en.Wedoany.com Reported - Al Mawarid Pumps Assembly Water Solution has successfully designed and delivered a 450 m³/day marine reverse osmosis seawater desalination system for the livestock carrier Saphira, featuring Energy Recovery's PX Q180 pressure exchanger and HP1254 high-pressure booster pump. The system was installed and commissioned during the vessel's brief transit stop in UAE waters.
The Saphira was originally equipped with a 200 m³/day seawater desalination system without energy recovery, resulting in high specific energy consumption per cubic meter of freshwater produced. During the vessel's redeployment, the operator required increasing the output capacity to 450 m³/day while maintaining the original engine room space and total power range. Additionally, installation and commissioning had to be completed within the limited time the vessel was docked at Dubai's Port Rashid.
To meet stringent space constraints, Al Mawarid selected Energy Recovery's PX Q180 and HP1254 high-pressure booster pump combination. The booster pump was installed above the high-pressure pump, optimizing vertical space utilization, and the compact skid-mounted integrated configuration enabled the system to be installed within the planned timeframe. This combination helped the system achieve a low specific energy consumption of 2.51 kWh per cubic meter of freshwater.
Ebrahim Al Tenaiji, Managing Director of Al Mawarid Pumps Assembly, stated that doubling freshwater production capacity without increasing power supply or footprint, within an extremely limited time window, was made possible by the PX Q180 and HP1254. The system operates stably, with energy consumption data fully meeting expectations.
After the retrofit, the desalination system's capacity increased from 200 m³/day to 450 m³/day, all achieved within the existing engine room space. Based on operational data, it is estimated that annual electricity savings of 518,000 kWh can be achieved, corresponding to cost savings of approximately $51,800.
Livestock carriers have stringent freshwater supply requirements directly related to animal welfare, but limited onboard mechanical space and power make efficient, compact energy recovery devices essential. The Saphira retrofit case demonstrates that the combination of pressure exchanger and high-pressure booster pump can deliver reliable performance in demanding environments. This solution can serve as a reference for operators rebuilding or upgrading onboard water systems, enabling capacity doubling and energy reduction without redesigning the engine room.
