Cationic polyacrylamide(PAM) for water treatment
Cationic polyacrylamide, is a white powder water -soluble polymer which is copolymerized by cationic monomer and acrylamide. It has the function of decolorizing, adsorbing, turbid eliminating and bonding. It generate a good flocculation and can decrease the resistance between liquids.

Synthetic Polyelectrolytes Based on Acrylamide and Their
Synthetic Polyelectrolytes Based on Acrylamide and Their Application as a Flocculent in the Treatment of Palm Oil Mill as indicators. It was found that varying in the molecular weight of the cationic polyacrylamide from 20X10 3 to 1.5X10 6 g The optimum coagulant dosages were found to be dependent on the strength of the wastewater

Unveiling the mechanisms of how cationic polyacrylamide
Cationic polyacrylamide, a flocculation powder widely used in wastewater pretreatment and sludge dewatering, was highly accumulated in waste activated sludge. However, its effect on short-chain fatty acids (SCFAs) accumulation from anaerobic fermentation of waste activated sludge has not been investigated.

Effect of Cationic Polyacrylamide Adsorption Kinetics
The effect of polymer adsorption kinetics and ionic strength on the dynamics of particle flocculation was quantified using a model system consisting of precipitated calcium carbonate (PCC) and cationic polyacrylamide (CPAM) at a low shear rate. All early flocculations detectable by a photodispersion analyzer (PDA) happened in nonequilibrium polymer adsorption regimes.

Biomass Modification Using Cationic Surfactant
Adsorption based on natural fibre seems to widely used for oily wastewater recovery due to its low cost, simplicity, feasibility, easy handling, and effectiveness. However, oil sorbent based on natural fibre without modification has low adsorption capacity and selectivity. Thus, this paper proposes chemical modification of sago hampas to improve its adsorbent efficiency for the removal of palm

Pollutants analysis during conventional palm oil mill
The conventional palm oil mill effluent (POME) ponding system is unable to fully decolourise the effluent which is aesthetically important. Several parameters, such as low molecular mass coloured compounds (LMMCC), lignin-tannin, ammonia nitrogen (NH 3-N) and chemical oxygen demand (COD) in the cooling pond, are much higher than for the fresh raw POME.

Palm Oil Mill Biogas Producing Process Effluent Treatment
Although biological is the cheapest treatment for palm oil mill biogas producing process effluent, the recalcitrant compounds are the major hindrance for successful biological treatment. Therefore, pre-treatment should be investigated deeply and will be a major challenge in the future.
