AI Technical Summary
Technical Problem
Traditional membrane separation technology suffers from membrane fouling, uneven shear force distribution, limited cleaning effect, and lack of precise control over flow rate and rotation speed, resulting in unstable separation efficiency.
Method used
It adopts a rotary drum type equal shear membrane separation device, combined with a servo motor-driven drum rotation and an automated cleaning system. The membrane surface is cleaned by a brush distance adjustment mechanism. The flow rate and speed are adjustable, generating uniform shear force to prevent membrane fouling.
Benefits of technology
