The company's flagship anaerobic platform is the BIOPAQ family, led by the BIOPAQ IC internal circulation reactor which handles ten times the loading rate and requires ten times less space than conventional UASB systems, with over 950 references worldwide. Variants include the ICX for next-generation performance, UASBplus for expanded capacity, AFR for anaerobic flotation, and the UBOX, CBD, and RISE configurations. For nitrogen removal, the proprietary ANAMMOX process provides energy-efficient ammonium conversion without organic carbon addition. Phosphorus recovery is handled by PHOSPAQ, while SULFATEQ addresses sulfate removal from industrial streams. Biogas desulfurization is served by the THIOPAQ system achieving up to 99.5 percent hydrogen sulfide removal, alongside THIOKRAFT and THIOTEQ Metal for metal recovery. Aerobic treatment capabilities include the CIRCOX system, with ASTRASAND providing continuous sand filtration and ASTRASEPARATOR handling clarification. Services encompass biomass and biocatalyst supply, laboratory analyses, consultancy, system upgrades, rebuilds, rental installations, and PowerMix nutrient blends. Markets served include beer and beverage, food processing, municipal wastewater, chemical and pharmaceutical, pulp and paper, sugar and ethanol, mining, and bioenergy.
