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.

   force of law except pulse MSR nanofiltration technology is mainly sulphate process
