Prediction of the behaviour of the Silt Density Index (SDI) in the Caribbean Seawater and its impact on RO desalination plants

Effect of microbubbles on microfiltration pretreatment for seawater reverse osmosis membrane

“…SDI is one of the most commonly used measurements to estimate treated water quality [29]. The silt density index (SDI according to ASTM) is a useful tool for particle evaluation and by extension, membrane fouling [28,30].…”

“…It is a measure of colloidal/particle fouling [26,[28][29][30]. The treated water samples from the MF membrane were tested by the SDI 5 prior to any RO tests in order to compare the water quality of each sample at a different pretreatment time (raw seawater/raw seawater-FeCl 3 /Mbs/Mbs-FeCl 3 / Mbs-FeCl 3 /Mbs-FeCl 3 -MF).…”

Simulation of Reverse Osmosis Process: Novel Approaches and Development Trends

“…In certain works, the other approaches, which cannot be related to the described above groups, were applied. Those models can be based on the empirical data (both with and without combination with conventional models) [329][330][331][332][333][334][335][336], the mass and energy balances [337][338][339][340][341], the Monte-Carlo method [342][343][344], the concentration polarization models [345][346][347] and osmotic pressure [348], the boundary layer theory [349], the dynamic modeling [350], the materials flow analysis [351], the risk and fault analysis [352][353], the numerical methods [354], the chemical kinetics and equilibrium [355], or its combinations [356]. However, such investigations were low numerous and it does not seem possible to define some of them as perspectives.…”
