Comments on Selection of Technology

This technology was developed for high levels of H₂S and VOC’s

Comments on Life Cycle Cost

Long life cycle costs even for high VOC and  H₂S emissions when benchmarked against chemical scrubbers activated carbon and thermal oxidisers

MÓNASHELL® BIOFILTRATION BENEFITS
OVER OTHER BIOFILTERS

Treats high and variable concentrations of H2S 
and a broader range of organic sulphides

Up to 67% footprint reduction compared to conventional biofilters due to higher efficiencies, reduced contact time, and deeper filter bed

No short circuiting or channelling through media

High porosity, low pressure drop, low energy requirement

Lower water consumption: 
water recirculation conserves H2O

No nutrient addition

OVER CARBON AND WET SCRUBBERS

Low pressure drop, low energy costs

Lower media replacement costs

Eliminates need for chemicals

Sustainable process uses naturally occurring recovered media

Effective on highly variable inlet conditions

Lower operating and maintenance costs

OVER RTO

Low energy

Low CO2  footprint

Able to treat high variable concentration of VOC
