Community, Commercial & Residential Ultraviolet Purification Systems
A new generation in UV water treatment devices, the Hallett 30 with patented Crossfire Technology for community and commercial applications outperforms conventional systems. It has the most effective UV dose for disinfection of all pathogens including viruses, bacteria, cryptosporidium, giardia, legionella and E. coli.
Flow Capacity: 30 gpm
Run in parallel - up to 600 gpm.
Pictured to the left is a 7-unit Hallett 30 Ultraviolet Purification System run in parallel and used in a municipal water system. It is a small community with about 180 homes.
The town needed a 20 minute residual time for chlorination without UV. If they used UV, they would not require any residual time. There was no physical room for the 4,000 gallon tanks that would be required for chlorination. As well, a pump would be required to draw the water from the tanks to the distribution system.
The cost of the ultraviolet system was considerably less than a chlorination system. With the Hallett system, the town got the added benefit of a second disinfection system.
The town required 180 gpm plus a redundant unit (180/30 - 6 + 1 = 7). They chose to run all seven units at once with a PLC that sends a signal if any unit goes down. If only six units are operational, they can still have a disinfected water supply knowing that six units meet their demands.
The 7-unit Hallett 30 system sized for this community proved to be the most effective option with considerable cost savings in the acquisition and for future maintenance of the system. As well, the community can rest assured that they will enjoy "Pure, safe water. Always."
Certification from NSF: NSF International is the leading authority on residential water treatment system testing.
