Epoch Master® Polyaluminum chloride is widely used in domestic water, industrial water and other water purification treatment, urban sewage treatment, industrial wastewater, sewage, sludge treatment and sewage in some slag recovery, at the same time for some difficult treatment of industrial sewage, PAC as the mother, mixed with other agents, mixed into the compound PAC, Treating sewage can yield surprising results.Epoch master have a favorable price of Polyaluminum chloride. If you have any needs, you can contact us at firstname.lastname@example.org. Looking forward to your information.
Polyaluminum chloride is slightly acidic and non-toxic. After diluting with water, alkaline polynuclear complex or bridging complex with complex ion structure is formed, and finally alumina hydroxide is precipitated. In the hydrolysis process, accompanied by electrochemical, condensation, adsorption and precipitation physical chemical processes, so as to achieve the purpose of water purification.
Handling and storage
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Store the container tightly closed in a dry, cool and well-ventilated place. Store apart from foodstuff containers or incompatible materials.
Treatment of oily wastewater
Oil-bearing wastewater mainly refers to the large amount of produced water produced by the exploitation of crude oil in oil fields, the oil-bearing wastewater discharged by oil refineries and petrochemical plants, and the oil-bearing wastewater produced by the cleaning of oil tankers and vehicles. The treatment of oil-bearing wastewater mainly adopts the methods of oil separation sedimentation, air flotation and biochemistry. PAC combined with modified cationic polyacrylamide, flocculation precipitation filtration treatment of oily wastewater, has a very good treatment effect. Modified cationic polyacrylamide relative molecular weight can not be too high, and easy to compound with PAC to achieve the ideal effect.
Treatment of papermaking wastewater
Paper industry wastewater discharge is large, its middle section water accounts for a large proportion, and many paper enterprise black liquor after pretreatment (anaerobic, strong acid treatment, cellulose separation, neutralization, etc.) also mixed with the middle section water treatment.
dyeing wastewater treatment
Printing and dyeing wastewater has high COD, chroma and pH value, and admixture coagulation is a common method to treat it. Although PAC has good coagulation effect and low dosage required, its neutralization ability to printing and dyeing wastewater with high alkalinity is poor, and its application is limited to a certain extent. The traditional coagulant Al2Chemicalbook(SO4)3 was hydrolyzed to produce H+, which could neutralize alkali in printing and dyeing wastewater. It is proved that the two coagulants can reduce the treatment cost and improve the treatment effect of printing and dyeing wastewater by using the complementary advantages of the two coagulants and the synergistic effect of the same ion effect.
