Composition and variability of biofouling organisms in seawater reverse osmosis desalination plants.
Seawater reverse osmosis (SWRO) membrane biofouling remains a common challenge in the desalination industry, but the marine bacterial community that causes membrane fouling is poorly understood. Microbial communities at different stages of treatment processes (intake, cartridge filtration, and SWRO) of a desalination pilot plant were examined by both culture-based and culture-independent approa...
متن کاملNovel Membrane Materials for Reverse Osmosis Desalination
The use of solvents in desalination processes limits the use of certain materials in the construction of the reverse osmosis membranes. Therefore now the research effort has focused on improving new materials. In particular, nanostructured materials will probably form the basis for new reverse osmosis membrane materials. This study makes a review of the new materials used for the construction o...
متن کاملPeriodic Control of a Reverse Osmosis Water Desalination Unit
Enhancement of the performance of a reverse osmosis (RO) unit through periodic control is studied. The periodic control manipulates the feed pressure and flow rate of the RO unit. To ensure the periodic behavior of the inputs, the manipulated variables (MV) are transformed into the form of sinusoidal functions. In this case, the amplitude and period of the sinusoidal functions become the surrog...
متن کاملPerformance Study of Reverse Osmosis Plants for Water Desalination in Bandar-Lengeh, Iran
Introduction: Reverse osmosis (RO) is best known for its use in desalination (removing the salt from seawater to get fresh water), but since the early 1970s it has also been used to purify fresh water for medical, industrial, and domestic applications. The aim of this research was the performance study of reverse osmosis plants for water desalination in Bandar-Lengeh, Iran. Materials and Meth...
متن کاملMembrane Modeling for Simulation and Control of Reverse Osmosis in Desalination Plants
A mathematical model of Reverse Osmosis membranes is proposed for use in the testing and comparison of control strategies in Reverse Osmosis plants. The model has been developed so that it can be used within off-the-shelf software and the parameters are simple to obtain from available plant measurements. Some simulations of the proposed model show that it correctly reproduces the expected proce...
