Product Description:
Introduction
Drinking Water Grade Polyaluminum Chloride (PAC) is a light yellow powdery inorganic polymer coagulant specifically tailored for the treatment of drinking water. This product complies with national drinking water hygiene standards, such as GB 15892-2020/2009.
Product Composition
It is produced using calcium aluminate powder, high-purity hydrochloric acid, and additional raw materials. These ingredients undergo a high-temperature and high-pressure reaction or spray drying process to guarantee an extremely low heavy metal content. Parameters such as arsenic, lead, cadmium, and other indicators remain well below the national standard limits.
Application
Drinking Water Grade PAC is well-suited for environments that demand stringent requirements for water quality safety. It is an ideal choice for scenarios where water quality is of utmost importance.
Features:
Technical Characteristics
High purity and safety: Aluminum oxide (Al₂O₃) 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:
Among the methods employed by urban waterworks and rural centralized water supply systems are the removal of turbidity, heavy metals like arsenic and lead, fluoride, and microorganisms. This is done to guarantee that the quality of water meets the standards set for drinking water sanitation.
The process involves the thorough purification of industrial circulating water before and after sewage treatment, in order to ensure efficiency and the safe reuse of water resources.
Specialized treatments are utilized for different types of water, including the efficient treatment of high-fluoride water, wastewater containing heavy metals, and low-temperature, low-turbidity water. These specific treatments are crucial in addressing unique water quality challenges.
