How filters work

How filters work

The water to be treated by the filter enters the body from the inlet, and the impurities in the water are deposited on the stainless steel screen, resulting in a pressure differential. Through the differential pressure switch monitoring into.

When the pressure difference reaches the set value, the electric control gives the hydraulic control valve, drives the motor signal, triggers the following action: The electric motor drives the brush to rotate, the filter is cleaned, and the control valve opens to carry out the sewage, The entire cleaning process only takes tens of seconds. When the cleaning is finished, the control valve is closed and the motor stops rotating. The system returns to its original state and begins to enter the next filtration process.

After the installation of the equipment, by the technical staff to debug, set the filter time and cleaning conversion time, the water to be treated by the inlet into the body, the filter began to work properly, when the preset cleaning time, the electronic control to the hydraulic control valve , The drive motor signal, causing the following actions: the motor drive the brush rotation, the filter to clean, while the control valve to open the sewage, the entire cleaning process only lasts for several tens of seconds, when the end of cleaning, close the control valve, the motor stops rotating, The system returns to its original state and begins to enter the next filtering process.

Filter inside the shell mainly by the coarse filter, fine filter, suction pipe, stainless steel brush or stainless steel nozzle, seals, anti-corrosion coating, rotating shaft and other components.

Filter performance characteristics

1. High efficiency and precise filtration: special structure of the filter plate filter technology, the performance of precise and sensitive to ensure that only the particle size is less than the required particles to enter the system, is the most effective filtration system; specifications are 5μ, 10μ, 20μ, 55μ, 100μ, 130μ, 200μ and so on, the user can choose according to the water requirements of different precision filter disc. System traffic can be flexibly adjusted as needed.

2. Standard modular, saving area: the system based on standard disc filter unit, according to modular design, the user can choose, flexible, interchangeable. Compact system, small footprint, flexible use of corner space for installation, such as the treatment of water 300m3 / h or so equipment covers only about 6m2 (general water quality, filtration level 100μ).

3. Automatic operation, continuous effluent: In the Boyuan Kinka filter combination between the units, the backwash process alternately, work, backwash state automatically switch between, to ensure continuous water; backwash water consumption Less, only accounted for 0.5% of the amount of water; such as with air-assisted backwash, water consumption can be reduced to 0.2% or less. High-speed and thorough backwash, just a few seconds to complete.

4. Long life: new plastic filter components rugged, no wear, no corrosion, very little scaling, after years of practical use of industrial verification, the use of 6 to 10 years without wear, not aging, filtration and backwash effect will not be used Time and worse.

5. High quality, low maintenance: the product meets the corresponding quality standards, all products in the factory are simulated by the test conditions and test run, no special tools, few parts; easy to use, only regular inspection, almost no Need daily maintenance.
