Compounds with primary amino groups react with o-phthalaldehyde in solution to yield highly fluorescent products. This reaction is now in wide use for detecting amino acids and amines in liquid-chromatography effluents. We report here a method for using o-phthalaldehyde to detect primary amines in the effluent of a gas-liquid-chromatographic column. The effluent gas, nominally 20 mL/min, is del...

The present study deals with the assessment of toxicity of distillery effluent on soil microorganisms and its quality improvement through bioremediation using Pseudomonas spp. Under lab scale experiment, different dilutions of distillery effluent i.e. 25%, 50%, 75% were used to examine effects on physico-chemical parameters of effluent and on soil microflora e.g. algae, bacteria, fungi and acti...

The purpose of this article is to investigate the applications of hydroponic wastewater management systems (HWMS) as wastewater treatment facilities for the Dead Sea vicinity. In addition, it aims at managing the wastewater through generating commercially valuable plants using a proposed HWMS. A commercial hydroponic system was adapted for studying the potential heavy metals removal from primar...

Sequencing batch membrane bioreactors can be a good option in up-grading small municipal plant and for industrial applications, maintaining some of the advantages of both original technologies (effluent quality improvement, flexibility and simplicity of realization, operation and control). In this study, the effects of volumetric exchange ratio (VER) and aeration/filtration strategy have been e...

The occurrence, fate and environmental impact of 30 pharmaceuticals including sulfonamides, fluoroquinolones, tetracyclines, macrolides, dihydrofolate reductase inhibitors, β-blockers, antiepileptics, lipid regulators, and stimulants were studied in two municipal wastewater treatment plants (WWTPs) located in Wuxi City, East China. A total of 23 pharmaceuticals were detected in wastewater sampl...

Abstract Antimicrobial resistome in wastewater treatment plants was investigated via shotgun metagenomic analysis over a variety of geographical locations, seasons, and biological configurations. The results revealed that the transition antimicrobial occurred at two locations during treatment, which resulted distinctive influent wastewater, activated sludge, treated effluent. characterized by h...

In this work, Direct Contact Membrane Distillation (DCMD) was applied for the treatment of municipal wastewater collected from primary clarifier a plant (MWWTP). The water flux at 60℃ and 20℃ feed permeate side, respectively 51 kg/m2h in treating effluent. Meanwhile, electrical conductivity distillate good range 1.5 – 1.8 S/cm. Most representative parameters reuse (SS, nitrate, nitrite, phospha...
