Anox Kaldnes product offering
Product offeringCore offering
AnoxKaldnes designs, supplies, and supports biological wastewater treatment systems built around its proprietary Moving Bed Biofilm Reactor (MBBR) technology. Its offerings include a family of MBBR-based products (AnoxKaldnes MBBR, Cella, ANITA Mox, Anoxthane, BAS, Biostyr Duo, eXeno, Hybas, Tracer, Z-MBBR) that use plastic biofilm carriers for municipal and industrial water purification. The company complements these products with accredited laboratory testing, on-site pilot rentals, specialist process support contracts, and operator/engineer training, delivered globally via the Veolia Water Technologies network.
Product overview
Anox Kaldnes is a world-leading provider of biological water purification solutions for industries and municipalities, offering a comprehensive portfolio of MBBR-based technologies and related services. The core technology platform centers on Moving Bed Biofilm Reactor (MBBR) systems, with specialized variants including Cella™ (renewable biomass biofilm), ANITA™ Mox (deammonification), Anoxthane™ (anaerobic), Hybas™ (IFAS hybrid), Z-MBBR (controlled biofilm thickness), Tracer™ (complex compounds), and Biostyr™ Duo (combined BAF-MBBR). Supporting services include laboratory testing, pilot studies, education/training, and specialist process support across municipal and industrial applications.

Functional benefit
Products and services
- Cella™ Breakthrough biofilm technology leveraging MBBR principles with a new support material made from renewable biomass. All-in-one biological solution for treatment of carbon, nitrogen, and phosphorus with minimal energy consumption and compact footprint, applicable to municipal wastewater treatment.
- ANITA™ Mox Single-stage deammonification process based on MBBR technology that removes more than 90% of ammonia and 75-85% of total nitrogen through partial nitritation/anammox, without external carbon source and with reduced air requirements (up to 60% lower oxygen demand vs. conventional nitrification-denitrification).
- Anoxthane™ Anaerobic MBBR technology enabling treatment of wastewater with varying COD and TSS levels. Uses AnoxK™Z carriers with controlled anaerobic biofilm growth for robust, temperature-tolerant biological treatment.
- BAS™ Biofilm Activated Sludge process combining MBBR and conventional activated sludge in an optimized configuration. Protects and enhances biological treatment by reducing organic material, minimizing sludge production, and improving settling properties.
- Biostyr™ Duo Combination of aerated biological filter (BAF) and MBBR technologies. Achieves simultaneous biological treatment and suspended solids removal in one step with the most compact footprint for carbon and nitrogen removal.
- eXeno™ MBBR-based biological wastewater treatment technology for removing micropollutants such as pharmaceuticals and industrial chemicals. Enables longer sludge retention time so slow-growing microorganisms can break down difficult compounds.
- Hybas™ IFAS (Integrated Fixed Film Activated Sludge) solution combining MBBR carriers with activated sludge for compact organic material and nitrogen removal. Enables cost-effective upgrade of existing activated sludge processes.
- AnoxKaldnes™ MBBR Moving Bed Biofilm Reactor technology where biofilm grows on suspended carriers. Compact and robust biological wastewater treatment used across municipal and industrial markets for aerobic, anoxic, and anaerobic processes.
- Tracer™ Family of specialized MBBR solutions for biological treatment of complex compounds in industrial wastewater, including glycols, cyanides, and selenium. Removes harmful substances that are difficult to treat biologically.
- Z-MBBR MBBR carriers with controlled biofilm thickness using AnoxK™Z-200 and AnoxK™Z-400 carriers. Enables predefined biofilm thickness of 200 and 400 µm respectively for specialized applications requiring high stability and performance.
- Laboratory Services Accredited laboratory services including biological batch tests, continuous bench-scale simulations, and microbial diagnostics for developing, optimizing, and troubleshooting biological wastewater treatment processes.
- Pilot Tests On-site performance testing demonstrating process and equipment performance at customer installations. Includes pilot equipment rental with startup assistance and remote process monitoring support.
- Education and Training Courses in microbiology and wastewater treatment for operators and engineers, including basic and advanced levels, customized on-site training, and microscope-based biological troubleshooting courses (e.g., Basic Microbiology course priced at 23,500 SEK per participant).
- Specialist Process Support Expert support for troubleshooting and optimization of biological treatment processes, including operational data evaluation, extended analysis programs, diagnostic microscopy, and biological batch testing, delivered via service contracts for MBBR facilities.

Anox Kaldnes competitors and assessment
Company assessmentDirect peers
- Ovivo: Canadian-headquartered designer and supplier of water and wastewater treatment systems, including biological and membrane solutions for municipal and industrial customers. Overlaps with AnoxKaldnes on biological process equipment and project delivery to utilities and industries.
- Paques: Dutch biotechnology company providing biological water and gas treatment systems, including ANAMMOX-based and biofilm reactor solutions for municipal and industrial customers. Shares the high-end biological wastewater treatment niche with AnoxKaldnes.
- Aqua-Aerobic Systems: US-based manufacturer of biological and cloth-media filtration systems for municipal and industrial wastewater, including aerobic and anoxic treatment processes. Directly competes with AnoxKaldnes on biological treatment solutions, particularly in North American tenders.
- Organica Water: Hungarian-origin specialist in fixed-film biological wastewater treatment, including MBBR and IFAS variants, plus food-chain bioreactors. Competes head-to-head with AnoxKaldnes for municipal and industrial biofilm retrofit projects globally.
Broad incumbents
- Xylem: Global water technology major offering biological treatment (Sanitaire), advanced aeration, and MBR/MF systems via its Xylem and Evoqua portfolios. Competes broadly with AnoxKaldnes for municipal and industrial wastewater tenders, though without AnoxKaldnes' pure-play MBBR specialization.
- Veolia Environnement: Parent group and broader environmental-services competitor. Beyond AnoxKaldnes' specialty MBBR niche, Veolia operates large-scale municipal concessions and competing in-house biological treatment technologies, shaping the competitive context and channel access for AnoxKaldnes.
- SUEZ Water Technologies & Solutions: France-based water services and technology incumbent operating municipal and industrial water/wastewater treatment assets and supplying treatment systems. Overlaps with AnoxKaldnes on biological treatment and project execution, though much broader in scope and footprint.
- Degrémont (SUEZ): SUEZ's water-treatment engineering brand building municipal and industrial treatment plants, including biological and tertiary nutrient-removal stages. Competes for the same large municipal EPC tenders that AnoxKaldnes targets via Käppala-style projects.
Emerging players
- Fluence Corporation: Provider of decentralized and packaged water and wastewater treatment plants using MBR and biological technologies. Targets small-to-mid municipal and industrial customers; intersects with AnoxKaldnes where biological treatment is needed at smaller scale.
Others
- Biothane (Veolia): Veolia sister company specializing in anaerobic and industrial wastewater treatment solutions. A group-level ecosystem peer rather than a direct competitor; positioned as a complementary industrial- wastewater brand within the same Veolia network as AnoxKaldnes.
