“Our existing ClorTec on-site sodium hypochlorite generators were running so well, easy to use, and, most important – giving us the peace of mind of knowing we were using the safest possible technology….it just made sense to add a third one during the expansion, knowing we’re going to need it someday.”
The average flow this year has been 30 MGD, but as the communities build out and population grows, requiring more water, Andrews anticipates that they’ll need the full 48 MGD capacity.
Santan Vista WTP serves 150,000 individuals, meeting or exceeding the environmental regulations put in place by the two communities of Gilbert and Chandler. The new next generation ClorTec DN on-site sodium hypochlorite generator is another 1,500 lb./day unit. Currently, Santan Vista runs one of the three units exclusively, sufficient for today’s needs. With the increased capacity, they’re ready for a growing population.
“The ClorTec OSHG is so simple, it’s easy to almost forget it’s there,” commented Andrews on the technology. “Maintenance is minimal – we visually inspect the cells to see if there is any bridging across the plates in the cells, and we change out the filters. If bridging occurs, it requires a simple acid clean, but that doesn’t happen often. I would recommend the system based on my own experience. If you can generate on site, that’s the way to go. Definitely.”
The ClorTec DN Gen II has additional features that add to the system’s safety and efficiency include the hydrogen venting of each cell, an updated control system, a lower operating temperature, and a unique optional split flow technology to reduce energy consumption.
