Industry Background

Textile dyeing wastewater treatment systems generate large amounts of excess biological sludge during daily operations. Inefficient sludge dewatering can significantly increase operational costs and reduce wastewater treatment efficiency.

A textile customer in Southeast Asia contacted Bluwat Chemicals after experiencing unstable sludge dewatering performance in its filter press system.

The plant processed reactive dye wastewater with high suspended solids and fluctuating organic loading.

Main Operational Problems

• Sludge cake remained soft and sticky
• Excessive sludge generation
• Low dewatering efficiency
• High disposal and transportation costs
• Poor settling during sludge conditioning
• Inconsistent polymer performance

Traditional inorganic coagulants alone could not achieve satisfactory sludge separation.

Laboratory Evaluation

Bluwat Chemicals performed sludge conditioning tests using several grades of Blufloc polyacrylamide.

The selected cationic PAM grade featured:

• High molecular weight
• Optimized cationic charge
• Rapid dissolution performance
• Excellent bridging capability

The technical data sheet of Blufloc Polyacrylamide indicates strong application performance in sludge thickening, sludge dewatering, and industrial wastewater treatment.

Sludge Dewatering Process Optimization

The optimized process improved sludge structure and enhanced free water release.

Final Results

Benefits of Blufloc Polyacrylamide for Textile Wastewater

• Rapid flocculation
• Strong sludge bridging
• Excellent settling performance
• Improved sludge cake dryness
• Lower chemical consumption
• Better dewatering efficiency

These advantages help textile factories comply with environmental discharge requirements while lowering operating costs.
