      1.Long lifespan.

　　2.Large filtration capacity and high filtration efficiency

　　3.Fast filtration speed, normal filtration speed can be around 40m/h, up to 60m/h depending on water quality; the filter backwashing uses product water, and no booster pump and backwashing pump are needed; backwashing time is 2-3min, backwashing water volume <3m3.

　　4.High filtration accuracy, impurity filtration accuracy can be below 0.10mm, effluent turbidity can be less than 0.5NTU. The filtration system consists of standard unit sand tanks, and the filtration flow rate can be increased from 30.6 cubic meters/hour to 2500 cubic meters/hour.

　　5.Automatic backwashing: The backwashing of this equipment is automatically identified and controlled by an intelligent control system, without manual intervention, even if the suspended solids in the water fluctuate, the equipment can automatically adapt.

　　6.Uninterrupted water supply; during the backwashing of this equipment, the filtration process continues simultaneously, and the system supplies water as usual.

So what are the performance advantages of fully automatic backwashing sand and gravel filters for irrigation? Save maintenance costs: The entire system has no mechanical or electric valves, only relying on a unique multi-functional valve to control the system's backwashing. Due to the unique multi-functional valve's wear resistance and long lifespan, there is no damage record within 10 years, resulting in low management costs.
The shallow sand and gravel filter dual-tank parallel connection is generally installed at the front end of the header device, and the water source is pumped into the filter equipment for preliminary filtration by the water pump. In this way, impurities, suspended solids, and small particles can be intercepted and filtered out before being discharged from the drain port. The finer the filter material, the higher the filtration accuracy, the smaller the flow rate, and the greater the water resistance; the coarser the filter material, the lower the filtration accuracy, the larger the flow rate, and the smaller the water resistance. Currently, our company recommends the use of 2-4mm quartz sand as the medium, which can effectively block particles larger than 150 mesh, while for processing particles larger than 200 mesh, a sand and gravel filter is not suitable. Shallow sand and gravel filter dual-tank parallel connection can be used alone, or multiple combinations or combinations with mesh filters and disc filters according to the irrigation project usage and filtration requirements. As a primary filter for mesh and disc filters.
