AI Technical Summary

Technical Problem

Graphene flat sheet membrane modules are susceptible to contamination by impurities in wastewater, leading to decreased membrane flux and increased operating resistance. Existing cleaning methods are inefficient, and the support structure affects the cleaning effect and stability.

Method used

The system employs a gas-liquid mixing turbulent flow cleaning mechanism and a protective grid frame. It utilizes a venturi tube to generate gas-liquid mixing turbulence to drive the cleaning ball to clean the diaphragm. Combined with the support mechanism design, it enables automatic lifting and lowering of the diaphragm and backwashing of the protective grid frame.

Benefits of technology

It effectively removes contaminants from the membrane surface, prevents sludge deposition, extends membrane life, improves membrane separation efficiency, simplifies the installation and disassembly process, and ensures the cleanliness of the bottom of the wastewater tank.
