Are organic polymers effective coagulants for municipal wastewater treatment?

Organic polymers are effective coagulants for municipal wastewater treatment. High MW synthetic organic coagulants effectively remove target pollutants. Organic polymers require a lower dose than metal salt coagulants. Semi-natural organic coagulants form readily settleable flocs. 1. Introduction

Can polyamine be used as a precipitation agent in municipal wastewater treatment?

Based on the results obtained, polyamine products with high MW and (very) high CDs have the potential to act as the sole precipitation agent in both primary and secondary stages of municipal wastewater treatment.

Can polyaluminium chloride and aluminum sulfate improve coagulation performance?

Using coagulants polyaluminium chloride and aluminum sulfate to optimize phosphorus and turbidity removal from secondary effluent Hydrolysis of polyaluminium chloride prior to coagulation: effects on coagulation behavior and implications for improving coagulation performance J.

Can OC be used as a precipitation agent in municipal wastewater treatment?

Use of OC as the sole precipitation agent in municipal wastewater treatment is rare, mostly due to their relatively high cost and their perceived inability to remove dissolved contaminants such as dissolved organic carbon (DOC) and phosphate P (PO4 -P).

Are turbidity and Tot-P different in secondary wastewater coagulants?

In the treatment of secondary wastewater samples, removal of turbidity and tot-P were found to differ substantially (Kruskal Wallis p = 0.012, 0.080 consecutively) among the coagulants while removal rates of BOD 7 and tot-N were not significantly different (Kruskal Wallis p = 0.120, 0.130 consecutively).
