In addition to the sulfate method nanofiltration technology MSR

　　 Technical Overview
　　By heat exchange , pH adjustment, removal of free chlorine pretreatment means to adjust the salt water into the membrane requires using nanofiltration permeate monovalent ion rejection Second , the characteristics of the trivalent ion to achieve enrichment of sodium , sulfuric acid recycling the heat-sensitive sodium , sodium sulfate and sodium chloride to achieve separation by freezing equipment requirements are met of salt and brine byproduct of sodium sulfate decahydrate  .
　　Technical Features
　　 force pulse MSRTM membrane denitration technology uses physical method of separating sodium sulfate from the brine , except without adding nitrate agents, non-toxic, non-waste, waste gas and waste emissions.
　　 force pulse MSR special membrane, adapted to the special conditions brine removed nitrate, sodium sulfate and sodium chloride separated neutral conditions, long service life.
　　 cyclic process , operating off a large degree, so nanofiltration membrane to run at the lowest transmembrane pressure , the best membrane surface flow conditions, stable production.
　　 sodium sulfite reduction to remove free chlorine, on-line instrumentation, avoiding contamination of the activated carbon particles and SiO2 film .
　　 using PLC or DCS control, and signal measurements with high flow, temperature, level and other transportation elements, as well as high-quality electrical components. During the operation contains detection logic control, process parameters, display and other functions . Coordination before and after the process to ensure that the contract means at all times maintain a steady state.
　　 concentrate sodium concentration can reach 60 ~ 70g / L, in addition to nitrate by freezing process, brine closed loop waste "zero emissions" to avoid environmental pollution, improve the utilization of saline.
　　 refrigeration unit may use high temperature -5 ~ 0 ℃ Freon direct evaporation, may also be employed in indirect heat exchange chlor chilled brine freezing station provides .
　　 Scope
　　Chlor-Alkali Chemical various types of electric groove, all kinds of production , different materials produced caustic salt salt water, pharmaceutical and pesticide industry high salinity wastewater, chemical, printing and dyeing industry wastewater.
