摘要

The combination of membrane bioreactor (MBR) and reverse osmosis (RO) treatment has proven to be highly effective in the removal of organic pollutants and salts from tannery effluent providing for high quality water recycling.rnMembrane bioreactors (MBRs) combine an activated sludge process with membrane Ultrafiltration to facilitate complete retention of the biomass. This combination results in high bio-mass concentrations leading to an increased removal of organic pollutants and suspended solids from tannery effluent. The MBR permeate is then polished with Reverse Osmosis (RO) membranes to remove salts, which enables high quality water re-use for leather processing. Recycling RO water for leather processing gives excellent results without causing any detrimental effects on leather quality. This combination of MBR and RO technology is shown to be a technical and economically feasible option for effluent treatment and high quality water recycling. An average reduction of 89% COD and 96% BOD and a stable membrane performance was achieved. The effluent quality complies with the Chinese discharge consents for tannery effluents.rnSimona Tanning Inc is a pioneer in implementing this novel hybrid concept of MBR and Reverse Osmosis. The Chinese tannery is retanning bovine leather, processing up to finished product for high performance and specialized leathers for the shoe business. Simona Tanning are giving a special emphasis to environmental protection and safety and are very innovative in respect of new environmental techniques. W20 Environment have assisted Simona Tanning in the successful implementation of MBR and RO technology, which is one of the first industrial scale applications of its kind in Asian tanneries.
