Shield Slurry

Polyacrylamide (PAM) is mainly used as a flocculant in the treatment of shield mud waste slurry to accelerate solid-liquid separation. Through charge neutralization and adsorption bridging, it allows the fine particles and suspended matter in the waste slurry to quickly condense into larger flocs, which are convenient for sedimentation or filtration separation, thereby effectively purifying the water quality. At the same time, PAM can also improve dehydration efficiency, reduce sludge volume, and reduce subsequent treatment costs. Its application not only improves the efficiency of waste slurry treatment, but also reduces environmental pollution, helping the environmental protection and sustainable development of shield construction.
