Strategy and work plan description

 

The strategy of the SWINGS methodology consists in studying five types of configurations based on anaerobic and natural systems. Firstly, one stage anaerobic and CW systems; two stage anaerobic and CW systems and low cost disinfection systems will be carried out separately. Subsequently, the best configurations of these three types, according to organic, nutrient and pathogen removal efficiency; biogas and excess sludge production, will be integrated in whole configurations.

The project starts with WP1 “Specification of field applications”, within all partners of the project will discuss and deliberate different opinions about the mentioned treatment alternatives. So that, the definition of different configurations will be discussed by all partners and will be according to each region specific demands.

Finished WP1, WP2 “Design and construction of the combined system” is starting. All the work associated with the design parameters (input, output and operation data); system construction or adaptation (according to available facilities of each partner) and installation will be performed in this WP.

WP3 “Start-up and steady-state operation of systems” is oriented towards the operation of combined anaerobic and CW configurations as a low-cost and complementary methodology to treat WW. Firstly, different combined pilot plants will be adjusted and started-up for evaluation of problems in operation and integration of the technologies. The following task will consist in achieving steady-state operation.

In WP4 “Optimization of AD and CW configurations”, the operation of AD and CW pilot plants at feasible organic and hydraulic load limit will be carried out in the two first tasks. In the third task of this WP, depth level of horizontal CW gravel bed and oxygen concentration of vertical CW will be evaluated in order to improve CW operation. Finally, monitoring of GHG released from CW and metal concentration will be conducted along different periods of CW operation.

In WP5 “Disinfection systems and sustainable pathogen monitoring technique”, innovative, eco-efficient and economically feasible technologies for nutrient recovery and provide safe water will be tested and optimized. This includes the evaluation of low cost disinfection methodologies based on filtration, lagooning and solar methods at pilot scale. At the same time, techniques for cost-effective pathogen monitoring will be integrated and validated.

Based on results of WP3-5, sustainable and integrated approaches of AD, CW and post-treatment methodologies for water reuse and recycling will be studied in WP6 “Selection methodology and integral configuration”. A decision support method will be conducted in order to select the sustainable and efficient treatment technologies studied and optimised in the project.

Dissemination and exploitation actions are planned in WP7, while all management and coordination activities of the project are included in WP8.
