Voin, a global food company based in the Netherlands, has selected Colsen to build a wastewater treatment plant at the food company’s Boxtel location.
The companies expect the installation to be operational by the end of the year. Hydrobusiness will operate the plant.
Colsen’s technology can halve energy costs compared to conventional activated sludge technology and will allow Voin to reuse 25 percent of its wastewater, DutchWaterSector.com reports.
The plant works like this: The wastewater from the production passes a fat separator before anaerobic digestion is applied to transform biomass into biogas. Colsen’s Bidox system then biologically desulphurized the biogas produced. This gas treatment system reduces the amount of H2S in biogas to levels below 50 ppm.
Vion will be able to use the renewable energy produced to power its manufacturing facility.
The next step further treats the wastewater using aerobic treatment. Colsen’s MBR-NAS system, which uses anammox bacteria removes nitrogen during aerobic purification, allowing Voin to reuse water in its production process.
MBR stands for membrane bioreactor and NAS stands for new activated sludge.
Low-energy, low-sludge systems lead paradigm change in wastewater, according to a Lux Research study published last month. An important development poised to go mainstream is low-energy, low-sludge wastewater treatment, the report says.
