question for the plumbing pros

shoefreak03, follow this link.. it can help you estimate the flow rate of the water.

Hope this helps. It helped me a lot.. passing it on.

Wow . . . a lot of interest in UV sterilization these days!!

I've spent the past 1 1/2 years researching & testing UV Sterilizers and have found a lot of false & misleading info out there.

It looks like your UV runs directly from the outlet of the pump . . . flow rate is critical, so generally a by-pass would be used whereby a portion of the water passes over the UV tube at the optimal speed and the rest goes directly back to the tank.

It's the third time I've posted this tonight, but I highly recommend P.R. Escobal's manual (try the library). His info is technical, but it shows you how to determine the proper flow rate for various sized tanks & categories of pathogens and algae.

Speaking of flow rate (and it is a must that you know exactly what it is) Oscar / Tom makes a great gauge that sells for under $20

I hope this is helpful.

can you attach a link to the flow rate gauge you are referring to?

if the UV chart will have info on flow rate. the pump must either be equal or lower than the uv can handle to have the full effect. flow rate gauge will slow the flow rate for sure but it's an option.

As I posted earlier to another thread...

"seems you like P. R. Escobal's work. but i would say... UV technology has greatly improved in the past 7 years. the 1st ed of escobal was in 1996 and the second one was 2000. Seven years ago is quite long i would say... the books cost more than $200. hopefully it is easily seen in libraries. with 206 pages... wow! i would go for the flow rate on the manufacturers manual. they cannot falsify those as they are liable to law suits if it was incorrect."

also his book AQUATIC SYSTEMS ENGINEERING p.r. escobal isbn 1-888381-10-8 is GREAT a little techy

http://www.tomaquarium.com/ is the Oscar / Tom Home Page

Click on "Products" in the left column. The Flow Gauge link is near the bottom.

I hope this helps - - the gauge has 3/4" inlet & outlet, so the restriction is nominal considering the flow rates being used.

Yes, I do like Escobal's work & did re-post in the other thread.


Cheers,

Terry
