What is the difference in the working principle of the filter element in different types of filters

What is the difference in the working principle of the filter element among the different types of filters? Today, we will take for example the fact that the fully automatic brush filter and the hand-operated brush filter both belong to the brush filter, although the two types of filters are different, their main functions are the same. They are both for filtering impurities and particulate matter, purifying water quality, and reducing the turbidity of water, at the same time to reduce dirt and ensure the operation of the entire system. What is the difference between automatic brush filter and hand-operated brush filter in working principle? (1) the water to be treated by the automatic brush filter enters the machine body through the water inlet of the automatic brush filter. Impurities in the water are deposited on the stainless steel filter screen, resulting in a differential pressure. The pressure difference of the inlet and outlet is monitored by the pressure difference switch. When the pressure difference reaches the set value, the electric controller feeds the water power control valve and the driving motor signal, which causes the following actions: the motor drives the brush to rotate, and the filter element is cleaned, at the same time, the control valve is opened to drain, and the whole cleaning process only lasts for tens of seconds. When the cleaning is finished, the automatic brush filter closes the control valve, the motor stops rotating, and the system recovers to its initial state, proceed to the next filtering step.

(2) hand-shake brush filter hand-shake brush filter is a semi-automatic cleaning filter. It uses the built-in brush and brush holder of the filter screen to brush away dirt, impurities and other particles on the filter screen before discharging through the sewage valve. The two comparison: hand-brush filter belongs to semi-automatic filter, with fully automatic brush filter compared to the disadvantage is time-consuming and laborious, but also manual cleaning. Brush filter adopts the advanced technology of international water treatment industry, devotes to the design, manufacture, equipment, commissioning and service of water supply system, circulating water system, sewage system and reclaimed water system. In order to effectively enhance the urban and rural residents living water, to ensure the safety of urban and rural residents drinking water quality, brush filter has become one of the major help.
