With the increasing water consumption and discharge of industries such as pharmaceuticals, chemicals, pesticides, etc, the environmental pollution caused by high concentration organic wastewater is becoming more and more serious. Organic COD is generally above 2000mg/L, and some are even as high as tens of thousands or even hundreds of thousands of mg/L. Sometimes the color is high and there is a peculiar smell, which has a negative impact on the surrounding environment.

At present, there are many treatment methods suitable for high concentration organic wastewater. Among them, the solvent extraction method not only requires small equipment investment, occupies a small area, has low energy consumption and is easy to operate, but can also recover valuable substances in the wastewater. Experiments have shown that the solvent extraction method is very effective. After oil removal and extraction, the COD removal rate of the wastewater is as high as 96.47%.

The CWL-M series centrifugal extractors launched by Zhengzhou Tiei Extraction Company can turn waste into treasure for phenol-containing wastewater. This series centrifugal extractors is a new product with independent intellectual property rights owned by Zhengzhou Tiei Extraction. Under the same processing capacity, the power consumption of the CWL-M series centrifugal extractors is only 10% to 30% of that of traditional annular gap type machines. At the same time, the centrifugal extractor has a short stage retention time, rapid phase separation, high extraction efficiency, and saves investment costs and solvent recovery and regeneration costs.

CWL-M Series Centrifugal Extractor Features

  1. Adopted the upper suspension single-point structure, and no bottom bearing and mechanical seal in the processing area, and no risk of leakage. It can solves the problem of frequent failures and short service life of centrifugal extractors and saves equipment maintenance costs.
  2. Corrosion resistance - the equipment can be made of perfluorinated polymer materials, which can resist corrosion from strong acids (hydrochloric acid, mixed acids, etc.).
  3. A variety of mixed structures are optional, with high separation effect, which can be applied to easily emulsified systems.
  4. When the liquid system changes, the heavy phase weir plate can be quickly replaced, and the operation is simple and convenient.
