AI Technical Summary
Existing automatic backwashing membrane filters require long-term shutdowns during the backwashing process, resulting in reduced system processing capacity, increased energy consumption, and equipment wear. Furthermore, frequent shutdowns and restarts increase management complexity and costs.
An automatic backwashing membrane filter was designed. By rotating the filter tube counterclockwise through a rotating component, the filter tube is connected to the inlet water pipe for reverse flushing, reducing downtime and cleaning during the filtration process, thereby improving treatment efficiency and lifespan.
It effectively reduces downtime, improves wastewater treatment efficiency, extends the service life of filter tubes, and reduces operating and management costs.
