Cloth Media Filter

Equipment characteristics

The fiber rotary filter is composed of a central drum, turntable, backwashing system and supporting control electrical system. The turntable is fixed around the center drum and has a communication hole with the center drum. The raw water (sewage) flows into the drum through the opening at one end of the central drum, and enters each turntable through the communication hole. Filter cloth is installed on both sides of the turntable. The filter cloth is woven of stainless steel wire or polyester wire. 10μm. After the raw water is filtered through the filter cloth, clean water flows out of the filter cloth and is discharged out of the system from the filtered water outlet. As the filtration proceeds, the trapped impurities inside the filter cloth continue to increase, the filtration pressure difference increases accordingly, and the amount of water passing through the filter cloth decreases. When impurities accumulate to a certain degree, the center drum liquid level reaches the set value, and backwashing is required to wash out the impurities accumulated inside the filter cloth. The backwash water pump draws clean water through the filter cloth and sprays it to the outside of the filter cloth to wash off the trapped impurities on the inside of the filter cloth. After washing, the sewage drops into the drip tray and then is discharged outside the device. During backwashing, the turntable rotates and the backwash water sprays filter cloths at different angles until the turntable rotates once. All the filter cloths are cleaned, backwashing stops, and the static filtration process is re-entered until backwashing is performed again.
