Fourth, working principle
The  rotary disc type micro-filter process is composed of a central drum, a rotary disc, a backwash system, and supporting control electrical systems. The turntable is fixed around the center drum and has a communication hole with the center drum. Raw water (sewage) flows into the drum from the opening of one end of the central drum, and enters each of the turntables through communication holes. Filter cloths are installed on both sides of the turntable, and the filter cloth is woven with stainless steel or polyester wires. 10 μm. 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 through the filtered water outlet. With the progress of filtration, the trapped impurities on the inside of the filter cloth continue to increase, the filtration pressure difference increases, and the amount of water passing through the filter cloth decreases. When the impurities accumulate to a certain level and the liquid level of the central drum reaches the set value, backwashing is required to backwash the impurities accumulated inside the filter cloth. The backwash water pump draws the clear water that passes through the filter cloth, sprays it on the outside of the filter cloth, and flushes out the trapped impurities on the inside of the filter cloth. After the flushing, the sewage falls into the drip tray and then is discharged out of the device. During the backwash, the turntable rotates, and the backwash water is sprayed with filter cloths of different angles until the turntable rotates once. All the filter cloths are cleaned, the backwash is stopped, and the static filtration process is re-entered until the backwash is performed again.
The rotary disc type micro-filter adopts imported high-efficiency filter cloth as the filter medium. The filter cloth is woven from the metal wires of special warp and weft threads. It has the characteristics of high precision, high flux, high strength, and strong slag accumulation. High filtration accuracy can reach 10um, the unit area flux can reach 76L / s • m2 (@ 300mm hydrostatic head), and it can withstand the backwash pressure of 7.5bar, effectively improving the backwash effect. With the progress of filtration, the trapped impurities on the inside of the filter cloth continue to increase, the filtration pressure difference increases, and the amount of water passing through the filter cloth decreases. When the impurities accumulate to a certain level and the liquid level of the central drum reaches the set value, backwashing is required to backwash the impurities accumulated inside the filter cloth. The backwash water pump draws the clear water that passes through the filter cloth, sprays it on the outside of the filter cloth, and flushes out the trapped impurities on the inside of the filter cloth. After the flushing, the sewage falls into the drip tray and then is discharged out of the device. During the backwash, the turntable rotates, and the backwash water is sprayed with filter cloths of different angles until the turntable rotates once. All the filter cloths are cleaned, the backwash is stopped, and the static filtration process is re-entered until the backwash is performed again.
The raw water enters the center drum from the central water inlet pipe, and enters the filter disc fixed around the drum through the water distribution hole of the center drum. The filter cloth woven with stainless steel or polyester wire is installed on both sides of the filter disc. After the raw water is filtered through the filter cloth, the clear water flows out of the filter disc and is discharged from the water outlet weir. With the continuous filtering, the impurities trapped on the inside of the filter cloth increase continuously, the clear water flowing out of the filter disc gradually decreases, and the water level in the disc keeps rising. When the liquid level in the filter disc reaches the set value, the drum starts to rotate. The high-pressure water provided by the backwashing device automatically flushes the surface of the filter disc, and the impurities then fall into the dirt collection tank fixed inside the filter and enter the sludge pipe for external discharge. With the continuous rinsing, the water level in the pan continues to drop. When the set liquid level is reached, the backwash automatically stops, the drum also stops rotating, and the system re-enters the static filtration process.
The backwashing stage does not affect the operation of the device. The filter operates in continuous water inflow, staged backwash, and continuous water outflow.
