Fouling index

1 - 5 of 5 results

A membrane fouling index such as the silt density index (SDI) and modified fouling index (MFI) is an important parameter in design and operation of reverse osmosis (RO) and nanofiltration (NF) membrane processes for desalination.

... molecular weight distribution (MWD). The efficiency of the filter as pretreatment was evaluated in terms of silt density index (SDI) and modified fouling index (MFI). It was found that the turbidity removal was high and all the filters produced more or less same quality water. There was a slowe ...

... was higher than that of temperature. The highest flux was measured at 40°C. There was no appreciable difference between 30 and 40 bar. The fouling index, calculated by fitting a power function to the measured data, was mainly affected by the temperature: it decreased with increasin ...

... from Chowder Bay, Sydney. The effect of different pretreatment hybrid systems was investigated in terms of silt density index (SDI10), modified fouling index (MFI), headloss across the filters and reduction in turbidity and dissolved organic carbon (DOC). The in-line flocculation in fibre filte ...

... that with widely fluctuating raw water chemistry, the Gulf seawater which predominantly operates on open intake is more susceptible to biological fouling and algae growth thereby forcing plant downtime. In such a scenario, one often encounters with prohibitive water cost and probable mechanical... from energy saving by as much as 18%, one of the basic benefits is significant reduction in downtime. Keywords: Pretreatment technologies; Fouling index; Magnetic fields; Economics 1. Introduction Till date one of the major weaknesses of the conventional pre-treatment systems consisting of pressur ...
