“…The process of autermic trimophilic stabilisation makes it possible to obtain sludge that does not rot and is free of pathogenic microorganisms, parasites and fungi (Bartkowska, 2014;Bartkowska, 2015). It significantly contributes to minimising the amount of sewage sludge and allows the production of organic fertiliser instead of waste Bartkowska & Dzienis, 2019). The spontaneous acquisition of high temperatures also allows for recovery and manage excess thermal energy.…”

The article aimed to analyze the concept of modernisation of sludge management prepared for an exemplary sewage sludge treatment plant. Four variants of solutions, based on different processes, aerobic (oxygenic), anaerobic or – aerobic – anaerobic, were discussed. The article presents the characteristics of essential elements of the proposed solutions. The technical and technological parameters of each of the variants are exposed. The expected capital expenditure and basic operating costs are presented. A cost-effectiveness analysis of the options has also been carried out. The analysed technological processes ensure obtaining hygienically and sanitary safe end products. They contribute significantly to minimising the amount of sewage sludge. The most economically efficient, with the lowest average annual costs, is the variant with the application of anaerobic thermo-philic-mesophilic sludge stabilisation. The highest average annual costs were obtained for the variant with drying and incineration of sludge.

Carbon emissions from non-renewable energy consumption account for 38 percent to 50 percent of conservatory smoke production in the world, and wastewater treatment plants happen to be one of the most significant drivers of orangery vapor discharges universally. So, to meet the target of achieving a significant reduction of carbon pollution in 2030, we must focus on energy savings and Waste Water Treatment Plant consumption reduction. The demand for future urban wastewater Treatment Plant construction and technical enhancements remains high. The energy ingestion of treatment plants is related development of influent plants, effluent standards, and so on. This study is meant to offer directions for emerging new strategies to facilitate the reduction of water scarcity now and in the future as a powerful and reliable form of treating wastewater technology in particular. This current study keeps its focus on the stimulus of guiding principle on treatment plant structure using scenario-based investigation. This article focuses on approaches used for water purification and the level of energy used. This research analyses the viability of energy self-sufficiency by examining existing energy consumption efficiency. It also investigates the water-energy link in plants and the sustainable approach to solving water scarcity problems, thereby providing the academic source for improving energy management systems and the formulation of energy policy and infrastructures. The research finds out that renewable energy is eco-friendly and is not regenerated by human efforts, nor does it emit any harmful gases into the atmosphere that could contribute to global warming, and it also notes that it is one of the major solutions to water scarcity problems now and later.

“…One of the methods of changing sewage sludge into biomass that can be used naturally is Autothermal Thermophilic Aerobic Digestion (ATAD). The process ensures complete stabilisation and sanitisation of the sludge and reduces its solid content [3,4]. It is an effective method that runs in a fully automated hermetic installation, does not require the use of enrichment materials (unlike, for example, composting), and requires a small area for the construction of the installation [5].…”

The study presents the research results on the rejected water generated in dewatering sludge stabilised in Autothermal Thermophilic Aerobic Digestion (ATAD) technology. The research was carried out in three municipal wastewater treatment plants (WWTPs), with a capacity of 1500 to 3260 m3 d−1 and a sludge node capacity of 835 to 2000 kg DM d−1. The mean content of Kjeldahl nitrogen (TKN) in the rejected water samples taken from each object ranged from 485 to 1573 mg N L−1, ammonium nitrogen 318 to 736 mg N L−1, and the average concentration of total phosphorus ranged from 96 to 281 mg P L−1. The average content of organic matter expressed as five-day biological oxygen demand (BOD5) ranged from 205 to 730 mg O2 L−1, while chemical oxygen demand (COD) ranged from 767 to 4884 mg O2 L−1. The study determined the kinetics of the biochemical decomposition of organic matter, assuming that it follows the first-order equation. The average reaction rate constant k in subsequent treatment plants was estimated at 0.424, 0.513 and 0.782 d−1. The R2 coefficient determining the model’s adjustment to empirical values was not lower than 0.952. The organic matter biodegradability index average values ranged from 0.17 to 0.26.
