PAC Powder Chemical Coagulant for Water Clarification
Product Overview
PAC Powder Chemical Coagulant, also known as Polyaluminum Chloride Powder or Poly Aluminium Chloride Powder, is an inorganic polymer coagulant widely used for water clarification.
In many water treatment systems, suspended solids, colloidal particles, clay, organic matter and fine impurities can make water cloudy. These particles are often too small to settle naturally. PAC powder helps destabilize these impurities through chemical coagulation and allows them to gather into larger flocs.
Once larger flocs are formed, they can be removed through clarification processes such as sedimentation, dissolved air flotation or filtration. This improves water clarity and supports more stable operation of downstream treatment units.
Bluwat supplies spray dried PAC powder in different grades, including PAC-01, PAC-02 and PAC-031, for drinking water clarification, municipal wastewater treatment and industrial wastewater clarification.
Why PAC Powder Is Used for Water Clarification
Water clarification is an important step in both water purification and wastewater treatment. When water contains fine particles and colloids, direct filtration or natural settling may not be enough.
PAC powder improves the clarification process by promoting coagulation and floc formation. It helps small and stable particles become larger, heavier and easier to separate from water.
For drinking water plants, PAC can help reduce turbidity before filtration and disinfection.
For wastewater treatment plants, PAC can help remove suspended solids, improve sedimentation and produce clearer treated effluent.
For industrial water systems, PAC can support pretreatment, reuse water treatment and process water clarification.
Key Advantages
Product Grades and Specifications
The suitable PAC grade should be selected according to water quality, turbidity level, pH value, treatment target and operating cost.
Main Applications
How PAC Powder Works in Water Clarification
PAC powder is usually dissolved in clean water before dosing.
After the PAC solution is added into water or wastewater, it disperses under rapid mixing and contacts suspended particles and colloids.
PAC neutralizes the surface charge of these particles. Once the particles lose stability, they begin to gather and 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 by sedimentation, dissolved air flotation or filtration. This process helps produce clearer water and improves treatment efficiency.
Suggested Dosing Process
A common water clarification process using PAC powder includes the following steps.
First, prepare PAC powder solution with clean water.
Second, dose PAC solution into water or wastewater under rapid mixing.
Third, allow PAC to fully contact suspended particles 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, flotation or filtration.
The actual dosage should be confirmed by jar testing. Water turbidity, pH, alkalinity, temperature, suspended solids and treatment target can all affect the best dosage.
PAC and PAM for Clarification
PAC and PAM are commonly used together in water clarification systems.
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 settling or flotation performance.
The usual dosing sequence is PAC first and PAM second. This sequence is widely used in drinking water clarification, wastewater treatment, DAF systems and industrial water treatment plants.
For wastewater with strong color or stable dissolved pollutants, a water decoloring agent may be added before PAC depending on the water condition.
