Sanitary Engineering Laboratory of National Technical University of Athens hosted students of the Department of Environment of Aegean University at HYDRO 1 and HYDRO 2 demonstration sites in Antissa Village. The students along with Athanasios Stasinakis got the chance to explore the water treatment solutions and agriculture innovation developed in our demonstration sites.
HYDRO1 consists of a wastewater treatment train with a maximum capacity of 100 m3/d (anaerobic treatment stage followed by vertical flow constructed wetlands and post treatment units), a biogas upgrade system, a composting unit and four novel pilot scale constructed wetland systems.
The anaerobic treatment takes place in two UASB reactors, leading to the production of biogas and a small amount of sludge. The process recovers energy in the form of biogas, has low operating expenses and low footprint requirements. The biogas produced is collected in a gasometer and is being upgraded in order to produce pure biomethane which will be used as fuel, while the sludge is treated in a sequence of a sludge drying reed bed and a composting unit.
Meanwhile, HYDRO 2 combines the regenerative capacities of agroforestry with the use of reclaimed water and nutrients. The irrigation of the agroforestry system is divided into two different irrigation systems; one through drip irrigation and the other one through traditional stone channels coupled with furrow irrigation. Up to 100 m3 of reclaimed water per day (in summertime) is available for irrigation.
The students were guided to the operation of the demonstration sties, learn about the objectives and aims of HYDROUSA Project and ask questions to the experts that were present.
