Biofoulants by autopsy of RO membrane and microbiological quality of the intake water were investigated with the samples obtained from existing RO desalination plant. The analysis of organic matters of the biofilm on the membrane surface showed that macromolecular substances such as proteins and car

This study investigated effects of the concentration of ball clay suspensions and different filtration modes on the fouling of a submerged module (YEF; Yonsei End Free). In a crossflow filtration mode, short filtration time could reduce the membrane fouling at the one-minute stop duration. In order

In this paper the performance of single and dual media filters with in-line flocculation have been examined as pretreatment to seawater reverse osmosis (SWRO). A comparison of filter performance was made between single medium filter (80 cm) consisting of sand or anthracite, and dual media filter con

The removal of particulate matter and dissolved organic matter from seawater by the use of biofiltration was investigated. Granular activated carbon (GAC) and anthracite were used as biofilter media at two different filtration velocities. Filtrate quality was measured in terms of silt density index

Concentrate staging which is one of the configurations of reverse osmosis membrane system has made hybridization of different types of membranes such as sea and brackish water reserve osmosis membranes possible. And the essence of hybridization of membranes is to equilibrate permeate and lower energ

In this study, titanium tetrachloride (TiCl4), titanium sulfate (Ti(SO4 )2 ) and ferric chloride (FeCl3) flocculation as a pretreatment to seawater reverse osmosis (SWRO) were investigated. Their ability to remove turbidity, seawater organic matter (SWOM) and controlling the feed water quality of SW

MF/UF has been recently applied as a pretreatment process due to its high removal efficiency of fouling matters in Reverse Osmosis (RO). This study evaluated the effect of coagulation on the performance of MF and UF for removal of particles with two kinds of membranes under various coagulant dose an

One of the key transport parameter—permeability, is being used as an intrinsic characteristic of membrane for reverse osmosis process prediction. In this study, the prediction of reverse osmosis process in terms of boron rejection was carried out in two steps. First, the permeability of boron existi

An optimal system design as well as advanced fault tolerant control is required to propose a cost-effective design and control of a seawater reverse osmosis (SWRO) desalination plant. Contrary to the steady-state model which is useful for only design, a dynamic model is essential to complete a plant

Hybrid processes combining fibre filter with deep bed filtration process such as (i) fibre filter and sand filter, (ii) fibre filter and anthracite and (iii) fibre filter and dual media filter were investigated as pre-treatments to SWRO. Seawater was drawn from Chowder Bay, Sydney. The effect of dif
