Application Areas of Polyaluminum Chloride with Different Contents

Polyaluminum chloride (PAC) is an important chemical agent widely applied in various fields. Its application areas are primarily determined by the content of its alumina (Al2O3). Below are the main application areas for different contents of Polyaluminum chloride.Let's learn about it  with the Polyaluminum Chloride manufacturer.

Applications of Polyaluminum chloride with Different Contents:

1. High-content Polyaluminum chloride (Al2O3 content ≥30%) Application areas: Suitable for the drinking water industry, including water treatment facilities for tap water plants, purified water plants, pharmaceutical factories, food processing plants, and other industries with high water quality requirements. Mechanism of action: Used as a flocculant and filter aid to remove suspended solids, organic matter, heavy metals, and other pollutants from water, ensuring the safety and hygiene of drinking water.

2. Medium-content Polyaluminum chloride (Al2O3 content ≈28%) Application areas: Suitable for industrial wastewater treatment, especially in industries with high turbidity such as oily wastewater, dyeing plants, paper mills, steel mills, coal washing plants, plastic plants, etc. Mechanism of action: Effectively reduces turbidity, promotes sludge sedimentation, and reduces subsequent treatment burdens. It also removes Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), and Suspended Solids (SS) from wastewater.

3. Low-content Polyaluminum chloride (Al2O3 content ≤26%) Application areas: Suitable for urban domestic sewage treatment, i.e., treating low-turbidity municipal wastewater. Mechanism of action: Through mechanisms such as adsorption charge neutralization, adsorption bridging, compression of the double electric layer, and entrapment of sediments, it destabilizes, aggregates, flocculates, coagulates, and precipitates fine suspended particles and colloidal ions in the water, achieving purification.

Other Application Areas of Polyaluminum chloride:

Pulp and Paper Industry: Used for sizing and retention/filtration aids in paper production to improve paper strength and brightness while reducing fiber loss. Textile Dyeing Industry: Treats wastewater with high chroma and organic pollutant content, removing color and pollutants through coagulation. Mining and Mineral Processing: Used for solid-liquid separation, improving ore dressing efficiency and metal recovery rates, and separating ore washing and gangue from water. Environmental Protection: Used for the removal of heavy metal ions, such as soil remediation and groundwater treatment. Petroleum Extraction: Used as a primary material for wastewater treatment, removing suspended solids in drilling mud and crude oil, and serving as a displacement agent, water shut-off adjuster, drilling fluid adjuster, and fracturing fluid additive. Food Processing: Used as a clarifying agent in the production of juices, beverages, etc., to remove turbidity. Chemical Industry: Used for acid-base neutralization and pH adjustment. Agricultural Irrigation: Used for the purification of irrigation water, reducing suspended solid content. Bioengineering and Pharmaceuticals: Used as a microbial control agent or carrier material. Cosmetics and Beauty Industry: Used as raw materials or additives.

In summary, Polyaluminum chloride plays an important role in water treatment and related fields due to its unique properties and wide range of applications. Different contents of Polyaluminum chloride are suitable for different application areas. Therefore, when selecting Polyaluminum chloride, it is necessary to choose based on specific water quality data and the scope of flocculant applicability, and decide on its use only after testing and trial application have shown good treatment results.
