Article Synopsis
- The study aims to create a model for predicting the long-term performance of High-Rate Activated Sludge (HRAS) processes, focusing on removing carbon, nitrogen, and phosphorus.
- The model builds on existing Activated Sludge Models (ASM1 and ASM3) and includes important mechanisms like adsorption and substrate storage, following a detailed calibration process with data from a pilot HRAS plant.
- The model achieved over 70% prediction efficiency for several key metrics, but identified uncertainties, especially in soluble COD estimates, attributed to variations in wastewater characteristics not fully accounted for in the model.
Article Synopsis
- Coagulants from water treatment plants typically produce sludge that is often sent to landfills, but utilizing this sludge is encouraged for sustainability.
- This study explores using WTP sludge, specifically iron sludge, as a substitute for conventional coagulants in a high-rate activated sludge system, finding it enhances treatment efficiency.
- The addition of iron sludge improved particulate chemical oxygen demand removal and sludge settleability, while also reducing overall operational costs by 11%, indicating potential benefits for both water treatment facilities and environmental sustainability.
Malachite green (MG), an antibiotic with antifungal activity, is illegally used in aquaculture. Given that this chemical is teratogenic and mutagenic, abstinence from intake seems to be a need for public safety. The goal of this systematic review and meta-analysis was to determine the global contamination of fishes by MG and its reduced metabolite, leucomalachite green (LMG), in a number of marine and farmed fish species.
View Article and Find Full Text PDFAcute kidney injury (AKI) may have a negative effect on mitochondrial hemostasis and bioenergetics as well as coenzyme Q (CoQ) content. PGC-1α, AMPK, sirtuin 1 (Sirt1), and Sirt3, as the key metabolic regulators under nutritional stress, stimulate energy production mitochondrial biogenesis during AKI. However, no report is available on the relationship between CoQ level and nutrient sensors in the pathophysiology of AKI caused by scorpion envenomation.
