Model FD Tubular backwash type micro-clarifying filter
This type of backwashable tubular filter is the most suitable for full automatic clarifying filtration. This system allows complete washing in a few minutes by applying reverse flow of filtrate kept in the top of the filter chamber.
The application ranges of micro-clarifying filtration has been extended to non precoat filtration by selecting filter cloth and clarity, and combinations of precoat equipment and/or dewatering devices.
Features
- Instant filtrate reverse flow mechanism makes high washing efficiency.
- Filter media and filter cloth are easily installed due to the simple tubular structure.
- This system allows simple operation and circulation circuit of
Precoat operation → Filtration → Washing.
Applications
- Plating solutions
- Coolant solutions
- Chemicals
- Saturated salt solution
- Rinse solutions
- Pretreatment process of galvanized coating
- Fluxing solutions
