Biological Treatment

Veolia offers biological solutions to help systems comply with nitrogen and phosphorus limits that are compact, robust, resource efficient, and easy-to-operate.

MBBR and IFAS Offerings

Field's Point WWTF

AnoxKaldnes™ is the global leader in MBBR and IFAS technologies. We provide the most advanced MBBR and IFAS technologies supported by more expertise and with more installations (600+) than any other MBBR and IFAS system provider.

Deammonification Process

K5 Media

ANITA™ Mox is a robust, single-stage nitrogen removal process with low carbon footprint based on the MBBR or IFAS platform. The ANITA™ Mox process is specially developed for treatment of streams highly loaded in ammonia, such as effluents from anaerobic treatment, drying condensates, industrial wastewaters, and landfill leachates.

Biologically Active Filter (BAF) Technologies

Syracuse, NY Tertiary Nitrification System

BIOSTYR® process combines biological treatment, and solids separation via filtration into one compact system. BIOSTYR® DUO (BAF + MBBR) adds a second media layer for increased carbon, solids and nitrogen loading capabilities. With over 160 installations throughout the world, BIOSTYR® is proven to be an exceptional technology for BOD removal, nitrification, denitrification and solids removal, with improved energy efficiency and 20% of the footprint of conventional activated sludge technologies.

Immersed Membrane Bioreactor System

West End Development, Bermuda MBR System

NEOSEP® is a Membrane Bioreactor (MBR) system that offers the smallest footprint and lowest energy use on the market today with the incorporation of the FibrePlate™ membrane. FibrePlate™ is a hybrid of hollow fiber and flat plate technologies that retains the strengths while eliminating the weaknesses of conventional MBR membrane technologies. Our experience in over 230 MBR systems provided and/or operated by Veolia worldwide, coupled with the most innovative, compact and efficient membrane technology available, brings our clients tremendous value. 

Activated Sludge Technologies

Oxidation Ditch

We offer a wide range of solutions for activated sludge treatment providing our clients guaranteed total process performance with a single point of responsibility. The core offerings in our Activated Sludge Systems are based on Phased Isolation Ditch technology, or Phased Isolation Technology. Phased Isolation Technology is a type of continuous flow activated sludge process wherein one or more reactors alternate between oxic and anoxic phases. Phase alternation is based on a timed sequence of online nutrient monitoring. These systems offer very efficient nutrient removal without multiple reactor zones or multiple mass recycle loops. 

High Purity Oxygen System

OASES® is an oxygen-activated sludge process for secondary treatment of wastewater. It is an automated, safe, and efficient oxygen-activated sludge treatment system for upgrading or retrofitting treatment facilities existing pure oxygen systems.
