FILTRATION PROCESS

Hydraulic and spring loaded forces compress the retention cap on a stack of thin grooved discs about the center spine.

Process stream fluids laden with suspended solids enter the filter module on a tangent.

Relatively large and dense particulate remains in suspension in the high energy tangential flow.

Fluids permeate through the compressed disc stack while solids become trapped at multiple stopping points within the disc stack matrix.

Trapped particulate creates a filter mat optimizing the removal and loading of finer solids.

Permeate exits the filter for consumption, reuse, or further treatment.

BACKFLUSHING PROCESS

A signal is transmitted by the automatic controller when a specific pressure differential or time interval is reached; repositioning the inlet and outlet valve to backflush mode.

Pressurized "backflush" water hydraulically lifts the retention cap, resulting in the separation and expansion of the disc stack.

Backflush water enters the tubular columns of the spine, then exits through spray nozzles focused tangentially to the curve of the discs, causing them to spin rapidly.

Particulates are flushed from the disc surfaces, restoring the cleaned groove channels.

Backflush volumes of less than 1% of process volume, heavily laden with captured solids are sent to disposal or recovery.

• General Water Inlet
• Fine Duct & Nozzle Protection
• Cooling Towers-Filtration
• Water Recycling & Reuse
• Prefiltration

Suspended solids in inlet water need to be filtered out to the "optimal" filtration grade to ensure uninterrupted downstream process flows.
