Energy Saving Retrofit for Enhanced Plant Capacity at Red Sea Resort

Safa Water Technology provides water for consumption by hotels and resorts near the Red Sea with two reverse osmosis (RO) plants. Before the retrofit, each plant had a production capacity of 500 m³/day and a high specific energy consumption of 6.3 kWh/m³. The plants had existing energy recovery devices (ERDs) with reliability issues, including turbine failures. To increase production capacity while lowering the energy requirements and costs, the company collaborated with Interwater, which helps install and operate desalination plants, to implement a retrofit.

The engineers at Interwater chose to employ Energy Recovery’s PX^® Pressure Exchanger^® devices. Focusing on enhancing energy efficiency, the plants successfully reduced the specific energy consumption by 55%, allowing them to increase water production while saving money.
