Municipal wastewater treatment plants (MWWTPs) are essential infrastructures in any urban context, but they may be considered as a potential source of greenhouse gas (GHG) emissions and should be coherent with European Union (EU) policy on energy efficiency. This study presents a sustainability evaluation of four Italian and Romanian MWWTPs in terms of energy efficiency and greenhouse gas emissions using Energy Performance and Carbon Emissions Assessment and Monitoring (ECAM) tool software. The obtained results indicated that biogas recovery improved energy performances, while the largest contributions in terms of GHG emissions were in all cases caused by energy consumption and methane produced during wastewater treatment. The Romanian plants exhibited higher GHG emissions, compared to the Italian plants, mainly because of the different values of national conversion factors for grid electricity (0.41 kg CO2/kWh for Italy and 1.07 kg CO2/kWh for Romania). Two scenarios aimed at enhancing the overall sustainability were hypothesized, based on increasing the serviced population or energy efficiency, achieving significant improvements. A sustainability assessment of MWWTPs should be adopted as a useful tool to help water utilities to introduce low-energy, low-carbon management practices as well as being useful for policy recommendations.

Assimilation Capacity

Cíle udržitelného rozvoje OSN požadují mimo jiné i zlepšit kvalitu vody snížením jejího znečišťování, zamezením vyhazování odpadů do vody a minimalizací vypouštění nebezpečných chemických látek do vody. Jedním z nástrojů, který lze využít pro posouzení udržitelnosti vypouštění znečištění do vod je vodní stopa. V článku je popsána analýza šedé vodní stopy velkých komunálních čistíren v povodí Ohře. Pro analýzu byly vybrány komunální čistírny odpadních vod uvedené státním podnikem Povodí Ohře ve zprávách vodohospodářské bilance. Byla stanovena asimilační kapacita toku pro jednotlivé znečišťující látky hlášené provozovateli čistíren odpadních vod pro účely vodohospodářské bilance, spočtena šedá vodní stopa látek vstupujících na čistírnu odpadních vod (produkované znečištění) a vypouštěných do recipientů v odpadní vodě. Posouzení udržitelnosti bylo provedeno k dlouhodobému průměrnému průtoku recipientem. Analýza ukázala, že asimilační kapacita vodních toků je nejvíce vytěžována vypouštěním celkového fosforu a amoniakálního dusíku. Zároveň z analýzy vyplynulo, že čistírny odpadních vod, až na výjimky, čistí vodu dostatečně a asimilační kapacita vodního toku nebývá vyčerpána. ----------- The Sustainable Development Goals (SDGs), adopted by all United Nations Member States in 2015, call, among others, for the improvement of water quality by reducing water pollution, avoiding waste disposal in water and minimizing hazardous chemicals discharge into water. One of the tools that can be used for the sustainability assessment of pollution discharge into water is the water footprint. The paper calculates the grey water footprint of large municipal wastewater treatment plants in the Ohře River basin, located in the Czech Republic. Municipal wastewater treatment plants listed by the state-owned enterprise Povodí Ohře in Water Balance Management reports were selected for the analysis. The receiving body assimilation capacity for individual pollutants was determined and the grey water footprint at the inlet and outlet of the WWTP was calculated. Subsequently, the sustainability assessment of the WWTP discharges were carried out and related to the long-term average flow rates in the receiving water body. The analyses showed that the assimilation capacity of the watercourse is mostly utilized by the discharge of total phosphorus and ammonia nitrogen. The analysis also showed that (with some exceptions) the wastewater treatment plants treat water sufficiently and the assimilation capacity of the watercourse is not exhausted.

Abstract:Phosphorus is a major substance that is needed especially for agricultural production or for the industry. At the same time it is an important component of wastewater. At present, the waste management priority is recycling and this requirement is also transferred to wastewater treatment plants. Substances in wastewater can be recovered and utilized. In Europe (in Germany and Austria already legally binding), access to phosphorus-containing sewage treatment is changing. This paper dealt with the issue of phosphorus on the sewage treatment plant in Nitra. There are several industrial areas in Nitra where record major producers in phosphorus production in sewage. The new wastewater treatment plant is built as a mechanicalbiological wastewater treatment plant with simultaneous nitrification and denitrification, sludge regeneration, an anaerobic zone for biological phosphorus removal at the beginning of the process and chemical phosphorus precipitation. The sludge management is anaerobic sludge stabilization with heating and mechanical dewatering of stabilized sludge and gas management. The aim of the work was to document the phosphorus balance in all parts of the wastewater treatment plant - from the inflow of raw water to the outflow of purified water and the production of excess sludge. Balancing quantities in the wastewater treatment plant treatment processes provide information where efficient phosphorus recovery could be possible. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. There are also two outflows - drainage of cleaned water to the recipient - the river Nitra - 9.9 kg Ptot/day and Ptot content in sewage sludge - about 120.3 kg Ptot/day - total 130.2 kg Ptot/day.
