Compact Aerobic Bio-Reactor
There are many situations where the major contaminants in a waste stream are dissolved organic materials. These increase the cost or even prevent the discharge of waste to the public sewer or watercourse and often exclude the re-cycling of the water. One approach is aerobic treatment in a biological plant. The traditional processes are very large (with consequential high capital cost) and are quite limited in the strength of waste they can handle.
Note: Biological Oxygen Demand (BOD) is a measure of the pollution content of an effluent. It measures the amount of oxygen needed by the bacteria to oxidise the pollutants in the water. This value will normally have to be lower than 400ppm (or mg/l) for discharge to public sewer (with subsequent costs for processing the waste) or below about 20 ppm for re-use or discharge to a watercourse. The charges for processing industrial effluent in the UK depend to a significant extent on the BOD. The lower the value, the lower the cost.
Biological effluent plants in the medium sized industrial site should be able to process high strength or high volume waste where space is at a premium, specialist staff are not available and low operating and capital costs are desirable. Traditional aerobic and anaerobic processes are complex, large, expensive or all three.
WMEC EnviroBAFF
WMEC are able to offer a new version of aerobic bioreactor which works much more intensively than the traditional activated sludge plants, requires less space and covers a wider range of concentrations and waste flow. The WMEC EnviroBAFF, distributed by arrangement with the developers, Envirobac Ltd, is particularly suited to the medium sized industrial site with a high BOD problem, but who would not have considered a traditional biological treatment plant on the grounds of cost or space.
The EnviroBAFF is a unique, patented treatment system using the submerged fixed film principle. In this environment, bacteria grow in films on a surface immersed in the effluent stream and oxidise the biodegradable waste. In the EnviroBAFF the bacteria grow on the surface of specially structured honeycomb like media and are intensively aerated by a unique diffuser system.
