Abstract Global warming is affecting animal populations worldwide, through chronic temperature increases and an increase in the frequency of extreme heatwave events. Reservoirs are essential for water security. All watersheds with reservoirs impacted by their construction. These artificial ecosystems controlled humans change considerably natural terrestrial aquatic ecosystem systems biodiversity. The rapid population growth, urbanization, industrialization accompanied river discharges, which...

Climate change has several impacts on rainfall patterns, increasing surface runoff, leading to sewer flooding, and receiving water contamination. This study analyzed the effects of climate flooding Al-Shuhada Quarter system in Samawah City, Iraq, using Storm Water Management Model (SWMM). The sanitary system's performance was evaluated before after leaking stormwater at different return periods two, five, ten, twenty-five years. SWMM model manually calibrated by changing influential...

Odors due to the emission of hydrogen sulfide (H2S) have been a concern in sewage treatment plants over last decades. H2S fate and emissions from extended aeration activated sludge (EAAS) system Muharram Aisha-sewage plant (MA-STP) were studied using TOXCHEM model. Sensitivity analysis at different flowrate, loading rate, wastewater pH, temperature wind speed studied. The predicted data validated against actual results, where all within limits, statistical evaluation normalized mean square...

Abstract Flooding of stormwater drainage systems represents a major problem in developing urban areas that could be influenced by land-use and climate change. problems can assessed using simulation models such as the management model (SWMM). In this study, generation intensity duration frequency curves (IDF) integrates change effect was conducted for Al-Najaf Governorate Iraq first time. addition, effects on sewer system Al-Ameer District simulated SWMM. The results indicated increasing...

In this study, hexadecylamine (HDA) impregnated chitosan-powder activated carbon (Ct-PAC) composite beads were successfully prepared and applied to adsorption of the anionic dye reactive black 5 (RB5) in aqueous solution. The Ct-PAC-HDA synthesized with 0.2 g powdered (PAC) 0.04 HDA showed highest removal efficiency. characterized using Fourier-transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM). Various parameters, i.e., adsorbent dosage, pH, contact time, which affect...

Pigment production plants are among the most polluting industries due to their high-water consumption and complex releases. The current work investigates removal efficiency of sodium chloride (NaCl), acetate (C2H3NaO2), acetic acid (CH3COOH), also permeate flux a small-batch OPM-K membrane using reverse osmosis (RO) pilot plant at various concentrations pressures. At 0.034 M applied pressure 30 bar, results showed that maximum flow were 93.4% 8.3 × 10−6 m/s, respectively. When feed...

Abstract This paper describes the application of storm water management model (SWMM) for predicting sewage quality in sanitary sewer system study area resulting from leaking stormwater surface runoff to during rainfall events at different return periods. The concentrations major pollutants were assessed intensities. Then, a solution mitigate problem was proposed using low impact development (LID) technology. results sensitivity analysis indicated that maximum build-up possible most sensitive...

Abstract The novel process consisted of two steps was established by combining all sidestreams lines (supernatant gravity thickener, underflow mechanical and centrate), treating them together away from the mainstream treatment plant, returning treated effluents to plant outfall instead head. novelty combined degradation, nitrification, dilution processes. To treat sidestreams, a pilot extended nutrient moving bed biofilm reactor developed. effects sidestream elimination on full-scale...

Excess sludge production is one of the limitations biological activated process. Therefore, study’s objective to upgrade MBBR process an integrated fixed film-activated (IFAS) reduce excess production. Two scenarios were followed in this study eliminate process: first, modifying moving bed biofilm reactor (MBBR) system by increasing solid retention time (SRT) from 5 15 days; and second, upgrading fixed-film applying return (RAS) 50, 100 150% with operating hydraulic (HRT) 6, 12, 14 20 h. The...

Abstract The quality of the surface water along Kunhar River in Mansehra district, KPK Pakistan was assessed for ten samples stations. A variety parameters indicating including physicochemical parameters, nutrients, heavy metals, and antibiotic residues were measured both rainy dry seasons, two main tropical seasons Mansehra, using standard methods. River, one local drinking sources, studied to assess metal content, health risk assessment, its suitability human consumption. Health assessment...
