  5. GENERAL AIM AND INNOVATIVE ASPECTS • The aim of WATINTECH is to develop effective decentralized treatment concepts for sewage and urban run-off to recover: • Water • Energy (methane) • Value-added products (caustic, oxygen)

  6. GENERAL AIM AND INNOVATIVE ASPECTS • The aim of WATINTECH is to develop effective decentralized treatment concepts for sewage and urban run-off to recover: • Water • Energy (methane) • Value-added products (caustic, oxygen) • Dynamic interaction among the different technologies, flexibly adjusting their operations to the requirements.

  8. MAIN FINDINGS & NEXT TARGETS 1a WATER production: wastewater FO filtration AIM: technical and economic evaluation of long term filtration

  9. MAIN FINDINGS & NEXT TARGETS 1a WATER production: wastewater FO filtration AIM: technical and economic evaluation of long term filtration • MAIN FINDINGS: • WW treatment by FO requires pretreatment to reduce membrane fouling • Membrane permeability is recovered by physical and chemical cleaning • Mainly reversible fouling: high recovery after chemical cleaning • NEXT TARGETS: • Spiral wound membranes evaluation in demo pilot plant. • Evaluation of alternative feed pretreatment technologies (sedimentation, filtration, DAF, coagulation-flocculation-sedimentation, • Optimization of the filtration/cleaning cycle.

  10. MAIN FINDINGS & NEXT TARGETS 1b WATER production: rain water harvesting with Constructed Wetlands AIM: to assess the effect of operational parameters on CW performance for rain water run-off in Mediterranean climates and to evaluate the impact of “accepting” nutrient rich effluents from domestic treatment technologies HF

  11. MAIN FINDINGS & NEXT TARGETS Typha latifolia Canna indica 1b WATER production: rain water harvesting with Constructed Wetlands Tank P P P FWS Pond AIM: to assess the effect of operational parameters on CW performance for rain water run-off in Mediterranean climates and to evaluate the impact of “accepting” nutrient rich effluents from domestic treatment technologies P Disposal Reuse P HF

  12. MAIN FINDINGS & NEXT TARGETS 1b WATER production: rain water harvesting with Constructed Wetlands AIM: to assess the effect of operational parameters on CW performance for rain water run-off in Mediterranean climates and to evaluate the impact of “accepting” nutrient rich effluents from domestic wastewater treatment FWS HF HF

  13. MAIN FINDINGS & NEXT TARGETS 1b WATER production: rain water harvesting with Constructed Wetlands (CW) • MAIN FINDINGS: • The use of hybrid CW for treatment of storm water run-off (IKEA parking area) and domestic wastewater (SBR) in Mediterranean climate conditions id feasible • Main removal of heavy metals was observed in HF configuration • Microbial indicators and pathogens removal was mainly observed in FWS • NEXT TARGETS: • Wastewater quality and hydraulic conditions monitoring • Bio-agronomical analyses and evaluation of water losses in CW

  14. MAIN FINDINGS & NEXT TARGETS 2 ENERGY production from concentrated wastewater AIM: Optimize energy recovery of an AnMBR treating wastewater concentrated with FO. Effect of dynamic change of temperature and HRT

  15. MAIN FINDINGS & NEXT TARGETS 2 ENERGY production from concentrated wastewater AIM: Optimize energy recovery of an AnMBR treating wastewater concentrated with FO. Effect of dynamic change of temperature and HRT • MAIN FINDINGS: • The temperature and the input-substrate ratio influence the production of methane in anMBR treating synthetic FO concentrated domestic ww • Lower temperatures led to higher lag phases and lower maximum methanogenic activity, with different final cumulative CH4 produced • Results of dissolved CH4 in the AnMBR did not change with temperature not confirming results from the BMP tests

  16. MAIN FINDINGS & NEXT TARGETS 2 ENERGY production from concentrated wastewater AIM: Optimize energy recovery of an AnMBR treating wastewater concentrated with FO. Effect of dynamic change of temperature and HRT • NEXT TARGETS: • Operate with real concentrated wastewater (semi-industrial FO process with 70% water recovery) • HRT from 40 to 10 hours • switching among15, 23 and 34 ºC • Comparison of MgCl2 and NaCl as draw solution

