Reuse of treated wastewater: case of Bonifacio and Sperone purification stations to irrigate the grounds of the golf de Sperone

In a context of integrated water resource management, REUT is of increasing interest to local communities, particularly coastal communities which must protect natural environments.The case of the city of Bonifacio is a perfect illustration of the mobilization of a municipality for a more sustainable development of their living environment and infrastructures in compliance with regulations.
In 2015, it is planned to reuse treated wastewater from the Bonifacio and Spérone stations to irrigate the golf course of Spérone located on a rocky outcrop in the town. In fact, the irrigation of the golf course competes with the water needs necessary for the development of the city and for agricultural uses, in a region with a high rainfall deficit.

REUSE, a non negligible impact on the environnent

This REUSE project, supported by the department and the Rhône-Méditerranée-Corse Water Agency, has a significant environmental impact which is fully in line with the municipality's desire to save its water resources.
The municipality wants to improve and enhance the quality of the water coming from its wastewater treatment plant while being wasted. A significant asset in terms of the circular economy and sustainable development.

ultraviolets, advanced technology for the treatment of wastewater

For the Bonifacio wastewater treatment plant equipment project, the distance between the WWTP and the golf course required the installation of an ultraviolet water treatment system to eliminate pathogenic microorganisms. This technology guarantees the bacteriological quality necessary for a sprinkler irrigation system (irrigation which throws water into the air through sprinklers or nozzles to make it fall to the surface of the soil in the form of fine drops of water.

Indeed, inhalation during the sprinkling of water that accidentally has degraded bacteriological quality can be a hazard to human health. The REUT for the irrigation of a golf course therefore supposes taking special precautions in the treatment of wastewater. REUT is a very promising approach but less banal than it seems, often subject to environmental and health regulations as well as instruction procedures under the law on water, public health, and classified sites.
The challenge was therefore considerable: to guarantee a quality of treatment in class A category, i.e. the strictest standard, which requires a reduction of 4 log (i.e. disinfection that is 99.99% effective throughout the entire water treatment).

BIO-UV Group solutions suitable for tertiary treatment by disinfecting wastewater

Specialist in UV water treatment for over 20 years, BIO-UV Group realized two joint projects to connect the Bonifacio treatment plant to the golf course of Sperone.

gamme RW adaptée à la désinfection des eaux usées municipales (REUSE)Thanks to its RW range adapted to the disinfection of municipal wastewater, the company has set up a continuous UV treatment with a capacity of 220m3 / h (Step Bonifacio) and 100m3 / h (Step de Sperone) while taking take into account installation and maintenance constraints.
This simple and economical solution without chemicals has helped protect the environment without limiting the reuse of water.

The choice of devices allowing effective and immediate disinfection guarantees the bacteriological reduction of 4 LOG required for this project. This concerns bacteria such as intestinal enterococci (causing septicemia, urinary or abdominal infections among others), f-specific RNA phages, bacterial viruses (Escherichia coli and Salmonella for example) and spores of sulfite-reducing anaerobic bacteria.

BIO-UV Group has therefore succeeded in the mission of equipping the Golf de Sperone with UV systems to allow irrigation of the Golf course while preserving the water resource available to the population.
