Drinking Water Treatment Grade Coagulant Light Yellow PAC Polyaluminium Chloride

As a highly efficient water purifier, drinking water grade polyaluminium chloride has higher requirements than industrial grade polyaluminium chloride. With its high purity and low toxicity, it has become the first choice for drinking water treatment and industrial water treatment.

1. The difference between drinking grade PAC and industrial grade PAC

Drinking water grade polyaluminium chloride needs to strictly control the content of heavy metals (arsenic, lead, cadmium, etc.), for example, the arsenic content is ≤ 0.00001ppm, which is far below the industrial standard. At the same time, its production process needs to remove residual impurities to ensure no secondary pollution risk.

2. National standard requirements for drinking-grade PAC

Purity: Aluminum oxide (Al2O3) content ≥ 29% (solid).

Basicity: Drinking water grade PAC is usually controlled at around 45-80%, which meets the needs of low turbidity water treatment.

Limit of harmful substances: Lead ≤ 0.00001%, heavy metals such as mercury and chromium must be below trace levels.

1. Efficient flocculation and sedimentation

By releasing highly charged cations, it quickly adsorbs suspended solids to form large flocs, which is especially suitable for high turbidity water purification, and the sedimentation rate is more than 30% faster than traditional agents.

2. Removal of color and odor

It has strong adsorption capacity for organic pollutants and soluble substances, and significantly improves the taste and transparency of water quality.

3. Wide adaptability

The pH value has a wide range of application (3.5-5.0), which can cope with different water source conditions, such as acidic or neutral water bodies.

4. Safety and environmental protection

The aluminum residue strictly meets the drinking water standards to avoid long-term intake of health risks.

• Water plant: Treat surface water or groundwater to reduce turbidity to ≤1NTU.
• Rural drinking water project: Solve the problem of water source pollution, low cost and easy operation.
• Emergency water purification: Quickly purify water sources after natural disasters to ensure drinking water safety.
