Product Description:
Drinking Water Grade Polyaluminum Chloride (PAC) is a light yellow powdery inorganic polymer coagulant designed specifically for drinking water treatment. It meets national drinking water hygiene standards, such as GB 15892-2020/2009. The production process involves using calcium aluminate powder, high-purity hydrochloric acid, and other raw materials. These are processed through high-temperature and high-pressure reactions or spray drying to ensure that the heavy metal content is extremely low. For example, indicators like arsenic, lead, cadmium are far below the national standard limit.
This PAC is suitable for scenarios with strict requirements on water quality safety. Its formulation has been engineered to address the demands of drinking water treatment and it complies with recognized regulations to guarantee the safety and purity of the treated water.
Features:
Technical Characteristics
High purity and safety: Aluminum oxide (Al 2 O 3 ) content ≥ 29.5%, salinity 40-90%, heavy metal indicators strictly comply with drinking water standards (such as arsenic ≤ 0.0002%, lead ≤ 0.001%).
Physical properties: Light yellow powder, uniform and fine particles, easily soluble in water, fast dissolution rate, forming large and dense flocs, high settling efficiency.
Environmental protection and economy: The dosage is only 1/2-1/3 of traditional coagulants (such as aluminum sulfate), reducing processing costs; Low corrosiveness to equipment, suitable for a wide pH range (3.5-5.0).
Stability: After being prepared into a 10% aqueous solution, it can be stored stably for 30 days and can adapt to different water quality conditions (including low temperature and low turbidity water).
Production Process and Packaging
Adopt spray drying technology to ensure product uniformity and low insoluble matter (≤ 0.1%).
Packaging: 25kg double-layer bag (inner plastic film+outer woven bag), stored in a dry, cool place to avoid moisture or contact with corrosive substances.
Applications:
Urban waterworks and rural centralized water supply systems remove turbidity, heavy metals (such as arsenic and lead), fluoride, and microorganisms to ensure that water quality meets the "Sanitary Standards for Drinking Water".
Deep purification of industrial circulating water pretreatment and recycled water after sewage treatment.
Efficient treatment of high fluoride water, heavy metal containing wastewater, and low-temperature low turbidity water.
