Problem: With 16 mgd capacity, the Newport (Rhode Island) Water System draws from nine surface reservoirs. When one aboveground tank experienced high trihalomethanes, the city sought remedies. While exploring an alternative to carbon filtration pressure vessels, the city required a performance guarantee of 50% average total THM removal for the new solution.
Solution: The city chose a PAX TRS THM removal system from USG Water Solutions. The company installed a custom-designed, energy-optimized system of mixers, aerators and ventilators to convert water storage tanks into water treatment systems. The solution consists of a PWM400 mixer, two SA-75 surface aerators, a PPV-600 Powervent
