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

• 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
MSABPTM PROCESS
MSABP COMPLIES WITH GLUMRB STANDARDS
• BOD LOADING PER UNIT VOLUME
• AERATION SYSTEM AND BLOWER SIZING BASED ON STANDARDS FOR BOD and NH3 DEMAND
• PROCESS EFFICIENCY
• 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.
• With the MSABP, there is reduced excess sludge.

Proprietary submerged Proprietary submerged fixed film media is used in fixed film media is used in each stage to provide high each stage to provide high bacteria density and bacteria density and substrate contactsubstrate contact
Media “stabilizes” desired Media “stabilizes” desired organisms to provide high organisms to provide high removal efficiencies with removal efficiencies with negligible net sludge yieldnegligible net sludge yield
MSABP DesignSizing 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
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
Stage 2: Declining Growth
Complex oxidation process begins thereafter with three kinds of reactions– Biomass synthesis– Endogenous respiration– Nitrification-denitrification
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
