Hmm, well, yes, the long and the short of it is that the clumping of microorganisms is not a valid explanation. There is no link between lethal dosage of UV and physical or mechanical clumping. Irradiating germs with UV does not initiate any mechanical merging of the germs. It either kills them outright, or it prevents them from reproducing. If germs clump together it has no bearing on how the radiation works and would be a downstream, or indirect consequence. So my point is that UV kills things outright. It cannot be an adjunct to mechanical filtration. You cannot get rid of germs that way unless your filter media is made of micro-pores such as in an RO filter. That unit mechanically removes germs because the pore size is the size of a water molecule.
Germs have been around for about 4,000,000,000 years
Ultraviolet Radiation has been around for about 13,500,000,000 years.
So, for 4,000,000,000 years, UV has been killing germs in the manner described in post #17 whether you like it or not, or whether you understand it or not. UV has never killed germs by clumping. So 30 years is a mere pittance by comparison.
Cheers,
Well, here are some more annoying technical facts:I am not sure how many years of experience you have had with the installation of UV filters but I have had about 30 & I can only offer my personal advice.
