Biological trickling filters are widely used for sewage treatment. This study models a biological filter based on an anaerobic–anoxic–oxic process (A2O–BTF), established by combination of aerobic and anaerobic technology. The performance operational parameters were analyzed using Sumo, commercially available wastewater treatment (WWTP) simulation software. the conventional three-stage (Three-St...
Background and Aim: Electrospun nanofibers can be used to produce filter media in personal protective equipment for the military. The present study aimed to optimize the electrospinning process used to create polyurethane nanofiber substrates and compare the optimum substrate filtration performance with a typical commercial substrate used in the structure of N95 respirators. Methods: In this ex...
Liquid spreading through a randomly packed particle-resolved bed influenced by capillary or inertial ( $AB_s \sim 1$ ), and gravitational force (moderately 0.1$ ) strongly 0.01$ )) is investigated using the volume-of-fluid simulations. The relative contribution of governing forces at different stages analysed time evolution Weber $We_I$ $AB_I$ numbers. We show that dynamics liquid primarily gov...
Abstract This study is about the effectiveness of wastewater treatment technologies in two plants at Mangaung Municipality South Africa. The removal FOG, nitrogen and phosphorus an important component treatment. Therefore, aims investigating (biological trickling filter activated sludge) studied.
