INTEGRATED TREATMENT SYSTEM WITH CONSTRUCTED WETLANDS
IN CATALYTIC + FOTOOZONIZATION OF WASTEWATER IN UNIVERSITY CAMPUS
Tamara research deals on the study of integrated system with constructed wetlands and a Catalytic Photoozonization (UV/TiO2/O3) for the treatment of university campus sewage. The integration WC’s + FTC involved constructed wetlands experimental tanks with 90 L useful volume supported with a system composed of gravel stones and medium/thick sand.
The experimental wetland line were designed with the following tanks: 1)vegetated system, 2)vegetated system with greenhouse 3)intermediary system vegetated with submerged macrophyte in superficial flow 4)substratum system.
Plants used were Hymenachne grumosa for stage 1 and 2, and Myriophyllum aquaticum for stage 3. Stage 4 was leave without plants.
The rate of ozone photoproduction was 160 mg h-1 and applied within four hours of treatment
The general and specific standards for water quality characterization of the final effluent on the integrated system revealed that the batch configuration reduced COD and BOD5 on average of 62 and 88%, respectively. The reductions of TKN, NH3-N and Total Phosphorous on average of 27.4, 27.1 and 63.3%, respectively.

PROJECT N. 2
"Woodrbanization. A travel from IBA Emscher Park to Treviso 2050"
by Silvia Rasia and Francesca Volpiana - VENICE UNIVERSITY - IUAV
"Our aim is to experiment with the lessons learned from the IBA Emscher Park model to rethink our territory. Utilizing such a model to redesign not only the river but the processes along the river as well, and understand which real spaces it occupies, those that, although noncontiguous, still belong to it.
We want to reflect on the Parco Del Sile and the pits around it with a logic of continuous passing from the large to small scale and vice versa. This strategy allows us to maintain an image which perceives the whole and at the same time controls local interventions; a series of case studies in which criticality and potentiality are key frames to understand project opportunities, transforming them into models capable of triggering new processes where interdisciplinarity will be the key word taught us by the Germans and the IBA.
In this logic we utilize fitodepuration to change the future image of our territory: the pits, industrial and polluted places, can be transformed in sostenible areas immerged in new woods and the new buildings can utilized the fitodepuration as depuration system". By Silvia and Francesca
PROJECT N. 3
Matteo Tamburini degree in Natural Sciences at Padova University - 2010
The present study has as object a real scale pilot system in the municipality of Vigonza, managed by ETRA s.p.a.
The plant has operated continuously for the first year from its implementation (1999), for the purposes of initial testing.
Then he was stopped in 2001. Since September 2009, to make further studies and in implementation of a mobile pumping, the tanks were replenished and restored the system
constructed wetlands with new macrophyte planting (iris pseudacorus and canna indica).
The objective of this thesis was to evaluate the features and ecological status of the beds after a long stop and the comparison, after the restart, with the efficiency of treatment.
