what are the advantages of ultrafiltration membrane in the recovery of industrial waste lye?

The ultrafiltration membrane separation technology was used to recover the waste lye from the recycling industry, and the ultrafiltration membrane was designed rapidly to make it a more complete and reliable operation system, so as to achieve the purpose of recovery and reuse of the waste lye. It can be used in many fields of industrial production to realize the double benefits of social economy. So what are the advantages of ultrafiltration membrane in the recovery of industrial waste lye?

Higher recovery rate. The alkali solution dissolved in water can penetrate 100% and the particles are isolated. A small amount of concentrated mixture is discharged, and the recovery rate of lye is more than 95%.

Higher interception efficiency. The high efficiency solid / liquid separation was carried out by ultrafiltration membrane. The separation accuracy was 0.01 m. Most of the suspended and macromolecular substances in the waste liquid were intercepted, and a large number of colloid substances were intercepted in the concentrated solution. Fully ensure the use of recovered lye.

(3) the turbidity (NTU) and chromaticity of the recovered liquid can be reduced to less than 1 and 2, SS (mg/L respectively, and the filtrate is clear and transparent.

(4) the whole process does not need to add medicine, pure physical separation, do not change the effect of use.

(5) Modular design of membrane separation module to determine the number of membrane components according to the amount of waste lye treatment. The design is quite flexible and reliable.

(6) the integrated design of gas and water recoil provides guarantee for long-term, high-efficiency and stable regeneration of waste lye and prolongs the service life of membrane modules.

(7) PLC control, simple operation and good reliability.
