Kerry Rowe’s Research Team Finds pH 7 Pore Water Can be More Aggressive than pH < 5 or pH > 9 to HDPE Geomembranes
PW-7 was the most aggressive solution in terms of degradation of mechanical properties of the HDPEs, while PW-9.5 was the most aggressive for antioxidant depletion for all three GMBs. The relative performance of the three GMBs in different tailings pore waters could not be predicted from the GMBs’ initial properties or the solutions’ chemistry. Overall, results highlight the importance of conducting immersion tests for applications involving complex chemical environments.

The operation of these bags is based on gravity, and requires no mechanical units. The system is modular in operation, therefore making the bags potentially suitable for decentralised faecal sludge treatment. Geobags are claimed to remove TSS by >99 per cent after solid-liquid separation; TS of up to 25-30 per cent remains in the dewatered sludge. The major disadvantage of geobags is its non-reusability. These bags have to be usually discarded once the entire volume is occupied by solids.
