PAC Powder Water Treatment Chemical for Turbidity Removal
Product Overview
PAC Powder, also known as Polyaluminum Chloride Powder or Poly Aluminium Chloride Powder, is a widely used coagulant chemical for turbidity removal in water treatment.
Turbidity is mainly caused by suspended solids, clay particles, organic matter, colloids, algae and other fine impurities in water. These particles are often very small and can remain stable in water for a long time. Without proper coagulation, they are difficult to remove by simple sedimentation or filtration.
PAC powder works by neutralizing the electrical charge of these particles. After the charge is destabilized, small particles begin to gather and form larger flocs. These flocs can then be removed through sedimentation, flotation or filtration.
Bluwat PAC powder is produced by spray drying technology and supplied in stable powder form. It is widely used in drinking water plants, municipal wastewater systems, industrial wastewater treatment plants and many water clarification processes.
Why Turbidity Removal Is Important
Turbidity directly affects water clarity and treatment efficiency. High turbidity water may contain fine solids, colloidal particles, organic matter and other impurities.
In drinking water treatment, turbidity removal is an important step before filtration and disinfection. If turbidity is not properly reduced, the filtration system may become overloaded and the final water quality may be unstable.
In wastewater treatment, turbidity removal helps reduce suspended solids and improves the appearance of treated effluent. It also supports better downstream treatment performance, especially in sedimentation tanks, DAF systems and filtration units.
PAC powder is a practical chemical solution for improving turbidity removal performance in different water treatment processes.
How PAC Powder Removes Turbidity
PAC powder is first dissolved in water and prepared as a dosing solution. After dosing into raw water or wastewater, PAC disperses quickly under rapid mixing.
During the coagulation stage, PAC Flask neutralizes the surface charge of suspended particles and colloids. This reduces particle stability and allows small particles to collide and combine.
During the flocculation stage, the particles form larger and stronger flocs. If PAM flocculant is added after PAC, the flocs can become bigger and settle faster.
Finally, the flocs can be separated from water by sedimentation, flotation or filtration. The result is clearer water and lower turbidity.
Key Advantages
PAC powder helps remove fine suspended particles and colloids from water, improving overall clarity and treatment performance.
PAC reacts quickly after dosing and supports rapid formation of micro flocs in water treatment systems.
Under proper mixing conditions, PAC helps create compact and visible flocs that are easier to settle or filter.
PAC powder can be used for drinking water, municipal wastewater, industrial wastewater, paper mill wastewater, textile wastewater, mining wastewater and other water clarification needs.
PAC is commonly used before PAM flocculant. PAC starts coagulation, while PAM helps enlarge flocs and improve sedimentation speed.
The powder form is convenient for storage, transport and export. It can be dissolved into a solution before dosing.
With suitable grade selection and dosage optimization, PAC powder can help improve turbidity removal while controlling treatment cost.
Recommended PAC Grades
Bluwat supplies different PAC powder grades for different water treatment needs.
The suitable grade should be selected according to water source, turbidity level, pH value, treatment target and customer requirements.
Application Areas
PAC powder is used to remove turbidity from river water, lake water, reservoir water and other raw water sources before filtration and disinfection.
PAC can help reduce turbidity and suspended solids in sewage treatment plants, improving sedimentation and effluent clarity.
PAC powder is widely applied in industrial wastewater clarification, especially where wastewater contains fine particles, colloids and suspended solids.
In textile wastewater treatment, PAC supports turbidity reduction and floc formation. It can be used together with water decoloring agent and PAM flocculant.
PAC helps remove fibers, fillers and suspended solids from paper mill wastewater, improving clarification and sludge separation.
PAC is used for solid liquid separation in mining wastewater and coal washing wastewater, helping reduce suspended solids and improve water recycling.
PAC can support turbidity reduction and suspended solids removal in food processing wastewater and organic wastewater treatment systems.
Suggested Dosing Process
A common PAC turbidity removal process 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 solids and colloids.
Fourth, adjust pH if necessary according to jar test results.
Fifth, add PAM flocculant if larger flocs and faster sedimentation are required.
Finally, separate the flocs by sedimentation, flotation or filtration.
Jar testing is recommended before full scale operation. The best PAC dosage depends on turbidity level, pH, water temperature, alkalinity, suspended solids and treatment goals.
PAC and PAM for Better Turbidity Removal
PAC and PAM are often used together in turbidity removal systems.
PAC is the coagulant. It destabilizes fine particles and starts floc formation.
PAM is the flocculant. It helps bridge small flocs into larger flocs and improves settling speed.
The usual dosing sequence is PAC first and PAM second. This sequence is widely used in wastewater treatment plants, industrial clarification systems and DAF processes.
Packaging and Storage
Bluwat PAC powder is packed in 25 kg bags with inner plastic bag and outer woven bag.
Store the product in a cool, dry and well ventilated warehouse. Keep away from moisture, direct sunlight and high temperature. Keep bags sealed when not in use.
Proper storage helps maintain stable solubility and coagulation performance.
