Pile Cloth Disk Filtration Systems


BEACON manufactures proven, long-lasting GDisk® pile cloth disk filtration technology
for wastewater, wet weather, industrial, and potable water treatment.


GDisk® Advantage

Fully-submerged vertical disks with outside-in flow enables increased flow rates, high solids loading, and small footprint.  Static operation requiring power only for backwash minimizes maintenance and electrical costs.  Beacon selects from three GDisk® pile cloth nominal filtration ratings according to the influent characteristics and effluent requirements. Manageable, reasonably-sized disk segments provide for ease of replacement.

How GDisk® Filters Work
Influent water filters through the GDisk® pile cloth, passes from the disk interior to the center tube, and out over an effluent weir.  As solids are captured within the pile, GDisk® automatically backwashes at a set water level or timed interval.  Solids are wasted via the patented GDisk® backwash manifold or tank bottom sludge collector.
Since 2009, GDisk® Pile Cloth Disk Filters reliably remove solids over a broad range of particle sizes and increased hydraulic or solids loading.  Turbidity and concentrations of suspended solids, phosphorus, and other contaminants are all efficiently reduced by GDisk®.  Numerous applications include tertiary, industrial, wet weather, and primary treatment, as well as for phosphorus removal and water reuse.
Phosphorus Removal - Reduction of effluent phosphorus by GDisk® prevents eutrophication, improving receiving waters.

Tertiary - GDisk® provides a superior-performing,
space-saving method to remove suspended solids to meet post-secondary treatment requirements.

Wet Weather - GDisk® filters intermittent, high solids wet weather events with increased sludge and floatable wasting capabilities.

Water Reuse - GDisk® effectively treats reclaimed water as part
of direct or indirect water reuse processes.

Primary - High solids loading rates of the GDisk® enable efficient primary treatment without chemicals under varying influent conditions.

Industrial - GDisk® delivers economical filtration technology to industrial clients to meet pretreatment or direct discharge requirements.
