High Salinity Wastewater Treatment

Product Detail

Brief Introduction

High salinity wastewater is produced during chemical production, landfill leachate or reverse osmosis process, it is a kind of wastewater which has COD50000-100000mg/L, 5%-15% salinity content (50000ppm-150000ppm) and it is very difficult to process. Because of high organic content and Ca2+?Mg2+?Si4+ concentration, conventional evaporator or MVR couldn’t work for a long time because of scale formation. Even liquid incineration system will be blocked up because of high salinity.

The system is specially designed according to the feature of high salinity wastewater, it could overcome interaction between organic stuff and salt, and could separate the salt content out of organic wastewater. Salt ingredients will be crystallized, organic solvent could be recovered.

The treatment system is consisted by two parts: one is concentration device (concentrate the raw liquid to 18% salinity content, it is available to choose MVR based on salinity type), the other is desalination device (We own invention patent), which could distill the high salinity wastewater to solid in one step.

Application

High salinity wastewater such as waste leachate and pharmaceutical extraction liquor
