Background
Before fluid analysis, for example, before detecting the content of a certain substance in water, the fluid needs to be pretreated in advance to reduce the turbidity of the water and make the analysis more accurate in order to avoid the interference of a large amount of particles on the detection. The larger particles can be removed by a filter screen, but it is difficult to remove the smaller particles. The use of conventional filtration devices such as (screens, PP filters, stainless steel filters, etc.) requires regular cleaning of the filtration device or replacement of the filter cartridge, which increases maintenance costs during use.
The currently used removal methods mainly include filtration or electrochemical precipitation. These methods are relatively expensive, not suitable for pretreatment of water bodies, and have poor application effects in miniaturization. At present, a fluid device for separating particles, which has low cost, can be miniaturized, has good effect and is free from maintenance, is urgently needed.
