Our story
Founded in 2012, Econvert started with a clear purpose: to make the benefits of anaerobic wastewater treatment available to everyone. This goal still drives us today.
We’re driven by a customer-for-life mindset and provide full project support – from design and installation to after-sales services. Our contribution to #MissionWater is to make anaerobic technology available to the widest possible group of users and to help companies meet sustainability goals by lowering their ecological impact. In this way we give water the value it deserves.
Over the years, we’ve grown into a trusted partner for biological wastewater treatment and biogas desulphurization. Our solutions focus on helping industries reuse water locally and lower their environmental impact – because we believe reuse is the future.
We have built a solid track record in key industries like Pulp & Paper, Food & Beverage, Chemical & Pharmaceutical and Waste-to-Energy. Whether we work directly with end-users or alongside project partners, we strongly believe we can serve our customers best by being close and speaking their language.
Our wastewater treatment solutions
We provide solutions for the sustainable purification of your wastewater and for the treatment of the produced biogas in order to realize its optimal value.
Anaerobic wastewater treatment
Anaerobic wastewater treatment is a very effective way of removing biodegradable organic compounds (COD/BOD) from wastewater without the use of oxygen. The degradation of the organic compounds results in the production of biogas, which can be used to generate heat and electricity.
Biogas treatment
Where organic material is anaerobically degraded, biogas will be produced. In order to utilize this biogas it is important that the biogas has the right quality, pressure and humidity. H2S is a specific component in the biogas that can require treatment. With the use of biogas desulphurization technologies H2S is oxidized to elemental sulfur by sulfur-oxidizing bacteria. Biogas desulphurization is a key step in making biogas a clean and reliable energy source.
We offer the following biogas treatment products:
- Biogas buffers: Biogas buffers for stabilizing pressure and flow
- Flares: Standard flares and high temperature flares to burn the biogas when it can’t be utilized
- Biogas blowers/compressors: increasing pressure by means of side channel or roots blowers
- Biogas cooling/drying: Biogas cooling/drying for lowering the dew point and avoiding issues with condensate.
At Econvert we offer various Anaerobic Wastewater treatment and Biogas services, to maximize the performance and reliability of your installation. We provide various types of services: expert services, maintenance & spare parts, service projects. Additionally we can supply consumables and biomass for both anaerobic wastewater treatment plants and biogas desulphurization installations. We value a customer-for-life approach, in which we assist you with optimizing your treatment processes in many ways.

Frequently asked questions (FAQ)
Econvert is the market leader in anaerobic wastewater treatment and anaerobic reactor design (UASB, EGSB, IR/IRC), technology and innovation. In addition, Econvert offers unique biogas desulphurization solutions. It is our goal to make anaerobic technology available to the widest possible group of users to help companies meet sustainability goals by lowering their ecological impact.
We are a leading provider of anaerobic wastewater treatment solutions for a wide range of industries, with a strong focus on Pulp & Paper and Food & Beverage. Our anaerobic reactors are used by recycled paper, tissue, potato, brewery, beverage, sugar, starch, and protein producers.
Other key markets include the Chemical & Pharmaceutical and Waste-to-Energy industries. With extensive experience in treating wastewater from chemical, pharmaceutical and biochemical processes, Econvert demonstrates the versatility of anaerobic technology in treating biodegradable organic substances.
Beyond these key industries, our anaerobic wastewater treatment solutions can also be applied to various other industrial processes, depending on wastewater characteristics and treatment requirements.
Anaerobic wastewater treatment is a very effective and sustainable way of removing biodegradable organic compounds (COD/BOD) from wastewater without using oxygen. Anaerobic treatment uses very little nutrients, requires a small footprint and produces energy instead of consuming energy. By removing COD, anaerobic wastewater treatment allows wastewater discharge or re-use and helps close the water loop in factories. Anaerobic wastewater treatment produces biogas, which is captured and can be used as a renewable energy source. From biogas you can generate electricity, heat, or fuel. It can also be upgraded to natural gas quality biomethane which can be injected directly into the natural gas grid. Anaerobic wastewater treatment reduces the carbon footprint by capturing methane and converting it into energy.
In order to use biogas as a clean and reliable energy source, it needs to be the right quality, pressure and humidity. Biogas desulphurization is the process of removing corrosive hydrogen sulfide (H2S) and other sulphur compounds from raw biogas.
Anaerobic treatment is suitable for wastewater containing biodegradable organic matter, typically measured as Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD). During the anaerobic treatment process, microorganisms break down biodegradable organic components, converting them into biogas while producing a small amount of biomass. With over 200 references worldwide, Econvert has extensive experience treating various types of industrial wastewater. However, every production facility is unique, with different raw materials, production processes, operating conditions, and wastewater characteristics. If you are unsure whether anaerobic treatment is suitable for your wastewater, Econvert offers anaerobic pilot testing to assess its biodegradability.
Econvert delivers anaerobic wastewater treatment and biogas solutions internationally: supporting clients across Europe, North America, South America, Asia, Africa and other regions. If you want to know whether we can deliver/install a solution in your country, please contact us.
