The complex and variable nature of effluent necessitates a thorough analysis of its physical and chemical characteristics. This analysis is the foundation for designing the most cost-effective and efficient treatment process for your needs. ...
Sodium bisulfite is an oxygen-demanding chemical, making it preferable as a means to minimize any excess amount in the plant effluent by performing an on-line analysis to continuously monitor the residual concentration. ...
In this work, hydrogen thermal desorption from AB, which has been incorporated into various mesoporous carriers, has been investigated by means of operando Raman – Mass Spectrometry methodology which consists in using a combination of real-time Raman spectroscopy measurements and simultaneous on-line analysis of the effluents by a Hiden HPR-20 quadrupole ...
Abstract :The toxicity of a sediment pore water and an effluent was characterized using Toxicity Identification Evaluation (TIE) procedures. ...
The average value achieved for chemical oxygen demand (COD) removal was 87% and for methane yield was 0.12 L CH4/gCODremoved. Based on mass balance analysis, it was found that about 30% of total influent COD was used for methane conversion, 15% of COD for sulfate reduction, 10% for biomass growth and 10–20% of COD remained in the effluent. ...
The study was executed at Kalurghat industrial area to determine the efficiency of effluent treatment plants by testing different physicochemical parameters. Results revealed that only 3 out of 9 industries treated their effluents efficiently and discharged following the standards of Department of Environment. The remaining industries viz. Alfa Textile treated their effluent but the values of ...
The results showed that Fe(II)-PS system was effective in COD removal from the secondary effluent. PS dosage was the most dominant factor with positive influence on COD removal, followed by initial pH value. The optimum conditions with COD removal of 54.4% were obtained at PS/COD of 2.2, initial pH of 6.47 and Fe(II)/PS of 1.89. UV-visible spectrum analysis ...
The principle of step-wise assessment of bacterial growth-controlling factors was demonstrated on bottled water, shown to be primarily carbon limited at 133 (±18) × 103 cells mL−1 and secondarily limited by inorganic nutrients at 5,500 (±1,700) × 103 cells mL−1. Analysis of the effluent of a Dutch full-scale drinking water treatment plant showed (1) bacterial ...
In order to obtain a benchmark regarding the degree of acid mine drainage (AMD) pollution in the aquatic environment, the relationship between the areas occupied by the sulfide mines and the characteristics of the respective effluents after rainfall was analysed. The methodology developed, which includes the design of a sampling network, analytical treatment and cluster ...
Wastewater treatment plant (WWTP) effluents are known contributors of chemical mixtures into the environment. ...
For example, site assessments are routinely combined with laboratory analysis (e.g. waste water, incoming water, sludge sampling). Thus, voluntary initiatives are a strong driver for supply chain improvement, which coincide with higher regulatory and NGO pressures. ...

Cytotoxic drugs (tamoxifen and cyclophosphamide) and x‐ray contrast media (iopamidol and diatrizoic acid) were infrequently detected in hospital effluents. Analysis for antibiotics indicated that azithromycin, clarithromycin, ciprofloxacin, erythromycin, ofloxacin and sulfamethoxazole were consistently detected in hospital wastewaters as was triclosan ...
This paper used a variety of methods to analyse the effluent, including chemical method, spectrophotometry and X–ray diffractometer. The effluent was detected to contain a large amount of chloride, sulphate and nitrate ions, and the mass fraction of chloride ion was as high as 3.2%. ...
Analysis of the WWTP effluent and river water detected estrone and 17β‐estradiol at concentrations up to approximately 25 ng L−1 throughout the experiment. Anti‐estrogenicity of effluent samples was detected in vitro using yeast‐based bioassays (YES) throughout the experiment, but estrogenicity was limited to the first week of the experiment. ...
Blends were subjected to chemo-physical and gaseous emission analysis using different ASTM methods and GC mass spectrophotometer for the trapping and subsequent analysis of the effluents. ...
The Belfast site conducts clean water bacteriological analysis and all clean water chemistry. Londonderry is responsible for some clean water bacteriological, cryptosporidia, wastewater and trade effluent analysis. ...
Knowledge of the amount of bank filtrate in raw water is crucial for drinking water suppliers using water wells in close proximity to rivers, in particular if those rivers are strongly affected by anthropogenic activities, e.g. receiving effluents from waste water treatment plants. Analysis of organic micropollutants as tracer compounds is costly and ...
The whole effluent toxicity (WET) program in the United States, Canada, and other countries typically requires multi concentration testing of effluents. ...
Ongoing long-term studies of subsurface intakes in Long Beach and Dana Point, California are expected to provide comprehensive data that would allow completing a scientifically-based analysis of the viability and performance benefits of alternative subsurface intakes. ...
Performance of Constructed Wetland planted with vetiver grasses for the treatment of leachate was investigated in controlled experiments involving horizontal subsurface flow constructed wetland (HSSFCW). The HSSFCW experimental unit had two cells, one planted with vetiver grasses and another bare. Both units were packed with limestone gravel as substrate and were operated with equal hydraulic ...
