Precautions for the use of titanium sintered porous materials
- During installation, disassembly and clean avoid scratches,
collisions and falls on hard objects.
- Install correctly to avoid reverse filtering.
- Avoid instant pressurization when the filter element works.
- When the filtration efficiency is less than 50%, the filter element
should be cleaned in time.
- When cleaning the filter element, the first backflow with pure gas,
backflow pressure is 1.5 times the working pressure, each time for
3-5 seconds, and 4-6 times, then backwash with clean liquid for 3-5
minutes, repeat 2-3 times.
- If the filter element is not good after online back blowing and
backwashing, it should be removed and cleaned in time.
