Poly Aluminium Chloride (PAC) is an advanced inorganic polymeric water treatment agent. It exhibits strong flocculating and adsorbing properties, making it effective in removing suspended particles, colloids, and some dissolved substances from water. PAC is widely used in drinking water, industrial water purification, and sewage treatment due to its high efficiency and ease of use.
white polyaluminium chloride produced by Xinhuan Water Treatment is made by high-pressure reaction of aluminium hydroxide powder and high-purity hydrochloric acid.
Its solid is white powder, and its 10% aqueous solution is a colourless transparent liquid.
It is easily soluble in water, and during the hydrolysis process, it is accompanied by electrochemical, condensation, adsorption and other processes, and has a strong bridging adsorption effect.
It is widely used in papermaking, medicine, daily chemicals, cosmetic additives and drinking water purification.
Polyferric Sulfate(PFS), also known as Polymeric Ferric Sulfate and Polyferric Sulphate, is an iron-based inorganic polymer coagulant. The solid is light yellow powder and is easily soluble in water; the aqueous solution is a reddish brown transparent solution. It has the advantages of high hygroscopicity, extremely high flocculation ability, fast sedimentation rate and wide application range.
Poly ferric sulfate has stable performance, excellent water purification effect and does not contain heavy metal ions and other harmful substances. It has the functions of decolourisation, deodorisation, deodorisation, odour removal, removal of heavy metal ions, radioactive substances and carcinogenic substances in water. The removal rate of COD, BOD and chromaticity is above 90%. It has good purification effect on low temperature, low turbidity and high turbidity raw water.
Poly ferric sulphate can also be used as phosphorus remover. Compared with other inorganic flocculants, the treatment cost can be reduced by 20% - 50%. Widely used in thermal power plants, coking plants, paper mills, printing and dyeing plants, electroplating plants, chemical plants and other heavily polluted wastewater treatment (because of its pH range is wider than that of polymeric aluminium chloride, suitable for pH value fluctuation of water quality).
Drinking water grade polymeric aluminium chloride produced by Xinhuan Water Treatment is produced by spray drying process (powder) and roller drying type (granule).
It is produced with high quality raw materials such as aluminium hydroxide, hydrochloric acid and calcium aluminate powder. The technical standard is in line with the national GB15892-2020 standard, and the appearance of the product is yellow powder or granule.
The product can remove bacteria, deodorant, fluorine, aluminium, chromium, oil, turbidity, heavy metal salts, in addition to radioactive pollutants, in the process of purifying a variety of water sources have a wide range of uses.
It is suitable for drinking water, city water supply and drainage, circulating cooling water and paper making sizing precipitant, sugar decolouring and clarifying agent.
Polyaluminium chloride(PAC), as a polymer water purification material, is an inorganic polymer coagulant, referred to as PAC, polyaluminium, polyaluminum chloride, aluminum polychloride, Polymeric aluminum chloride.

Industrial-grade PAC adopts the most advanced spray drying production process and is made by polymerization of high-quality raw materials.
The product has the advantages of flocculation and fast precipitation: good stability, wide adaptability to water, fast hydrolysis, strong adsorption capacity, formation of alumina flowers, dense precipitation, low effluent turbidity, good dehydration performance, etc.
As the most effective water treatment chemicals, widely used in water treatment and drinking water, industrial water and sewage, wastewater treatment and other fields.

What is the Difference Between SAW Grade Material and Optical Grade Material?
Optical grade materials are materials with low strain and no impurities, they are grown from the best raw materials at a relatively slow growth rate, and are often used in optical applications where the highest quality is required. Optical grade wafers are widely used in optical devices and require excellent optical performance.
SAW grade materials are primarily used in non-optical applications, and their growth raw materials rank second only to optical grade growth raw materials. The growth rate of this material is faster than that of optical grade material, which benefits mass production and cost-effectiveness.
In general, these grades of wafers vary in material quality and use. Optical grade wafers are considered to be of the highest quality, while SAW grade wafers are relatively lower in price. The selection of the appropriate wafer grade is crucial, depending on the specific application and material quality requirements.
