UV Disinfection Sizing.
UV Disinfection Sizing.
(OP)
I have been trying to size a system to treat a 1 MGD treatment plant. The process goes as follows:
Screening
Pumps station
SBR SYSTEM
pump station
EQ Basin
UV disinfection.
I am having a hard time determining what size of UV I will need. The EQ Basin is a 0.5 MGD tank. I have considered using 3 uv units. When flows are minimal use 1 unit and when flows are higher use 2. Having the 3rd at a spare.
How should I deteermine how big the units should be. I know it is not good for the system to be turned off and on but unless I recirculate there may be no other way.

RE: UV Disinfection Sizing.
The size of the unit will depend on a number of factors including the TSS and transmissivity of the fluid.
The best way is to ask the suppliers for a data sheet. Get the information they need and then seek a performance guarantee. Your discharge license will have the parameters that you need to comply with so seek a vendor guarantee.
You will also be concerned with power draw and lamp life.
