As part of the technical actions of the project, the team of researchers from CARTIF visited this week the facilities of the Spanish demonstrator, the HUERCASA vegetable processing factory, to collect samples of wastewater.

This action is one of the first to be developed to demonstrate the technical and economic feasibility of the innovative concept for the treatment of wastewater from the fruit and vegetable processing industry based on the cultivation of heterotrophic microalgae to replace, in the long term, the traditional aerobic digestion as the preferred method for treating these streams since, instead of sludge residues and nutrient losses, added value microalgae are produced, which is the main objective of the project.

The samples collected in HUERCASA, come from the processing of vegetables from three different streams of residual water to know their physical-chemical composition and the viability of their treatment with microalgae.
