The stations were situated upstream (S1), in front (S2) and downstream (S3) from the discharge of urban wastewater from the town of Azemmour, which is discharged directly without treatment near the estuary mouth. The selection of these stations appeared appropriate to assessing the quality of the waters, which are influenced by both marine hydrodynamics resulting from very low freshwater inflows and sewage discharges. Monitoring of several parameters, including temperature, pH, dissolved oxygen, conductivity, salinity, turbidity, as well as the content of chlorophyll a and pheopigments, enabled the examination of the impact of marine hydrodynamics and the and the specific characteristics of the three surveyed stations. The analyses were performed using R software version 4.2.0. The results obtained indicate that the studied physico-chemical and biological parameters exhibited variations with significant correlations. Statistical approaches allowed the determination of profiles for stations S1, S2 and S3. It is evident that S1 (located slightly far from the discharge) showed a profile that tended to differ from the other two stations, S2 and S3, especially for certain parameters (temperature, pH, turbidity, and chlorophyll a ). On the other hand, all stations were impacted to some extent by the discharge of wastewater during rising tides. The present study can serve as an assessment tool to support decision-making regarding the physico-chemical quality of the waters of the Oum Er Rbia estuary.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"12 9","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139126712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methods of main cultivation in the sunflower agrocenosis of grain-row crop rotation had a major influence on the soil structuring processes. The use of moldboard and no-moldboard tillage increased the number of the most agronomically beneficial aggregates (0.25–10 mm) in the 0–10 cm soil’s layer at the begin - ning of the sunflower growing season by 6.0% compared to shallow no-moldboardof tillage the soil. By the end of the growing season in the sunflower agrocenosis in the 0–30 cm soil layer, compared to the beginning of the crop growing season, the number of agronomically beneficial aggregates (0.25–10 mm) decreased, the number of frac - tions larger than 10 mm and fractions smaller than 0.25 mm increased. The coefficient of structure for moldboard and no-moldboard tillage significantly increased compared to shallow no-moldboardof tillage. The use of shallow no-moldboardof tillage and moldboard with no-moldboardof tillage was led to an increase in the content of stable aggregates by 1.2–7.5%. The highest yield of sunflower was recorded for the use of moldboard with no-mold - boardof tillage – 2.72 t/ha, which is significantly higher than other variants. The use of shallow no-moldboardof tillage for 10–12 cm with disc tools led to a notable decrease in productivity compared to the control. Improving the water resistance of soil aggregates during moldboard and no-moldboard tillage and shallow no-moldboardof tillage helps to preserve the soil’s potential fertility.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"16 12","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139125972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, waste absorption ef - ficiency varies between species. This research aims to analyze the most efficient seaweed as bioremediation of intensive waste ponds. The method used in this research was three types of seaweed stocked based on treatment groups in each of three tanks measuring 100×100×100 cm made of bamboo, wood, and specially designed tar-paulin. This study was carried out on a laboratory scale for 42 days on three local seaweed species to evaluate the waste disposal efficiency of each seaweed species. This research was conducted at the Bone Marine and Fisheries Polytechnic Laboratory, Tulang Daerah, South Sulawesi Province, Indonesia, from September to October 2022. Measurement of ammonia (NH 3 -N), nitrite (NO 2 -N), nitrate (NO 3 -N), and phosphate (PO 4 -P) carried out at the Center for Brackish Water Aquaculture and Fisheries Extension in Maros, the concentrations of the four nutrient wastes were significantly different (P<0.05), indicating differences in nutrient removal for each seaweed species. The removal efficiency of NH 3 -N, NO 2 -N, NO 3 -N, and PO -P by G. verrucosa (97.1, 99.7, 99.9, 99.7%) was significantly higher (P<0.05) compared with E. spinosum (90.5, 93.9, 96.4, 95.4%) and K. alvarezii (81.6%, 94.6%, 94.5%, and 95.4%, respectively). Meanwhile, E. spinosum was not significantly different (P>0.05) from K. alvare-zii in removing NO 2 -N, NO 3 -N, and PO 4 -P but was more efficient in reducing NH 3 -N. Overall, G. verrucosa is the most efficient in intensive disposal of shrimp pond waste based on the results of this study.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"14 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139128091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is produced from carbon-rich materials, mainly fossil raw materials. However, the price of hard coals has increased significantly in recent years due to the COVID-19 pandemic and the war in Ukraine. The existing eastern markets became blocked for carbon-raw-material sourcing. It is therefore important to find alternative materials or plant-based products. This study investigated the possibility of manufacturing activated carbon from waste biomass such as sugar beet fibers (SBSF), mixed vegetable processing waste (mainly corn) (MVW) and cherry stones (ChS). The raw material was subjected to pyrolysis, milling, granulation, carbonisation and activation at different times and temperatures. However, of the biomass materials tested, only SBSF in the form of marc can be processed into valuable activated carbon in further production steps. MVW and ChS as carbon substrates showed, in addition to high moisture and ash, low efficiency in decolourising molasses and methylene blue MB and also had a lower specific surface area.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"4 6","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139126413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After costly treatment processes, water taken from surface and underground intakes is used and then largely discharged to receivers in the form of treated wastewater. Advanced wastewater treatment methods ensure that the treated wastewater is characterized by very low physical and chemical pollution, sometimes better than the water quality in the receiving basin. The research was conducted under a cooperation agreement between Bialystok University of Technology and Bialystok Waterworks Ltd. The recovery of water from wastewater was one of the topics pursued.This paper analyzes the parameters of treated wastewater from the largest municipal wastewater treatment plant in the Podlaskie Province. The analysis of the treated wastewater composition was based on monitoring studies conducted by the company Bialystok Waterworks Ltd. between 2020 and 2023. The analysis concerned the basic parameters of wastewater, namely the content of organic matter and total suspended solids.This was due to the requirements for the recyclability of treated wastewater. Linear modeling was performed to determine if a sufficiently strong correlation was detected;otherwise output distribu - tion characteristics were provided.In all cases, the output concentrations were far below the class A limits for irrigation in the whole research period.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"41 3","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139127359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fur - thermore, the effects of their key operating factors were determined. To achieve this goal, an electrocoagulation re - actor coupled with a magnetic-field generator was used and the response surface methodology was applied through a Box-Behnken experimental design. Here, current intensity (I), treatment time (T), and ozone concentration (O 3 ) are considered the influencing factors. Likewise, the removal percentages of COD and TSS serve as response indicators. The results indicate that T, I, and O 3 are significant for the removal of COD and TSS at a confidence level of p-value < 0.05. For COD, the optimal operating conditions are I = 6.8 A, T = 30 min, and O 3 = 10 mg/l; and for TSS, the optimal conditions are I = 5.72 A, T = 28 min, and O 3 = 7.8 mg/l. These conditions yield removal efficiencies of 41.8% for COD and 97.9% for TSS. The findings suggest that integrating these technologies is a viable alternative for mitigating the pollution issues caused by the tannery industry.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"48 25","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139125599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
