Recirculating Biotrickling Filter (BTF)

 Hydrogen sulphide (H2S) is the well known major foul air contaminant, and Aquatec’s range of tailored BTFs are purpose-built to reducing H2S by over 99% (or down to 0.1ppm). This world class technology provides the best long-term return on investment (ROI) due to the long-life engineered open-cell foam media and recirculation design, which responds exceptionally well variations in odour inlet concentrations.

The BTF utilises random packed media that is continually recirculated to maintain a humid environment that has a consistent pH range and irrigation enabling the propagation of resilient autotrophic biomass that ensures a healthy operating environment. Aquatec’s inhouse engineering team designs and builds systems to meet our clients’ specific requirements on an individual project basis, delivering value adding, cost effective and efficient treatment solutions.

Key Benefits of choosing Aquatec’s BTF:

  • Biological fixed film oxidation reactors using a continually wetted matrix
  • Two-stage process of absorption/solubilization, followed by oxidation (biological)
  • A cost effective and efficient treatment of H2S achieving a 99% or greater removal
  • Smaller footprints • Responds well to variations in H2S concentrations
  • Best selected for applications that have H2S as the major cause of the odour constituent
  • RE (secondary/tertiary) or Potable Water compatible

Biogas Sweetening

Biogas emissions provide a valuable potential source of recoverable energy. However the presence of (H2S) in biogas can restrict its use as it will adversely impact downstream equipment and cause SOx emissions in thermal combustion of the gas. In addition, the presence of H2S can lead to issues with health and safety as well as cause a potential off-site nuisance condition for the community. Aquatec offers an array of biological trickling filters designed to handle any biogas flow and H2S content. Contact us for more information.

BioFilters (BF)

Designed for a more complex range of odour types, the Aquatec BF is most suited for large infrastructure sewerage pumping stations through to medium to large wastewater treatment plants, where the predominate source of odour is other than Hydrogen sulphide (H2S).

Aquatec’s range of tailored BF are designed and built to meet specific requirements of each project, providing cost effective and efficient treatment and reduction of a full range of more complex (non-H2S) odours coming from industry, residential and those created from the collection system itself.

Using patented world class engineered inorganic media with a 20-year design life, this technology provides the ultimate in the combination of total odour removal and whole of life costs. The BF utilises random packed engineered inorganic media that is intermittently irrigated with neutral pH secondary/tertiary effluent or potable water to maintain an environment conducive with the propagation of resilient heterotrophic biomass to remove a wider variety of foul air contaminants along with lower levels of H2S.

Key Benefits of choosing Aquatec’s BTF:

  • Biological fixed film oxidation reactors using
    a continually wetted matrix
  • Two-stage process of absorption/solubilization,
    followed by oxidation (biological)
  • Engineered inorganic medias provide the following performance benefits:
  • Reduced maintenance intervals and superior performance
  • Permanent/Non-degrade
  • Low Energy Consumption
  • Specific Surface Properties
  • High Available Surface Area
  • Predictable Performance
  • Low Background Odour
  • Very robust to changing inlet conditions.
  • 20 year plus expected media life
  • Lower EBRT’s reduces overall footprint.
  • Biofilters are the simplest systems to operate out of all the odour control technologies.
  • They also require the least amount of maintenance (lack of moving parts).
  • Biofilters require the largest amount of space of any odour control technology.
  • Initial capital expense can be higher than other technologies
  • Operating costs are the lowest of any technology (engineered medias)
  • Select this technology for demanding odour applications; reliability; unmanned facilities; total odour removal

Aquatec’s odour control units are customised to deliver effective solutions to mitigate a variety of odour and emission situations.

Foul air enters the bottom of the filter, passes upwards through a wet media and exits as clean air.

An advanced spray system continuously humidifies the media to cultivate a healthy biological activity.

System includes pump, nutrient addition and sump that continuously recirculates an acidic liquor to maintain optimum reduction in odour.

A variety of proprietary media capable of providing treatment solutions to a wide range of applications.

Activated Carbon

Designed for low odour applications or for polishing at the end of a biological treatment train, Aquatec’s range of custom-built ACUs provide such process stream flexibility across the spectrum of wastewater applications from network pump stations to treatment plants.

Aquatec’s range of tailored ACUs are designed and built to meet such specific project requirements, providing cost effective and efficient treatment whilst reducing all types of foul air contaminants. Configured to suit individual requirements, our ACUs simplify the operational and work health and safety over the life of the unit. Aquatec provides a comprehensive range of carbon varieties, to best treat each type and concentration of odour.

Key Benefits of choosing Aquatec’s ACU:

  • Can be used for a broad spectrum of odours.
  • Uses shorter contact times (usually between three and six seconds) Smaller footprints
  • Good for small / internment flows or low contaminants concentrations
  • Excellent as a main process treatment option for non-H2S foul air contaminants
  • Suitable for “polishing” residual foul air contaminants post-other treatment technologies
  • Quick change over cartridge replacement system

Foul Air and Emissions Modelling

Complementing our end-to-end solution capability, Aquatec provides specialist consulting services aimed at furnishing asset owners with odour control and air treatment options that are data driven and comprehensively defined to ensure that asset owner key drivers are being met. This is achieved by:

  • Foul air characterization studies utilising soſtware packages such as Calpuff.
  • Air dispersion modelling on treated air emissions to eliminate nuisance foul air.
  • Enhance asset owner reputations in their local communities by preventing complaints.

Chemical Dosing

Aquatec’s range of chemical-based odour control technologies include the use of Magnesium Hydroxide Liquid, Ferrous and Ferric Chloride as well as other chemicals. These solutions are able to reduce unpleasant, corrosive odours and gases while extending the life of wastewater assets and infrastructure.

Magnesium Hydroxide (MHL)

Magnesium hydroxide, or MHL, is one of the most common chemicals used for dosing into wastewater streams. Designed for dosing directly into pump stations and rising mains where there are long detention times, MHL dosing systems control the acidity, or pH, of the wastewater to prevent the transfer of Hydrogen Sulphide from liquid form into airborne gas particles, both at the source and the discharge end of long rising mains.

 

Key benefits:

  • MHL is safe to handle
  • Commonly administered through the sewer manhole, pump station or rising main
  • Activity of biofilm is also inhibited under the elevated pH conditions, reducing the overall Sulphide production

Iron Salts

Dosed directly into a sewer stream, iron salts are a proven technology for long-duration Sulphide control, offering improvement in chemical phosphorus removal.

Designed for applying directly into pump stations and rising mains where there are long detention times, iron reacts with dissolved Sulphides to form Sulphide precipitates, locking the Sulphide into an insoluble form. This reduces the release of Hydrogen Sulphide into the sewer headspace.

Key benefits

  • Iron salts inhibit biofilm activity and can be applied directly into the sewer stream at a manhole or rising main
  • Ferric substances are available at lower cost per tonne than other chemicals
  • Does not ‘settle out’ inside the sewer infrastructure

OdoZone

By creating oxygen and ozone as required, the system holistically treats the cause of odours.This saves time, avoids public complaints, maximises cost savings and removes the risks associated with using chemicals.
