Souvan itilize filtè pou sistèm irigasyon yo


Enpurte òganik ak inòganik nan sous dlo nan sistèm irigasyon an ka bloke irigatè a oswa afekte operasyon nòmal irigatè a. Nan konsepsyon sistèm irigasyon an, yo ta dwe konsidere bon jan kalite dlo nan sous dlo a, epi apwopriyefiltre should be selected to effectively remove the impurities in the water body. Pay attention to the maintenance and maintenance of the filtre during use to make it function normally.


At present, the commonly used filtres mainly include: centrifugal filtre, sand filtre, mesh filtre and laminated filtre.


1. Centrifugal filtre

Centrifugal filtre (sand and gravel separation filtre) mainly uses the working principle of water circulation centrifugal force to separate sand particles in water, and is suitable for primary filtration of water sources with large sand content.


2. Sandfiltre

It mainly uses sand and gravel as the filtre material to filtre. During normal filtration, all units of the filtre are normally filtreed. During backwashing, one unit is backwashed at a time, and the remaining units are normally filtreed. Whether it is organic or inorganic impurities, gravel filtres are the most ideal filtreing method.


Third, the mesh filtre

May lafiltre is the most common filtre, which directly intercepts impurities in the irrigation water source. Its structure is simple, generally composed of a pressure-bearing shell and an inner filtre screen; the pressure-bearing shell is mostly made of steel, and the inner core filtre has a stainless steel mesh, a nylon mesh, etc.


Kat, laminated filtre

The laminated filtre adopts a modular design, and the number of filtre combination units can be selected according to the system flow. It is flexible and changeable and has strong interchangeability. The large flow lamination filtre station is composed of multiple units. Stacked filtres are often used in secondary filtration, combined with sand filtres and centrifugal filtres.
