Project goals

The main goal of this proposal is the development of a technology for phosphate removal from wastewater using a byproduct from the magnesia production industry and the implementation of this technology into a WWTP in order to improve water quality.

This methodology will be developed by the consortium with the aim of reducing phosphate concentration by chemical precipitation using by-products from MAGNA (making them profitable). LUREDERRA will coordinate research activities, and SMSA will be in charge of implementing the new demonstration plant on its facilities.

Eutrophication is the process by which a body of water acquires a high concentration of nutrients (phosphates and nitrates) that promotes excessive growth of algae which leads to produce organic matter that deplete the water of available oxygen, causing the death of organisms such as fish.

Eutrophication is mainly produced by phosphates spilled into the river by WWTP. The technology proposed in this project will reduce phosphate concentration from waste water decreasing phosphates in river.

This proposal would be a solution for many WWTP which need to improve phosphate removal from waste water. In order to get this final aims different objectives have been planned:

Scientific objectives:

- Development of a technology more efficient and economical to remove phosphates from waste water

- Demonstration of the viability of using this technology in a WWTP

- Demonstration of phosphate removal efficiency in water using the treatment proposed

- Valorization of a by-product of MAGNA as a precipitant agent to remove phosphates from waste water

- Study of the best way to manage the precipitate formed in the reaction Environmental objectives:

- Increase of water quality decreasing pollutants concentration

- Improvement of environmental protection according to “Water European Directive”

- Decrease of the eutrophication in river due to the decrease of phosphates concentration

- Reducing the carbon footprint of the human activity
