Three.Operating Principle How Does It Work
A Twisted Pore Adjustment Fiber Filter is an advanced filtration equipment. It utilizes a soft, high-strength curved fiber yarn with stable performance and high single-filament strength as the filter material, combined with an electrical control system to achieve the filtration treatment of raw water. It boasts high filtration accuracy, large flow rate, and relatively small land occupation.
Twisting pore controll fiber filter is an advanced filter equipment. It USES a kind of stable performance, high strength single filament soft, high strength curved fiber filament as the filter material, with the electronic control system, to achieve the filtering of raw water treatment, which has the advantages of high filtering accuracy, large flow, relatively small cover area.
Different from traditional vertical filtration methods, this filter allows the feedwater to pass through the filter media horizontally, thus enabling greater flow rate and volume for equipment of the same diameter.
Different from the traditional longitudinal flow filtration method, the incoming-water is transversely through the filtration layer, so with the same diameter the equipment can achieve a larger flow velocity and flow rate.
1.Filter StatusFiltering
As shown in the right figure, the rotating mechanism set on the outside of the tank drives the filter unit to rotate, tightly wrapping the PP fiber bundle around the central water pipe, forming a uniform, fine, and dense porous filter layer. The filtered water passes through this filter layer from the outside into the central water pipe, thus trapping and adsorbing impurities in the water. During the filtration process, the pre-filtered water system passes through the filter layer horizontally, as the PP filter fibers are arranged in a regular pattern, preventing any bias flow phenomenon.
As shown in the figure on the right, the rotating units outside the tank drives the filtration module to rotate, so that the PP fiber bundle is tightly wound on the central tube，forming a uniform, tiny and dense porous filtration layer.through which the incoming water enters the central tube from the outside, thereby retaining and adsorbing the sewage in the water. In the process of filtration, the incoming water goes through the filtration layer in a horizontal direction. Because the PP filter wires are arranged in a certain rule, the bias phenomenon will not occur.
|
A certain quantity of soft PP fiber bundles are wrapped longitudinally around the central drain pipe, forming a filter unit. Depending on the specifications of the filter, one or four filter units are set up inside the tank.
A certain number of fine PP fiber bundles are longitudinally wrapped on the central gathering pipe to form a filter unit. One ｏｒ four sets of filter units are set in the tank according to the size of the filter specifications.
The surface area of the four filter elements inside the equipment is greater than the cross-sectional area of the tank, allowing for a high theoretical filtration rate of up to 100m/h. Generally, it can reach 60 to 80m/h. Taking a DN2000 twist-type pore regulating fiber filter as an example, its flow rate can reach 200 to 300 T/H, while a standard DN2000 high-efficiency fiber filter typically operates at a flow rate of 30m/h, with a corresponding flow rate of 94T/H.
The surface area of the four filter cartridge in the equipment is larger than the cross-sectional area of the tank, so its theoretical filtration rate can be up to 100m/h. Generally, it can reach 60 ~ 80m/h. For example, the flow rate of DN2000 torsional pore regulated fiber filter can reach 200 ~ 300T/H, while the conventional flow rate of DN2000 high efficiency fiber filter is 30m/ H, and the corresponding flow rate is 94T/H.
2.Backwash stateBackwashing
When the retained material increases and the differential pressure (or flow rate, operating time) reaches the set value, the system automatically enters the backwashing step. During backwashing, the external rotating mechanism drives the PP filter fibers to be fully relaxed. Under the combined action of the backwashing water flow and cleaning air, the retained dirt is washed off and discharged through the drain line. After cleaning, the system can automatically return to the filtering state or enter standby mode.
When withholding content increased, the differential pressure (flow rateor Running time) to set data, automatically enters backwashing steps. The rotating units outside the tank drives the filtration module thoroughly relaxed, under the joint action of the backwashing water and compresses air, the elution of sewage intercepted is discharged through the drainage pipe, after cleaning can automatically enter the filtering state ｏｒ ino standby state.
|
During the anti-washing process, the introduction of clean air causes the PP filter fibers to produce intense vibrations and friction with each other while being cleaned. Added to this is the effect of the clean air, which makes the retained substances on the filter fibers easily shed under the combined scrubbing of the backwash water flow and the clean air. Furthermore, the rotating mechanism drives the filter fibers to repeatedly perform rotation and relaxation actions during the anti-washing process, which contributes to achieving a better anti-washing effect similar to that of a washing machine.
The compressed clean air, make PP fiber bundle in the process of cleaning produce strong jitter and rubbing against each other, and Plus the carrying effect of cleaning air,the sewage intercepted on the fiberbundle can be easily peeled off by the combined washing water and cleaning air. In addition, the rotary mechanism drives the filter wire to repeat several times of rotation and relaxation during the backwashing process, which is helpful to obtain better backwashing effect similar to that of washing machine.

1. Usage PrecautionsOperational Considerations
1) When setting the backwashing pressure (0.5-0.8 kg/cm²), do not set it too high, otherwise it may cause deterioration of filtered water quality, reduced water flow, and abnormal drainage.
Set back flush pressure (0.5-0.8㎏/㎝2), don't set too high,ｏｒ will cause deterioration of water quality, water flow reduction and abnormal exhaust pipe, etc.
2) Install regulating valves and check valves at the raw water inlet; install check valves at the backwash inlet.
Install regulating valve and check valve at raw water inlet; install check valve at backflush inlet.
3) Absolutely no reaching into or inserting any objects into the gear area while the machine is in operation.
It is strictly prohibited to reach for ｏｒ put other objects ito the rotary gear under the running state.
4) After shutdown, be sure to rinse the filter fibers repeatedly to thoroughly remove water from inside the filter (ensuring the filter fibers do not stick to any suspended particles. If not rinsed clean, it will reduce the filtration efficiency).
After the filter is shut down, it is necessary to repeatedly flush the filter fiber, and completely remove the water inside the filter (makng filter fiber filaments free of suspended solids; if not, the filtering effect is reduced)
5) Perform a chemical soak cleaning at least once a month, using disinfectants such as CaCLO2 or NaCLO (with a CL concentration of 20ppm) to soak the filter for at least 12 hours, followed by a gas-water mixture flush to remove algae and microorganisms from the filter material fibers.
Soak and clean at least once a month. Infuse disinfectant such as CaCLO2 ｏｒ NaCLO (CL concentration is 20ppm) to the filter and soak for at least 12 hours. Then mix air and water to rinse and remove algae, microorganisms and other substances on the filter fiber.
6) We recommend removing all valves every three months and thoroughly cleaning out any foreign matter with a soft cloth.
It is recommended to remove all the valves once every three months and thoroughly remove the foreign bodies with soft cloth.
7) To prevent rust on the worm gears, it is necessary to apply lubricant regularly.
To prevent rotary gear from rusting, grease should be applied regularly.
