(0.001 micron) and gain the name, the operating range of nanofiltration between ultrafiltration and counter-infiltration, it retain organic matter molecular weight about
It is low to the removal efficiency of monovalent anion salting liquid between the ability of retention dissolubility salt is 20~98% for 200~400 or so
In high-valence anion salting liquid, such as removal efficiency of sodium chloride and calcium chloride is 20~80%, and the removing of magnesium sulfate and sodium sulphate
Rate is 90~98%.Counter-infiltration is most accurate embrane method liquid separation technology, and it can stop that all dissolubility salt and molecular weight are big
In 100 organic matter, but hydrone is allowed to pass through, cellulose acetate reverse osmosis film salt rejection rate can typically be more than 95%, counter-infiltration
Composite membrane salt rejection rate be generally higher than 98%. they be widely used in seawater and brackish water desalination, boiler feedwater, industrial pure water and electronics
Prepared by level ultra-pure water, drinking pure water production, the process such as wastewater treatment and special separation can using counter-infiltration before ion exchange
Operating cost and wastewater discharge is greatly reduced.
Nanofiltration is formd nanofiltration and counter-infiltration sewage by current many sewage disposal enterprises with dividing infiltration technology to combine
Processing system, but nanofiltration and counter-infiltration sewage disposal system, front end must be provided with the pre-processing device of correlation, and sewage is carried out
Early stage filters, and can be only achieved expected purpose, and the scientific of pre-processing device filtering early stage influences later stage nanofiltration and counter-infiltration
Effect；In addition the scientific effect for also influenceing sewage disposal that nanofiltration pond and counter-infiltration pond are set.
