ZeroLiquid Discharge (ZLD) is a treatment process specifically designed to removeall liquid wastes from a septic tank system without draining it. The main focusof ZLD is to reduce wastewater water consumption by 80 percent whileeliminating solids that are not dissolved in the wastewater. It can reduce aseptic tank's water usage by as much as 40 percent and eliminate sewerback-ups. By using this technology, wastewater treatment plants are able to useless energy to produce high quality, disposable drinking water, therebydecreasing their greenhouse gas emissions and their impact on the environment.Furthermore, since most of the wastewater in most states is disposed of bytreated sewers, this technology can be applied to help restore aquaticecosystems back to normal.
Zeroliquid discharge refers to thepractice of dewatering using biologically active carbon sequestering systems asa means of reducing the discharge of harmful substances into the environment.Carbon sequesters are nutrients that recover through biological oxidationprocesses and provide a continuous source of carbon at a low cost. Biomassrecovery, when used in conjunction with water reuse systems, offers the bestmethod of environmental management in regards to increasing water availabilityand reducing water scarcity. The increased availability of water allowscommunities the ability to fulfill their water needs through water reuse.
