Aluminium chlorohydrate (ACH) is increasingly replacing conventional coagulants like alum in industrial and municipal water treatment. Here are key questions we often received from plant engineers:
🔹 Why is ACH preferred over alum?
ACH has higher basicity, works across a wider pH range, produces less sludge, and leaves lower residual aluminium — resulting in better clarification and lower operating costs.
🔹 Is ACH suitable for RO pretreatment?
Yes. ACH is ideal for RO pretreatment because it forms dense flocs, reduces aluminium carryover, and minimizes membrane fouling, extending RO membrane life.
🔹 Does ACH require pH correction?
In most cases, no. ACH performs effectively between pH 5–9, reducing or eliminating the need for lime or caustic dosing.
🔹 How does ACH reduce sludge volume?
ACH produces compact, easily dewatered sludge, lowering disposal costs and reducing load on sludge handling systems.
🔹 Is ACH safe to handle?
Yes. It is less corrosive than alum or ferric chloride, improving operator safety and protecting dosing equipment.
🔹 Which industries benefit most from ACH?
Power plants, RO/DM systems, food & beverage, pulp & paper, sugar and ethanol plants, cooling towers, boiler feedwater systems, and municipal water treatment.
🔹 How is the correct ACH dosage determined?
Through jar testing and site-specific optimization — critical for maximizing performance and minimizing chemical use.
