Mónashell - Superior Performance
•Shells buffer sulfuric acid maintaining
neutral pH
•Treatment of organic sulfur / odor / VOC
compounds
•Can treat airflows with low & high H2S
•Performs on highly variable concentrations
of H2S
•Suitable for intermittent applications
•Eliminates need to have carbon polishing
units behind bio-trickling filters to achieve
odor standards
•High performance without polishing stage
•Rapid acclimation with inoculant at start-up
•No drying out or channelling or clogging
with fines
•Neutral pH water discharge
•EBRT curves to meet the inlet conditions
and performance requirements
•Robust if higher loads than designed or
unexpected compounds are present

Achieving Higher
Efficiency & Performance
•pH – Neutral pH required for enhanced removal of reduced sulfur compounds in a single stage system, self regulating, b ammonia treatment
•Water recirculation – Not tied to controlling pH allows water recirc rate to optimize mass transfer, retention of biology
•High porosity – Air fill porosity value (%V/V) } ~ 70%, increased actual contact time, reduced reactor volume, no short circuiting
•Loading rate – There is not a standard EBRT…loading curves dependent on inlet concentrations, application and performance standard
•Size & shape of the media – Biological growth, mass transfer, height to 10ft
•Biofilm – Maintaining an effective biofilm layer, no biomass clogging
•Optimizing the flow path – Reactors in series, specialization of bacteria for H 2S in 1st stage, sulfur compounds in 2nd stage
•Efficient acclimation & start-up – Inoculation, water recirculation
