the present study was carried out to investigate the potential of single-walled carbon nanotube (swcnts) and carboxylate group functionalized single-walled carbon nanotube (swcnt-cooh) as alternative adsorbents for the removal of basic red 46 (br 46) from contaminated water by using batch adsorption studies. effects of some key operating parameters such as ph, ionic strength and contact time on...

“Everything is everywhere, but the environment selects the best duo’’; natural selection holds the key to the relationship between the micro-algal communities in Lake Mälaren and the activated sludge organisms in the municipal wastewater of Västerås. Interest in microalgae-based activated sludge wastewater treatment has been increasing in recent decades as a way to meet the demand for sustainab...

The beverage industry has been a heavy producer of organic pollution. The major contaminants found in waste are biodegradable organic compounds, volatile organic compounds, toxic metals, and recalcitrant xenobiotics, suspend solids, nutrients (Nitrogen and Phosphor) Microbial pathogens and parasites. Activated sludge flocs contain a wide range of microorganisms such as bacteria, Fungi, yeast, v...

carbon activated powdered was prepared from activated carbon derived from olive stone. then byusing the surface methodology, many parameters such as ph, furnace temperature (t), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. in addition, the adsorption of congo red onto the activated olive stone carbonactive was...

High-surface-area mesoporous MgO-templated nanocarbons made with reinforcing fibres from scrap tyres and a bituminous waste as carbon precursor were employed for the simultaneous adsorption of Cd and reactive Cibacron Brilliant Yellow 3G-P dye. A commercial activated carbon (AC) Darco KB-WJ was also used for comparison purposes. The effect of the pH of the solution was studied to establish whet...

This work investigates the competitive adsorption under dynamic and equilibrium conditions of ibuprofen (IBU) and amoxicillin (AMX), two widely consumed pharmaceuticals, on nanoporous carbons of different characteristics. Batch adsorption experiments of pure components in water and their binary mixtures were carried out to measure both adsorption equilibrium and kinetics, and dynamic tests were...

Background: Investigating the performance of naturally operated treatment plants may be due to the fact that they cannot be operated as desired, or that they should be modified to achieve good performance e.g. for nutrients removal. The advantage of kinetic coefficient determination is that the model can be adjusted to fit data and then used for analyzing alternatives to improve the process. Th...
