With the development of social economy and filtration technology, the field of agricultural irrigation has ushered in a new opportunity, the operation of the filter is more convenient, and it improves crop yield and increases revenue.
Irrigation system can not be realized without the normal operation of the various irrigation equipment, the choice of the right filter is a prerequisite for the success of the irrigation project, there are differences between the different types of filters.
Q: What type of filtration equipment is used to filter groundwater?
A: Hydraulically driven filters are preferred over laminated filters. Stacked filters, hydrodynamic filters, and gravel filters can be used alone when water quality is good.
Q: What kind of filtration equipment is used for secondary filtration of surface water?
A: Stacked filters are preferred over hydrodynamic filters. For water containing a lot of organic pollutants, use gravel filters (multi-media filters).
Q: What kind of filtration equipment is used for water with high content?
A: Centrifugal filters are used for water with high content, in conjunction with screen filters. The selection of the filter pore size depends on the type of equipment used and the size of the flow channel cross section.
Generally speaking:
Sprinkler irrigation requires 40-80 mesh filtration.
Micro-sprinkler requires 80-100 mesh filtration.
Drip irrigation requires 100-150 mesh filtration.

Sand and gravel filter
One-stage filtration, utilizing the three-dimensional filtration of sand bed, effectively treating impurities in water, applicable to water quality where the water source is surface water or the content of organic matter in water is more than 10 mg/L.
✔ High filtration speed and low pressure loss
✔Automatic backwashing, realizing uninterrupted water supply
✔ Modularized setting, small footprint, low investment
✔ According to the irrigation project dosage and filtration requirements, it can be used individually or in multiple combinations
Stacked Filter
As the secondary filtration of irrigation water, it effectively removes the fibrous impurities in irrigation water, and especially has high capturing ability for soft impurities and fibrous impurities.
✔Full-automatic backwashing
✔High filtration precision, small footprint, very easy to assemble
✔ Filtration of multiple impurities, including inorganic impurities (sand, sediment, etc.), organic impurities (seeds, floating matter, etc.)
Hydrodynamic drive filter
Single-stage filtration, using stainless steel filter, mainly used for filtering impurities, sand and scale and other dirt in irrigation water, also can be used for filtering irrigation water containing a small amount of organic dirt, applicable to irrigation water systems with flow rates of 10m/h-200m/h.
✔Full-automatic intelligent control
✔With automatic backwashing function
✔ Relying on the water pressure in the system, no external power required
Centrifugal filter
As the coarse filtration of groundwater, deep well water and surface water with large sand content, it removes large granular impurities, and the sand removal rate is as high as 99%.
✔ Simple structure, low cost
✔Easy to install and operate, no need for a lot of manual maintenance
✔Small size, large water treatment capacity, save installation space
