The desalination plant on the Grand Cayman Island is undergoing a retrofit and upgrade of desalination technologies, using PX Pressure Exchanger energy recovery devices.
Energy Recovery’s PX devices will help Consolidated Water, who built the desalination plant, and the Water Authority-Cayman to cost-effectively deliver more than 4,900 m³ of potable water per day. The PX devices have been chosen to replace the existing DWEER units based on their reliability and overall lifecycle costs.

Borja Blanco, senior vice president of Energy Recovery Inc said: “SWRO desalination has been an integral part of Grand Cayman’s water supply for years but in order to sustain the process long-term it is important that the cost of producing potable water be kept to a minimum. Downtime due to equipment failure is a dual problem in a desalination facility, as you have to spend time and money to resolve issues, while your revenue stream is interrupted by the lack of production. We are pleased that Consolidated Water has selected Energy Recovery’s PX devices as an upgrade to the existing DWEER units.”
