Reclaimed water reuse and zero discharge

     The reclaimed water reuse and zero discharge process (“RRZD process”) involves advanced treatment of saline wastewater for reuse through combinations of ultrafiltration, reverse osmosis, high pressure reverse osmosis, and evaporation and crystallization. The quality of effluent from RRZD process meets or is even higher than the standards specified by the Reuse of Urban Recycling Water—Water Quality Standard for Industrial Uses(GB/T19923-2005) and the Reusing Wastewater Quality Standard for Industrial Circulating Cooling Water(HG/T3923-2007) and other standards, and such effluent can be used to replenish water of the circulating water system with wastewater reuse rate no less than 96%, realizing nearly zero discharge.

     Technical core: high reuse, simplified process, low cost, modular construction, and excellent environment

     High produced water reuse rate: The total produced water reuse rate reaches more than 96%, reducing environmental pollution and saving corporate water costs.

     Simple pretreatment process: TMF/TUF is used for softening pretreatment, simplifying the process and reducing the area occupied.

     Low operating cost: amount of flocculant is reduced, concentration ratio high, back-end evaporation volume reduced, and overall operating cost reduced.

     Modular process: Modular process design based on the characteristics of wastewater allows wider application scope of the process, especially suitable for the upgrading and transformation of existing process designs. In process transformation, only zero-discharge process equipment is added to back end of existing reclaimed water reuse system without changing existing overall process design, which increases the produced water reuse rate, and achieves near-zero discharge.

     Good environmental benefits: At the end of the process, recycling salt separation can be applied to minimize the production of hazardous waste.
