<strong>Geo</strong>-<strong>Reactor</strong><br />
Attached Growth<br />
Moving Bed Biological <strong>Reactor</strong>
<strong>Geo</strong>-<strong>Reactor</strong> Background<br />
• Developed in the US<br />
• First Installation – 1992<br />
• Approximately 50 Installations<br />
• Excellent application in municipal<br />
and industrial markets
Types of Attached<br />
Growth Processes<br />
• Submerged biological filter<br />
– Aerobic or anaerobic<br />
• Rotating Biological Contactor<br />
– Aerobic or anaerobic<br />
• Trickling Filter<br />
– Aerobic only
<strong>Why</strong> Attached Growth?<br />
• More active biomass per ft3 (m3) of<br />
reactor volume than suspended growth<br />
process<br />
– More treatment per unit volume<br />
– Equivalent to 20,000 + mg/l MLSS<br />
– Smaller footprint<br />
• Less sludge produced than conventional<br />
suspended growth processes
<strong>Why</strong> Not Attached<br />
Growth?<br />
• Plugging and clogging<br />
– Leads to mechanical problems<br />
• Odors<br />
– Poor film thickness control<br />
• Limited treatment capability<br />
– Poor nitrification<br />
• Poor mixing and O2 transfer<br />
– Supplemental air added
<strong>Why</strong> Moving Bed<br />
Biological <strong>Reactor</strong><br />
(<strong>MBBR</strong>)?<br />
• Completely eliminates plugging<br />
• Controls film thickness well<br />
• Provides longer contact time<br />
• Complete wetted media surface<br />
• More treatment capability per unit<br />
volume
<strong>Why</strong> <strong>Geo</strong>-<strong>Reactor</strong> <strong>MBBR</strong>?<br />
• Excellent mixing and oxygen transfer<br />
• Excellent contact time<br />
• High quality effluent<br />
– Nitrification<br />
• No supplemental aeration required<br />
• Simple, small footprint plant

<strong>Geo</strong>-<strong>Reactor</strong> Treatment<br />
Aerobic treatment<br />
BOD reduction<br />
Nitrification<br />
(convert ammonia<br />
to nitrite > nitrate)<br />
Anaerobic treatment<br />
De-nitrification<br />
(removal of<br />
nitrogen)<br />
Processes
<strong>Geo</strong>-<strong>Reactor</strong> Features<br />
1. Drag provides mixing & turnover<br />
2. Supplemental air is NOT required<br />
3. Tumbling media<br />
Induces sloughing – keeps bio-<br />
mass active<br />
Eliminates excess weight
4. Moving media bed:<br />
No center dead area<br />
No solids accumulation<br />
No plastic/metal bonds<br />
5. Low energy consumption<br />
6. Operator friendly<br />
7. Low maintenance costs

Competitive Advantage<br />
2-3 times treatment capacity<br />
Retrofits existing RBC footprints<br />
Competitive capital costs<br />
1/3 operational costs of other<br />
systems<br />
Ease of operation
Frequent WWTP Dilemma<br />
Aging RBCs<br />
Broken RBCs<br />
No space to<br />
expand<br />
Too costly to<br />
abandon RBCs<br />
High maintenance
RBC self destructing
Replacement of RBC<br />
<strong>Geo</strong>-<strong>Reactor</strong><br />
directly replaces<br />
existing RBC’s<br />
No adjustments<br />
to tank.
Component Systems<br />
Individual<br />
component design<br />
Flexibility is built<br />
into the system<br />
Typical Uses:<br />
Nursing Homes,<br />
Roadside Rests<br />
Larger Subdivisions
Small footprint<br />
Minimal noise<br />
