BioFuture - Case Study on BioRemediation of Shing Mun River Hong Kong

In association with our partners, Environmental International Ltd, we present our Case Study on BioRemediation of Shing Mun River.Since 2001, the Hong Kong Government has launched a five-year programme to bioremediate the sediment of Shing Mun River. Nitrates were injected into the sediment to oxidise sulphides and to initiate the aerobic degradation of organics. This process had relied on the degradative activity of the indigenous micro-organisms. Odour problem has been reduced, but the rates of Total Organic Carbon (TOC) breakdown have yet to be assessed. This Paper describes a new method of supplementing the bioremediation. Specially selected natural microorganisms were introduced to the sediment (in-situ) at two locations.
