Influence of type and dose of coagulants on effectiveness ...

2020-8-28 · This study evaluated the influence of the type and dose of coagulants on the removal of 16 polycyclic aromatic hydrocarbons (PAHs) in the coagulation process. The effects of coagulant type and dose in reducing water turbidity, colour, and the total content of organic compounds were also assessed. The surface water samples had the turbidity of 9.3-11.2 NTU and colour of 25-35 mg/L.

Drinking Water Production by Coagulation and

2016-4-23 · Drinking water production with low-pressure hollow-fibre membranes is be-coming increasingly more widespread as replacement for conventional separa-tion technology. Upstream coagulation can mitigate fouling layer formation on membranes and allows removal of colloidal and soluble compounds smaller than the membrane pores.
