Finland and Poland share similar environmental interests with regard to their wastewater effluents eventually being discharged the Baltic Sea. However, differences in influent characteristics, treatment processes, operational conditions, carbon intensities of energy mixes both countries make these two interesting for footprint (CF) comparison. This study aimed at proposing a functional unit (FU...

This study presents the results of random testing selected on-site wastewater treatment plants (WWTPs) constructed in Poland Masovia Voivodship years 2011–2016. The vast majority tested WWTPs were compact (container) type plants, based on low rate activated sludge (AS), sequencing batch reactors (SBR), or a hybrid (activated supported with biological film, AS + BF) method. Compact plans are bec...

Modernisation of municipal and industrial wastewater treatment plants (WWTPs) should be carried out, taking into account its impact on global warming, e.g., through carbon footprint (CF) analysis. An important sector in Poland is the dairy industry. In WWTPs, aerobic sewage sludge stabilisation applied thus far being replaced by anaerobic process. This change positive due to possibility energy ...

Municipal wastewater treatment plants (WWTPs) play an indispensable role in improving environmental water quality urban areas. Existing WWTPs, however, are important source of greenhouse gas (GHG) emissions and may not be able to treat increasingly complicated or meet stringent standards. These WWTPs can updated address these challenges, different technologies available but with potentially imp...

An important part of the environmental degradation is caused by discharge untreated or mistreated wastewater. Since centralized treatment systems have proved to be inefficient, tackling issues requires a regional approach. Wastewater plants (WWTPs) mitigate impacts and contribute financial savings other firms. However, literature evaluating WWTPs' performance economic sustainability does not ab...

Biogas is a proven and valuable energy source today for combined production of heat and electricity (CHP). In this paper, a novel CHP system installation based on a 500 kW micro humid air turbine (mHAT) in a wastewater treatment plant (WWTP) is presented and discussed. Furthermore, some considerations regarding an appropriate biogas treatment system and heat recovery module is discussed. The re...

In 1990, the private company Aquafin was founded and assigned with the task of the design, construction, operation and financing of the necessary infrastructure for sewage treatment. One of the challenges Aquafin is facing now is to upgrade the patrimonium of old municipal wastewater treatment plants (WWTPs). These plants need to be retrofitted towards strict phosphorus and nitrogen removal con...

Seven small wastewater treatment plants were chosen for evaluation. These WWTPs work on the principle of anaerobic pre-treatment and aerobic post-treatment and were made with the cooperation of Slovak Technical University with ASIO-SK s.r.o. Bytča and ASIO s.r.o. Brno. Wastewater treatment plants are made for 5-600 PE. When operated at suitable conditions, the results match the directive water ...

This paper presents a brief review of the international scientific literature of polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) in sewage sludge and a survey of these compounds in sewage sludge from 16 Australian wastewater treatment plants (WWTPs). The SigmaPBDE mean concentration in the Australian study was 1137microgkg(-1) dry weight (d.w.) (s.d. 1116) and ranged ...

A comprehensive survey of the occurrence of organic compounds in 30 wastewater (WW) effluent samples from 21 urban wastewater treatment plants (WWTPs) from both secondary and tertiary treatments was carried out in the Mediterranean and Atlantic basins of the Andalusia region (south of Spain). For each sample, a total of 226 compounds including pesticides and some transformation products, polycy...
