Polyaluminium chloride used to deal with oil wastewater Wastewater from oil wastewater Many industries, such as oil and wastewater treatment of galvanized and color coated production line, gutter oil pollution, construction of marine oil produced wastewater, can be used to deal with polyaluminum chloride , Polyaluminum chloride is a polyhydroxy, polynuclear complex of cationic inorganic polymer flocculant mainly for purified drinking water, but also for the special water treatment of water, in addition to iron, except cadmium, fluoride removal, in addition to radioactivity Pollution, in addition to oil slick. Also used for industrial wastewater treatment, such as printing and dyeing wastewater, casting, papermaking, medicine, leather and so on are also widely used. Polyaluminum Chloride is used to treat oil-contaminated wastewater Add polyaluminum chloride (solid) to room temperature water at a 1: 3 weight ratio while stirring, until completely dissolved, then dilute with water to the desired concentration. Raw water turbidity 100-500mg / I, the dosage of 3-6mg / I, the specific dosing, the water quality should be based on the small test, select the best dosage, and then put into use. After flocculation there is a lot of flocculation material floating in the pool surface, these substances need to be removed by other means, such as the scraper scraping away, special net fishing away. You encounter there are reservoir floats, indicating insufficient dosage or not fully mixed with the sewage mixing, on the one hand, but also to determine the oil wastewater treatment is which industry wastewater, the acidity of the wastewater is alkaline.
