Optimisation of nutrient removal, membrane fouling and sludge dewatering in hybrid coagulation/submerged membrane bioreactor treatment of wastewaters. Submerged membrane bioreactor technology for the treatment of wastewaters is now a competitive technology with small footprint and generally high quality of treated effluent. Despite this, challenges remain in ensuring low effluent nutrient concentrations, minimal membrane fouling and acceptable excess sludge dewaterability.

Submerged membrane bioreactor technology for the treatment of wastewaters is now a competitive technology with small footprint and generally high quality of treated effluent. Despite this, challenges remain in ensuring low effluent nutrient concentrations, minimal membrane fouling and acceptable excess sludge dewaterability. Addition of iron or aluminium-based coagulant chemicals can assist but many uncertainties with regard to choice of chemical, optimal dosing arrangements and membrane bioreactor operating conditions remain. Experimental and computational studies targeted at improving understanding and optimising performance will be undertaken through collaborative studies by the UNSW and Tsinghua University (Beijing) research team.Read moreRead less

Water resource is limited and has been continuously decreasing. The idea of recycling and reusing of wastewater has been adopted for irrigation, industry and other non-potable uses. In Australia, wastewater reuse is now considered a key strategy for conserving water at national, state and local level. In this study, the proposed treatment unit is to produce a superior effluent quality for water reuse while minimize membrane fouling of the membrane filtration system. Hence, it will benefit water industries globally and communities in Australia. There will be a major export opportunity from Australia to supply efficient, low-cost and sustainable flocculant together with an improved treatment system worldwide.Read moreRead less

The effluent streams from molasses based fermentation contain dark-coloured melanoidins (recalcitrant COD) which limit discharge options and make water recovery via membrane technology challenging. Understanding membrane fouling to a level where its behaviour can be reliably predicted is a vital step in gaining widespread acceptance of this technology. Advances made here have a built-in multiplier effect, as insights from yeast production (core business for our industrial partner A B Mauri) can be readily applied to large-scale fermentation producing fuel alcohol from molasses as well as the emerging use of lignocellulosics.
