A bright future

According to Dussert, UV water treatment R&D is currently
focused on reducing the overall cost of operations.

“Extending the life of the lamp beyond 15,000 hours is the

name of the game,” he says. “Moving forward, we could see

electrode-less lamps that could last 30,000 hours or more.”
