Product Description
Overview of PAC 30%
PAC 30% powder, or Poly Aluminum Chloride, is PAC containing 30% aluminum oxide Al2O3. PAC is a type of white or yellowish powder that can completely dissolve in water. It is a coagulant used to remove suspended particles, dissolved or undissolved organic substances, and heavy metals from water.
In the market, PAC 30% powder chemical has a lower cost than PAC 31%. PAC 30% is also called brown PAC, PAC Qiutao, and is mainly used in industrial wastewater treatment.

Here are the quality indicators for Poly Aluminum Chloride - PAC 30% powder
Applications of PAC 30% Chemical
Chemical PAC is a widely used and applied coagulant in various industries. PAC powder is mainly used in the field of water treatment, specifically:
Water treatment of urban sewage, feed water, or swimming pool water
- PAC can help clarify water by coagulation and flocculation of suspended particles in water, without impacting water quality.
- Removes organic compounds, bacteria, and viruses.
Water treatment of wastewater industries from textile dyeing, papermaking
PAC 30% has strong color absorption, separating water molecules and dyes to clarify water.
Water treatment of aquaculture (shrimp ponds, fish ponds...)
- PAC powder increases the dissolved oxygen content in water and reduces toxic gases such as NH3, NO2, and H2S.
- Use PAC to help inhibit algae formation so that shrimp can develop safely.
- PAC 30% increases the clarity of ponds, helping to improve shrimp’s ability to catch prey.
Process of Wastewater Treatment with PAC 30%
How to Use PAC 30% Powder in Water Treatment
The way of PAC 30% powder phase is simple to remember. Dilute PAC into a 5-10% solution with clean water and add it to the water source to be treated with the following dosages:
- The dosage for 1 m3 of river, pond, and lake water:
- For water with low turbidity: 1- 4g/m3 PAC
- For water with medium turbidity: 5 - 7g/m3 PAC
- For water with high turbidity: 7 - 10g/m3 PAC
- The dosage of wastewater treatment (making paper, textile, dyeing, food processing) from 20-200g/m3, depending on the suspended matter content and the wastewater characteristics.
Advantages of Poly Aluminium Chloride (PAC 30%)
The PAC 30% chemical is produced from the reaction between hydrochloric acid (HCl) and aluminum powder. Compared to aluminum sulfate and inorganic alum, PAC has several advantages in water treatment, specifically:
- Powdered PAC dissolves completely in water; even at low dosages, it has excellent coagulation and flocculation abilities.
- PAC 30% powder contains 30% Al2O3, which results in faster coagulation time for suspended solids. PAC has a 4-5 times higher coagulation efficiency than aluminum sulfate.
- Using PAC has little effect on changing the pH in water; there is no need to use lime or alkalis to treat the water’s pH.
- Regardless of the amount of PAC powder used in less or more, it does not make the water turbid.
- Using PAC will not produce SO42- in wastewater after treatment like aluminum alum.
- PAC 30% powder can remove dissolved and undissolved organic compounds or heavy metals, better than aluminum sulfate.
- PAC helps reduce the sludge volume after the treatment of water.
