The coalescence separation filter element is used in the oil-water separation system, mainly separating oil-water mixture, suspension solution, emulsion

solution, etc.

In the system, the use process of coalescence separation filter element is solid-liquid separation--- demulsification--- coalescence--- separation ---

 adsorption; It has the advantages of large dirt holding capacity, high flow density and long service life, and can meet the needs of various fine filters.

First, the working principle

When the filter medium flows into the coalescence filter element, the impurity removal layer of the coalescing filter element performs high-precision

 filtration of 1~25μm on the medium, and then enters the coalescing layer. The coalescence layer expands and coalesces the water molecules in the 

medium to form larger water droplets, and with the action of gravity falling off, some water droplets further flow to the filter outlet due to the 

influence of flow rate, and then an oil-water separation filter element is required for separation and dehydration.

Coalescing filter element

The separation filter element is made of Teflon hydrophobic material, and when the oil passes through the separation element, the water droplets are

 blocked from the outside of the separation filter element, while the oil can pass through and be discharged from the outlet.

Second, product features

1. Multi-layer filter material: The coalescence separation filter element is usually composed of multi-layer filter material, and each layer of filter 

material has different filtration effects. This multi-layer structure can filter layer by layer and improve filtration efficiency.

2. Large pore size filter material: The outer layer of the coalescence separation filter element usually adopts large pore size filter material to capture 

larger aggregates. This design reduces the resistance of the filter element and extends the service life.

3. Small pore size filter material: The inner layer of the coalescence separation filter element usually uses small pore size filter material to capture 

smaller agglomerates. This further improves the filtration accuracy and ensures the purity of the water quality.

4. High-strength material: The coalescence separation filter element is usually made of high-strength material and has good pressure resistance. This

 ensures that the filter element works properly under high flow and high pressure conditions.
