“…The high availability of active sites on the surface of TAW may explain the rapid increase in piroxicam removal in the first phase of treatment. These phenomena can be explained by exhausting all active sites which exist on the surface of the studied material (TAW) [32,33]. We may also deduce from the curve that the amount adsorbed quantity of TAW is 0.13 mg/g in 45 minutes.…”

The presence of pharmaceuticals in the environment has increased. These pollutants are toxic and non-biodegradable. Piroxicam (PRX) is a non-steroidal anti-inflammatory drug that ends up in wastewater via pharmaceutical industry activities and human being consumption. This work aimed to study the pharmaceutical pollutant removal from wastewater using agricultural by-products as low-cost adsorbent material. Different parameters were studied, such as time, initial adsorbate concentrations, and temperature. The study of the initial concentration-effect shows that the greatest amount of adsorbed is observed in low concentrations. The temperature has shown a negative effect in this study. The kinetics show that after 45min, the equilibrium is obtained; that means the exhaustion of all active sites. The representative model of this adsorption is the Langmuir isotherm according to the regression coefficient, which is equal to 0.99. The natural abundance of this material and the low cost of investment could offer a good alternative to other more expensive adsorbents such as activated carbon.

“…For example, at 20 mg/L qe, cal (BR/ALP) was equal to 4.29 mg/g and qe, exp(BR/ALP) equal to 4.07 mg/g, whereas at 100 mg/L qe, cal (BR/ALP) was equal to 14.06 mg/g and qe, exp(BR/AL)was equal to 14.84 mg/g, thus confirming that the pseudo-second-order model is the most applicable in the case of discoloration of BR in the studied system. The results suggested that the dye uptake process is attributed to chemical adsorption, even though physical adsorption and chemical adsorption may be difficult to distinguish [45].…”

Currently, the dye industry is increasing its production as a consequence of the growing need for their products in different manufacturing sectors, such as textiles, plastics, food, paper, etc... Thereafter, these industries generate very large volumes of effluents contaminated by these dyes, which require proper removal treatment before final discharge of the effluents into the environment. In this study, artichoke leaves were used as an economical and eco-friendly bio-adsorbent for Bengal Rose (BR) dye removal. Bio-adsorbent obtained from artichoke leaves was ground to powder size. The resulting powder was characterized by different methods, such as Brunauer-Emmett-Teller (BET) surface area analysis, scanning electron microscopy(SEM), X-ray Diffraction (XRD), Fourier transfer infrared (FTIR), pH at point of zero charge (pHpzc), equilibrium pH, iodine number, methylene blue number, phenol number, density, Energy dispersive X-ray spectroscopy (EDX) and Thermo-gravimetric analysis (TGA). Thereafter, the bio-adsorbent was used to study its capability for removing BR dye by testing contact time, initial concentration of dye and temperature. The results show that the saturation of bio-sorbent was reached after 40 min and the removal rate of BR dye by artichoke leaves powder (ALP) was 4.07 mg/g, which corresponds to a removal efficiency of 80.1%. A design of experiences (DOE) based on a two-level full factorial design (23) was used to study the effects of different parameters, such as pH, temperature and bio-adsorbent dosage on BR dye removal efficiency. The obtained results show that the highest removal efficiency was 86.5% for the optimized values of pH (4), temperature (80 °C) and bio-adsorbent dosage (8 g/L). Furthermore, a satisfying accordance between experimental and predicted data was observed. The kinetic and isotherm studies show that the pseudo-second order model simulated adequately the obtained data and it was found that Langmuir and Temkin isotherm models are liable and suitable for evaluating the adsorption process performance. Free energy change of adsorption (ΔG°), enthalpy change (ΔH°) and entropy change (ΔS°) were furthermore calculated to predict the nature of the adsorption process.

“…The Danone salt water plant is equipped with a reverse osmosis treatment plant. The reverse osmosis process is a membrane filtration technique generally used in the desalination of brackish water and sea water.The main objective of this technology is the removal of salts and organic substances substances present in water [15][16][17][18]. Wastewater treatment is the reduction of pollution that is present in the water.…”

The objective of the present work is to monitor and control the physicochemical quality of the osmosis water that feeds the dairy industry in our case the Danone plant (DP) "Factory of Salé", for good production and use without no risk. The drilling water treatment and purification technique applied in the Danone plant is reverse osmosis. The approach of this membrane technique at a pressure gradient, allows obtaining good quality water for use in the various activities of the plant. During a 30-day period, we tested the pH, conductivity, alkalinity, hydrometric title, total alkalinity, chlorides content and chlorine content on water drawn from the borehole, the 1μ filter output, the treated output A and the treated water. The results of the experimental analyzes generally comply with the standards imposed within the plant, with the exception of a few days where cleaning of the membranes is necessary.
