Since 2008, more than 250 GDisk® pile cloth media filter installations operate around the world. The largest GDisk® installation in Gwangju, Republic of Korea, delivers an impressive filtration capacity of 160 MGD. Four model types provide unit capacities* from 13.2 MGD down to 0.04 MGD each. *Typical HLR using GDisk® standard media
Beacon selects from three GDisk® pile cloth nominal filtration ratings (Standard – 10 µm, Fine – 5 µm, and Ultra – 2 µm) according to the influent characteristics and effluent requirements. Contact Beacon for application assistance.
How It Works
Influent water filters through the DuraPile™ 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.
Fully-submerged vertical disks with outside-in flow enable 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 DuraPile™ cloth nominal filtration ratings (Standard – 10 µm, Fine – 5 µm, and Ultra – 2 µm) according to the influent characteristics and effluent requirements. Manageable, reasonably-sized disk segments (8, 6, or 4 per disk – model dependent) provide for ease of replacement.
GDisk® DuraPile™ cloths are thermally‐fused between the support layer and the pile cloth—no chemical adhesive is utilized. Media backing contains strong monofilaments in the longitude direction to strengthen the rotating durability and equalize filtration rating. Cloths are manufactured of environmentally friendly, high temperature rated (100 – 150 ℃) polyester, not acrylic.
