3d Round-Table; 2nd Industrial Driven Event Regular working meeting within the scope of the MemBridge project activity was held in Astana on June 21-22. The main theme of the meeting was the development of ZLD (Zero Liquid Discharge) technologies. These hybrid technologies provide zero discharge of liquid waste. The production string includes electro- and pressure driven processes, as well as vaporizers which allow obtaining the solids as the final residual product. For example, hardness salts initially contained in raw water, will be the final solid residues after the process of water preparing for a power plant. Waste dump is the one of possible ways of deliverance from these residues. But even in this case, the volume of discharges, compared with conventional methods resulting in liquid waste, is tens times reduced. Other fields of utilization are more interesting: as a filler of cement mortar used in construction, the use of salt or brine against icing of roads and others. |
