Brotherhood Mutual realized a payback period of less
than four years with their ozone system.
Brotherhood Mutual Insurance sought out CleanWater
Ozone to provide a water treatment system which could assist their
ailing 1000-gal., 150-ton cooling tower. Fouling problems due to
high algae and bacteria content were reducing efficiency and corroding
the tower ’s components.
The company stated four objectives which had to be
- To reduce handling hazardous chemicals by their
- To provide better algae and bacteria control.
- To reduce the future operating costs.
- To reduce water consumption.
The resulting design consisted of an ozone system
to treat the circulating feed water. Daily tests showed the cooling
water quality to be more stable than when using chemicals. The condenser
vessels are cleaned annually and the condition of the copper tubes
is reported as “excellent”. A cost analysis was completed
after four years of operation and the system was found to have paid
for itself midway through the fourth year. The system is about to
complete its tenth year in operation.
The building manager, Phil Doege, recently wrote
us with the benefits achieved.
- Our maintenance crew handled 305 gal. of chemicals
a year to treat our cooling tower and 1000 gal. sump
tank. This potential problem has been eliminated.
- Ozone is regarded as one of the best bacterial & algaecide
treatments available, but several contractors and suppliers
we talked with had not come up with a system that was
cost effective and worked well until we talked with CleanWater
personnel. Their system is simple, cost effective and
it works. Our cooling tower has been algae-free since
installing the ozone water treatment system. What more
could you ask for!
- . . .after [the system paid for itself] the cost of
operating the system is electrical usage and maintenance.
- A 4th benefit for our company was reduced water consumption
at bleed off to control our dissolved solids.
I think the CleanWater Ozone system offers a better
choice for algae and bacteria control while eliminating chemical
hazards and reducing operating cost.”
