Mine water nanofiltration salt separation device

Mine water nanofiltration salt separation deviceNanofiltration (NF): capable of intercepting substances at the nanoscale (0.001 μ m). The operating range of nanofiltration membrane is between ultrafiltration and reverse osmosis, with a molecular weight of about 200-800 MW for intercepting organic matter and a capacity of 20-98% for intercepting dissolved salts. The removal rate of soluble monovalent ions is lower than that of high valent ions. Nanofiltration is generally used to remove organic matter and pigments in surface water, hardness and radium in groundwater, and partially remove dissolved salts. It is used for the extraction and concentration of useful substances in food and pharmaceutical production.

Nanofiltration can intercept ions above divalent and other particles, and only allows water molecules and some monovalent ions (such as sodium, potassium, chloride ions) to pass through.Mine water nanofiltration salt separation device
