RESEARCH OF CHEMICAL PROCESSES OF WASTEWATER TREATMENT

Annotation. Treatment of waste water of industrial enterprises from heavy and toxic metal ions is carried out by traditional reagent method, sorption and membrane technologies. One of the simplest, cheapest, available and effective methods is sorption purification. The peculiarity of the sorption cleaning method is the property of selective absorption from multicomponent solutions and high cleaning efficiency. Treated wastewater can be used in the water supply system of technical circulation. The main of the research work is to study the pH of natural adsorbents in flowing and clean water solutions, particle sizes in suspensions, sedimentation rate and adsorption properties of natural adsorbents for sorption purification of industrial wastewater from toxic metal ions. natural minerals from Almaty region have high sorption properties, that is, they can be used for sorption treatment of industrial wastewater
