Bioretention systems modified with water treatment residuals and internal storage zone are effective for removal of N, P, TSS, COD, heavy metals in rainfall runoff.
Nitrite-oxidizing bacteria (NOB) are crucial to nitrification and nitrogen elimination in wastewater treatment. Mass reports exist on the links between NOB other microorganisms, for instance, ammonia-oxidizing (AOB). However, a few studies enrichment characterisation of under high dissolved oxygen (DO) conditions. In this study, was designed be enriched individually DO conditions continuous aeration sequencing batch reactor (SBR), kinetic evaluated. The analysis revealed that average NO2--N...
Climate change has often caused failure in water treatment operations. In this study, we report a real case study at major surface plant Alabama, USA. Following severe winter storm, the effluent turbidity surged to >15.00 Nephelometric Turbidity Units (NTU), far exceeding 0.30 NTU standard. As result, operation had be shut down for three days, causing millions of dollars losses and affecting tens thousands people. Systematic jar tests were carried out with sediment samples from 22 upstream...
Abstract Odor issues occurring in drinking water have been a big challenge to face for suppliers globally, which highly commend develop quick or on-site odor detection tools the management of problems. Olfactory sensors based on odor-binding proteins (OBPs) utilized analyze pollutants food and air samples, while their application typical odor-causing compounds is rarely reported, partly due lack knowledge about binding properties odorants. In this study, affinity mechanism human protein...
is a common genus of nitrite-oxidising bacteria (NOB) found in wastewater treatment plants (WWTPs). To identify the key factors influencing composition NOB communities, research was conducted using both sequencing batch reactor (SBR) and continuous flow under different conditions. High-throughput 16S rRNA gene revealed that
Coxsackie B3 (CoxB3) virus was used as a virological tracer for an assessment of the efficiency pathogen removal by several typical physicochemical treatment and chemical disinfection processes, such coagulation-filtration, ultra-filtration, using chlorine ozone, with regard to pathogenic quality treated domestic wastewater reuse purposes. The CoxB3 seeded sterilized secondary effluent make raw water known level. After applying each or process, residual in finished concentrated, assay...
Thermal hydrolysis processes (THP) play an important role in sewage sludge treatment. In this study, both low-temperature (60°C–90°C) and high-temperature (120°C–170°C) thermal experiments were performed on the initial (at a total solid of 7.03% 6.45% by weight). The results have shown that release organic matter is logarithmic with duration during (LTHP). For (HTHP), linear treated temperature. Good relationships obtained between soluble chemical oxygen demand (rSCOD)...

Glyphosate, a broad-spectrum herbicide, poses potential threat to human health and the ecosystem due its toxicity. In this study, iron-based water treatment residuals (Fe-WTRs) were employed for glyphosate removal. The adsorption kinetics, isotherms, thermodynamics, as well effects of pH, Fe-WTR particle size, temperature, explored. results show that Fe-WTRs are an effective adsorbent adsorption, maximum uptake capacity was recorded 30.25 mg/g. surface positively charged, low-valent iron...
A study was conducted on the distribution of pollutants in treated wastewater and its safety for re-use purposes. Based results a series tertiary treatment experiments, effects three filtration processes, i.e. coagulation-filtration, ozonation-biological activated carbon (O3-BAC) ultrafiltration (UF), two chemical disinfection chlorination ozonation, water were evaluated. It found that concentrations main secondary effluent further filtered follow log-normal and, therefore, probabilistic...
Under high DO at about 1.5-2.5 mg·L-1 and environmental temperatures (15-20 ℃) conditions, the NOB was entirely washed out, partial nitrification (PN) successfully achieved in 180 days. The sludge first enriched for 37 days, kinetic parameters of AOB were determined. substrate affinity coefficient 13.38±1.48 mg·L-1; FA inhibition 3.18±0.60 half-saturation constant 1.22±0.22 0.23±0.03 respectively. It contrary to conventional studies, stronger than that this study. Therefore, it is not...
Nanoscale zero-valent iron (nZVI)-multiwalled carbon nanotube (MWCNT) was first applied to remove polychlorinated biphenyls (PCBs) from water.The characterization result scanning electron microscopy, transmission and X-ray powder diffraction showed that the nZVI immobilized successfully on surface or into network of MWCNTs.The effects different reaction conditions like temperature, initial pH values, MWCNT-nZVI dosage, PCBs concentrations for removal were evaluated.Comparing pure MWCNT,...
Wastewater Treatment Plants (WWTPs) have to deal with the issue of energy saving and/or CO2 reduction. Aeration, sludge return, chemical dosing, reduction, digestion, etc. could indeed some function on this issue. On other hand, controlled processes COD and nutrient conversions also be benefit With paper, relationship between consumption emission is firstly analysed. Applicable technologies recovery via are then evaluated. Finally, denitrifying dephosphatation reduction demonstrated by...
