Global Research Centers

DENARD (Degremont Technologies North American R&D Center)

Established in 1997, DENARD is a founding member of the Virginia Biotechnology Research Park located in Richmond, VA. DENARD conducts a broad-based RDI program scope covering process applications such as biological filtration, biosolids treatment, clarification, membrane filtration and UV disinfection for both drinking water and wastewater treatment.


AQUASOURCE, Toulouse, France

Specializing in Ultrafiltration, Aquasource develops technologies and products designed to optimize water treatment performance. RDI activities are focused on the development of new membranes, modules and process skids / trains dedicated to drinking water, wastewater and re-use applications. Aquasource innovations guarantee reliable and efficient solutions to meet client needs.

Degremont Technologies Ltd., Zurich, Switzerland

Specializing in ozone generation technology RDI program is renowned for “raising the bar” with developments such as the “Self-centered AT dielectric segment technology” that have allowed for production of increased ozone concentrations with greater energy efficiency.

Ozonia’s commitment to continuous improvement has contributed to a worldwide ozone production capacity exceeding 15,000 kg/h since 1991. With Innoplana, Thermal Drying is one of our selected solutions for sludge treatment. RDI focuses on safety, low energy and dust free parameters.

Research Tools

Advanced Analytical Services

Project Chemists at DENARD work in a lab equipped with a range of advanced instrumentation to fully characterize both water and wastewater samples in order to produce the essential data required to meet a client’s water treatment needs. Consultative “Treatability Studies” are conducted to develop process operating parameters and to predict full-scale performance.

Computational Fluid Dyamic Modeling

DENARD’s team of Designers & Research Engineers utilize the latest CFD-modeling software to optimize equipment design and model plant hydraulics. The tool is useful in simulating a range of complex phenomenon including UV Reactor Design, Cannon® Mixer bubble generation, Integrated Fixed Film Activated sludge systems.

Collimated Beam Testing

The emergence of UV irradiation as a viable strategy for disinfection of water and wastewater has created a need for evaluation of UV dose requirements to achieve specified effluent quality criteria.

DENARD has developed a comprehensive collimated-beam test protocol for generation of laboratory dose-response data, which is then used to derive a design UV dose for full-scale systems. Combining the use of a standardized protocol with advanced sample characterization such as particle size distribution analysis, DENARD aims to increase client confidence in UV system performance by ensuring the reproducibility of test results and allowing meaningful comparison of data.

Pilot Testing

With a fleet of over 30 field-scale pilot units in equipment ranging from UV reactors to clarification systems and handling flows up to 350 gpm Degrémont Technologies conducts pratical, on-site studies for determination of process performance prior to full-scale investment. This approach has proven successful on thousands of the most difficult municipal and industrial applications worldwide.

Bench Scale UF Fiber Production

Aquasource’s RDI Department is equipped with a dedicated spinning unit. Independent of the commercial production equipment, researchers are free to evaluate formulation improvements and explore new UF fiber development dedicated to diverse applications.

Ozonia Triplex Ozone Vessel

By integrating operational data from a fully automated ozone generator test stand with mathematical modeling results, Ozonia Researchers are able to determine an ozone generator’s performance efficiency under a wide range of operating conditions such as feed gas pressure, cooling water temperature, etc. The Triplex vessel ozone test stand incorporates state of the art ozone monitoring instrumentation including a UV spectrophotometer for measuring ozone concentration and an IR-spectrophotometer for gas composition analysis.

Degremont’s 2PAD® Two-Phase Anaerobic Digestion technology is US EPA certified for the production of Class A biosolids, facilitating land application without restriction. By separating the acid and methane producing stages the digestion process efficiency is greatly enhanced yielding maximum pathogen destruction, increased biogas production and significant reductions in total hydraulic retention time. Ultimately this translates into increased energy efficiency, smaller digester volumes and / or increased sludge loading rates. Use of the high-rate Cannon® Mixer system ensures peak digester performance and reduced operating costs.

Increasing environmental awareness and the growing market for wastewater reuse has accelerated the implementation of UV Disinfection. The Aquaray® 3X technology combines the use of LP Amalgam lamps (160W UVC) and a patented vertical lamp reactor design to deliver maximum disinfection capacity with significantly fewer lamps and a compact plant footprint. A novel flow pacing controls feature supports variable lamp output and row-by-row operation to allow optimized disinfection while maximizing energy savings. As a “green” alternative to the use of chlorine, the Aquaray® 3X has already generated real financial gains for users. In 2006, it was awarded the Frost & Sullivan award for Technology Innovation of the Year in the US Water and Wastewater treatment category.

DEGRÉMONT’s patented AquaDAF® dissolved air flotation system has revolutionized conventional clarification practices. Operating at rise rates upwards of 30 m/h, the AquaDAF® plant footprint is two to three times more compact than conventional flotation units. Originally specified for drinking water clarification applications, the AquaDAF is now proven for a diverse range of treatment applications including tertiary Phosphorous removal and spent filter backwash.

The Biolysis O technology was developed to reduce the quantity of biological sludge production from activated sludge systems, addressing a critical financial and environmental concern of today’s wastewater treatment plants. Incorporating the use of a specially designed mixing reactor and a variable Ozone dosing strategy allows operators to fine-tune performance requirements yielding sludge reduction that ranges from 30 to 80%.

The growing environmental movement to introduce “Clean Air” legislation aimed at reducing sulfur dioxide and nitrogen oxide emissions from coal-fired power plants, has accelerated Degremont’s development of a biological treatment process targeting the removal of pollutants captured in the wastewater stream purged from the air pollution control equipment. Key to this patent-pending process is the staged reactor design and automated controls which select for the growth of distinct microbes within the naturally occurring population for sequential removal of nitrogenous compounds and heavy metal contaminants such as Selenium and Chromium, which have proven difficult to remove with convential physical chemical treatment. Fundamental biological reactor technology supports robust process and operational flexibility.

First launched in 1984, Aquasource’s R&D Program delivered the LIFEA® cellulose acetate membrane technology which resulted in the world’s first Ultrafiltration plant for drinking water treatment at Amoncourt, France in 1988. Recent development of the INEA® cellulose acetate membrane provides improved permeability and a 12% increase in the filtration surface within each module, significantly reducing capital investment costs. The ALTEON® hydrophilic polysulfone membrane with its ability to withstand more aggressive cleaning regimes makes it ideally suited for direct surface water filtration, wastewater reuse and seawater desalination pretreatment applications.

Ozonia has developed a new dielectric technology that will revolutionize Ozone generation technology.
