Process for cleaning contaminated waste water containing detergents
Description
Precipitation of the greases, oils and fats is carried out to cleam the waste water from a nuclear power station. This is done by adding activated carbon KMnO4, MnSO4 and CuCO3 and mixing and increasing the pH value to 8.5-9 by adding ammonia. The waste water then passes through an evaporator and a mixed bed filter, and the purified water is returned to the water circuit of the station. (RW)
