How does ultrafiltration operate?

Apr 19, 2018

1. Principle: the separation process of a solution based on the mechanical screening principle is driven by the pressure difference between the two sides of the membrane.

2. Function: remove bacteria, heat source, virus and colloid, protein and macromolecular organic matter in water;

3. Technical parameters:

Water turbidity: <50NTU.

Working pressure: <6bar.

(1 ~ 10)

(4), temperature: 5 ~ 40 ℃

Pressure difference on both sides of the membrane: <2.5bar

Design conditions: see design guidelines.

4. Structure:

External pressure hollow fiber membrane.

5. Operation instructions:

Run 30 ~ 60min.

The water is washed in reverse.


Water and water: 20 seconds.

Water and water: 10S.


Frequency of scrubbing: 1 time / 0.5~2 days.

Water turbidity >15NTU, using the wrong flow filtering method.
