EMPORE LIFE-EMPORE aims to demonstrate an innovative, cost-efficient and highly

replicable technology for the removal of emerging contaminants from EuropeanWWTPs. Duration: 36 months, from september-2016 to august-2019. Total budget: 1.783.824 € (co-financed by European Commission).

www.life-empore.org

Specific goals To demonstrate that the combination of technologies is able to remove priority

substances and emerging contaminants (ECs), reaching: concentrations below the Directive 2013/39/UE threshold of chlorpyrifos, trifluralin, DEHP and 4-t-octylphenol, concentrations in a 99% of their original concentration of :

ECs included in the 1st watch list of DIRECTIVE 2013/39/UE: diclofenac, 17-a-ethinylestradiol and 17-b-estradiol, Other pharmaceutical pollutants: carbamazepine, ibuprofen, fluoxetine, chloramphenicol and estrone.

To design, construct and set-up a mobile DEMO plant able to reduce the listed ECs. To evaluate the occurrence of ECs in Europe. To assess the environmental and socio-economic impact of the project. To study the transferability of the project results to other European places with a

similar situation regarding ECs.

Pilot plant locationBenidorm

(Alicante, Spain)

Benidorm is a popular tourist destination in Spain, whose population fluctuates considerably especially during Christmas, Easter and summer seasons. High presence of elderly population. Discharge of pharmaceutical products in wastewater.

Benidorm Wastewater Treatment Plant (BWWTP) (source: EPSAR)

B1: Characterization of water samples GOAL: To quantify the pre-selected pollutants present at the inlet/output of BWWTP. To study the seasonal variability of the concentration of ECs in the wastewater

received by BWWTP.

METHODOLOGY Annual analytical campaign of the influent and effluent of BWWTP (54

samples from the influent and effluent) from Nov. 2016 to Dec. 2017. Analytical techniques: GC-MS/MS and HPCL-MS/MS
