l The filtration system is a type of automatic filtration system designed to filter large flows, any water quality, and to satisfy various installations at any time.It has fully automatic filtration, cleaning and sewerage functions. Special-purpose backwash controller, control method with pressure difference sensing and time setting
l A laminated filter containing a spiral structure has a good centrifugal effect. During filtration, the water stream rotates at high speed to remove dirt from the laminations and produce a good filtering effect. Grooved filter laminations serve as the core elements of the filter for more thorough and accurate 3D deep stereoscopic filtering.
l Large amount of water treatment, each unit is only a standard unit, through the combination of units to achieve a large flow of processing, combined loading and unloading
