The rotary disc filter is composed with rotary drum, rotary discs,
backwash system and configured electrical control system. The
rotary discs are fixed around the rotary drum with interlocking
holes. The raw water (sewage) flows from the open end of rotary
drum into the rotary drum and comes into each rotary disc via
interlocking holes. The rotary disc can be equipped with filtration
cloth on both sides that is weaved by metal wire or other organic
materials with the diameter of filtration hole less than 10μ m.
After the filtration of raw water by filtration cloth, the clean
water flows out from the filtration cloth and then drains off the
system through the exit of filtered water.
With ongoing filtration, the residual impurities inside filtration
cloth will increase continuously, and the same is true for
differential pressure of filtration. Meantime, the water flow is
reduced through the filtration cloth. When the impurities are
accumulated to a certain extent and the level of rotary drum
reaches the preset value, it is necessary to conduct the backwash
and get rid of the accumulated impurities inside filtration cloth.
The backwash water pump draws out clean water through filtration
cloth to sprinkle on the outside of filtration cloth until the
residual impurities come off. After rinsing, the sewage drops into
catchment tray and then drains off the device.
The rotary discs take the spinning in the process of backwash. The
back wash water sprinkles upon different places of filtration cloth
until the rotary discs run one circle. After the thorough cleaning
of filtration cloth, the backwash comes to the end and restores the
static filtration process until the next backwash starts.
