Central-flow Fine Screens

Waste water enters the centre of the fine screen and flows outwards through the panels of two sides.  The removal rate of trash can be up to 95%, eliminating the carry-over and by-pass problems.
Description

Waste water enters the centre of the fine screen and flows outwards through the panels of two sides.  The removal rate of trash can be up to 95%, eliminating the carry-over and by-pass problems.
