The Challenge
Planned Brackish Water Reverse Osmosis (BWRO) facility facing significant drop-off in water quality.
The City of North Point, Florida built a new brackish water reverse osmosis (BWRO) facility capable of producing 2.0 MGD of potable water by treating raw water from local wells with a Total Dissolved Solids (TDS) level of about 3,500 mg/L. However, the facility needed a flexible design because the conditions are expected to change over time. Nearby wells are degrading and the City anticipates that the raw water quality will degrade over time; historical data predicts salinity could increase by as much as 370% in the first 10 years of operations. The facility has two reverse osmosis (RO) skids, each capable of producing 1.0 MGD, which are designed to expand to produce 2.5 MGD each as demand for water rises. This wide range of operating conditions presented a significant design challenge.