  17. MAIN FINDINGS & NEXT TARGETS 3 Value-added products generation with electrochemical system AIM: Electrochemical control and minimization of H2S formation in anaerobic systems to avoid partial inhibition of methanogenic activity

  18. MAIN FINDINGS & NEXT TARGETS 3 Value-added products generation with electrochemical system • MAIN FINDINGS: • Electrodes of activated carbon and graphite were efficient for sulfide removal in the anMBR at low sulfide concentrations • Different electrochemical sulfur recovery strategies were successfully applied to minimize electrode passivation

  19. MAIN FINDINGS & NEXT TARGETS 3 Value-added products generation with electrochemical system • NEXT TARGETS: • Test other precursors and surfactants (MnSO4 and H2SO4 at 1,6V at 95 ˚C are not very attractive for scaling up) • Test stability of MnOx under anodic and cathodic polarization in the batch cell • For coupling with AnMBR, another substrate should be used, probably Ti mesh

  20. MAIN FINDINGS & NEXT TARGETS 4 Evaluate the impact on the WWTP downstream AIM: Optimize the nitritation/denitritation pathway to remove nitrogen and phosphorus in the presence of wastewater with a low chemical oxygen demand (COD) content and minimize N2O production.

  21. MAIN FINDINGS & NEXT TARGETS 4 Evaluate the impact on the WWTP downstream • MAIN FINDINGS: • The impact of sewer mining on downstream centralized wastewater treatment has been quantified • Lack of denitrifying P removal exhibited by the abundant polyphosphate accumulating organism Tetrasphaera, suggesting that this organism is not useful for achieving simultaneous EBPR and N removal via the nitrite pathway

  22. MAIN FINDINGS & NEXT TARGETS 4 Evaluate the impact on the WWTP downstream • MAIN FINDINGS: • The impact of sewer mining on downstream centralized wastewater treatment has been quantified • Lack of denitrifying P removal exhibited by the abundant polyphosphate accumulating organism Tetrasphaera, suggesting that this organism is not useful for achieving simultaneous EBPR and N removal via the nitrite pathway • Aeration rate should be considered to be an important parameter impacting N2O emissions, independently of the DO concentration; • Higher loading rate of nutrients and COD (high season) was not as important a contributor to N2O emissions as compared to the aeration rate

  23. MAIN FINDINGS & NEXT TARGETS 4 Evaluate the impact on the WWTP downstream • NEXT TARGETS: • Evaluate the impact of an increase in saline concentration in wastewater on nitrogen removal and N2O emissions in the WWTP

  24. MAIN FINDINGS & NEXT TARGETS 5 Modelling and system optimization AIM: Develop a set of mathematical models describing some of the innovative processes to foster their integrated optimization

  25. MAIN FINDINGS & NEXT TARGETS 5 Modelling and system optimization • MAIN FINDINGS: 3 models • Integrated urban wastewater model: catchment, sewer, wwtp, receiving media • Plant wide model: description of P, S, Fe cycles within water and sludge line • General electrochemical system: applicable to electro-dialysis, electro-concentration and electro-conversion

  26. MAIN FINDINGS & NEXT TARGETS 5 Modelling and system optmization • NEXT TARGETS: • Further model testing with project partner data (model validation is very important) • Model development of remaining process units • Packaging of the different software tools in one prototype • Generation and simulation of different scenarios to evaluate overall process performance • Freely distribute software

  27. MAIN FINDINGS & NEXT TARGETS 6 Decision support system AIM: Develop a multi-criteria DSS based on the developed models and knowledge acquired for planning of integrated centralised/decentralised UWS • No findings yet... Next targets working group (experts, AB, stkh...) • qualitative pros and cons of each technology • cost, energy consumption, environmental impact estimation • potential interactions • alternative technologies for sewer mining • criteria list for the MCDA • define dynamic scenarios • perform simulations
