Product: Sand Filter

Country: Vietnam

Application: Agricultural Irrigation

As a mature, efficient, and economical physical filtration technology, Sand filter, with their superior performance, are becoming an indispensable core equipment for ensuring water quality in modern agricultural irrigation.

Technical Principle: Simple, reliable, and highly effective purification.

The core of sand filters lies in their multi-media physical filtration mechanism. Under pressure, water flows downward through a filter media layer filled with specially graded quartz sand. During this process, impurities such as particulate matter, suspended solids, some algae, and organic debris carried by the water are effectively removed through mechanical screening on the filter media surface and adsorption and retention within the deeper layers of the filter media. The filtration accuracy typically ranges from 20 to 100 microns, sufficient to meet the inlet water quality requirements of most agricultural irrigation systems. This technology requires no chemical agents, operates stably and reliably, and is easy to maintain.

Core Application Scenarios: Wide-ranging coverage and significant benefits.

1. Irrigation of large farmland and orchards.

It is particularly suitable for water sources with high sediment content, such as river water and reservoir water. As a core pre-filtration unit, sand filters effectively remove coarse and medium-sized impurities, providing clear water for subsequent sprinkler, micro-sprinkler, or furrow irrigation systems.

2. Precision irrigation of high-value crops.

For drip or micro-irrigation systems for high-value crops such as vegetables, flowers, and fruits, tiny impurities in the water source can easily clog emitters and micro-sprinklers, leading to uneven irrigation and even system failure. Sand filters are essential pre-treatment barriers for such systems.

3. Utilization of unconventional water sources.

In the context of promoting water-saving agriculture and water recycling, collected rainwater or pre-treated agricultural wastewater often contains high levels of impurities. Sand filters provide cost-effective primary purification of these water sources, improving water quality.

4. Protecting irrigation equipment and extending its service life.

As the first line of defense in irrigation systems, sand filters significantly reduce the wear and tear of hard particles such as silt on pumps, impellers, valves, and pipe walls, as well as the accumulation of soft impurities within the system.

Sand filters are the cornerstone of efficient and stable irrigation systems in modern agriculture. With their proven reliability, superior filtration performance, and economical operating costs, they silently safeguard the purity of every drop of irrigation water, providing a vital foundation for the healthy growth of crops.
