Rick, Eric, and the entire team at Absolute Water Technologies are consummate professionals in water treatment. They have installed two (2) RO/DI systems for our businesses in Missouri and Wisconsin. Both projects were completed on time and in budget and final purity specifications were met easily on both systems right at startup. Service after the sale has been top notch, and both systems are performing perfectly 18 months after installation. When the time comes for us to expand/upgrade either of our systems, I would not hesitate to work with them again.
