Veolia Water Technologies specializes in water treatment solutions and provides the complete range of services required to design, build, maintain and upgrade water and wastewater treatment facilities for industrial clients and public authorities. We help cities and industries to manage, optimize and recycle water.

Our portfolio of technologies features everything from state-of-the-art water and wastewater treatment technologies to evaporation and crystallization, energy- producing sludge treatment, desalination plants, and mobile water services. These innovative technologies maximize energy production and product recovery, allowing our clients to extract raw materials and capitalize on valuable byproducts. What is discarded by some becomes a resource for others.

We develop access to these resources through standardized technologies, state-of-the- art customized solutions and water reuse techniques. By optimizing both treatment processes and technologies, we help our clients reduce their water footprint while generating considerable savings in energy and chemical consumption.

Veolia is furthermore the only company in the world that can combine all that expertise, process knowledge and our existing digital solutions into one comprehensive digital service package, Aquavista™, which supports and enhances the operation of industrial as well as municipal installations.

STRUVIA™ Sustainable recycling of phosphorus from wastewater

Phosphorus is a key ingredient in the fertilizers used in agriculture and for animal feed. STRUVIA™ allows for phosphorous to be recovered as struvite crystals from the effluents produced by industrial, agricultural and municipal activities. This opens the way to a local reuse of phosphorus, especially in agriculture.

APPLICATIONS BENEFITS Recovery, valorisation and reuse • Low investment and operating REFERENCES of phosphorus contained in costs Brussels North (Belgium) wastewater and in concentrated • Limited footprint and building � Prototype reactor industrial water as struvite. height requirements (0.2 to 0.5 m3/h) • Recycle struvite by incorporating it Helsingør (Denmark) PERFORMANCES into a fertilizer � First industrial unit • Reduction of internal phosphorus • The recovered phosphorus is made (4.8 tons of phosphorus load freely available for plants and crop extracted per year) • Reduction of chemical sludge • Cadmium free and improvement production of carbon footprint • Prevents operation downtime and maintenance cost caused by uncontrolled struvite precipitation • Reduced needs for chemicals for P-precipitation RESOURCING THE WORLD 41

ECRUSOR™ Solution for depackaging and preparing biodegradable wastes for energy generation Ecrusor™ is a patented process to separate biodegradable wastes from commercial packaging. The single unit then grinds the organic material into a homogeneous slurry. Once processed by Ecrusor™, the highly organic, biodegradable material can be combined with indigenous and imported sludge and sent to the digester/biogas system.
