Design calculations are available in membrane manufacturer web sites

Mallikarjuna, design calculations are very dependent upon the feed water conditions and UF and RO supplier. Typical UF design flux is 250 to 400 LMH/bar. They actually produce greater flux but designers allow for membrane degradation and irreversible fouling during the course of the membrane lifetime. For R.O. please take a look at the Dow website which gives a variety of influent condictions and operating parameters: http://www.dow.com/webapps/lit/litorder.asp?filepath=liquidseps/pdfs/noreg/609-02054.pdf&pdf=true
