Based on the differences in the properties of water oil dispersion systems and using the state and particle size of oil as variables, our company's wastewater oil removal equipment is used to achieve step-by-step separation.

Tank within Tank - Coupled with sedimentation and cyclone separation technology and equipment, it separates suspended solids, floating oil, and large particle dispersed oil in wastewater. The final oil removal effect can reach: sewage oil content ≤ 150mg/L

Horizontal oil-water separator - coupling coarse-grained materials and polymerization technology, inclined plate polymerization separation technology, equipment. For different particle oil droplets, coalescence separation can achieve a final oil removal effect of ≤ 50mg/L oil content in wastewater.

Fine essential oil water separator - updates coarse-grained polymer materials  based super oleophilic and hydrophobic polymer materials, intelligently couples, captures emulsified oil and partially dissolved oil, and achieves high oil-water separation. The final oil removal effect can reach: the oil content in sewage is ≤ 20mg/L.

The oil-water separator produced by our company is usually used in heavy load operations. Our technology has been widely applied in various industrial fields that generate oily wastewater, such as petrochemicals, coal chemicals, coking, steel and power, new energy materials, oil storage tank areas, port terminals, and oilfield re-injection. This means that they adopt excellent engineering design and high-quality surface treatment processes, enabling their service life to reach 28 to 30 years.

1. Physical Law

Gravity separation: using the density difference between oil and water to achieve separation, such as natural settling tanks, oil separators, etc., suitable for removing floating oil, but with a large footprint.

Centrifugal separation: Hydro-cyclones are widely used due to their small size and high efficiency, especially for the pre-treatment of oily wastewater from ships.

Membrane separation: Ultra-filtration/reverse osmosis technology has significant effects on the treatment of dissolved oil and emulsified oil, but the membrane cost is high and prone to contamination, making it mostly used in high-precision scenarios.

Agglomeration oil removal technology: Combining the dual mechanisms of wetting agglomeration and collision agglomeration, small oil droplets are adsorbed and agglomerated into large oil droplets through lipophilic/oleophobic materials (such as corrugated plates, fiber fillers, and agglomeration filters) to accelerate oil-water separation. Typical equipment includes a horizontal oil-water separator and an efficient coalescing oil remover, which are suitable for removing 10-20 μ m small dispersed oil particles and have the advantages of short residence time and small footprint.

2. Chemical method

Coagulation/Air Floatation: Combining chemical demulsification with air flotation separation, such as the combination process of inclined plate air flotation and walnut shell filtration.

Electrochemical method: Electrical flotation technology can replace traditional air flotation, with lower energy consumption, but higher equipment investment.

3. Biological Law

Aerobic/anaerobic treatment: such as activated sludge process and biological contact oxidation process, suitable for the degradation of organic matter in oily wastewater in ports, but requiring supporting pretreatment measures.

Coalescence is the process of two or more droplets or bubbles of a substance merging into one larger droplet, which filter out easily because they are heavier. Coalescence filtration can remove matter as tiny as 0.1 microns or smaller.

The hydro-cyclone can achieve the separation of oil and water through a swirling centrifugal process based on the density difference between the two media.

No, Hydro-cyclone Oil Separators are primarily designed to separate free-floating or non-emulsified oil from water. This type of oil is typically less dense and rises to the surface, making it easier for hydro-cyclones to separate through strong centrifugal forces. However, emulsified oil consists of much smaller oil droplets that are dispersed within the water, often stabilized by chemicals or surfactant. 

These tiny particles are much harder to separate because they are tightly mixed with the water, creating a stable suspension that doesn’t respond well to the centrifugal action of a Hydro-cyclone. 

To effectively remove emulsified oil, additional treatment processes such as chemical dosing, which breaks down the emulsion, or coalescing separators, which allow small oil droplets to merge into larger ones, are typically required. These methods are better suited for handling emulsions and are often used in conjunction with Hydro-cyclone in complex oil-water separation systems to ensure thorough treatment of wastewater.
