Based on decades of engineering experience in the water industry, all around the world, as well as its Research & Development activities, Saur has developed cutting-edge technologies for communities and industry. These cover the entire water cycle (from production of drinking water to wastewater treatment) and are designed to optimise facilities’ operation.
Among the Group’s entire technological portfolio, some examples of high value-added solutions include:
Carboplus®: a Saur process for eliminating micropollutants after water leaves treatment plants, to reduce their presence in the natural environment or eliminate them after water leaves drinking water treatment plants to eradicate any long-term health risk. Its applications are municipal and industrial.
Calcycle®: another Saur process, this reduces the calcium hardness of water. It has the double advantage of being environmentally friendly – particularly since it does not result in any discharges into the sewerage network – and compact – as it takes up very little space on the ground.
Industrial waters: Saur offers a full range of industrial technologies and processes, which aim to optimise and secure its customers’ industrial operations (“pure water” and process water, filtration, management of industrial wastewater, etc.)
Since the 1950s, phosphorus has been a key ingredient of all the fertilisers used to improve agricultural yields. But the phosphate it is derived from is not a limitless resource, and its availability could easily trigger increasingly serious geopolitical tensions in future years.
At Criteuil-la-Magdeleine in the Charente region of France, the Bernac drinking water production plant has been using a Calcyle catalytic decarbonation unit for the past four years to significantly reduce water hardness.
Reducing – preferably eliminating – waterborne micropollutants is an essential challenge in protecting aquatic environmental quality and human health. Set by ONEMA (The French National Agency for Water and Aquatic Environments), this goal is consistent with the EU Water Framework Directive (WFD), which aims to “achieve good status for all waters”.
Acting ahead of new European standards on micropollutants, SIAAP (the company that provides wastewater management services to the residents of Paris and its surrounding region) introduced a process to analyse effluent from its wastewater treatment plants in order to decide how it should be treated to meet future regulatory standards. The outcome was the on-site installation of a 50m3/ hour CarboPlus® pilot plant by Stereau.
