In deammonification systems, nitrite-oxidizing bacteria (NOB) suppression and nitrous oxide (N2O) mitigation are two important operational objectives. To carry out this multivariable analysis of response, a comprehensive model for the N cycle was developed evaluated against experimental data from laboratory-scale granular sludge sequencing batch reactor. Different aeration strategies were tested, manipulated variables comprised dissolved oxygen (DO) set point in aerated phase, on/off...
The production of sodium hypochlorite (NaOCl) from salty wastewater using an electrochemical cell has several advantages over other methods that often require hazardous chemicals and generate toxic waste, being more sustainable environmentally friendly. However, the process producing requires careful control operating conditions, such as current density, flow rate, inert electrode spacing, electrolyte concentration, to optimize conversion efficiency prevent fouling degradation. In this...
The growing urban wastewater volume poses a major global environmental challenge, especially in developing nations where inadequate treatment and discharge impact clean water availability. This study focused on Setiu Wetland, aiming to analyze seasonal spatial variations of trace metals particulate form from anthropogenic pathogenic sources. Surface samples were collected multiple stations, measuring physical parameters like salinity, temperature, pH, dissolved oxygen (DO), organic carbon...
A mechanistic model was developed as an extension of the Activated Sludge Model No. 1 to describe three nitrous oxide (N2O) production pathways in a laboratory-scale anammox-enriched granular sequencing batch reactor. Heterotrophic denitrification and two processes mediated by ammonia oxidizing bacteria (AOB), that is, (NH4+) oxidation via hydroxylamine (NH2OH) autotrophic denitrification, were considered. systematic calibration validation protocol obtain unique set kinetic parameters...
The investigation of partial denitrification/anammox (PD/anammox) processes was conducted under autotrophic (N–S cycle) and mixotrophic (N–S–C conditions over 180 days. Key findings revealed the remarkable capability SO42--dependent systems to produce NO2− effectively, supporting anaerobic NH4+ oxidation. Additionally, SO42− served as an additional electron acceptor in sulfate reduction ammonium oxidation (SRAO). Increasing influent concentrations notably improved ammonia utilization rates...
The efficiency of deammonification depends on the cooperation ammonium oxidizing bacteria and archaea (AOB/AOA), anaerobic (AnAOB) effective suppression nitrite (NOB) that compete with AnAOB for (NO2-N). One NOB strategies is intermittent aeration. However, it important to have a good understanding optimum dissolved oxygen (DO) value in aeration period optimize non-aeration time used during reaction phase. This study comprised investigation effect different DO set points (0.4, 0.7, 1.0 1.5...
Untreated wastewater released into rivers can result in water pollution, the spread of waterborne diseases, harm to ecosystems, contamination soil and groundwater, as well air pollution respiratory problems for nearby humans animals due release greenhouse gases. The current study aims investigate recent input anthropogenic loads using linear alkylbenzene (LAB), which is one molecular chemical markers with application sophisticated model statistical analyses. In order determine compositions...
Abstract Several studies have been directed to find scalable, swift, accurate, and cost‐effective strategies for detecting, monitoring, treating coronavirus disease 2019 (COVID‐19). Indeed, the lack of a fast practical method detecting infected regions makes decision‐making challenging combat critical pandemic‐struck situations. The probable ‘wrong’, or rather inadequate, decisions not only boomerang effect on economy but also can lead an increase in number individuals, degree...
A one-stage partial nitritation/anammox (PN/A) process with intermittent aeration is possible under sidestream conditions, but implementation in a mainstream challenge due to increased Carbon/Nitrogen (C/N) ratios domestic wastewater. This study investigated the effect of C/N on efficiency and narrowing non-aeration time improvement at high chemical oxygen demand (COD) load. An increase TN removal was achieved both series gradual change ratio from 1 3, 65.1% 83.4% 63.5% 78% 1st 2nd series,...
In this study, by-products from alcohol production were examined in terms of their potential application as external carbon sources for enhancing denitrification biological nutrient removal systems. Three types batch tests used to compare the effects distillery by-products, such fusel oil, syrup and reject water, on non-acclimated activated sludge. Much higher nitrate utilization rates (NURs) observed latter two sources. conventional NUR measurements (one-phase experiments), NURs with water...
The short-term effects of temperature on deammonification sludge were evaluated in a laboratory-scale sequencing batch reactor (SBR). Mathematical modeling was used for further evaluations different intermittent aeration strategies achieving high and stable performance at decreasing temperatures. As the biomass cultivated temperatures (e.g., 30 °C), higher dependency (the adjusted Arrhenius coefficient θ 11–17 °C = 1.71 vs. 17–30 1.12) specific anammox growth rates found lower (11–17 °C)...
Arsenic (As) is a prominent carcinogen component produced via both geogenic and anthropogenic processes, posing serious risks to human health. This study aimed investigate the potential of hydrochar prepared from red macroalgae for removing As synthetic wastewater. The was through 5 h hydrothermal carbonization (HTC) treatment at 200 °C, then, chemically activated with ferric chloride hexahydrate (FeCl3·6H2O). SEM analysis revealed permeable structure hydrochar, while FTIR detected...
In this study, the use of linear alkylbenzenes (LABs) was employed to pinpoint sources human activity that cause detrimental impacts on coastal environment and river ecosystems. LABs were detected using GC–MS in sediment samples assembled from Kim River (KKR) Port Dickson coast (PDC). To assess significance variations distribution concentrations across sampling sites, study utilized several statistical techniques such as post hoc tests, LSD techniques, analysis variance (ANOVA), Pearson...
