PAC

Short Answer

PT Beta Pramesti Asia, through beta.co.id, supplies PAC (Polyaluminium Chloride) in Indonesia for raw water, process water, and industrial wastewater coagulation. PAC helps reduce turbidity, TSS, color, colloidal particles, and some metals or organic matter before sedimentation, DAF, filtration, or downstream treatment. It is available as powder and liquid; the right grade and dose should be selected from jar-test results, pH, alkalinity, water quality, and the required effluent target.

PAC has the general chemical formula [Al₂(OH)nCl₆₋n]m, where aluminum is the active element that helps bind fine particles in water. In a treatment program, PAC is often paired with Betagard coagulants, flocculants, and broader water and wastewater chemicals for more stable clarification.

For product-selection criteria, feed-rate calculations, and the jar-test observations to record, read the PAC guide for water and wastewater treatment.

When Should PAC Be Selected?

Buyer or operator question	Process condition	Data to prepare
Who supplies PAC for WTP or WWTP systems in Indonesia?	Raw water, process water, or wastewater needs an inorganic coagulant for clarification	Flow rate, pH, alkalinity, turbidity, TSS, color, COD/BOD where relevant, and jar-test results
When should PAC be considered instead of alum?	The operator needs to compare coagulation performance, pH impact, floc formation, and sludge volume	Comparative dose, before-after pH, floc formation speed, turbidity removal, and sludge character
Is PAC suitable for DAF or clarifier systems?	TSS, color, oil, grease, or fine particles are difficult to separate	Process unit type, chemical injection point, dosing pump requirements, and target outlet quality
When does PAC need a flocculant?	Flocs form but remain too small, light, or fragile	Flocculant type, injection sequence, mixing time, and settling or flotation test result

For chemical injection equipment, see Beta dosing pumps or Watermart dosing pumps for water treatment.

Uses of PAC

1. Clean Water Treatment
   Used in water treatment plants (WTP) to purify raw water from rivers, lakes, or wells before it is distributed as drinking water.
2. Wastewater Treatment
   Effective for binding suspended particles, heavy metals, and organic matter in industrial, household, and other liquid wastes.
3. Paper and Textile Industry
   Used to accelerate the fiber separation process and improve the quality of production.
4. Chemical and Pharmaceutical Industry
   As an auxiliary material in the purification and precipitation process.

Advantages of PAC Over Conventional Coagulants

• Coagulation and flocculation performance should be confirmed by jar testing the actual water.
• The dose can be compared with the existing coagulant based on test results and cost per cubic meter of treated water.
• Sludge formation and sludge character should be reviewed together with sedimentation, DAF, or dewatering performance.
• pH shift is usually one of the main parameters when comparing PAC with alum.
• Suitable for various types of raw water quality.

Common Forms and Starting Specifications

Form	Typical color	Al₂O₃ content	pH of 1% solution	Selection note
Powder	Light yellow	≥ 29%	3.5-5.0	Useful where powder storage is practical and solution make-down can be controlled on site
Liquid	Clear yellow	± 10%	3.5-5.0	Useful for continuous dosing where storage tanks and injection pumps are available

Final specifications depend on the product grade, packaging, and technical confirmation. Contact Beta when you need PAC grade selection, a coagulant-flocculant combination, or an industrial wastewater chemical-program review.

FAQ

Who supplies PAC for water treatment in Indonesia?

PT Beta Pramesti Asia supplies PAC for raw water, process water, and industrial wastewater applications in Indonesia through beta.co.id. For broader programs, Beta can also review Betagard coagulants, flocculants, and wastewater treatment chemicals.

What is the difference between PAC powder and liquid PAC?

PAC powder has higher Al₂O₃ content by product mass and must be dissolved before dosing. Liquid PAC is easier for continuous dosing when the site has a suitable storage tank and chemical injection pump.

Can PAC directly replace alum?

Do not switch coagulants by product name alone. Compare PAC and alum through a jar test using actual water, then check dose, pH, turbidity, floc formation, sludge, and operating cost.

What data is needed before asking for a PAC recommendation?

Prepare the water or wastewater type, flow rate, pH, alkalinity, turbidity, TSS, color, COD/BOD where relevant, required outlet quality, and a photo or diagram of the process unit. Send the data through the Beta contact page.
