Mesh Grid
The Hydro-Flo™ Screen

Patented Stainless Steel Mesh Grid

The Hydro-Flo Screen is available in both Mesh and Link style grid. The Mesh style grid is ideally suited for water and wastewater applications where ultra-fine screening is required. Stainless steel frame, hook links and axles support even the finest of meshes in the harshest of environments. Unlike perforated stainless or molded plastic panels, the supported mesh frames are able to filter down to 1mm or less openings with extremely high open area percentages. This results in lower velocities through the grid and filtration of higher flows. Easy access to the panels allows for simple cleaning and removal if required. The Mesh style grid is often selected by design engineers for protection of sensitive processes such as Membrane Bioreactor (MBR) Plants.

The image on the left is of the hook links from the inside of the screen. These hooks lift the large solids from the flow while the tray shown on the right removes the finer solids that may fall between the hooks. The mesh grid is made up of alternating rows of hooks and trays for optimal solids removal.
