Design of GEM System - Better waste removal than DAF
Click to Enlarge
Unique Design of Primary Wastewater Treatment System
Through aerating 100% of the wastewater under constant flow, the GEM® System creates many more bubbles than a conventional DAF system, to which waste particles of large or nano size (and in between) can attach.

By using a series of liquid solid gas mixing (LSGM) heads (usually 6,) a vortex is created that allows the bubbles to spin at various mixing speeds and energies.

Pressure is dropped in each head under strict control.  This is important in that smaller particles are more apt to attach to particles similar in size – all the way to nano-bubbles.  This means that the GEM System can achieve 99% removal of TSS (total suspended solids) with no carry-over or pin flocs.

Between heads 4-6, polymers are directly injected, under pressure, where they continue through the vortex.  As the polymers enter the LSGM heads, they uncoil, availing more charge sites to attach to more waste particles.  (See Chemistry of the GEM System.) By the time the wastewater enters the flotation tank, the solids and liquids are already separated.  The flotation tank is used only to skim the solids.
