Econvert-RTF®: Regenerative Trickling Filter - Anaerobic Treatment

Your challenges

Presence of H2S in biogas

H₂S is a component in biogas that requires treatment, before the biogas can be utilized as an energy source. Econvert-RTF® achieves a 99% H₂S removal rate, and allows the biogas to be re-used directly or with additional polishing with activated carbon filters depending on end-user needs.

Sustainability and carbon footprint goals

There is pressure for companies to become more sustainable and to achieve certain sustainability goals. Econvert-RTF® ensures that energy recovered is not only renewable but also enables to burn the biogas in a correct way without harmful sulfur emissions.

Rising energy costs

Energy costs are continuously increasing, and there is pressure to adopt renewable energy. Econvert-RTF® treats biogas and ensures the biogas has the right quality, pressure and humidity for re-use. The reliable performance and non-clogging set-up enables a high uptime and high energy recovery availability.

Our Solutions brochure

The process

The Econvert-RTF® is a regenerative trickling filter designed for biogas desulfurization. It consists of a filter bed in which hydrogen sulfide is removed from the biogas through biological oxidation. Depending on the selected process conditions, the system can be steered towards either elemental sulfur or sulfuric acid production. The key innovation of the Econvert-RTF® is its ability to regenerate (i.e. ‘wash’) the filter bed material. Regular decommissioning of the desulfurization installation to clean the filter bed is no longer necessary, since solids accumulation is prevented by automatic recirculation of the filter bed material. Aerobic effluent can be reused as suppletion water (if available), minimizing (potable) water consumption.

Our positive impact

The reliable biological solution without chemicals

>99% H2S removal efficiency

H₂S removal rates of over 99% can be achieved. Due to the high H₂S removal rates, the biogas can be reused directly or only needs minor additional polishing with activated carbon filters depending on end-user requirements.

Low operational costs

Due to the regeneration of the alkalinity in the bioreactor the operational costs are low. Compared to chemical systems where no alkalinity is regenerated, the amount of caustic consumption can be up to 20 times less.

No clogging

Clogging in the Econvert-RTF® is prevented by its built-in cleaning system. During operation the installation can be put in cleaning mode without any negative effects on the ongoing biogas treatment.

Continuous operation

The Econvert- RTF® can be operated continuously, without regular time-consuming and extensive maintenance work.
