“…In order to find a solution to this problem, the application of dynamic-flow set ups (such as continuous stirring tank reactors (CSTRs)) can be considered as a good alternative. In fact, only few studies have focused on this approach regarding phosphorus removal from aqueous solutions by using powdered marble wastes (Jaouadi et al 2014a) and acid mine drainage (Wei et al 2008).…”

Lead removal from synthetic solutions and real wastewater by Bianco Gioia marble wastes as abundant, renewable and eco-friendly materials was studied under different experimental conditions in a continuous stirring tank reactor. These marble wastes were found to be very efficient in removing lead for several experimental situations. Indeed, for initial aqueous pH values higher than 3.6, a lead removal efficiency of about 100 % was achieved even for high aqueous concentrations (200 mg L -1 ), important feeding flow rates (60 mL min -1 ) and low marble waste dosage (2 g L -1 ). The best removal capacity (175.7 mg g -1 ) was obtained for an initial lead concentration of 200 mg L -1 , a marble waste dose of 5 g L -1 and an aqueous pH of 5. Even using the real wastewater with low aqueous pH (1.1), lead was also completely removed using 20 g L -1 of the tested marble wastes. According to the energy-dispersive spectroscopy and X-ray diffraction analyses, lead removal seems to be controlled by both precipitation as cerussite (PbCO 3 ) and hydrocerussite (Pb 3 (CO 3 ) 2 (OH) 2 ), and adsorption onto the surface particles through cation exchange and complexation. The proposed low-cost material efficiently removes lead present in synthetic solutions and real wastewaters and constitutes an interesting environmental management option.

“…The idea of using iron oxides as filter media or coatings of sorptive filtration media has developed into a popular area of ongoing research (e.g., Heal et al, 2005;Penn et al, 2007;Wei et al, 2008;Fenton et al, 2009;Sibrell et al, 2009). The application of sorptive filtration technologies to address P pollution is an area of study that Boujelben et al (2008) have researched in the industrial town of Sfax, Tunisia.…”

Abstract. This study examines the potential to reuse mine-drainage derived iron oxides as anionic sorbents for sustainable water treatment purposes. Pure iron oxides have been established as effective sorptive media or coatings for water treatment processes; yet, iron oxides from mine drainages remain to be an abundant but unproven source of this raw material. Iron oxides from both passive mine drainage treatment systems as well as environmental discharges of mine water and their associated iron deposits were examined. Based on prior physical characterization, three samples were selected (according to their specific surface area) to evaluate their anionic sorptive capacities pertaining to naturally occurring concentrations of orthophosphate (1.13 ± 0.03 mg/L) in surface waters, and arsenate (117.79 ± 4.08 µg As/L ) in drinking waters. The mine drainage derived iron oxides' performances were compared against a commercial grade iron oxide product, Bayoxide E33 P at static pH values of 6.00, 7.00, 8.00, and 9.00 ± 0.10 standard pH units via laboratory scale sorption batch experiments. As a result of these experiments it was observed that the mine drainage derived iron oxides were more effective at contaminant removal than the commercial product. Promising contaminant removal efficiencies of up to 95% (arsenate) and 99% (orthophosphate) were documented at specific pH values for the mine drainage derived iron oxides, while adhering to virtually all US EPA primary and secondary drinking water standards; thus suggesting that it may be feasible to beneficially reuse mine drainage derived iron oxide in water treatment technologies.

“…In natural and constructed wetlands recently studied bacteria removal by algae-based systems have been studied (Nascimento, 1987;Gabrhelov et al, 1991;Mara et al, 1992;Von Sperling, 2005). Although, there are large number of wastewater treatment techniques and facilities such as adsorption methods, chemical techniques, precipitation, constructed wetlands and other processes are present but the most suitable is biological method because of its least expensiveness for third world countries particularly (Wei, 2008). In areas where there is land, algae based wastewater treatment is a better choice (Zhang and Farahbakhsh, 2007).…”

Present study aim to investigate application of microalgae for improvement of physiochemical parameters of waste water and improvement of treatment process through reducing the pollutant concentrations including coliform bacteria through their ability to uptake nutrients. Aquatic cultures were conducted in container with dimensions of 1.5×3sq ft. and wastewater samples 5 Litre samples were collected in plastic cans from Sukhnar drain and algal samples were collected from Bhaini Sigyain Village near Ravi Siphon, Lahore. The one experimental treatment lasted for 10 days to make 50% 5 liter water added concentration and 200g of inocula of algae were grown in wastewater container for experiments to optimize at room temperature as local outdoor cultures conditions for wastewater treatment. Total experiment repeated thrice and completed in 30 days. Results show that treatments improved the physiochemical parameter after week. Turbidity (NTU), total suspended solids (mg/L), total dissolved solids (mg/L), nitrate (mg/L), phosphate (mg/L) decrease (P < 0.05) after treatment. However, pH not significantly decreases (P≥ 0.05) pre-treatment values 6.56±0.05 (mg/L) and post-treatment 6.53± 0.057(mg/L). Maximum total coliform disinfection (P < 0.05) was indicated with 200 g of algae was pre-treatment 1602± 6.8 (MPN) and post treatment 1447±39.5 (MPN) observed.
