Why Use RIW-PAC Instead of Alum?
RIW-PAC can be considered as an alternative to alum in suitable water treatment and effluent treatment applications. It may offer advantages in coagulation, clarification, pH impact, and sludge handling depending on water quality and treatment conditions.
- Supports coagulation and clarification
- May require lower dosage compared with alum, depending on application
- Can help reduce sludge generation in suitable treatment processes
- Supports treatment of water and industrial effluent
- Consistent quality.
- Consistent product quality
- Can be considered where alum replacement is technically suitable

Frequently Asked Questions
What is Poly Aluminium Chloride used for?
Poly Aluminium Chloride, also known as PAC, is used as an inorganic coagulant in water treatment, wastewater treatment, ETP, coagulation, clarification, and turbidity reduction applications.
What is RIW-PAC?
RIW-PAC is a grade of Poly Aluminium Chloride used for water treatment and clarification applications. It supports coagulation and helps remove suspended matter and turbidity from water and effluent streams.
Is PAC better than alum?
PAC may offer advantages over alum in suitable treatment processes, such as lower dosage requirement, better clarification, and lower sludge generation. Actual performance depends on water quality, pH, dosage, and treatment conditions.
What is the difference between PAC and alum?
PAC and alum are both used as coagulants in water treatment. PAC is a polymeric inorganic coagulant, while alum is aluminium sulphate. PAC may have different dosage, pH impact, and clarification performance depending on treatment conditions.
Can PAC be used in ETP treatment?
Yes, PAC can be used in ETP and wastewater treatment applications where coagulation, clarification, and suspended solids removal are required. Suitability and dosage should be confirmed through jar testing or technical evaluation.
How should PAC dosage be decided?
PAC dosage should be decided based on water quality, turbidity, pH, suspended solids, treatment objective, and process conditions. Jar testing or lab testing is recommended before full-scale use.
What is the difference between RIW-PAC and RIP-PAC?
RIW-PAC and RIP-PAC are different PAC grades. Their suitability depends on treatment application, product specification, and technical requirements. The technical team should confirm the correct grade for drinking water, water treatment, wastewater, or ETP use.
