High Profile PolyGeyser® Filter

Perfect for Large Volumes of Water Under Pressure

The robust High Profile PolyGeyser can handle high water pressure with finesse.

Introduced in 2015, the High Profile PolyGeyser® Filter (HPPG) is perfect for high volume applications from large aquatic life support systems to wastewater treatment and clarification. Capable of handling large volumes of water under pressure, these PolyGeyser filters gently backwash the media, multiple times a day, to maintain a healthy biofilm. The enhanced nitrification capacity makes this unit ideal for applications with high biofiltration needs.

PolyGeyser filter technology pneumatically backwashes the media regularly, without manual intervention, moving parts, or controllers. This filter provides both mechanical and biological filtration with extremely low water loss by recycling its backwash water and only removing sludge after it has concentrated in the sludge chamber.

This new design pairs the high pressure tolerance and flow rates attained in Propeller Bead® Filter models with the convenience and efficiency of a PolyGeyser. Now you can enjoy the ease of maintenance and save water with a PolyGeyser filter in high pressure applications.

HPPG used for a 45,000 gallon koi pond. Includes pump, filter, and UV system in the configuration.

Filter Benefits:

  • Standard max pressure of 20 psi
  • Inlets and outlets sized for high flow
  • Backwash does not harm the biofilm
  • Mechanical & biofiltration all-in-one
  • Automated backwashing for low maintenance
  • Sludge is highly concentrated for low water loss
  • Air operated, no moving parts for energy efficient operation

How It Works

Treatment Operation

The high profile polygeyser contain a floating bead media that forms a packed bed at the top of the unit.  Water flows into the side of the unit, up through the packed bead bed and discharges from the top of the unit.  The packed bead bed captures suspended solids (TSS) as the water courses up through the unit.  Treated water discharges from the top of the unit.

While the units are excellent for solids capture, they also function as biological filters.  A thin film of bacteria grows on the surface of the media.  The bacteria consume dissolved organic contaminants while simultaneously removing solids.  This allows the units to reduce BOD and TAN (ammonia) concentrations.  They can also be configured to lower nitrogen (TN) concentrations via biological denitrification.

Backflush and Sludge Storage

The High Profile PolyGeyser operates using a rapid automatic air-driven backflush. The backflush frequency is controlled by the rate air is inputted into an internal charge chamber. Backflush air is typically supplied by a small compressor. Actual backflush events occur in a matter of seconds and do not interrupt input flow to the unit.

After backflushing, captured solids settle to the bottom of the unit forming a concentrated sludge. Incoming water fills the unit back up seamlessly resuming normal operation without downtime.

Sludge Removal

Sludge accumulates in the bottom of the unit over multiple backflushes. Periodically, sludge is purged from the units by simply opening a ball valve at the bottom of the unit. This can be done while the unit is still in operation.

The Advantage of Air

The automatic, air-driven backflush makes these very versatile offering a slew of operational advantages and benefits. The speed at the which the backflush is complete allows the units to be backflushed as frequently as the application calls for with no added cost or labor to the operator. As a result, the units can easily be tuned to treat a wide range of TSS concentrations.

The air driven backwash concentrates captured solids minimizing the volume of waste produced. This means less effort and lower disposal costs in comparison to traditional treatment approaches.
