About Surfcleaner

SURFCLEANER is an innovative company that provides solutions for oil recovery, purification of dams, harbors and seas.


How it all began

SURFCLEANER is part of Inovacor. Inovacor is basically a development company with products based on the discovery (Lundbäck 1979-1986) how the heart performs its pumping and auto-regulating functions as a previously unknown pump technology DAPP (Dynamic Adaptive Piston Pump). This patented technology has in recent years been used in the industrial sector.

Present times

SURFCLEANER has a proven technology and can separate thin oil sheen and heavy oil, debris and solids. There are major environmental problems of litter in our oceans and lakes, of industrial pollution and of oil spills at sea. For cost reasons, the oil sometimes is lowered to the bottom. We have developed our new models that can help solve these problems in a cheap, environmentally friendly and efficient manner.


Phase 1

In the bottom of the SURFCLEANER there is a propeller that creates a negative pressure. This pressure first affects a membrane, which constitutes a part of the ceiling of the underwater body, then a bellow and a circular floating ring creating the inlet zone. The floating ring follows the water level and therefore the collecting of pollutions will not be affected by waves. Due to the shape of the SURFCLEANER and to the negative pressure, the circular floating ring will be drawn down under the water surface and a circular inflow zone will be created. The carrier fluid with the polluting surface layer will flow into the SURFCLEANER and equilibrium between the inflow and the outflow will be established. The circular inflow zone together with the lowering of the water level creates forces, which concentrate the surface layer into the centre of the inflow zone.


Phase 2

When a sufficient thickness of the surface layer has been concentrated in the centre of the inflow zone, the flow of the carrier fluid will pull the collected surface layer down towards the bottom of the SURFCLEANER. With deflection disks the carrier fluid and the pollutant is forced out in the periphery of the SURFCLEANER and thereby a dramatic lowering of the flow velocity occurs. The low flow velocity results in a diverging of the pollutants upwards towards the ceiling of the underwater body while the carrier fluid is continuing down towards the propeller and out through the outlet.




Phase 3

The collected surface layer can be dealt with in many different ways. Either the surface layer can be taken up during the concentration phase or it may be disposed in or after the phase separation. By reversing the propeller, a positive pressure (eg 0.2 bar) is generated in the water body. This pressure affects the membranes of the submerged body ceiling to form an opening in the centre of the SURFCLEANER. The overpressure impacts the bellow and the circular floating ring to close against a seat on a waste pipe. In this way pollutants may, with the carrier liquid as a piston, automatically be transported to a suitable external storage tank of disposable or reusable nature. A sensor connected to the control system makes it possible to achieve an automatic emptying of SURFCLEANER.

SURFCLEANER operates at high flow and low pressure (P (W) = Q (m³ / s) * P (N / m2)) which means that the energy consumption is low.

Short summary:

  • The systems can separate from extreme thin oil sheen (1000Å) to heavy oil layers.
  • Has low energy consumption and can be powered by solar energy.
  • Separates surface layers with low to high viscosity.
  • Separating capacity, the emptying phase inclusive, up to 12 m3 pure oil per hour.
  • Separation directly at the surface – minimum transport of liquid
  • The collected pollutant is free from water.
  • Unattended long time cleaning of oil spill and oil sheen.
  • Can be installed in existing plants.
  • Minimal mechanical wear – low service costs.
  • Motor unit have magnetic drive – no sealing problems.

Easy handling and service with portable modules

SURFCLEANER is constructed by means of portable modules to enable easy transport and service. The system contains only two moving parts, the bellows and the propeller. Thus, SURFCLEANER has low noise during operation and it is particularly suited for continuous and prolonged operation. The construction ensures minimal mechanical wear resulting in low service costs.

Traditional Surface Removal

Thin layers – static separation, thick layers – skimming
It requires heavy equipment and installations – slow and costly processes
Difficult and time consuming to clean
Poor cleaning factor – final mechanical separation required

Self-regulating the continous and unattended operations

SURFCLEANER is completely self-regulating. Unlike traditional technique skimmers SURFCLEANER is not affected by heavy seas, variations of the water levels or changes in the thickness of the surface layers. SURFCLEANER is made of stainless steel and polyester suitable for continuous operation for long time in demanding marine and industrial environments.
