3. What is MSABP?
Attached growth biological wastewater treatment process
Multiple biological selectors in series
Produces environment for the creation of naturally occurring microbial
food chains
Whereby the organisms that reduce the organics are in turn
consumed by higher level organisms, termed “vulture filtrators”, and
removed from the flow train.
Effectively eliminates pollutants in wastewater
Does so without the generation of waste sludge (biosolids) common in
other biological processes
Results in substantial capital and operation cost savings
6. • Custom designed process with pretreatment consisting of fine screening, and
grit removal
• Removal of inerts creates the required environment for the MSABPTM
reactor
• Process is based on spatial microorganism successions and trophic chains
• Provides for conditions in which organics are consumed by primary
microorganisms while the primary organisms are later consumed by higher
order predatory microbes.
• Process utilizes naturally occurring microbial food chains to reduce excess
sludge

8. • The MSABP is an attached growth
process based on selector technology and
the creation of microbial food chains, where
the organisms that reduce the organics are
in turn consumed by higher level organisms,
termed predatory microbes, and removed
from the flow train.
• The hyper plug flow scheme and attached
growth technology produces a high quality
effluent in a simple, easy to operate
package.

24. MSABP Design
Sizing Criteria
Based on flow, 16-24 hours hydraulic retention time
– Dependent on level of treatment required
– Longer HRT for higher efficiency treatment
Based on BOD5 loading < 40 #/d/kcf at 8-10°C
– Municipal typically < 15 #/d/kcf at 8-10°C
8-12 stages
– Dependent on level of treatment required
25. Stage 1: Logarithmic Growth
Absorption of dissolved organics by
organisms on the fixed growth media
Logarithmic biomass growth in a short period
of time
Carbon adsorption relative to mass of
microorganisms and oxygen
Significant BOD5 reduction in this phase
26. Stage 2: Declining Growth
Complex oxidation process begins
thereafter with three kinds of reactions
– Biomass synthesis
– Endogenous respiration
– Nitrification-denitrification
27. Stage 3: Endogenous Phase
Oxygen demand decreases in later stages of
the process
Microorganisms are assimilated by higher
order organisms in the food chain
Massive destruction of sludge mass occurs
Process minimizes the “sludge” remaining in
the effluent with the only “sludge” leaving the
system is the TSS meeting permitted limits
