AERIS is a spin-off of the Autonomous University of Barcelona comprising experts from the GENOCOV research group (UAB) aimed at helping industries and public entities to improve the environmental quality of their emissions. AERIS has a large experience designing and building highly automated pilot plants for research purposes. These are always developed according to the specific customer needs. This includes fermenters, air-lift reactors, sequencing batch reactors (SBR), photobioreactors, etc. Also, other of AERIS main business areas is the optimization of the biological and/or physico-chemical depuration of natural and industrial liquid streams containing nutrients, COD and/or recalcitrant compounds. In this field, numerous R+D and technological implementation projects have been carried out in the last years, mostly in paper-producing, tannery and food industries.
In the frame of HYDROUSA, AERIS will oversee the design and construction of an advanced UASB anaerobic digester which will be implemented in the WWTP of Antissa (Lesbos). This system will remove most of the organic pollution of the wastewater while producing biogas, a nutrient-rich liquid effluent and only small amounts of sludge that can be further subjected to composting.
