SA Water at the Australian Water Quality Centre (AWQC)
Two of the most common water quality issues faced by water management companies are elevated levels of geosmin and MIB. These two chemicals, which are naturally occurring compounds with earthy or musty odours, are associated with algae blooms or other microorganisms in water sources.
Testing conducted by SA Water at the Australian Water Quality Centre (AWQC) demonstrated that Bygen’s sustainable powdered activated carbon (PAC) product could achieve up to 50% improved removal rates of geosmin and MIB compared to the current market leading coal based PAC.

This testing involved spiking of geosmin and MIB into test water at concentration between 130 - 150 ng/L, with PAC dosage rates between 10 and 40 mg/L applied. The contact time and PAC dose rates applied represent typical conditions observed in drinking water treatment. The results from this trial indicated that only 1200 kg of PAC would be required for a WTP flow rate of 10 ML/day with a 7 day PAC dose period. This demonstrates strong benefits for water treatment companies, who can achieve target MIB and geosmin reduction levels with reduced application of PAC in their water quality management systems through using Bygen’s activated carbon products.
