Optimization of process conditions for the removal Remazol Black B was investigated using response surface methodology (Box–Behnken design). The biodecolorization dye studied biochar produced from waste biomass Caulerpa scalpelliformis (marine seaweeds). reactions were optimized by varying sorbent dosage, solution pH, temperature, and initial concentration. results indicated that efficiency 80....

In this study, the construction and test of tapered plastic optical fiber (POF) sensors, based on an intensity modulation approach are described. Tapered fiber sensors with different diameters of 0.65 mm, 0.45 mm, and 0.35 mm, were used to measure various concentrations of Remazol black B (RBB) dye aqueous solutions at room temperature. The concentrations of the RBB solutions were varied from 0...

Pycnoporus sanguineus is a white-rot basidiomycete that produces laccase as the only oxidoreductase; enzyme synthesis depends on cultivation variables, and fungal species and strain. Laccases have wide substrate specificity, oxidize a broad range of compounds, and show potential for use in dye decolorization. We evaluated laccase production in a recently isolated strain of P. sanguineus cultiva...

Nowadays, water pollution has become a matter of great concern in our society. Most of the water pollutions are related to the industrial effluents. Textile industry is the one of the most important industry in all over world and this industry uses large volumes of water in wet processing operations and thereby, generates substantial quantities of wastewater containing large amounts of dissolve...

The measurement and prediction of dye concentration is important in the design, planning and management of wastewater treatment. Soft computing techniques can be used as a support tool for analyzing data and making prediction. In this study, Central Composite Design (CCD) and adaptive neuro-fuzzy inference system (ANFIS) are employed to identify and predict the output intensity ratio of light t...
