Ultraviolet treatment has emerged as a cost-effective solution for producing clean and potable water of optimal quality, especially in regions where access is challenging and critical. UV water treatment is a sophisticated process that necessitates the collaboration of multidisciplinary teams to address scientific aspects. The implementation of control systems faces challenges, including non-linearity, uncertainty, and latency. Given the significance of water treatment through UV radiation and the imperative to ensure water quality, it is crucial to control both the lamp intensity (UVDose) and the water flow. The main objective of this article is to implement a sliding mode control law and state feedback for the motor of the centrifugal pump using the Bond Graph approach. The aim is to regulate the motor speed and, consequently, the water flow rate. This enables the influencing of the bacteriological attack time of the water, where the exposure time of water to the UV lamp determines the treatment result. The experimental results obtained, along with a comparative study, have allowed us to emphasize the robustness of sliding mode control in comparison to state feedback control. These studies were conducted following parametric variations applied to the different parameters of the motor pump.

However, overreliance on nitrogen (N) and phosphorus (P) fertilizers has led to environmental degradation, including eutrophication and inefficient nutrient use, raising sustainability concerns. This study aims to develop a biochar-supported controlled-release fertilizer (BAPF) containing N and P, and evaluate its impact on soil nutrient dynamics, nutrient recovery, plant growth, and yield. BAPF was synthesized by impregnating biochar derived from oat hulls with urea and diammonium phosphate. An eight-week soil incubation experiment compared nutrient release dynamics between BAPF, conventional fertilizers (CF), oat hull biochar (OHB), and a control (CT). BAPF demonstrated consistent nutrient release, maintaining higher N and P availability over time than CF. By day 60, total N concentration in the BAPF treatment was 6 % higher than CF, while P availability was consistently 20 % higher. BAPF also exhibited lower ammonification rates compared to unfertilized treatments, while nitrification rates were 2.6 times greater compared to OHB and CT, demonstrating enhanced nitrogen conversion efficiency. In a greenhouse trial using spring wheat as a model plant, BAPF improved growth, nutrient uptake, and grain yield compared to CF, OHB, and CT. Total biomass and grain yield increased by approximately 15 % relative to CF, and nutrient recovery rates were significantly higher, with N apparent recovery (ARN) of 55.0 % compared to 36.5 % for CF. Additionally, the apparent P recovery rose from 8.9 % in CF to 18.5 % in BAPF. The findings suggest that BAPF improves nutrient use efficiency and enhances grain productivity compared to conventional methods. Its controlled-release properties lead to longer nutrient availability, better nutrient recovery, and increased crop productivity, even in high P-fixing soils. Therefore, BAPF offers an effective alternative to reduce reliance on synthetic fertilizers, enhancing sustainability in agricultural systems.</div></div>","PeriodicalId":11725,"journal":{"name":"Environmental Technology & Innovation","volume":"39 ","pages":"Article 104269"},"PeriodicalIF":6.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144115064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leveraging the principles of the MICP, it was observed that when urea concentration was reduced to 0.7 M, by replacing it with bicarbonate, surface strength was close to 400 kPa. Furthermore, wind tunnel testing showed a significant reduction in dust emission, where the mass loss rate of the biocemented sample was below 10 kg m⁻<sup>2</sup> h⁻<sup>1</sup>, which means a 9-fold reduction compared to untreated samples. So, it was demonstrated that bicarbonate can effectively replace urea, achieving a relevant reduction of up to 75 % in urea use without compromising the surface strength of the biocemented tailings and reducing the environmental hazards of ammonia release.

Previous studies have examined individual factors affecting TP, but the combined impacts of anthropogenic activities and climate factor remain unclear. This study analyzed TP data from 636 sites in the YRB during 2016–2020 using partial least squares structural equation modeling to assess these combined effects on TP pollution. Results showed government regulation significantly reduced TP concentration from 2016 to 2020. Anthropogenic activities, including changes in landscape, GDP, and population growth, significantly influenced TP concentrations. Cropland and impervious surfaces were major TP sources, while forests acted as effective TP sinks. Landscape fragmentation weakened the ability of source landscapes to export TP to water bodies and the purification capacity of sink landscapes, while aggregation enhanced sink capacity. GDP and population growth were positively correlated with TP, but their impacts were partially mitigated by landscape adjustments and policy interventions. Climate factor also significantly affected TP concentrations. Precipitation influenced surface runoff and pollutant generation, playing a key role in non-point source pollution and amplifying the positive impact of landscape sources on TP. Air temperature promoted the release of internal phosphorus by affecting water temperature, water body stratification, and dissolved oxygen concentrations. Wind speed could weaken the release of TP from landscape sources to water bodies.
