Description
Summary:The article proposes an adsorption technology for the treatment of salt wastewater and concentrate of reverse osmosis plants to remove sulfates and chlorides by multi-tonnage waste from the energy industry — chemical water treatment sludge formed at the wastewater pre-treatment stage. Curves of adsorption of sulfate and chloride ions by granular sorption material in dynamic conditions were obtained. According to the Shilov equation, the time and coefficient of protective action of the loading layer during adsorption purification from sulfate and chloride ions under dynamic conditions were calculated. The basic technological scheme of the pilot wastewater treatment plant and reverse osmosis concentrates of the plant at PJSC Nizhnekamskneftekhim is proposed. The economic benefit and prevented environmental damages implemented using this technology are calculated.
