Mobile oil-water separators are mainly used for cleaning stationary oil interceptors or catch basins for oily wastewaters or bilge oils directly on site. In general, the contents of these basins and containers are completely sucked off by a vacuum truck. Instead of sucking off the phases oil, water and sludge together, the single phases can be separated directly on site by the mobile oil-water separator. Possibly long transports for disposal can thus be avoided.
OKO-aquaclean plants remove reliably – monitored by sensors - the oil from the water. The purified water is then returned into the stationary interceptor – refilling with fresh water is not necessary. Alternatively, the water can be irrigated or discharged into the sewer. Mobile oil-water separators offer a resource-saving and cost-effective method not only in this respect – as the water is separated from the material to be disposed of, only sludges and oils have to be transported. The amount of waste is reduced, making disposal more cost-effective.
For repeating leak tests and for reconstruction works, mobile oil-water separators are indispensable, as they replace a vacuum truck. As part of emergency measures for an oil spill response team in case of accidents and damage, mobile oil-water separators are used to fight environmental damage. Another field of application is groundwater remediation.
The use of sensors enables the controller to direct, monitor, and log the quality of the clear water going out. Authority requirements concerning the documentation of water quality are thus reliably met.
The mobile versions of the OKO-tech wastewater treatment plants are also designed in modules, as a matter of course. The basic unit, a type-approved oil-water separator in line with EN 858, can be optionally equipped with a coalescer and other modules, such as flotation or an emulsion-breaking unit.
Basically, the OKO-aquaclean systems consist of a stainless-steel reactor with a patented flow guide. The reactor is divided into several chambers through which the waste water flows continuously in meanders. A progressive cavity pump feeds the waste water to be treated.
After passing through the reactor, the clear water flows to the discharge point or the collection point, either by gravity or by means of a water conveyor pump. The oil or the flotation froth separated is collected in an integrated chamber which is electronically protected against overfilling.
OKO-tech systems for treating industrial wastewaters have a small footprint thanks to their compact design. Sizes vary according to performance and throughput quantities. As mobile oil-water separator, they are mounted on a single-axle trailer, a tandem trailer or as a special structure, so that they can be transported easily to the site of operation.
When cleaning oil interceptors, the use of the mobile oil separator OKO-aquaclean® provides a significant savings potential for fuel costs and an improvement in the ecological balance by reducing CO2 emissions.
Conventionally, a vacuum truck will suck in the entire content of the oil interceptor. The phases oil, water, and sludge are carried off together - thus causing a high volume to be disposed of. The limited storage capacity of the vacuum truck is therefore unnecessarily occupied and more transport trips to a disposal facility, possibly far away, are necessary.
The use of a mobile oil -water separator OKO-aquaclean® in connection with a suction truck can save considerable costs when cleaning a stationary oil interceptor. This is mainly due to the fact that the different phases are sucked off separetely. The oily water phase in the interceptor, which is otherwise completely sucked in by the vacuum truck, is now sucked off by the OKO-aquaclean® system which reliably separates the oil directly on site. The vacuum truck will only carry off the usually small amounts of oil and sludge from the interceptor. The purified water does not need to be removed and can be used for refilling.
The number of trips to the disposal facility is reduced to a minimum, resulting in lower fuel costs and reduced CO2 emissions. It is possible to serve significantly more customers per day (five on average), since the suction truck has to take in much less waste. In addition, no fresh water is needed for refilling the interceptor.
Mileage vacuum truck per year: 100,000 km
Total fuel consumption: 45,000 l
Fuel costs (currently approx. 1 €/l) 45,000 €
CO2-emissions here: 117,000 kg
(According to the Federal Environmental Agency, one liter of diesel burns to 2.6 kg of CO2.)
This corresponds to 36,000 €/year for fuel costs and 93,000 kg for CO2 emissions - a significant contribution to environmental protection and cost efficiency!
OKO-aquaclean® plants are characterized by high-quality technical equipment, robustness, ease of use and ease of maintenance.
These criteria, coupled with low investment, lead to the profitability already proverbial among experts and amortisation periods often shorter than 12 months.
