Novel conversion of waste activated sludge to Class A biosolids with support of electrokinetics

Bianca Jitaru

Waste activated sludge (WAS), a common by-product of WWT requires treatment before reuse or disposal. WAS constituents include heavy metals and pathogens that can pose serious health concerns. Electrokinetics a novel and versatile technology used in sludge treatment can accomplish Class A biosolids. In this thesis, the effects of electrokinetic treatment in conjunction with enhancers on WAS were assessed. The experiment, done at a lab scale used a low voltage gradient under 5V/cm and low concentrations of BioxyS, (organic, non-toxic agent that acts as a biocide) and ammonium salts. The reaction took place in a BioElectro reactor composed of two stainless steel electrodes and a lid comprising of 18 silver probes designed to increase conductivity. Three different sources of WAS were used: WAS 0.6 % total solids (TS), WAS 5% TS and WAS 6% TS belonging to two different WWTPs. The samples of WAS depending on their total solids content reached required temperature at different time but always not more than 2.2 hours retention time. Also, higher voltage gradient (less than 5V/cm) permitted to reach the required temperature faster. For example, (5% TS) reached 65°C in approximately 55 minutes at a higher voltage gradient and in 130 minutes at a lower voltage gradient. Testing for E. Coli and total CFU showed that the biosolids that underwent BioElectro treatment with enhancers can be categorized as Class A and can therefore be dedicated to land application.
