Ponds, lakes and lagoons that have become stagnant, full of algae and scum and emit putrid odours, lack oxygen that kills off the natural eco systems that exacerbate the problem. Traditionally, ponds have been dredged, treated with chemicals and enzymes and, in some cases, concrete lined. These methods are very expensive and generally do not work due to the anaerobic nature of the environment. The use of chemicals is very expensive, requires specialist, protective application, killing the natural environment and usually requires the sludge to be disposed of by road transport.
Why dredge up the problem when you can eliminate it?
Traditionally, waste water companies use machinery and chemicals to remove weed build-up and ‘mask’ odours. Not only is this practice damaging to the environment, it does not deal with the problem at source.
