Ultra-large flow solid-liquid separation filtration system, corrosion resistance, acid and alkali resistance, no wear of filter laminations, and long service life. The built-in computer chip, water pressure sensor collection, and program setting can realize unattended automatic control. Modular design, diverse and flexible product assembly; to meet the needs of different filter flows, theoretically, it can be expanded infinitely. Online automatic backwashing of dirt and impurities, cleaning each unit in turn, sustainable and uninterrupted filtration of water supply. By monitoring the pressure difference between the incoming and outgoing water to determine the clogging degree of the filter laminations, the backwash process can be automatically determined to start the backwash process, and the timed backwash process can also be manually set.           Unique turbine water flow design and laminated spring design, 2.0bar low pressure, 5 (l/s) low flow backwash, saving water and energy. The material is made of stainless steel and PA+ glass fiber, which is anti-aging, anti-UV, sturdy, and durable, ensuring operation and use under various conditions. Flexible pipe connection design to meet the use of different construction design directions. Professional packaging design, while ensuring the safety of product transportation, minimizes the packaging volume and saves transportation costs.
