With the growth of industrial water demand, the large-flow filter element also continues to meet the technological innovation. This paper will introduce the latest research direction of large flow filter element.

1. Filtering efficiency is still a research hotspot

Weaving nonwoven fiber: as a new type of composite filter material, it can effectively filter out micronodules and other micronogens and improve the descaling effect.

Multi-layer composite diaphragm structure: using multi-layer different specifications of filter material, graded to improve the filtration efficiency.

New open filter element structure: honeycomb structure can improve the filtration area and reduce the resistance.

2. The level of intelligence will be further improved

Data acquisition sensor: single parameters such as water consumption, water pressure and water temperature. More sensors will be integrated in the future.

Internet of Things capability: In the future, the filter system can realize the control of multi-filter online and adjust the operation strategy according to the real-time operation data.

Mobile APP function: it can realize intelligent early warning, life cycle management and other full monitoring. Provide users with more intuitive information.

3. The process application direction is also being explored

Medical field: to provide super clean water with higher filtration standards for medical devices.

Food industry: to provide high standards of washing water for food processing.

New energy equipment: to provide the booster water for the new energy equipment to meet the special process requirements.

4. Cost pressures are still not significantly reduced

The price of the new composite filter material is still too high.

The initial investment is increased caused by the multi-layer structure.

Intelligent hardware markups still exist.

All of these factors push up costs. The future depends on structural optimization, material technology progress, or relieve some of the pressure.

In general, the research direction of large flow filter element is still to improve the filtration efficiency, and major breakthroughs have been made in structural materials and intelligent level. But the costs are still growing.

Breakthrough progress is slow, but gradually accumulated trend. It is expected that in the next 5-10 years, the filtration effect of large flow filter element will be greatly improved; and the process scope will be more diversified.
