“…This assessment can be done on an approximate basis, based on, among other things, the simplified balance of macroelements and based on their use (phytoremediation). Earlier studies by Antonkiewicz et al [9] as well as by Bien et al [16] confirm the need to understand the cycling and the use (recycling) of elements from organic waste.…”

“…Sludge coming from rural sewage treatment plants that receive mainly domestic wastewater can be useful in cultivation of cereals intended for consumption, feed or energy purposes. As a rule, municipal sewage from rural sewage systems is not burdened with chemical contaminants, and after purification, the obtained sewage sludge will be "pure" in terms of heavy metals and not burdened with microbiological contaminants [16,17].…”

Municipal sewage sludge from rural sewage treatment plants is characterized by a substantial content of organic matter and macronutrients, which can be used in cultivation of cereals. In a farm located in the commune of Iwanowice in the south of Poland (Malopolska province), municipal sewage sludge was applied under spring wheat cultivation. The experiment was set up on heavy soil with slightly acid reaction and medium content of available forms of P, K, Mg. Application of sewage sludge in a dose of 23 Mg fresh matter per hectare (4.21 Mg d.m.) led to no significant changes in chemical properties of the soil. Application of sewage sludge significantly increased yield of spring wheat. That increase led to a significant decrease in the content of N, P, K, Na, Mg and Ca in spring wheat. Utilization of N, Mg, K, P and Ca from sewage sludge by spring wheat was at a level of 82, 63, 44, 36, 9 %, respectively, of the amount introduced with the waste. Application of municipal sewage sludge significantly decreased the value of Ca : P ratio in spring wheat grain and straw. The sewage sludge did not cause a significant change in the values of Ca : Mg, K : Na, K : (Ca+Mg), K : Mg and K : Ca ratios in spring wheat grain and straw. Municipal sewage sludge can be used environmentally, including for fertilization of cereals, provided that environmental standards are kept.

“…A regulation implemented in 2016, according to which the disposal of municipal wastewater sludge on a landfill is banned, resulted in an increased interest in other, more pro-ecological methods of sludge management [7]. The most popular methods of sludge management include use in agriculture for the cultivation of non-consumption crops, reclamation and adjustment of soil to a particular application, the production of compost, the use of sludge (after incineration) in the building industry, the production of adsorbents for industry, and thermal utilization [8,9]. In order to provide safety, the introduction of sludge to soil must be preceded by its dewatering, stabilization, and composting.…”

The Use of Artificial Neural Networks and Decision Trees to Predict the Degree of Odor Nuisance of Post-Digestion Sludge in the Sewage Treatment Plant Process

This paper presents the application of artificial neural networks and decision trees for the prediction of odor properties of post-fermentation sludge from a biological-mechanical wastewater treatment plant. The input parameters were concentrations of popular compounds present in the sludge, such as toluene, p-xylene, and p-cresol, and process parameters including the concentration of volatile fatty acids, pH, and alkalinity in the fermentation sludge. The analyses revealed that the implementation of artificial neural networks allowed the prediction of the values of odor intensity and the hedonic tone of the post-fermentation sludge at the level of 30% mean absolute percentage error. Application of the decision tree made it possible to determine what input parameters the fermentation feed should have in order to arrive at the post-fermentation sludge with an odor intensity <2 and hedonic tone >−1. It was shown that the aforementioned phenomenon was influenced by the following factors: concentration of p-xylene, pH, concentration of volatile fatty acids, and concentration of p-cresol.

“…SS management is one of the most difficult and challenging tasks of wastewater treatment plants due to its high content of water, poor dewaterability, and strict regulations for its disposal . SS treatment processes in treatment plants are compaction, stabilization, conditioning, dehydration, hygienization, and lastly drying . Although, the volume of SS is only 1–2% of the treated wastewater volume, its management is highly complicated and has a cost of 20–60% of the total operating costs of the plant …”

Burning behavior of fuel blends consisted of lignite samples and waste biomass species such as sewage sludge (SS) and refuse‐derived fuel (RDF) was studied. The blends where the wastes account for 5, 10, and 15 wt% were burned in a thermal analyzer up to 900°C. The nonisothermal burning kinetics were established using Borchardt and Daniels method that bases on the data obtained from differential scanning calorimetry. The maximum rate of combustion (Rmax), the peak temperature (TR‐max), the ignition temperature (Tign), and the burnout temperature (Tb) that predicts the thermal reactivity were considered to evaluate the effects of RDF and SS on the burning characteristics of the lignite samples. It was determined that the combinations of the additive behavior and the synergistic interactions govern the burning characteristics of the fuel blends. The thermal reactivity of the samples can be arranged in the order of RDF > lignite > SS. On the other hand, blending of RDF or SS with the lignite samples did not led to any significant segregation in the heat flow characteristics, and can be concluded that these wastes can be safely burned with lignite.
