Efficient characterization of wastewater stream quality is vital to ensure the safe discharge or reuse treated (WW). There are numerous parameters employed characterize water quality, some required by directives (e.g. biological oxygen demand (BOD), total nitrogen (TN), phosphates (TP)), while others used for process controls flow, temperature, pH). Well-accepted methods assess these have traditionally been laboratory-based, taking place either off-line at-line, and presenting a significant delay between sampling result. Alternative can run in-line on-line, generally being more cost-effective. Unfortunately, often not accepted when providing information regulatory bodies. The current review aims describe available laboratory-based approaches compare them with innovative real-time (RT) solutions. Transitioning from RT measurements means obtaining valuable data, avoiding time delays, possibility optimize (WW) treatment management. A variety sensor categories examined illustrate general framework in which applications replace longer conventional processes, an eye toward potential drawbacks. enhancement be achieved through employment advanced soft-sensing techniques Internet Things (IoT), coupled machine learning (ML) artificial intelligence (AI).

Bridging the divide between inland water quantity and quality with satellite remote sensing: An interdisciplinary review

Wiley Interdisciplinary Reviews Water, Год журнала: 2024, Номер 11(4)

Опубликована: Март 10, 2024

Abstract The quantity and quality of surface water are inherently connected yet overwhelmingly studied separately in the field remote sensing. Remotely observable (e.g., extent, elevation, lake/reservoir volume, river discharge) color, turbidity, total suspended solids, chlorophyll a , colored dissolved organic matter, temperature) parameters inland waterbodies interact through series hydrological biogeochemical processes. In this review, we analyzed trends sensing publications to understand prevalence studies on versus open‐surface (rivers, streams, lakes, reservoirs) as well identified opportunities for integrating both future work. Our bibliometric analysis found that despite increasing number using waterbodies, few date have used tools or approaches simultaneously study quality. Ultimately, by providing insights into potential integration studies, aim identify pathway advance understanding dynamics freshwater resources This article is categorized under: Water Life > Methods Science Quality Nature Freshwater Ecosystems

Опубликована: Ноя. 2, 2023

Remote sensing plays a crucial role in modeling surface water quality parameters (WQPs), which aids spatial and temporal variation assessment. However, existing models are often developed independently, leading to uncertainty regarding their applicability. This study focused on two primary objectives. First, it aimed evaluate different for chemical oxygen demand (COD), total phosphorus (TP), nitrogen (TN), suspended solids (TSS) body, the J. A. Alzate dam, Mexican highland region (R2 ≥ 0.78 RMSE ≤ 16.1 mg/L). The were estimated using multivariate regressions, with focus identifying dilution dragging effects inter-annual flow rate estimations, including runoff from precipitation municipal discharges. Second, sought analyze potential scope of application these other bodies by comparing mean WQP values. Several exhibited similarities, minimal differences values (ranging −9.5 0.57 mg/L) TSS, TN, TP. These findings suggest that certain may be compatible enough warrant exploration joint future research endeavors. By addressing objectives, this contributes better understanding suitability remote sensing-based characterizing quality, both within specific locations across bodies.
