AI Technical Summary

Technical Problem

Existing technologies suffer from poor fine particulate matter purification, inefficient regeneration of filter media, and frequent start-ups and shutdowns, resulting in inconsistent filtration performance and increased operating costs.

Method used

The design combines centrifugal separation with microchannel filtration of the separation medium. It utilizes a backwash inlet and an axial cyclone regenerator to achieve "preliminary release + enhanced regeneration" of the separation medium. By combining centrifugal separation with microchannel filtration of the separation medium, short-circuit flow is avoided, ensuring continuous and stable operation of the equipment.

Benefits of technology

It improves the separation effect of suspended solids larger than 0.5μm in wastewater, reduces filtration pressure, reduces the frequency of equipment shutdown and backwashing, reduces operating costs, and achieves continuous and stable operation of the equipment and high separation accuracy.
