Aluminum plant sewage how to quickly become "clean water"? The key is actually this chemical!

In the "double carbon" goal, green manufacturing has become a new era of transformation and development of industrial enterprises must be the way. Aluminum industry is China's "dual-carbon" action in an important area, to enhance its sewage wastewater treatment capacity, to improve the quality of the water environment, the construction of green factories is of great significance.

What are the sources and types of aluminum surface wastewater?

Aluminum processing needs to go through extrusion (hot extrusion, cooling, stretching, cutting, etc.), oxidation (degreasing, alkaline etching, neutralization, anodizing, coloring, etc.), electrophoresis, etc., among which a large amount of cleaning wastewater will be generated in oxidation workshop and electrophoresis workshop, including: pre-treatment pickling water after degreasing and neutralization; alkaline wastewater generated during alkaline etching process; tin-containing wastewater generated in the process of coloring; pickling water after oxidizing and coloring wastewater after coloring; sealing holes and coating wastewater; and waste water after coloring. After oxidation and coloring; heavy metal wastewater from sealing and electrophoresis. This part of the profile cleaning water is discharged in the form of overflow to the cleaning tank, which is the main source of wastewater in aluminum profile factory.

In addition, there is potting wastewater, aluminum extrusion molds should be put into a high concentration of alkali solution for potting after use, the aluminum in the die cavity reaction corrosion, in the reaction process, will also produce a lot of wastewater.

How to deal with this type of industrial wastewater?

Aluminum profile wastewater in addition to containing a large number of aluminum ions, but also contains some zinc, nickel, copper and other metal ions, the composition is complex, acidic mostly, can not be discharged directly, need to be purified to the environmental protection emission standards, and polyacrylamide is a good helper to deal with these sewage.

Polyacrylamide (PAM) is a homopolymer of acrylamide or copolymerization with other monomers and polymers collectively, is a water-soluble polymer in one of the most widely used varieties, with good flocculation, adhesion, resistance and adsorption of adhesion, in the petroleum mining, water treatment, textiles, paper, mineral processing, medicine, agriculture and other industries with a wide range of applications, there is a "hundred industry additives "It has a wide range of applications in petroleum mining, water treatment, textile and paper, mineral processing, medicine, agriculture and other industries.

In industrial wastewater treatment, polyacrylamide can be used in conjunction with inorganic flocculants, with significant changes in water quality, in addition, can also be used as a coagulant aid in conjunction with other flocculants, greatly reducing the amount of flocculants, in addition, polyacrylamide formed flocs with high strength and good settling properties, thereby increasing the solid-liquid separation rate is conducive to sludge dewatering.

Fiona Chemical specializes in the supply of polyacrylamide and other types of water treatment additives, and provides continuous technical support and guidance to help aluminum enterprises to achieve optimal water treatment results.
