Oil accidents in water are not uncommon. To prevent the worst, disaster relief and fire services provide decontamination units. Depending on the situation, they are able to detoxify up to 40,000 or 160,000 liters of oil/water mixture in one hour. Three Börger Rotary Lobe Pumps are incorporated in the plant. A mobile, self-priming Börger feed pump takes in the contaminated medium and transfers it to the plant. The pump is enclosed in a Euro mesh pallet sized frame and able to feed at controlled speeds using a built-in frequency converter.
The pumps in the plant are also frequency-regulated. After the mechanical separation of oil and water, another Boerger Rotary Lobe Pump transfers the separated, highly viscous oil into a tanker vehicle. A larger Börger pump is used to transfer the separated water back to the tank if it still contains oil or pumps it back to the contaminated water to be detoxified completely. The Boerger Rotary Lobe Pumps were chosen for their compact design, gentle pumping and excellent control characteristics.
