The filtration system in the irrigation sand filter is composed of one or more standard high-speed filtration units. The raw water passes through the internal water distributor and filter layer collector, and the filter layer medium is used to effectively remove suspended solids and reduce the turbidity of water quality (if the specific filter materials such as activated carbon and anthracite are loaded, the corresponding organic matter and harmful ions can also be adsorbed and removed).
Irrigation sand filter is often installed in the head of agricultural irrigation system as a primary filter to filter organic impurities in river water and lake water.
(1)The automatic backwashing irrigation sand filter
The automatic backwashing irrigation sand filter is simple in structure / strong in stability / convenient in installation / stable and reliable. It is made of high-quality metal materials, and can bear higher water pressure with uniform stress.
(2)Laminated irrigation sand filter
The laminated irrigation sand filter is composed of plastic laminations with grooves, which pass water through the channel formed by grooves and intercept impurities to achieve the purpose of filtration.

(3)The centrifugal irrigation sand filter
The larger sand particles are separated and put into the sand collecting tank. After accumulating for a certain time, the sediment will be discharged manually or automatically. The centrifugal irrigation sand filter is suitable for filtering well water, and is often used as the primary filter of well water irrigation filter station.
(4)Net irrigation sand filter
When the water quality is good, the net irrigation sand filter can be used alone. It is generally used as secondary filter, sand filter and centrifugal filter.
(1)Antirust metal appearance: can deal with a variety of environments, durable, anti-corrosion.
(2)The high-quality filter passes through the channel formed by the groove and intercepts impurities to achieve the purpose of filtration.
(3)Fine workmanship, fine product workmanship, stable internal structure, can work for a long time.
The filter is widely used in agricultural irrigation, industrial water, steel industry, electric power, food, parks and other industries.
When the water quality is better: use a mesh filter or a laminated filter alone.
River water and lake water rich in organic impurities: gravel filter + mesh filter / laminated filter when there is sand + centrifugal filter.
Well water rich in sand: centrifugal filter + mesh filter or laminated filter.
