PAC Coagulant Powder for Industrial Water Treatment Chemicals
Product Overview
PAC Coagulant Powder, also known as Polyaluminum Chloride Powder or Poly Aluminium Chloride Powder, is an inorganic polymer coagulant widely used in industrial water treatment.
Industrial water systems often need stable clarification before further use, discharge or recycling. Water may contain suspended solids, colloidal particles, fine clay, organic impurities, color bodies and process residues. These impurities can affect production efficiency, equipment operation, filtration performance and final effluent quality.
PAC powder helps remove these impurities through chemical coagulation. After dosing into water, PAC neutralizes the surface charge of fine particles and colloids. These particles then gather into larger flocs, which can be separated by sedimentation, flotation or filtration.
Bluwat supplies spray dried PAC powder in different grades for industrial water treatment, municipal wastewater treatment and drinking water purification.
Why PAC Is Used in Industrial Water Treatment
Industrial water treatment covers many different applications, including process water clarification, cooling water pretreatment, wastewater pretreatment, reuse water treatment and effluent polishing.
In these systems, water quality may change frequently due to production process, raw materials, operating conditions and wastewater composition. PAC coagulant powder provides flexible and stable treatment performance for different industrial water qualities.
PAC can help reduce turbidity, suspended solids and colloidal impurities before filtration or biological treatment. It can also be used together with PAM flocculant to improve floc size, sedimentation speed and sludge separation.
For industrial users, PAC powder is a practical water treatment chemical because it is easy to store, easy to dissolve and suitable for continuous dosing operation.
Key Advantages
PAC powder provides strong charge neutralization and helps destabilize suspended solids, colloids and fine particles in industrial water systems.
PAC helps reduce water turbidity and improves the visual clarity of treated water.
After proper dosing and mixing, PAC helps form larger flocs that are easier to settle, float or filter.
PAC can be used in paper, textile, mining, coal washing, food processing, chemical, metallurgical and general industrial water treatment systems.
PAC is often used before PAM flocculant. PAC starts coagulation, while PAM enlarges flocs and improves sedimentation performance.
Bluwat supplies PAC-01, PAC-02 and PAC-031 grades for different industrial water treatment requirements.
Spray dried PAC powder is easy to transport, store and prepare as a dosing solution.
Bluwat provides stable PAC powder quality, 25 kg bag packaging, export supply and technical support for industrial customers.
Product Grades and Specifications
The suitable PAC grade should be selected according to water quality, turbidity level, pH, treatment target and operating cost.
Industrial Water Treatment Applications
PAC powder can be used to clarify process water by removing suspended solids, colloids and fine impurities before production use.
PAC helps reduce turbidity, suspended solids and colloidal particles before biological treatment, filtration or discharge.
PAC can support the removal of suspended solids and fine particles before water enters cooling water systems.
For industrial water reuse systems, PAC can be used as a pretreatment chemical before filtration, membrane treatment or advanced purification.
PAC helps remove fibers, fillers and suspended solids from paper mill water and wastewater, supporting clarification and sludge separation.
In textile and dyeing wastewater treatment, PAC can help improve coagulation, turbidity reduction and floc formation.
PAC supports solid liquid separation in mining water and coal washing water by aggregating fine mineral particles and suspended solids.
PAC can be used in food processing wastewater pretreatment to reduce suspended solids and improve clarification efficiency.
PAC helps destabilize colloids and mixed impurities in chemical wastewater, improving coagulation before further treatment.
How PAC Powder Works
PAC powder is usually dissolved in clean water before dosing.
After the prepared PAC solution is added to industrial water or wastewater, it disperses quickly under rapid mixing. PAC contacts suspended particles, colloids and other impurities and neutralizes their surface charge.
Once the particles lose stability, they begin to combine and form micro flocs. During slow mixing, these micro flocs grow into larger flocs.
If stronger floc formation is required, PAM flocculant can be added after PAC. PAM helps bridge the small flocs into larger and stronger flocs, improving sedimentation or flotation performance.
Finally, the flocs are removed by sedimentation, DAF or filtration.
Suggested Dosing Process
A common industrial water treatment process using PAC powder includes the following steps.
First, test the water quality, including turbidity, pH, suspended solids, color and treatment target.
Second, dissolve PAC powder in clean water to prepare a dosing solution.
Third, add PAC solution into the water under rapid mixing.
Fourth, allow PAC to fully contact suspended particles and colloids.
Fifth, adjust pH if necessary according to jar test results.
Sixth, add PAM flocculant under slow mixing if larger flocs are needed.
Finally, separate the flocs through sedimentation, flotation or filtration.
Jar testing is recommended before full scale operation. The actual dosage depends on water quality, process condition, treatment goal and selected PAC grade.
PAC and PAM Combination for Industrial Water
PAC and PAM are commonly used together in industrial water treatment.
PAC is the coagulant. It neutralizes particle charge and starts micro floc formation.
PAM is the flocculant. It bridges small flocs into larger flocs and improves settling speed.
The usual dosing order is PAC first and PAM second. This sequence is widely used in industrial wastewater treatment, DAF systems, clarifiers and sludge separation processes.
For water with high color or stable dissolved organic pollutants, a water decoloring agent may be used before PAC depending on the wastewater condition.
Packaging and Storage
Bluwat PAC Coagulant Powder is packed in 25 kg bags with inner plastic bag and outer woven bag.
