With the rapid development of industry, agricultural planting is more and more limited to the high quality requirements of the surrounding environment, such as air and water quality. Water resources are particularly important for agricultural irrigation. South African customers have planted more than 4000 walnut trees locally and have high requirements for automatic irrigation and fertilization. Customers choose self-cleaning disc filter for peach tree irrigation. Disc filter is a kind of self-cleaning filter. It adopts a number of technologies, which can save water, land and daily maintenance. The filter element has no spring design, and the incoming water pressure is skillfully used to compress the disc group during filtration, which greatly reduces the pressure requirements for backwashing.

Built in duckbill valve ensures the maximum water output of the filter element during filtration, and plays a good check function during backwashing. The core component of the disc filter is the stacked plastic filter disc. There are grooves or edges on the filter disc. The grooves or edges on the adjacent filter disc form a channel with size. The suspended solids with particle size greater than the channel size are intercepted to achieve the filtering effect.

Customers choose laminated filter largely because self cleaning filter can replace traditional mechanical filtering devices such as sand filter, and has superior performance and far lower water and electricity consumption than other products.
