Structural Design for Long-Term Anti-Clogging Performance
Technology Philosophy
Clogging is not a maintenance problem.
It is a structural design problem.
Most drip irrigation systems rely on:
• Finer filtration
• Frequent flushing
• Chemical treatment
We take a different approach.
We focus on emitter internal structure,so clogging is addressed inside the emitter,not left to external systems or repeated maintenance.
Designed for Challenging Water Conditions
Our technology is developed specifically for:
• High iron ion and high hardness-water well water
• Sediment-rich sources
• Unstable or untreated water
• Long-term continuous operation
These conditions are common in real agricultural fields, but rarely reflected in laboratory testing environments.
Floating Structure & Self-Flushing Mechanism
At the core of our emitter design is a floating structure.
Floating anti-clogging structure design
Typical drip emitter
Drip irrigation clogging is a "structural problem," not a usage problem. Sewage and self-cleaning are completed inside the drip head, rather than leaving the problem to the outside of the system.
Therefore, the technical design focuses on three core directions:
1. Active sewage discharge structure
2. Balance control of flow rate and sewage discharge
3. Real-time verification of irrigation effectiveness
Floating anti-clogging structure design
The floating structure can shift according to changes in system pressure and flow conditions, forming a high-velocity drainage channel at specific times to effectively discharge sediment and iron particles from inside the drip head.
Technical features
• The floating component triggers the sewage discharge action based on pressure changes.
• The sewage discharge process does not affect the operation of the overall system.
This design gives the drip head continuous self-cleaning capabilities, reducing the likelihood of clogging buildup.
When water enters the dripper, the float-ball is pressed into the gasket, and the flow can only flow out through the small hole. When the water flow stops, the float-ball will rapidly move up and down due to the water pressure difference to expel sewage.
Automatic and manual rapid sewage discharge mechanisms
Pressure compensated drip emitter
Two sewage discharge modes to address different on-site conditions.
Automatic sewage discharge
• Starts when the system starts up and shuts down.
• No human intervention required
• Suitable for removing trace amounts of deposits during daily operation
Manual quick sewage discharge
• Can be activated immediately on-site
• Releases internal blockage in approximately 1 second
• No need to disassemble the drip head
This dual design allows the system to maintain a high degree of controllability even in poor water quality conditions.
When water enters the dripper, the float is pressed against the gasket, allowing the flow to exit only through the labyrinth channel. When the water flow stops, the float moves up and down to expel residue. In case of dripper blockage, the float can be manually pushed upwards to quickly and immediately expel sewage.
Therefore, we do not offer a single design, but rather provide product solutions with different structural orientations based on actual water quality and system conditions to meet the needs of various agricultural applications.
Drip irrigation effect integrated with wireless soil sensor
Make irrigation results "visible"
In addition to the drip irrigation head structure design, we further verified the actual effects of irrigation and fertilization through wireless soil sensing technology.
• Observe changes in soil temperature in real time
• Compare the fertilizer and moisture response before and after irrigation.
• Assists in determining whether the system is operating as expected.
By using sensor data, irrigation management can be transformed from experience-based judgment into an observable and verifiable engineering process.
Technology Summary
Our technology focuses on three core principles:
1. Structural anti-clogging design
2. Application-specific flow management
3. Performance verification through field data
Together, these principles support reliable irrigation
under challenging water conditions.
