Performance of chlorination process during nanofiltration of sulfonamide antibiotic
The effectiveness of combined nanofiltration and disinfection processes was studied by comparing the pre-disinfection and post-disinfection when in combination with nanofiltration. Four types of sulfonamide (sulfanilamide, sulfadiazine, sulfamethoxazole, and sulfadimethoxine) were chosen as substrates, with sodium hypochlorite as a disinfectant. A laboratory-scale nanofiltration system was ...

Nanofiltration Systems Sulfate Removal
Membrane filtration principle Membrane filtration technology is based on a selective filtration through a pressure-driven membrane for sulfate water treatment. The membrane has charged groups that selectively reject multivalent anions such as SO42-. The membrane does not separate monovalent ionic species such as Cl- or CLO3- from the feed solution. To maximize the membrane area within a compact ...

Removal of hexavalent chromium from brackish groundwater by nanofiltration: a case study in Iran
The hexavalent chromium Cr (VI) and sulfate concentrations in some groundwater sources used for drinking water in Birjand, the capital of Southern Khorasan Province, Iran, are greater than the established maximum concentration levels (MCLs). In this work, a nanofiltration system was examined as a promising method for the simultaneous removal of Cr (VI) and sulfate from groundwater. The effects of ...

Industrial water reuse opportunities and high temperature compatible membranes
Process condensates represent a real value to the industry as it usually contains several items of potential savings, including but not limited to heat energy and water. In most cases the condensate has become contaminated with unwanted particles or with product carryover making it unfit for direct reuse in the process or as boiler makeup water. Conventional methods use heat exchangers for ...

A New Fast Acting Low PH Cleaner Paves the Way for a New Cleaning Philosophy for Integrated Membrane Systems
Abstract For many years ultrafiltration/microfiltration (UF/MF) has been replacing multi-media filtration as a seawater reverse osmosis (RO) or nanofiltration (NF) pre-treatment system. Initially the systems were treated as individual unit operations and optimized as such. However, the similarity in the flux maintenance requirements of the particle removal membranes and the desalination ...

Nanofiltration performance of lead solutions: effects of solution pH and ionic strength
Nanofiltration performance (i.e. rejection and flux decline) of lead solutions was investigated using a dead-end test cell at room temperature. An aromatic polyamide NF-90 membrane was chosen to determine the impacts of solution chemistry. The experimental results revealed that solution flux decline was dependent on solution pH, ionic strength, and type of lead solutions. Solution flux conducted ...
