What is the differance between the AlphaOne filter and AquaBead filter?

The bio-media inside!

GCTEK AlphaOne Bio Media

AlphaOne bead filter media.

To answer this we have to understand the difference between bead filters and how they trap solids and how the AlphaONE accomplishes this task. Bead filters trap solids in the first few inches of the bead pac(causing clogging, flow disruption and pressure rises in the vessel) while the AlphaONE with its uniquely designed AlphaBioONEmedia stops the debris evenly through out the pac (resulting in greater flow, less head or back pressure, less maintenance.) The polishing ability of the filter is one it's most desirable features, based upon comments that into us from the field.

The AlphaBioONE media was specially designed for this filter and this filter only. It is not something borrowed from another industry and used in the filter.

Its design is unique in that it was not designed with "cross hairs" as some other specialty types of media use. We left those out because in a static bed the "cross hairs" can collect and hold debris until it becomes anaerobic.

With the AlphaBioONE media there are no hidden areas for anaerobic bacteria, to harbor and stagnate, only beneficial bacteria.

AquaBead Bio Media

AquaBead bead filter media.

Included in all AquaBead(tm) and AquaBead Plus(tm) Systems, we're really excited about these BioGems beads.

As you probably already know, if you have done research on bead filters, the beads float. The more buoyancy that the beads have, the better off we are. To increase buoyancy we have added air to each individual bead during manufacture. Why is this important? Because we want the beads to stay as close as possible to the top of the filter during backwash. We want the beads to stay afloat so they stay away from the outlet slots on the bottom laterals so as not to choke off the laterals preventing the debris from leaving the filter. This was never a problem with the old media, but this new design makes for an even better, more buoyant media.

Besides the air injection technique, we have Dimpled the surface of Bio-Gems, to add more surface and non- abrasion area for the bacteria. This allows for undisturbed colonies of bacteria during backwash, thus creating a bead filter not prone to stumbling after a rigorous backwashing. The size of the bead was slightly downsized, for added surface area, as well.
