Usually, anionic polyacrylamide water purifier is used to treat sand washing wastewater. The treatment of sand washing wastewater is actually the separation of mud and water. The water obtained after separation is recycled and reused in the sand washing. Anions are commonly used to separate mud by flocculating sedimentation.

  Mineral processing wastewater is mainly from the dust removal water in the crushing process,ore washing wastewater, cooling water and so on. Mineral processing wastewater is characterized by large amount of water, high content of suspended solids and many kinds of harmful substances. The harmful substances are heavy metal ions and mineral processing agents. Heavy metal ions include copper, zinc, lead, nickel, barium, cadmium, arsenic and rare elements. The direct discharge of such waste water without treatment will have a damaging impact on the surrounding and downstream rivers, soil, farmland, wetlands and other areas, and ultimately endanger human health. Therefore, effective treatment and recycling of mineral processing wastewater is very important. Concentrator special polyacrylamide series products are water-soluble linear polymer synthesized with high degree of polymerization. It is completely soluble in water and can dissolve quickly due to its microscopic form. Different types of polypropylene have different active groups, can condense different suspended particles, easy filtration and separation. The series of products are almost insoluble in any organic solvent, but are heavily soluble in water. It is widely used in many industries in the fields of flocculation, viscosity, bonding, scale inhibition, stable colloid, drag reduction, film formation, gel, biological materials...

 Circuit board is an important part of electronic components, but the waste water generated in the production process of circuit board contains a lot of pollutants, including copper, chromium, nickel, zinc, acid base and so on. If the circuit board waste water is not treated effectively, it will cause serious environmental pollution. When natural water is polluted by acids, alkalis and heavy metals, the water quality will deteriorate, the microbial activities will be inhibited or stopped, the self-purification capacity of water will be reduced, and the crops will be harmed. Heavy metal ions are not degraded by microorganisms. They can be absorbed and accumulated in living organisms, causing great harm to the human body and other organisms. Therefore, it must be harmless treatment, in order to meet the corresponding emission standards. As a water treatment flocculant, polyacrylamide also plays an important role in circuit board wastewater. Circuit board complexing wastewater is mainly from acid/alkali etching production line and PTH production line. This type of wastewater typically has a pH of between 4 and 9. Wastewater not only contains complexing agents (the main complexing agent is ammonia < 50mg/L, formaldehyde, EDTA, etc.), and contains a large number of metal ions...

In the late period of petroleum exploration and development, drilling waste liquid is a special industrial waste water produced in the process of drilling operations, containing oil, heavy metal salt, refractory organic matter, sediment, bacteria and other toxic and harmful substances, with complexity, change, dispersion and other characteristics, it is black brown opaque colloid state, with strong pungent smell and putrid smell.

The role of polyacrylamide precipitator in pile shield mud is adsorption, bridging, net trapping and electric neutralization, the role of polyaluminum chloride is to produce strong electric neutralization reaction to colloids in water, adsorption bridging, etc. Some difficult mud even need to add lime calcium oxide for coagulation or dilution treatment.

Anionic polyacrylamide is used in mining wastewater. Polyacrylamide is an organic polymer flocculant. It is widely used in the field of sewage disposal.

Polyacrylamide is divided into four types: anionic, cationic, nonionic and zwitterionic. The parameter index in each polyacrylamide is also different, so its action basis and effect will be different. The charges in wastewater from different industries are also different, and different types of polyacrylamide are required to treat the effect. This is also the main reason why polyacrylamide needs to be selected.

　　Municipal wastewater is the wastewater produced by residents in their daily lives, such as toilet water after flushing, wastewater after cooking and washing dishes, bath water, etc. It mainly comes from residential buildings and public buildings, such as houses, institutions, schools, hospitals, stores, public places and toilets of industrial enterprises.   Polyacrylamide is also generally divided into water treatment and sludge treatment in the municipal wastewater industry. Earlier it was more often used in the latter part of sludge dewatering in domestic wastewater treatment plants, using cationic polyacrylamide, generally used in centrifuges, belt filter presses, plate and frame filter presses. With the tightening of national environmental protection policy, most areas of the country have to carry out the first-class A standard transformation, some municipal wastewater after biochemical treatment of water quality can not meet the standard discharge will need to increase the depth of treatment process, and then through a high-efficiency sedimentation tank to deal with.This process is mainly to add inorganic flocculants (polymeric aluminum chloride, aluminum sulfate, etc.) and anionic polyacrylamide together with flocculation and precipitation to reduce the index of harmful substances in the sewage, so that the sewage meets the discharge standards.   As for how to...

Detailed description of polymeric ferric sulphate for power plants: Polyferric sulphate for power plants can be adapted to different sewage water conditions. Various wastewaters, organic, inorganic, sewage, and complex sewage treatments in wastewater systems with variable pH changes. The technical advantages and economic advantages solve the shortcomings of large consumption and dehydration of industrial wastewater and small domestic sewage treatment plants, which reduces the large demand and operating cost of the enterprise, electroplating wastewater treatment, electroplating wastewater treatment and reuse of flocculant It is the most cost-effective, most potential, and highly applicable sewage treatment flocculant.
