High Efficiency PAC Powder Coagulant for Water Treatment Plants
Product Overview
High Efficiency PAC Powder Coagulant, also known as Polyaluminum Chloride Powder or Poly Aluminium Chloride Powder, is an inorganic polymer coagulant widely used in water treatment plants.
Water treatment plants need reliable chemical coagulation to remove turbidity, suspended solids, colloids and fine impurities from water. These particles are often too small to settle naturally and may affect sedimentation, filtration and final water clarity.
PAC powder helps destabilize these particles and allows them to form larger flocs. These flocs can then be removed by sedimentation, dissolved air flotation or filtration.
Bluwat supplies spray dried PAC powder in different grades for drinking water plants, sewage treatment plants, industrial wastewater treatment plants and water purification systems.
Why Water Treatment Plants Use PAC Powder
Water treatment plants often face changing water quality. Raw water turbidity, wastewater load, pH, suspended solids and organic matter may fluctuate because of weather, industrial discharge, seasonal changes or production activity.
PAC powder is widely used because it provides stable coagulation performance and strong adaptability. It can help treatment plants improve water clarity, reduce suspended solids and support downstream filtration or biological treatment.
For drinking water plants, PAC supports raw water clarification before filtration and disinfection.
For municipal wastewater treatment plants, PAC helps improve sewage clarification, phosphorus removal support and effluent clarity.
For industrial water treatment plants, PAC helps reduce turbidity, color, colloids and suspended solids in process water or wastewater.
Key Advantages
PAC powder provides strong charge neutralization and helps fine particles gather into larger flocs for easier removal.
After dosing and mixing, PAC can quickly react with suspended solids and colloids, supporting faster clarification.
PAC helps water treatment plants improve sedimentation, filtration pretreatment and effluent clarity under changing water quality conditions.
PAC powder can be used in drinking water plants, sewage treatment plants, industrial wastewater plants, DAF systems, clarifiers and filtration pretreatment systems.
PAC is commonly used before PAM flocculant. PAC starts coagulation, while PAM enlarges flocs and improves settling speed.
Bluwat supplies PAC-01, PAC-02 and PAC-031 grades to meet different water treatment plant requirements.
Spray dried PAC powder is easy to store, transport and prepare as a dosing solution for continuous plant operation.
Bluwat provides stable PAC powder quality, 25 kg bag packaging, export service and technical support for global water treatment customers.
Product Grades and Specifications
Different treatment plants can select suitable PAC grades according to raw water quality, wastewater type, treatment target and operating cost.
Application in Drinking Water Plants
In drinking water treatment plants, PAC powder is used for raw water clarification.
Raw water from rivers, lakes, reservoirs or surface water sources may contain turbidity, suspended solids, clay particles, algae and colloidal impurities. PAC helps these impurities form larger flocs before sedimentation and filtration.
PAC-01 white powder is commonly recommended for drinking water treatment applications that require higher purity and low insoluble matter.
Application in Municipal Wastewater Plants
In municipal wastewater treatment plants, PAC powder can be used for sewage clarification, suspended solids removal and phosphorus removal support.
It can be applied in primary treatment, tertiary treatment, DAF systems or emergency chemical treatment when influent quality changes.
PAC helps improve floc formation and supports clearer effluent, especially when wastewater contains fine particles and unstable colloids.
Application in Industrial Water Treatment Plants
Industrial water treatment plants often treat wastewater from textile, paper, mining, food processing, chemical and metallurgical industries.
PAC powder helps reduce turbidity, suspended solids, colloids and some organic impurities. It can also be used as a pretreatment chemical before biological treatment, filtration, reuse systems or discharge.
For many industrial wastewater applications, PAC-02 and PAC-031 are commonly selected because they offer practical performance and cost effectiveness.
How PAC Powder Works in Water Treatment Plants
PAC powder is usually dissolved in clean water before dosing.
After the prepared PAC solution is added into raw water or wastewater, it disperses under rapid mixing and contacts suspended particles and colloids.
PAC neutralizes the surface charge of these fine particles. Once the particles lose stability, they begin to form micro flocs.
During slow mixing, micro flocs grow into larger flocs. If PAM flocculant is added after PAC, the flocs can become larger, stronger and faster settling.
Finally, the formed flocs are removed through sedimentation, dissolved air flotation or filtration.
Suggested Dosing Process
A common PAC dosing process for water treatment plants includes the following steps.
First, prepare PAC powder solution with clean water.
Second, dose PAC solution into raw water or wastewater under rapid mixing.
Third, allow PAC to fully contact suspended solids and colloids.
Fourth, adjust pH if necessary according to jar test results.
Fifth, add PAM flocculant under slow mixing if larger flocs and faster sedimentation are required.
Finally, separate the flocs through sedimentation, DAF or filtration.
The actual dosage should be determined by jar testing. Water quality, pH, turbidity, suspended solids, temperature and treatment target can all affect the best dosage.
PAC and PAM Combination
PAC and PAM are often used together in water treatment plants.
PAC is the coagulant. It destabilizes fine particles and forms micro flocs.
PAM is the flocculant. It bridges micro flocs into larger flocs and improves sedimentation or flotation performance.
The recommended dosing sequence is PAC first and PAM second.
This combination is widely used in sewage treatment plants, industrial wastewater treatment plants, DAF systems and clarification processes.
