In the production process of enterprises, after repeated use of water washing and other processes, the water will contain oil. If you want to recycle the water for continued use, you need to separate the oil from the water to extract the oil from the water. The treatment methods for oily wastewater are mainly divided into physical and chemical methods, chemical methods, and biological methods according to different principles. Each method has its own advantages and limitations, so it depends on the actual situation during actual use.

Use the centrifugal extractor and solvent extraction method to separate oil from water. Solvent extraction is to select a suitable extractant and use it to extract the oil in the water. After oil-water separation, the oil content in the water phase is less than 3g/L, which can meet the discharge standard and can be recycled.

Process Flow of Oil-water Separation in Centrifugal Extractor

  1. Firstly, pass water. After the water phase is discharged from the centrifugal extractor, start to enter the mixed phase of water and engine oil. The engine oil and water are separated by the centrifugal extractor.
  2. The water containing a very small amount of oil enters the filter device again, so that the oil content in the water can meet the national emission standards (less than 3g/L).

CWL-M Centrifugal Extractor

CWL-M centrifugal extractor is a fast and efficient liquid-liquid extraction and separation equipment. It uses the high-speed centrifugal force to achieve mixed mass transfer and separation of two liquids with different densities and immiscible with each other.

  1. Low power consumption. The power consumption of centrifugal extractor is only 0.18kw, which is about 1/7 of the power consumption of traditional equipment.
  2. The bottom seal is cancelled, which completely solves the problem of bottom leakage and easy damage of the machine seal of traditional models.
  3. Simple and stable structure, simpler operation and smoother operation.
