New process for Optimizing Wastewater reuse from Mauguio to the Mediterranean Area
4 June, 2050
Waste water source
The water comes from the Mauguio domestic wastewater treatment plant (activated sludge of 24 000 EH – around 3 000 m³/day). No industrial wastewater are connected.
Reclaimed water was send to the test fields by use of a very small distribution network of less than 50 meters length.
The irrigated plot is subdivided in three blocks each supplied with a different water quality. Two water qualities come from the treatment unit, while the other represents a reference water quality for the region. Irrigation application methods are tested on each block with drip (below and above ground) and sprinkler irrigation.
Waste water treatment description
Nutrient removal : Activated sludge
Pesticide removal : none
Disinfection : UV and ultrasound techniques provide disinfection
Suspended solids removal : Several filtration have been tested: Sand filtration, Microfiltration and ultrafiltration
The average daily discharge is 2,530 m³.
Extent of the agricultural beneficiaries
In total the irrigated arrea is nearly 500m² big.
The cost of the project is 2,887,000 euros over 3 years.
Type of agreement
Seen the explorational status of the initiative, a consortium agreement was provided between the project partners.
The project provided major results about:
- water reclamation technologies performances
- drippers clogging
- Aspersion irrigation of aerosol
These results can be found through this link.
Jauzein, V, Perot, J, Clerc, J et al. A R & D platform dedicated to the development of the wastewater REUSE in France and in the Mediterranean basin : NOWMMA
Tests of different high-process disinfection technologies. Experiments on biofilm growth and bacterial growth in drip irrigation using reclaimed water. The main objective of the pilot is to test disinfection technologies.
Modelling the spraying phenomenon to assess the risks of contamination in order to formulate recommendations on of French regulation regarding wind effects on sprinkler irrigation.
