Do you know? Zero liquid discharge is water purify and saving process in this process water is purified and recycled; therefore, leaving zero discharge after the treatment cycle. Zero liquid discharge is an advanced dis usable saving method that includes ultrafine particle, reusable and fractional elector decolonization. Some power industry, as well as gas, petrochemicals, chemical, and other industries, produce large volumes of wastewater that must be managed. So these dis usable water are discharged via a plant outfall to a surface water body, an evaporation pond, or in some cases deep well injected. So there are growing environmental involvement regarding such discharge practices, which has resulted in the development of Zero Liquid Discharge processes. After purifying the water we are using for daily use as drinking, bathing, etc. and free of the water problem.
