Hello ,As per UV protocol EPA/NWRI/IUVA recommended dosage is 30000uw-s/cm2 for 254NM UV lamp.BOD /TSS for effluent should be less than 10 mg/l and Total coliform 2.2 per 100ml for 7 days maximum should be maintain.

Mr. Nazeer - I see that you are still using the horrible units of uw-s/cm2. 30000 uw-s/cm2 is the same as 30000 uJ/cm2 or 30 mJ/cm2. When you state a number to 5 significant digits, it is implied that the measurement is accurate to a few parts in 30000, which is certainly not the case here. In modern scientific studies, a UV dose (proper term fluence) should be stated as 30 mJ/cm2.

Assuming conventional treatment, We decide on how much LRV reduction ( Maximum 4) required for Crypto. Given the design flow and design UVT, reduced equivalent UV dose required (mJ/cm2) can be deduced from the table of UVT vs. required UV power.
