METHOD FOR TREATING SULFATE-, CHLORIDE, MERCURY- AND SELENIUM-CONTAINING WASTE WATER

摘要

The method according to the invention provides a method for treating a waste water, where (a) the waste water is provided having specific sulfate, chloride, mercury, and selenium concentrations, (b) the waste water (WW) is fed to a high pressure separator 1 using a high-pressure pump (P1) in which the waste water (WW) is separated into a permeate volume (PV) containing reduced sulfate, chloride, mercury, and selenium concentrations and a concentrate volume (CV), (c) and where the concentrate volume (CV) is separated using a cleaning apparatus 4 that reduces both mercury and selenium in the concentrate volume.
