This study investigates the effect of reactor design parameters on cadmium removal from industrial wastewater discharged by Tunisian Chemical Group (TCG) to improve as much possible efficiency and cost electrocoagulation (EC) process. Based an examination one one, best was achieved for inter-electrode distance (die) 0.5 cm, monopolar connection mode, stirring speed 300 rev min−1, surface-area-to-volume ratio (S/V) 13.6 m−1, initial temperature 50 °C. These operating conditions are allowed...
Abstract Fluoride forms a common aqueous effluent in many chemical industries. Excess of fluoride the can cause health hazard. So, containing needs treatment to reduce its concentration disposable value before discharging into public sewage. Removal ion from model water solutions was investigated using polyamide thin film composite reverse osmosis and nanofiltration membranes. The effects feed pressure, concentration, ionic strength, nature cation associated fluoride, pH on retention ions...
Nanofiltration and reverse osmosis are investigated as a possible alternative to the conventional methods of Cr(VI) removal from model water industrial effluent. The influences feed concentration, recovery, pH, coexisting anions were studied. results have shown that retention rates hexavalent chromium can reach 99.7% using nanofiltration membrane (NF-HL) vary 85 99.9% (RO-SG) depending upon composition solution operating conditions. This work was also extended investigate separation car...
Industrial effluents loaded with cadmium have contributed to the pollution of environment and health troubles for humans. Therefore, these need treatment reduce concentration before releasing them public sewage. The purpose research is study major role reverse osmosis (RO) nanofiltration (NF) processes, which can contribute removal ions from model water wastewater battery industry. For this reason, two RO membranes been used. effects feed pressure, concentration, ionic strength, nature anion...
Abstract In this study, a response surface methodology (RSM) approach using central composite design (CCD) was investigated to develop mathematical model and optimize the effects of pH, adsorbent amount temperature related hexavalent chromium removal by biosorption on peanut shells (PSh). The highest percentage 30.28% found predicted under optimum conditions (pH 2.11, 0.73 g PSh 37.2 °C) for 100 mg/L initial Cr(VI) concentration, which very near experimental value (29.92%). characterized...
Constructed wetlands system (CWs) have been proposed as an economical, efficient and sustainable wastewater treatment technology. The aim of this paper was to provide the first published data on efficiency CWs for dairy in Tunisia. In most CWs, good organic, total suspended solids (TSS) nutrient removal measured. order evaluate process, hybrid small-scale wetland designed containing three horizontal subsurface flow (HSSF) one free water surface (FWS). A mixture Reeds (Phragmites australis),...
Phenols are considered as organic pollutants that discharged into the environment causing contamination of drinking water, aquatic life, and plants, therefore, affecting human. Various treatment technologies for removal from water have been used such as, liquid–liquid extraction, ionic exchange with resins, membrane processes. In this study, adsorption phenol aqueous solutions were studied using a polyamide thin film composite reverse osmosis denoted AG 2514 TF Osmonics company. The...
Abstract The occurrence of boron in water and its inefficient removal are the key issue desalination treatment. Adsorption by fixed-bed column is usually used to remove mineral organic contaminants from aqueous phase. adsorption onto activated carbon, prepared palm bark, studied. Batch experiments developed determine equilibrium time best isotherm model. kinetic data can be described second-order equation. Among models, Langmuir Sips models give better fit data. calculated thermodynamic...
Abstract The aim of this work is to study the removal fluoride from brackish polluted water using electrodialysis. influence several parameters such as flow rate, initial feed concentration, co‐existing ions, and pH on process efficiency were studied. This evaluated by demineralization power consumption. defluoridation showed be independent solution. Although remained studied plays a significant role mainly specific contaminated real sample was investigated so improve process. concentration...
Lead is a priority substance in the framework of European water policy (Water Framework Directive 2000/60/EC and Water Environmental Quality Standards 2008/105/EC), since it presents significant risk to biota humans, given its persistence, toxicity bioaccumulation characteristics. This study devoted focus on lead removal by means electro coagulation (EC). The performance EC process with aluminium electrodes for laboratory electrochemical cell was studied. effects various parameters such as...
