A system approach to wastewater biotreatment for the protection of Mediterranean coastal areas
The project is based on the construction of biodepurating systems in six
representative places, each system comprising six constructed cells with
annexed spreading basins for aquifer recharging.
• The six cells - which can be split in two, so totalling
twelve sub-cells - will offer the possibility of exploring a variety of
conditions useful in the process of optimisation, namely detention time,
filling media, depurating plants, water depth, etc.
• Phytodepuration efficiency will be evaluated comparing
physical, chemical and microbiological characters of inflowing and treated
waters.
• The results of system monitoring in the technical,
economic and environmental aspects will be analyzed to issue recommendations
and guidelines and a decision support tool will be released

| Objectives | The principal objectives are : • To monitor, prevent and remediate coastal pollution due to wastewater disposal through the use of multipurpose subsurface-flow constructed wetlands (SFW), inserting them into the productive system of rural societies and, in a more general way, into the surrounding environment. • To gain information useful to help in the optimisation of the design and management of constructed wetlands. • To assess the effectiveness of SFW as a low-tech, low-cost solution to domestic wastewaters treatment. • To demonstrate the possibility of reusing treated waters for irrigation purposes and aquifer recharging. • To conduct an economic-social-environment analysis to evaluate the global impact of wetland construction and management. |
||
| Results | • The main expected outcome is a set of information and
recommendations addressing operators and decision-makers, explaining and
demonstrating how to take advantage of domestic wastewaters instead of
polluting watercourses and seacoasts. • Further outcomes are methods for optimising the design and management of constructed wetlands. • Aspects of interest are also : the biomass production and use as an organic compost or to generate biopower; the observation of effects of treated wastewaters used for irrigation purposes and aquifer recharging; the demonstration action addressing extensionists and operators at large. |
