Case 1: Large palm oil mill in Malaysia - dehydration by belt filter press

Problem: Sludge characteristics: initial moisture content 99.2%, high organic matter content (VSS/SS ≈ 70%), high viscosity, difficult to dehydrate.

PAM solution:

Model: Special high cationic PAM

Ionic degree: 50%

Molecular weight: 12 million

Form: Granular

Dissolution time: <45 minutes

Effect:

PAM consumption per ton of dry sludge is reduced to 5.5kg (reduced by about 31%).

The moisture content of the mud cake is stabilized at 78-80% (significantly reduced).

The clarity of the filtrate is improved (SS < 200mg/L).

The belt filter press runs more smoothly and the filter cloth is less blocked.

Economic benefits: Annual PAM cost savings of approximately US$30,000, while reducing the costs for sludge transportation and disposal.
