The City of Palm Coast, FL was experiencing elevated color in the concentrate stream being directed to the lime softening facility to recover as drinking water. In an effort to meet secondary color standards at the lime plant, this water quality issue limited the volume of the concentrate able to be recovered.
The City installed a new Pinnacle Summit™ Series ozone system to reduce the organic based color of the low pressure RO system concentrate stream. In an innovative and unique treatment application, this ozone pre-treated concentrate stream is directed to the City’s lime softening facility and processed as an alternative water source.
In preliminary startup and testing, initial results of the ozone treatment system have met and exceeded performance goals. Pinnacle provided a complete and fully integrated ozone system including an onsite oxygen generation system, side stream injection, closed loop chiller, and an off gas ozone destruct unit. The entire system was delivered and substantially completed in less than 12 weeks in order to meet the deadlines for project funding.
