Research work has been carried out on deep purification of water samples taken from industrial wastewater formed in the oil-producing industry containing hydrophilic and hydrophobic (²oil-in-water² and ²water-in-oil²) emulsions from oil and organic suspended substances. Using the coagulation method developed by us, industrial wastewater samples were purified up to 100% from oil and suspended substances under optimal conditions. It has been substantiated that this method is of great economic and environmental importance. The applied coagulant and extractant meet the requirements of environmental safety
