In this study, a 1200L outdoor pilot scale microalgal photobioreactor (PBR) was used for toilet wastewater (WW) treatment and evaluate its ability to remove pharmaceutically active compounds (PhACs). The PBR was operated at two different hydraulic retention times (HRTs), which were 8 and 12days, during Period I (September-October) and Period II (October-December), respectively. Algal biomass concentrations varied by operating period because of seasonal changes. Nutrients (ammonia, nitrogen and total phosphorous) and chemical oxygen demand (COD) were monitored and efficiently removed in both periods (>80%), attaining the legislation limits. At the theoretical hydraulic steady state in both periods, pharmaceutical removal reached high levels (>48%). Two harvesting techniques were applied to the PBR microalgae effluent. Gravity sedimentation was efficient for biomass removal (>99% in 7min) in Period I when large particles, flocs and aggregates were present. In contrast, a longer sedimentation time was required when biomass was mainly composed of single cells (88% clarification in a 24h in Period II). The second harvesting technique investigated was the co-pelletization of algal biomass with the ligninolytic fungus Trametes versicolor, attaining >98% clarification for Period II biomass once pellets were formed. The novel technology of co-pelletization enabled the complete harvesting of single algae cells from the liquid medium in a sustainable way, which benefits the subsequent use of both biomass and the clarified effluent.

Hospital wastewaters are a main source of pharmaceutical active compounds, which are usually highly recalcitrant and can accumulate in surface and groundwater bodies. Fungal treatments can remove these contaminants prior to discharge, but real wastewater poses a problem to fungal survival due to bacterial competition. This study successfully treated real non-spiked, non-sterile wastewater in a continuous fungal fluidized bed bioreactor coupled to a coagulation-flocculation pretreatment for 56 days. A control bioreactor without the fungus was also operated and the results were compared. A denaturing gradient gel electrophoresis (DGGE) and sequencing approach was used to study the microbial community arisen in both reactors and as a result some bacterial degraders are proposed. The fungal operation successfully removed analgesics and anti-inflammatories, and even the most recalcitrant pharmaceutical families such as antibiotics and psychiatric drugs. ; This work has been funded by the Spanish Ministry of Economy and Competitiveness (project CTM2013-48545-C2) and partly supported by the European Union through the European Regional Development Fund (ERDF) and the Generalitat de Catalunya (Consolidated Research Groups 2014-SGR-599, 2014-SGR-476 and 2014-SGR-291).

The mission of the Catalan Institute for Water Research (ICRA) is to implement a holistic, multidisciplinary approach to water research, taking into account all components related to freshwaters and human-used waters. The ICRA has developed a coordinated, cooperative organization structure to allow this multidisciplinary approach across a broad spectrum of water related sciences and technologies. ICRA's main goals are to provide scientific and technological perspectives and tools to issues derived from water needs, scarcity, and ecosystem conservation in the Mediterranean context ; This work has been supported by the Spanish Ministry of Economy and Competiveness through the project SCARCE of Consolider-Ingenio 2010 program (CSD2009-00065) and the projects CARBONET (CGL2011-30474-C02-01), GEISTTAR (CTM 2011-27163), WATERFATE (CTM2012-38314-C02-01), (DEGRAPHARMAC-CTQ2010-21776-CO2-02), CDTI INNPRONTA ITACA project (IPT-2011102), MBRControl (CDTI - OHL MedioAmbiente INIMA SAU) andARCOS (CGL2012-33033).
