Oil-Water Separator — GOS High Performance Series
In order to solve the oily water recycling problem in oil refining, petrochemical and thermal power industries according to the Water Saving Guide issued by the National Development and Reform Commission, LAND ECO has developed GOS bi-directional flow surface polymerized high-precision oil water separator (LAND ECO exclusive patent coalescing oil water separation! China Patent ZL200510034499.9) The working philosophy is wetting coalescence of coarse-graining principle. As the wetting angles on the contact surface between different solid material and different liquid are different. When the wetting angle difference of two types of liquid on the same solid material surface is greater than 70 degree, these liquid can be separated from each other. Further, according to the Stokes Law, the floating speed of oil droplet in water is proportional to the square of its diameter. With the size getting bigger, the oil droplets would move upwards quickly and separate from water finally. While fluid with oil going through the LAND ECO filtering media, the oil would get coalescent upon contact. As the filtering media of LAND ECO cartridge is so effective, our separator can achieve critically low oil-content levels to meet the most stringent environmental and process requirements.
