At Veolia, we combine global expertise and local experience to deliver a portfolio of proven wastewater treatment technologies for industrial, municipal, and pharmaceutical applications. Each technology is designed to meet the highest standards of efficiency, compliance and sustainability, helping organisations optimise performance, reduce operating costs, and support water reuse initiatives.

Explore each solution below to learn how our systems can address your specific wastewater challenges, with links to full technical details and case studies.

High-quality effluent in a compact, flexible system

The ZeeWeed™ MBR combines biological treatment with immersed ultrafiltration membranes to produce consistently clear, reusable wastewater. Its compact design eliminates secondary clarifiers and supports both new-build and retrofit projects.

High-performance anaerobic treatment processes

The Biobed® Advanced system combines the excellent performance of the Upflow Anaerobic Sludge Blanke (UASB) - renowned for its high COD removal efficiency - with the cost effectiveness and small footprint of the Expanded Granular Sludge Bed (EGSB), achieving multi-level gas separation.

Biological treatment of heavily contaminated wastewater

Memthane® is an anaerobic membrane bioreactor (AnMBR) that maximises renewable energy production while producing excellent-quality effluent that can be reused or discharged directly to sewer. AnMBR technology is ideal for the treatment of wastewater streams and slurry with high concentrations of organic matter, solids, fat, oil and grease.

Key Benefits:

• Cost effective & efficient | Transforms waste treatment from a cost centre into a revenue opportunity by converting organic waste into renewable energy.

• Reduces environmental footprint | Energy-positive operation means the system generates more energy than it consumes, making it one of the most sustainable wastewater treatment options available.

• Robust, reliable treatment | This odour free operation is easily scalable to meet individual plant characteristics. Membrane filtration ensures consistent, high-quality effluent regardless of influent variations, meeting stringent discharge standards

The Moving Bed Biofilm Reactor (MBBR)

The Moving Bed Biofilm Reactor (MBBR) solution by AnoxKaldnes^Ⓡ is a biological process where biofilm grows on carriers suspended in wastewater. This technology implements the biofilm fixed on the surface of a carrier. This biological wastewater treatment and biological water treatment process treats pollutants in a cost-efficient way and it is used across almost all municipal and industrial market sectors such as food and beverage, mining, oil and gas, and pulp and paper.

Moving biofilm reactor, in a standardised package. 

MBBR Pack technology is based on the biofilm principle, which uses microorganisms for biological treatment of wastewater. To meet the different challenges and quality objectives of each industrial and municipal customer and to provide them with global solutions, the MBBR Pack can be combined with numerous processes designed and manufactured by Veolia for both the pre-treatment and secondary treatment stages.

The AnoxKaldnes™ Z-MBBR is a hybrid wastewater treatment system that combines MBBR biofilm carrier technology with conventional activated sludge in the same reactor. This integrated approach uses both suspended biomass and biofilm growing on moving carriers to deliver improved nutrient removal, and superior process stability.

Key benefits:

• Enhanced treatment capacity: Transforms existing activated sludge systems into high-performance hybrid reactors by adding biofilm carriers that provide additional surface area for microbial growth.
• Eliminates variations in performance due to changes in biofilm thickness: Removes limitations associated with clogging of the carriers
• Small footprint: Compact modular design requires minimal land area, making it ideal for space-constrained sites or expensive urban locations.
• Z-MBBR delivers all the conventional advantages of MBBR; small footprint, stability, low maintenance and robust treatment while offering the ability to customize unique solutions

The MBBR Solution for High Ammonia Waste.

The ANITA^TM Mox processes - MBBR and Hybas (Integrated Fixed Film Activated Sludge) are single-stage deammonification technologies where greater than 90% of ammonia and 75-85% of total nitrogen can be removed. The ANITA™ Mox process is performed in 2 steps: aerobic nitritation and anoxic ammonia oxidation performed by anammox bacteria. 

eXeno™ is a moving bed biofilm reactor (MBBR) technology that uses specialised microorganisms growing as a biofilm to biologically degrade and treat micropollutants with little or no chemical dosing, low energy consumption and operational costs.

Highly effective technology for removing dissolved and dispersed hydrocarbons.

MPPE® is a fully automated, remote controlled and guaranteed method for removing dissolved and dispersed hydrocarbons from water in one step, with efficiencies of 99.99% down to below ppb level, or as specified. This process applies to different types of hydrocarbons, including aliphatic, aromatic, polyaromatic, halogenated, such as chlorinated and bromated.

Ensures 99,99% of dissolved solvents removal from waste streams.

MPPS removes and recovers solvents by means of adsorption on dedicated media. By applying steam regeneration of the loaded media, the solvents are recovered in a concentrated form. This makes them suitable for either reuse, or if that is not possible, the concentrate can be disposed of as high caloric waste.
