Odour control forthe 21st Century

Terminodour™

Terminodour system at Tenbury Wells for Severn Trent Water Services

Terminodour™ and the EnvironmentTraditional odour control systemsconsume a significant amount of energyand, in many cases, utilise large quantitiesof chemicals, water and media requiringregular and expensive disposal.Terminodour™ offers a low carbonfootprint solution for odour abatementas power consumption is a fraction oftraditional systems and Terminodour™does not require any chemicals, wateror media.Terminodour™ provides costeffective proven odour control in anenvironmentally beneficial manner.

Terminodour™BackgroundThe first Terminodour system wasinstalled in the UK in 1996 since thenthe process, through a programme ofresearch and development, has becomeone of the most exciting developmentsin the field of odour abatement.Extensive process development has nowresulted in a tried, tested and provensystem that is providing our clients withcost effective odour control andimproved air quality. Our referencesspeak for themselves but we will happilyprovide you with contact details so youcan check our credentials.

The Terminodour™ProcessThe Terminodour™ process combinesventilation and ionisation technologyto provide efficient air distributionwith maximum oxidation capacity todeliver highly effective odour controlwithin a building or any enclosedspace.The Terminodour™ processencompasses a holistic approach toeffective odour abatement and, wherepeople are present, ensures goodinternal air quality.

OperationMost odour control systems extractodour from the point of source andfeed via ductwork to an abatement

system where the odours are eitheroxidised or absorbed before thetreated air is emitted to theatmosphere.The Terminodour™ systemdoes not extract the odour but actuallyoxidises the odour at the point of

source using either the buildingsuperstructure or space beneath thetank cover as the reaction vessel.

Fresh air is drawn by a fan (3) into theTerminodour™ system via an externallouvre (1) and is then filtered (2) toremove particles.The filtered air is thenpassed into the plasma reactionchamber (4) where the hydrogen andoxygen molecules are electricallycharged in a 5:4 ratio (negative/positive).The resulting ions are then distributedaround the building according to thelocation and severity of odour emissionpoints within the building or chamber.

The ductwork system design is anextremely important part of the process

and is a critical element of the design toensure that ions are distributed at theright quantity and rate to meet the levelof odour generation at specific points.

The heart of the Terminodour™ processis the Terminodour™ air handling unit(AHU) that contains the principal systemcomponents; these include the inletfiltration section, fan(s), plasma reactionchamber, ionising modules etc.

Terminodour™ Reaction Terminodour has the capacity to oxidiseall organic odours, efficiency is a functionof contact time and the length of themolecular structure of the molecule tobe oxidised. Hydrogen sulphide is thetrace indicator gas found in wastewaterand given sufficient contact time with theions produced by the Terminodour unitwill be oxidised to a benign, non-toxicsulphate ion.

Terminodour™PerformanceCSO Technik can provide performanceguarantees for odour abatementefficiency on both new build and retrofit

applications. Performance efficiencyvaries according to a number ofparameters however we typically offerodour reductions of 80 -95% within abuilding and up to 99% for storage tankor wet well applications.

Terminodour™ApplicationsTerminodour™ has been proven to beefficient in numerous applicationsincluding :

• Municipal wastewater• Industrial wastewater• GRP or FRP manufacture• Food processing

Terminodour™ Benefits at a Glance• Cost effective odour abatement • Combines odour abatement and

ventilation in one package• Low carbon footprint• No chemicals, water or media disposal

costs• Instantly effective – no start up delay• Can handle variable loadings• Simple non specialist maintenance • Reduces sulphide inspired corrosion • Improves internal air quality• ATEX rated

Terminodour™ Health and SafetyCSO Technik have designed theTerminodour™ system specifically fortreating odours in areas that maypotentially have explosive gassespresent such as wastewater treatmentplants.The system has full ATEXcertification.

Although it is perfectly possible forionisation equipment to produceozone the Terminodour™ designensures that any ozone produced isminimal and far below the occupationalexposure level of 0.1ppm.

Scope of SupplyCSO Technik offer a complete turn-keyservice including: odour surveys, design,manufacture, supply, installation,commissioning, testing and after salesservice. In addition to Terminodour™we are able to offer a wide range ofalternative odour control systems andancillary products such as GRP covers.

Terminodour™ Combination Systems

Odour Abatement - Solutions

In certain applications, specifically whereodour levels are very high,Terminodour™may not be a stand -alone solutionhowever in combination with variousscrubbing systems it can provide a lowercost solution by treating the highvolume/low load odours withTerminodour™ but extracting the lowvolume/high load odours to a separateodour abatement scrubbing system.A typical application would be a sludgecentrifuge building.This provides thefollowing benefits:-

• Smaller scrubbing system – lower capital and running costs

• Much lower power demand due to lower pressure drops

• Reduced footprint• Improved internal

air quality

CSO Technik believe that no singleodour control system is suitable forevery odour problem, consequentlyCSO Technik provides a full range ofodour abatement solutions includingthe following:-

• Biofilters• Bioscrubbers • Dry Chemical Scrubbers • Wet Chemical Scrubbers• Catalytic Iron Filters

CSO Technik provide a complete turnkey project service including supply andinstallation of ancillary equipment suchas control panels, kiosks, ductwork,covers etc.

Specialist VentilationSystemsCSO Technik provide specialistventilation systems for the water,pharmaceutical and general industry, ourexpertise covers:-

• Safe man entry systems• Boiler make up air• Dust extraction• Staircase pressurisation systems• Investigation, testing and reporting on

existing ventilation systems.

CSO Technik provide a wide range ofGRP covers to suit most applicationsincluding rectangular tanks, circular tanks,channels, screw pump covers etc.

Covers can be manufactured to suit awide range of loadings according to need.

Our high security range of covers havedouble seals and are guaranteed not tolift or separate from the structure.The covers are fixed using bolts andembedded nuts to ensure a high qualityseal and that covers can be removedand replaced easily.The high securityrange is specifically for highly sensitivesites or where microbiological hazardsare a concern.

We can also offer a budget range ofcovers with a single seal arrangementwhere the benefits of the high securityrange are not a high priority and price isof paramount importance.
