General Secretary Xi emphasized that 'lucid waters and lush mountains are golden mountains and silver mountains'. With the development of industry, the environment in which people live is getting worse and worse. Environmental protection is an obligation that each of us should fulfill.Many manufacturers choose polyaluminum chloride to treat sewage, river water, reservoir water, groundwater, urban sewage, industrial water purification, recovery of useful substances in various industrial wastewater and waste residues, polyaluminum chloride is also used in sugar refining, Pharmaceutical refining, cement quick-setting, cosmetic raw materials and other industries.With the wide application of polyaluminum chloride, many customers do not know how to choose polyaluminum chloride that meets the quality standards. In fact, there are three selection criteria for polyaluminum chloride: alumina content, basicity and pH value.1. Look at the alumina content. The alumina content is a measure of the active ingredients of the product. It has a certain relationship with the relative density of the solution. Generally speaking, the higher the relative density, the higher the alumina content.According to the content of aluminum oxide in the composition, it can generally be divided into 30

Polyferric sulfate has the advantages of hydrolysis rate, lower residual iron ions, lower price, proper PH value of 4-11, strong local turbidity, ability of phosphorus removal agent to remove heavy metals, COD, decolorization 2, removal Polyferric sulfate with a wide range of odor and degreasing effects is suitable for water treatment and papermaking, printing and dyeing, leather, metallurgy, food, petrochemical and chemical wastewater, sewage treatment and domestic sludge dehydration treatment.As a new type of iron salt water purification flocculant, polymerized ferric sulfate has a small change in the pH value and total alkalinity of the raw water after purification, and is less corrosive to the treatment equipment; it has the effect of purifying raw water with micro-pollution, algae, low temperature and low turbidity Significant, especially for the purification of high turbidity raw water; polyferric sulfate can replace polyaluminum chloride and other water purification agents in industrial wastewater treatment, and the wastewater treated with polyferric sulfate basically does not contain aluminum ions. It is of great significance in the treatment of some industrial wastewater.Thank you for your attention to Jiangsu Lanyao Water Purification

During the dissolution process of polyaluminum chloride, hydroxide ions release a large number of positive charges to absorb negatively charged ions in water, and the flocs form quickly and thickly, with high activity and fast precipitation, so as to achieve the purpose of decomposing and purifying sewage. The water purification effect is obvious.It is suitable for a lot of sewage, and can be used in sewage treatment in drinking water, domestic sewage, papermaking, chemical industry, electroplating, printing and dyeing, breeding, mineral processing, food, medicine, rivers, lakes and other industries, where it plays an important role.Application of polyaluminum chloride products: 1. Treatment of river water, lake water and groundwater; 2. Treatment of industrial water and industrial circulating water; 3. Treatment of urban domestic water and urban sewage; 4. Recovery of coal mine flushing wastewater and porcelain industrial wastewater ; 5. Printing factories, printing and dyeing factories, leather factories, meat processing factories, pharmaceutical factories, paper mills, coal washing, metallurgy, mining areas, and treatment of fluorine-containing oil and heavy metal wastewater; 6. Industrial wastewater and waste residues of useful substances back
