Scientific objective
The objective is to provide the scientific basic for developing costeffective filter technologies targeting P-retention and N-removal in agricultural drainage discharge.
SupremeTech will thus develop filters to be implemented at strategic landscape positions targeting a major P transport pathway. The sustainability of the approach relies on using industrial (by-/recycled) products as filter substrates and recycling the P-saturated filters to agricultural land.
The project aims specifically to:
- explore the potential of industrial products as high-affinity P filter substrates, and to investigate new P retention mechanisms,
- explore new innovative filter technologies targeting drainage losses,
- apply new principles for increasing the filter denitrification capacity,
- analyse the recycling of P-saturated filter materials as soil amendments,
- assess the contamination risk and quantify the filter function for other agricultural pollutants,
- model filter systems to provide design parameters and optimize filter performance, and
- analyse the cost-effectiveness of implementing filter technologies in landscapes.
