Magnetic flocculation of algae-laden raw water and removal

In the current study, the magnetic flocculation performance of algae-laden raw water purification was investigated by using magnetic composite flocculant Fe3 O 4 /cationic polyacrylamide (CPAM). The Chlamydomonas sp., turbidity and UV 254 removal efficiency were evaluated at different Fe 3 O 4: CPAM mass ratios, dosages and pH values.

Coagulation flocculation has demonstrated that it is an effective method and TBP can be used as a substitute to classical coagulant agents in industrial wastewater treatment. TBP as a natural coagulant did not require any coagulation pH adjustment and allowed more than 60% and 96% of COD and colour removals from industrial wastewaters respectively.

Interference of the polyacrylamide coagulant in the fluorescence

Cationic polyacrylamide decreases the linear correlation between DOM and fluorescence, e.g., from 0.92 to 0.82 for C1 and from 0.84 to 0.79 for C2. The C3 component, a protein-like material, was the most affected.

Evaluation of newly developed reverse demulsifiers and cationic

For treating oily produced water (OPW) originating from the steam-assisted gravity drainage (SAGD) process, we prepared three water-soluble and cationic reverse demulsifiers - poly aluminium chloride and quaternary ammonium salt (PAC-QAS), polyamine (PA), and polyamine and poly aluminium chloride (PA-PAC).

Research on a new cationic polyacrylamide (CPAM) with a cationic

Abstract Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge.
