　　Product Features

　　Ultra-low temperature evaporation

　　Shangchen SEV low-temperature hot pump evaporator maintains high vacuum to evaporate wastewater/waste liquid at room temperature as low as 30~37℃. For saline wastewater/waste liquid, low-temperature evaporation can greatly reduce corrosion to equipment. Low temperature is more suitable for heat-sensitive materials and materials prone to scaling.

　　High concentration, energy saving and high efficiency

　　According to different material characteristics, the amount of wastewater can be reduced by up to 90%~97%; heat pump technology is used to fully recover low-grade heat, and the comprehensive dehumidification ratio (SMER) is as high as 4.0kg·H20/kwh or more.

Evaporation Mother Liquor/High Concentration Waste Liquid Evaporative Water Recovery Equipment 

　　During the process of zero discharge of wastewater or evaporation and crystallization of saline wastewater, with the enrichment of impurity ions, high-boiling point substances, organic matter and other components in the mother liquor, the quality of the crystallized salt will decline or even the salt will not be crystallized, the evaporator will be seriously blocked, the evaporation capacity will decrease, the MVR steam compressor will vibrate violently and surge frequently, resulting in the evaporator being unable to continue operating. Therefore, many companies will discharge a small amount of evaporation mother liquor to maintain the balanced, continuous and stable operation of the evaporation system. The treatment of this part of evaporation mother liquor has always been a difficult problem for enterprises. Most enterprises outsource the disposal of evaporation mother liquor as hazardous waste, which greatly increases the burden on enterprises. The treatment of evaporation mother liquor has also become the key to achieving true zero discharge of wastewater from saline wastewater.

　　Evaporation mother liquor/high-concentration waste liquid to be treated

　　The water quality of the evaporation mother liquor is complex, usually with a very high salt concentration (TDS - generally above 20%) and a very high COD (generally above 100,000 mg/L), and it has the characteristics of strong corrosiveness, high viscosity, and high boiling point.

　　Currently, the treatment equipment for evaporation mother liquor/high-concentration waste liquid on the market includes single-effect evaporator, drying equipment, incineration equipment, etc., which have many problems such as high operating cost, easy corrosion of equipment, short life, and complex operation and maintenance. In response to the current situation in the industry, Shangchen has developed and launched special evaporation water recovery equipment for evaporation mother liquor/high-concentration waste liquid. It uses proprietary technology to solve the problem of evaporation mother liquor/high-concentration waste liquid disposal at a low cost.

　　Product Solution

　　The evaporation mother liquor/high-concentration waste liquid is first sent to the customized pretreatment system (optional) to remove suspended solids, COD, hardness or other substances that are not suitable for entering the evaporator, and then sent to Shangchen's special evaporator for evaporation mother liquor/high-concentration waste liquid. After evaporation concentration, crystallization or drying, recycled water, crystallized salt or solidified salt sludge are finally obtained.

　　There are two recommended solutions for Shangchen special evaporator for evaporation mother liquor/high-concentration waste liquid:

　　① For mother liquor/high-concentration waste liquid that is easy to crystallize, it is recommended to adopt Shangchen ultra-high temperature rise skid-mounted UltraMVR evaporative water recovery equipment;

　　② For mother liquor/high-concentration waste liquid that is not easy to crystallize, easy to coke, or has poor fluidity, it is recommended to adopt Shangchen RED low-temperature evaporation-drying coupled water recovery equipment.

　　Shangchen Ultra-high Temperature Rise Skid-mounted UltraMVR Evaporative Water Recovery Equipmentit is a proprietary high-temperature rise MVR technology developed on the basis of the standard skid-mounted ModMVRevaporator. It can increase the secondary steam temperature to 60'c, thereby concentrating and crystallizing high-boiling pointmaterials such as evaporation mother liquor and high-concentration waste liquid at a low cost.

　　The temperature rise of up to 60C means that more concentrated materials with higher boiling points can be processedwithout oroblems such as ow evaporation. compressor suroe and inabilitvy to crystalize salt due to insufficient heaexchange temperature difference.
