Wastewater, Effluent & Anaerobic Digestion

Sirona helps wastewater, effluent and anaerobic digestion operators improve process performance across biological treatment, aeration, sludge, FOG, odour and biogas systems. Our activation technologies support better gas-liquid interaction, cleaner process behaviour and more stable treatment outcomes — helping sites reduce operating pressure, chemical demand and energy waste.

Oxygen availability sits at the heart of many wastewater and effluent treatment processes. Activation technology supports improved gas-liquid interaction. Oxygen becomes more available within the treatment environment and supporting the biological activity needed to break down pollutants.

E-Acti’Water+ has been shown to naturally increase oxygen levels in wastewater treatment

Aeration and mixing are often among the largest energy demands on wastewater and effluent treatment sites. By improving oxygen transfer and treatment stability, Sirona can help reduce the operating requirements on aerators, blowers, mixers and circulation systems while maintaining treatment performance.

E-Acti’Water+ has been shown to improve the performance of the treatment and reduce the energy-intensive aeration 25-40%.

FOG, foam, floating matter, sludge build-up and pipe blockages can create major operational problems in municipal and industrial treatment systems. Sirona can help support more stable process behaviour, reducing the conditions that lead to persistent foaming, clogging, floating mass and maintenance-heavy treatment issues.

Many treatment sites rely on chemicals to manage odour, phosphorus, pH, foam, FOG, sludge or biological imbalance. Where process stability improves, sites are able to reduce chemical reliance while maintaining or improving treatment outcomes.

Treatment performance ultimately depends on output quality. Sirona can support biological and process conditions that help improve pollutant breakdown, suspended solids behaviour and overall discharge quality across suitable wastewater and effluent systems.

Our technology can reduce nitrogen (NGL) levels by 30% and phosphorus levels by 34%. We deliver a higher quality treated wastewater, minimising environmental impact.

Odour issues can affect staff, neighbours, compliance pressure and site perception. E-Acti’Water+ will neutralise foul-smelling odours from your treatment plant, creating a more pleasant working environment for your team and a better experience for surrounding communities

Some treatment plants reach capacity because oxygen transfer, sludge behaviour, FOG, blockages or process instability limit what the existing system can handle. By improving treatment conditions, Sirona may help sites get more useful performance from existing tanks, aeration systems, pipework and biological processes before major capital upgrades are considered.

Anaerobic digestion plant

Anaerobic digestion depends on stable biological activity, digestate behaviour and gas production conditions. Sirona’s activation technologies can support AD operators by:

  • Helping reduce foam and crust formation
  • Improving process stability
  • Increasing biomethane or biogas production in suitable systems.

Sirona is relevant where wastewater, effluent or biological treatment systems are affected by oxygen limitations, energy demand, FOG, foam, sludge, odour, chemical use, discharge quality, blockages or capacity pressure.

  • Typical applications include:
  • Municipal wastewater treatment plants
  • Industrial effluent treatment plants
  • Food and beverage wastewater
  • Dairy and textile effluent
  • DAF and FOG-heavy systems
  • Aeration basins
  • Clarifiers
  • Anaerobic digesters, biogas plants and digestate handling systems.
