Efficient Water-Saving Irrigation Techniques

  1. Sprinkler Irrigation: Sprinkler irrigation saves water by 30% compared to surface irrigation. It is mainly used for densely planted crops in the fields, suitable for localized control, and has advantages such as increased yield and improved land utilization. However, it has higher operational energy consumption, significant evaporation losses, requires large water sources, and can only be used under wind conditions of up to level 3.
  2. Micro Irrigation: Micro irrigation is an advanced water-saving irrigation technology that provides the required water quantity only to the water-demanding parts of the crops, transforming from “watering the land” to “watering the crops.” Micro irrigation is used in facility agriculture and economic crops, adaptable to all terrains and soils. It has the effect of water saving, increased yield, uniform irrigation, and can save water by at least 50% compared to sprinkler irrigation. Micro irrigation facilitates water and fertilizer integration but requires high water quality and regular system maintenance.
  3. Drip Irrigation: Drip irrigation is a recent advancement in irrigation technology. Research and experiments on underground drip irrigation for fruit trees and lawns began in the United States and Australia in 1998, and in cotton fields in Xinjiang, China, in June 2004. Successful trials of underground drip irrigation have been conducted in Beijing, Tianjin, Jiangsu, and Xinjiang, China, since 1996, for fast-growing forests, fruit trees, lawns, and urban green plants. Underground drip irrigation has minimal evaporation, is not affected by wind, and can implement three-dimensional positioning of water and fertilizer irrigation. Its water utilization rate can reach 0.98, with virtually no theoretical water loss. The system has low facility loss, is not affected by UV radiation, and is less prone to aging.

Automatic Backwash Stack Disc Filter System:

  1. High safety performance and durability.
  2. High operational efficiency and easy maintenance.
  3. Large filtration area with low water loss.
  4. Low maintenance costs and strong pressure resistance.
  5. More water and energy-saving.

Filtration Stage:

Water enters the filter and passes through the spiral plate at the bottom of the stack disc, generating a centrifugal effect, causing impurities and particles in the water to stack on the disc. After initial filtration, water enters the filter in the opposite direction for deep filtration. During the backwash stage, water flows through the filter core, causing the stack disc to loosen and undergo backwashing, flushing impurities and particles from the small grooves on the stack disc, which are then discharged through the drain pipe. The stack discs are compressed again to enter the filtration state.
