Coloured wastewaters are a consequence of batch processes in both dye-manufacturing and dye-consuming industries. Dyes are widely used in a number of industries, such as textile and leather dyeing, food, cosmetics, paper printing, gasoline, with the textile in‐ dustry as the largest consumer. Dyeing as a fundamental operation during textile fibre processing causes the production of more or less...

One of the most serious environmental problems is the existence of hazardous and toxic pollutants in industrial wastewaters. The major hindrance is the simultaneous existence of many/different types of pollutants as (i) dyes; (ii) heavy metals; (iii) phenols; (iv) pesticides and (v) pharmaceuticals. Adsorption is considered to be one of the most promising techniques for wastewater treatment ove...

Olive mill wastewaters (OMW) are a by-product from olive oil manufacture that cause environmental pollution. These wastes have been used as substrate for the production of the extracellular polysaccharide xanthan by Xanthomonas campestris NRRL 31459-S4L41. Growth and xanthan production on dilute OMW as a sole source of nutrients were obtained at OMW concentrations below 60%, yielding a maxima1 ...

A sentinel network, Obépine , has been designed to monitor SARS-CoV-2 viral load in wastewaters arriving at wastewater treatment plants (WWTPs) France as an indirect macro-epidemiological parameter. The sources of uncertainty such a monitoring system are numerous, and the concentration measurements it provides left-censored contain outliers, which biases results usual smoothing methods. Hence, ...

mfi zeolite membranes were prepared on porous α-alumina substrates, using secondary growth of nano-seeded layers. the resulting membranes were characterized by means of scanning electron microscopy (sem), x-ray diffractometry (xrd), and pervaporation performance tests for separation of benzene, toluene and xylene (btx) mixture from contaminated water. the morphology, thickness, homogeneity, cry...
