toilet effluent, that is generated when bathing, washing dishes, or doing laundry..

a company Knowledge Base Iranian active in the field Nanohas presented a new technology that can be used to return gray water to the consumption cycle.!

This system based on microfiltration and ultrafiltration can recycle 70% of the water consumed by purifying gray water..
Car washes, stone cutters, and carpet cleaners are among the industries that require a significant amount of water, which after consumption becomes polluted and turns into gray water.. By using filters based on nano technology, it is possible to purify this water.
In this system, gray water is hybridized using membranes Nanostructure Multi-channel ceramic is purified and disinfected. The material of the membranes used in this device is ceramic, and the size of the holes of these membranes is determined by the engineers and specialists of this knowledge base company using Nano technology Engineered.

In two stages of microfiltration and ultrafiltration, this system cleans the incoming sewage and returns the water to the system for reuse.. In the microfiltration stage, fats, detergents and other macromolecules, as well as to a large extent microbes and microorganisms, and in the ultrafiltration stage, all microorganisms and even the carcasses of microorganisms are removed from the incoming water.. The final product will be quality water that meets domestic and international standards.

Also, the filters of this device can be washed with the reverse flow of clean water that is produced to prevent clogging of the membranes; In this way, the clean water is passed through the filter with a certain pressure against the flow direction and causes the holes to open.. As a result, the life of the membranes used in this device is between 5 and 10 years, depending on the type of wastewater used.
