Development of a method of combined treatment of different waste water
Treatment of electroplating wastes from toxic metal ions (Ñu, Zn, Fe, Ni, Cr) together or individually presenting was investigated. The method is based on waste water of fish-processing factories as reagent with increased concentrations of lipids and lipoproteids which saponify during addition of soda ash. In this process exchange with heavy metal ions take places after mixture of different waste water. Treatment efficiency varied from 99.2% (for Cr) to 99.9-100% (for other metals).
