Sewage treatment coagulant and flocculant have good effect when used together

In Coagulant (Polyaluminum Chloride, commonly known as water purifying agent, also known as polyaluminum chloride, polyaluminum for short, PAC) and Flocculant (polyacrylamide, belonging to high molecular polymer,  PAM) Under the action, the suspended matter undergoes physical flocculation and chemical flocculation, thereby forming large suspended matter flocs. Under the buoyancy of the bubble group, the “floccules” float to the liquid surface to form scum, which is separated from the water by using a slag scraper. Cleaning the nozzle will not cause clogging, and the use of coagulant and flocculant in sewage treatment is effective.

Coagulant (polyaluminum chloride, commonly known as water purifier, also known as polyaluminum chloride, referred to as polyaluminum, PAC) is mainly used for the purification of drinking water and industrial wastewater, and the treatment of special water quality (such as oily sewage, Printing and dyeing papermaking sewage, smelting sewage, containing radioactive properties, toxic heavy metals such as Pb, Cr and sewage containing F, etc.), in addition, it is also widely used in precision casting, oil drilling, leather, metallurgical papermaking, etc., coagulant is used in water During the treatment process, the colloidal particles in the water can be bonded and aggregated together. Usually, the coagulation process is to add chemicals during the water treatment process to cause impurities to coagulate, decolorize, remove suspended solids, remove turbidity and bacteria .

Polyaluminum ferric chloride has good coagulation effect. Polyaluminum ferric chloride (PAFC) is a new type of high-efficiency inorganic cationic composite flocculant. It has the advantages of wide surface, good turbidity removal effect, and small corrosion to equipment pipelines; it also has the characteristics of fast iron salt flocculant flocculation settlement, easy separation, good performance in low temperature water treatment, and wide range of PH value in water treatment. At present, polyaluminum ferric chloride has been successfully used in the treatment of drinking water, industrial water and various industrial wastewater.

Coagulant (polyaluminum chloride, commonly known as water purifying agent, also known as polyaluminum chloride, referred to as polyaluminum, PAC) has strong decolorization and decontamination capabilities, and the water purification effect is 4-6 times that of AL2(SO4)3. 3-5 times the amount of ALCL3, the dosage is small, the effect is large, the cost is low, the benefit is high, the adaptability to a wide range of pH value, the reduction of the pH value of raw water is small, so it has no corrosion effect on pipeline equipment, no need to add other additives, and the flocs form quickly However, it is thick, has high activity, high sinkability, and fast precipitation, so the purification effect on high turbidity water is particularly obvious.
