In-Farm remediation by solar photocatalysis of agro-waste water with pesticides from remnants, cleaning and rinse

Project description

The project will demonstrate a technically, economically and ecologically feasible method by which pesticide residues contained in the waste water produced by farms can be neutralised. The use of innovative equipment will allow pesticide remnants in containers and treatment tanks and rinse water from tanks after cleaning of machines and equipment to be dealt with.

The project will develop a pilot waste-water decontamination facility to be tested on five farms. It will use a solar photocatalysis degradation process. The system uses solar energy (UV irradiation), sodium peroxodisulphate (Na2S2O8) and a catalyst (TiO2 and ZnO). The catalyst is recovered at the end of the process for its re-use. Treated waste water is no longer contaminated and can be used again for any purpose (e.g. irrigation).

Expected results

The main result of the project will be the development of an on-site waste-water decontamination plant able to completely degrade pesticides without generating any other residue.
The main expected long-term achievement of the project is the implementation of the Aquemfree system in medium- size and large farms, which would provide a solution for 80-90% of this environmental problem, at least in Mediterranean farms thanks to their solar irradiation conditions.

Success factors

Multi-actor approach: manufacturers and potential final users are involved in the project. Research institutions: IMIDA and University of Murcia
Potential final users: FECOAM (Murcia Federation of Agricultural Cooperatives)
System manufacturer: Novedades Agrícolas S.L.

Performance indicators

The project includes the evaluation of the prototypes from the technical, environmental and economic points of view.

Repeatability & Applicability

The final objective is to have a commercial system ready in the farms.
