Comparison Of The Effect Of Two Support Materials On Copper Removal From Aqueous Solution In The Activated Sludge Process

Two support materials, microwave incinerated rice husk ash (MIRHA) and groundwater treatment plant sludge (GWTPS), were used as support materials for biomass in the removal of copper from aqueous solution during a continuous flow study.

Description
Summary:Two support materials, microwave incinerated rice husk ash (MIRHA) and groundwater treatment plant sludge (GWTPS), were used as support materials for biomass in the removal of copper from aqueous solution during a continuous flow study. A third reactor containing biomass alone without the addition of support material (RB) was used as a control to monitor the performance of the support materials. All reactors were given 15 days for the acclimatization of biomass. The reactors containing MIRHA and GWTPS were given an additional 10 days for acclimation after the addition of the support materials on day 15. All reactors were identically designed with a size of 8.5 L and operated at a flowrate of 7 L/d and SRT of 30 days across 8 different phases. The results have shown that MIRHA and GWTPS have the potential of improving biomass resistance to toxicity of heavy metals.
