Poly Aluminium Chloride Coagulant CAS 1327-41-9 for Wastewater
Product Overview
Poly Aluminium Chloride Coagulant CAS 1327-41-9, also known as PAC powder or Polyaluminum Chloride powder, is an inorganic polymer coagulant widely used for wastewater treatment.
Wastewater from municipal and industrial sources often contains suspended solids, colloids, fine particles, organic matter, color and other impurities. These pollutants may remain stable in water and are difficult to remove by natural settling alone.
PAC coagulant helps destabilize these particles through chemical coagulation. After dosing and mixing, fine particles begin to gather into larger flocs. These flocs can then be removed by sedimentation, dissolved air flotation or filtration.
Bluwat supplies spray dried Poly Aluminium Chloride powder in different grades, including PAC-02 and PAC-031 for wastewater treatment applications, and PAC-01 for drinking water and high purity water treatment requirements.
What Is Poly Aluminium Chloride CAS 1327-41-9
Poly Aluminium Chloride CAS 1327-41-9 is an aluminum based inorganic polymer coagulant used in water and wastewater treatment.
In wastewater treatment, its main function is to support coagulation. PAC neutralizes the electrical charge of suspended particles and colloids, allowing them to combine and form larger flocs.
CAS 1327-41-9 is commonly used in technical documents, safety data sheets, product specifications and international trade records to identify Poly Aluminium Chloride.
Why Use PAC Coagulant for Wastewater
Wastewater quality can change greatly depending on the source. Municipal sewage, textile wastewater, paper mill wastewater, mining wastewater and food processing wastewater all contain different types of impurities.
PAC coagulant is widely used because it can handle many wastewater conditions. It helps reduce turbidity, suspended solids and colloidal impurities. In some wastewater systems, it can also support color reduction and organic matter removal when used together with other treatment chemicals.
PAC is often used before PAM flocculant. PAC starts the coagulation process, while PAM helps enlarge the formed flocs and improve settling speed.
This combination is widely used in wastewater treatment plants, industrial clarification systems, DAF units and sedimentation tanks.
Key Advantages
PAC coagulant helps destabilize suspended solids, colloids and fine particles in wastewater, supporting efficient solid liquid separation.
PAC can reduce turbidity and improve the clarity of treated wastewater.
By forming larger flocs, PAC helps remove TSS from sewage and industrial wastewater.
Under proper dosing and mixing conditions, PAC supports quick micro floc formation and improves clarification efficiency.
PAC can be used before PAM flocculant to improve floc size, settling speed and sludge separation.
PAC is suitable for municipal wastewater, industrial wastewater, textile wastewater, paper mill wastewater, mining wastewater, coal washing wastewater and food processing wastewater.
Bluwat supplies PAC-02 and PAC-031 yellow powder grades for wastewater treatment, with different basicity and insoluble matter ranges for different cost and performance needs.
Bluwat provides PAC powder from factory production, with 25 kg bag packaging, stable quality and export service.
Recommended Grades for Wastewater
For most wastewater treatment applications, PAC-02 and PAC-031 are commonly selected according to wastewater quality, treatment target and operating cost.
Typical Wastewater Applications
PAC coagulant can be used in sewage treatment plants to improve coagulation, suspended solids removal, phosphorus removal support and effluent clarity.
PAC powder is widely used for industrial wastewater clarification. It helps remove suspended solids, colloids, fine particles and organic impurities.
Textile and dyeing wastewater often contains color, turbidity and organic pollutants. PAC can be used with water decoloring agent and PAM flocculant to improve treatment performance.
PAC helps remove fibers, fillers and suspended solids from paper mill wastewater, supporting clearer effluent and better sludge separation.
Mining wastewater contains fine mineral particles and suspended solids. PAC helps these particles form larger flocs for easier settling.
PAC can improve solid liquid separation in coal washing wastewater and support water recycling.
PAC supports pretreatment of food processing wastewater by reducing suspended solids and improving clarification.
For chemical wastewater with colloids and mixed impurities, PAC can improve coagulation before further treatment steps.
How PAC Works in Wastewater Treatment
PAC powder is usually dissolved in clean water before dosing.
After the PAC solution is added into wastewater, it disperses quickly under rapid mixing. PAC contacts suspended solids, colloids and fine particles, then neutralizes their surface charge.
Once the particles lose stability, they begin to form micro flocs. During slow mixing, these 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 separated from water by sedimentation, DAF or filtration.
Suggested Dosing Process
A common wastewater treatment process using PAC coagulant includes the following steps.
First, prepare PAC powder solution with clean water.
Second, dose PAC solution into 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 when larger flocs and faster settling are needed.
Finally, separate the flocs through sedimentation, dissolved air flotation or filtration.
The actual dosage should be determined by jar testing. Wastewater type, pH, turbidity, suspended solids, color, organic content and treatment target can all affect the best dosage.
PAC and PAM Combination
PAC and PAM are commonly used together in wastewater treatment.
PAC is the coagulant. It destabilizes suspended particles and forms micro flocs.
PAM is the flocculant. It bridges micro flocs into larger flocs and improves settling performance.
The recommended dosing order is PAC first and PAM second.
For wastewater with high color or stable dissolved pollutants, a water decoloring agent may be added before PAC depending on the wastewater condition.
