Hello Tahir,

SDI does not have any relation with fouling potential. If you want to measure fouling potential, better use the MFI method, Modified Fouling Index. Suggest you to contact Akvoregia for more and detailed information their MFI Forecaster and the topic of TEP. With their instrument you can also assess effectiveness of your pretreatment process.  Alos a prediction of fouling potential of feedwater before RO systems is easy and possible. When you know the fouling potential, you can adjust your process ( more or less backwashes), which leads to better performance, of your system. Also corrupt pretreatment systems can be determined. TEP will always occur in your water, but you get better control over your process. Send email to me if you need more info. Best regards, Roemer
