Shallow Sand Filtration for Agricultural Well Water in the United States
A client in the United States needed a reliable filtration solution for agricultural well water used for farmland irrigation. The main contaminant in the water is fine black manganese sediment. The required flow rate ranges from 50 GPM to 120 GPM (approximately 11.36 to 27.25 m³/h). The recommended filtration system also needed to withstand short-term high startup flow surges, which may exceed 120 GPM.
The client has storage tanks on site. Water flows by gravity to the filtration system and then, depending on the irrigation field, continues through pipelines either horizontally or downward into the fields.
Requirements
- Material: carbon steel with epoxy coating
- Equipped with manual valves, as workers visit the site daily for inspection
- Equipment should be as simple and convenient as possible
- Preferred equipment: Model 24 shallow sand filter
Solution: JX-SL24-3 Shallow Sand Filtration System
After further refinement, the model was finalized as JX-SL24-3, featuring three tank bodies, each with a maximum treatment capacity of 15 m³/h. The client ultimately selected the JX-SL24-3 over the JX-SL24-2.
Technical Specifications
- The system uses Baccara differential pressure controllers and differential pressure sensors.
- The system includes valves, controller, inlet pipe, outlet pipe, filter tanks, clamps, and a base made of channel steel. All components are fully assembled, wired, and connected at the factory. After the equipment arrives on site, only the inlet/outlet pipes and drain pipe need to be connected before operation.
- The main impurity to be filtered is a very fine black manganese sediment. The recommended filtration media is quartz sand or natural sea sand with a particle size of 0.6–1.2 mm. Each tank is filled with 170 kg of media (shallow sand filling height: 400 mm).
- The equipment operates with automatic filtration, automatic backwashing, and continuous cycling.
What We Delivered
Conclusion
The JX-SL24-3 shallow sand filtration system provides a robust, simple, and convenient solution for filtering fine manganese sediment from agricultural well water. With factory-assembled components, automatic filtration and backwashing, and a capacity that accommodates both normal and high startup flow rates, the system meets the customer's requirements for reliable irrigation water filtration with minimal on-site installation and daily maintenance effort.
