      Custom High Flow UV Light...

      I have a customer that wanted me to create a complete plug-n-play filtration system that would fit into a pretty tight space. I decided to create a UV light that was also an water distribution manifold so it would have dual purpose. It has three 3" tangential inlets, and ten 2" underwater pond returns...

      The electrical connections are the standard 4-pin that you see on most UV lamps...

      This is the quartz sleeve support that is 2/3's of the way down the filter...

      The UV Lamps are 36" long and have the following specs...

      The replacement costs for the lamps will be $55 each and with a lifespan of 16,000 hrs (666 days) equates to $30 per year.

      I have a limited stock right now of only 50 lamps and quartz sleeves, but I plan on ramping up production next year and introduce a high flow, low head loss UV clarifier that will have UV-C wattage than the EVO series and have a much lower head loss due to increased inlet/outlet sizing. More info to come.

      Beautiful work!

      What size are the 3 pumps feeding it?

      They are ArtesianPro 1/3hp pumps, and I am expecting a total flow of 20K

      Sometimes I just have to admit when I pushed things a little too far. This 380 watt UV Clarifier was getting an actual flow rate of 18,000 GPH, and there was a slight greenish hue that remained in the pond. So obviously I was not getting enough dwell time in this unit to completely stop the reproduction of the algae. The algae wasn't that bad, but with the amount this customer paid for their pond, I wanted crystal clear water. I know I had enough total UV-C wattage on this unit for that 18K gph flow rate, but the problem was with the fluid dynamics inside the filter. The water wasn't staying inside the filter long enough to get the dwell time needed. So I decided to make another filter body, and only connect it to two of the water pumps this time, just for extra safety and dwell time. The existing unit had the quartz tubes removed and caps installed on the electrical side of things, and was left in place to be a distribution manifold for the three pumps and the many underwater return lines.

      I constructed this filter with tangential 4" inlet and outlet, so all of the water spins around UV lamps as it travels the length of the filter. This gives maximum dwell times and ensures that all air bubbles are spun out of the unit. I upgraded business end of the filter so that you had complete access to the inside of the filter. This way if a quartz tube broke, you could easily remove all glass by unbolting the flanged end. I also improved on the quartz tube seals and electrical connections to make things more secure. The customer had to swap over the ballasts, quartz tubes, and lamps into the new unit and after the install the water was crystal clear in 24 hrs and I had a very happy customer!

      Here is the old unit...
