The flexibility of membrane contactors (MCs) is highlighted for a reverse osmosis (RO) desalination plant. MCs are applied as pre-treatment the oxygen removal and pH reduction seawater, also post-treatment increase RO permeate brine volume. A decrease seawater down to neutral values, needed when coagulation used in line RO, together with an up 7.58, matching target produced water, can be obtain...

Seawater contains a number of organic and inorganic components that cause fouling of membranes when subjected to a process of reverse osmosis desalination. This fouling is one of the most important problems in the management of desalination plants, as it entails a significant loss in system performance. For membranes to be able to continue operating under appropriate conditions, they must under...

Silica scaling is one of the major challenges in Reverse Osmosis (RO). The safe operation practice to keep silica concentration below 150 mg/L RO concentrate. This study addresses effects divalent cations such as calcium and magnesium on a seawater installation used pretreatment Eutectic Freeze Crystallisation (EFC). Results showed that absence antiscalant sustained approximately 280 concentrat...

The rotary energy recovery device (RERD) is an essential component in seawater desalination for decreasing the consumption of reverse osmosis plants. To research complex flow fields and mixing motion ducts a device, 3D numerical simulation was studied this work. Three-dimensional vortex structures were visualized identified based on Q criterion. effects operating condition structure parameter h...

Many desalination plants still struggle to control biological fouling in seawater reverse osmosis (SWRO) systems as there are no standard methods monitor this type of fouling. Strategies biofouling SWRO have been proposed such antifouling coating and lowering potential feedwater through pretreatment processes. Measuring the has gained increased interest due its direct link biofouling. Moreover,...

Reverse osmosis (RO) technology has been widely applied to water treatment such as seawater desalination, and large RO plants are many in operation around the world. Moreover, much larger plants will be required to secure sufcient water resource in the near future because global water shortage and quality problems are still getting more serious. Mega-ton Water System pr...

forward osmosis (fo) has recently drawn attention as a promising membrane based method for seawater and brackish water desalination. in this study, we focus on the use of calciun chloride (cacl2) and potassium bicarbonate (khco3) as inorganic salt draw solution candidates due to their appropriate performance in water flux and reverse salt diffusion as well as reasonable cost. the experiments we...
