Working Principle of front filter 50 Laminated filterPrinciple: it is thin and specific plastic stacks with a large number of micron-sized grooves engraved on both sides. when a string of equivalent-mode stacks are tightened through spring and liquid pressure on specially designed inner supports, the trench crosses between the stacks to form a series of filter units of about 100 microns.When filtering, the water passes through the stack from the outside, and the filter stack is tightly pressed together under the action of each hydraulic force of the spring, and the impurity particles are trapped at the intersection of the stack, filtered water flows out of the filterBackwashing state, when a certain pressure difference or time is reached, the system carries out the flushing controller to control the valve to change the direction of the water flow so that the impurities on the stack are rushed outDisadvantages: incomplete flushing of impurities, uneven filtration accuracy, no sewage outlet
