This paper explores the use of nanofiltration (NF) and Reverse Osmosis (RO) to remove pharmaceutical Fluoxetine (FLX) from water. substance can be found in rivers lakes requires studies involving application efficient technologies for its removal or mitigation. The study evaluated NF RO membranes as an alternative removed fluoxetine within range between 50 60%, demonstrated higher efficiency re...

The evaluation of a membrane bioreactor (MBR) for pretreatment of reverse osmosis (RO) in order to reuse and reclamation of industrial town wastewater treatment plant was investigated in this study. Performance of MBR effluent through water quality in term of parameters such as chemical oxygen demand (COD), total suspended solids (TSS), total nitrogen (TN) and total coliform (TC) were measured....

An osmotic membrane bioreactor-reverse osmosis (OMBR-RO) hybrid system integrated with periodic microfiltration (MF) extraction was evaluated for simultaneous phosphorus and clean water recovery from raw sewage. In this hybrid system, the forward osmosis membrane effectively retained inorganic salts and phosphate in the bioreactor, while the MF membrane periodically bled them out for phosphorus...

Wastewater from the wood and pulp industry is of environmental concern. It contains high concentrations of organic and inorganic matter. In this work a combined method of coagulation, adsorption and nanofiltration/reverse osmosis (NF/RO) was investigated in the purification of biologically treated wastewater from wood processing. Coagulation with 0.8 g dm(-3) AlCl3 x 6H2O and adsorption on 2.5 ...

This study aims at studying the environmental effects of desalination byproducts and the cost analysis of desalination systems. Focus was made on the two widespread techniques of seawater desalination; the Multistage Flash (MSF) System and Reverse Osmosis (RO) system. These two technologies of thermal and membrane desalination have a substantial history and their industry is well established. M...

This study aims at applying and verifying the MFI-UF method to predict particulate fouling in RO plants. Two full-scale plants treating surface water, with average capacity of 800–2000 m3/h, were studied. Firstly, feed concentrate was measured using 5–100 kDa membranes same flux applied (20–26 L/m2.h). Subsequently, particle disposition factor (?) calculated simulate deposition cross-flow filtr...

Pretreatment of reverse osmosis (RO) feed water high mineral scaling propensity was evaluated with respect to downstream RO membrane scaling, for two different pretreatment configurations. The schemes included (i) media sand filtration, followed by a hydrocyclone (HC) and (ii) hydrocyclone, microfilter, UF module, where both configurations mesh screens added protection. first configuration redu...

Growing demand for water desalination promoted the vigorous development of reverse osmosis (RO) membrane. How to effectively remove boron from seawater is key problem be solved by RO It important select suitable membrane materials experimental design before complicated and expensive attempts. In this paper, we demonstrate that pore chemistry plays a role in removal capability membranes via none...

The different methodologies of leachate treatment are widely debated in the literature, promoting a great discussion among scientific and academic community on most efficient propitious methods. Membrane processes, especially Reverse Osmosis (RO), stand out as best solution. RO has pollutant removal rates higher than 99%, with operational cost complexity competitive other technologies. Its main...
