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.

The KGOL series Self-cleaning Rapid Filter is developed by LAND ECO, for the purpose to solve the difficult and important issue of “self-cleaning and recycling of oily wastewater in metallurgy, petroleum, chemical, thermal power and other industries” indicated in the national document "Catalogue of Water Saving Equipment (Products) Encouraged by the State" announced by the State Economic and Trade Commission and the State Administration of Taxation. (LAND ECO exclusive patent coalescing oil water separation! China Patent: ZL200510101129.2)

GAGS Series High-Performance Oil Water Separator is new device driven by both technologies and rich engineering experience, consisting of GRA modified nano pre-coalescence treatment unit and GOS high-performance oil-water separation unit, which has been widely applied for oily water separation in extractive metallurgies and others with low suspended matters, with handling capacity larger than 5m3/h. Combining two types of water treating processes, the device not only improves the oil-water separation efficiency, but also reduces the investment cost.

The EXTRA Series oil water separation and recovery device is a kind of equipment specially developed on the ground of GOS separator (China Patent ZL200510034499.9), to separate and recover organic phase in the solvent extraction process of non-ferrous metals. As the separation is a physical process only, with no dosing and no dramatic temperature change, which enables the organic solvent staying with its original property. The EXTRA Series device not only can reduce the oil content in water to meet the discharging requirement, help to recover organic phase separated from water with good economic effectiveness, but also can lower the operation load and improve product quality in the follow-up process.

The SRC rotary coalescence filter is a new type of device developed by LAND ECO, combining cyclone centrifugal separation technology and high-performance filtration technology, which is inspired by fish gill that performs unique function of filtration and protection during feeding. With LAND ECO’s special modified material applied as filter material, the performance and efficiency of filtration is outstanding and unparalleled. The SRC filter can be applied for oily wastewater treatment requiring high-precision filtration, especially for the wastewater with high viscosity, such as heavy oil, crude oil or coal tar, or for the pre-treatment before high-precision oil-water separation. After being treated by SRC filter, the emulsified oil and small-size oil droplets in water can get wetting and coalescent, which is very helpful for the follow-up separation.

The LOK series mobile oil water separator combines the rapid filter technology and high-precision oil water separation technology, with LAND ECO’S modified fiber ball and cartridge working as filtering and separating media to achieve excellent performance. LAND ECO supply packaged oily water treatment systems for a variety of industries with discontinuous discharging oily effluents (1~10 m3/h), such as mop water, gas station ground flush, shipboard wash, oil tank draining water as flush water and so on. The portable system can be helpful for the oily wastewater treatment at some trivial but necessary occasions with no installation work and small floor occupation.

GOSK Series Oil Water Separator has been developed based on LAND ECO’s exclusive patent product GOS bi-directional flow surface polymerized high-precision oil water separator (China Patent ZL200510034499.9), for the effluent treatment from air compressor system. As the wetting angle on the contact surface between different solid material and different liquid is 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. Hence, considering the solid material with hydrophobic & lipophilic property as media, the oil droplets would be accumulated, coalesce and separated.

The crucial role of our advanced solution for oil water separation is the LAND ECO modified material.
