Abstract

Synthetic solutions assimilating irrigated groundwater containing varying concentrations of humic acid (10 -40 mg/L) and saline (10-35 g/L) and metal agents (5 mg/L) , were processed through a ceramic microfiltration membrane (Sterilox Ltd.,0.5 μm). This was done with enrichment schemes using polyme...

Abstract: Synthetic solutions assimilating irrigated groundwater containing varying concentrations of humic acid (10 -40 mg/L) and saline (10-35 g/L) and metal agents (5 mg/L) , were processed through a ceramic microfiltration membrane (Sterilox Ltd.,0.5 μm). This was done with enrichment schemes using polymeric coagulants (PDADMAC) applied to enhance the removal of the above-mentioned pollutants. The study was conducted with the scope of investigating the feasibility of sequential and hybrid coagulation and microfiltration as a method of choice for drinking water treatment. Membrane microfiltration is easily scalable into various arrangements, allowing versatility in operation and enrichment treatments, with a relatively lower cost which other treatment practices do not allow. The highest humic acid removal, 91.11 % was achieved with hybrid coagulation.
