Interior of a Desalination Plant

Join Sulzer experts, Mario Alvarez Sánchez and Shane Hartley, as they explore a Sulzer pump retrofit at a Spanish desalination plant which: Achieved best efficiency point (BEP) at half original flow rate

  • Reduced CO 2 emissions by thousands of tonnes
  • Lowered pump energy consumption by nearly 1,000 kW each
  • Avoided a resource intensive pump replacement
  • Unlocked a large operating expenditure (OPEX) saving

Sulzer’s retrofit technologies allowed oversized pumps to be re-rated to deliver the new flow rate in the most efficient way possible, ensuring the ERD upgrade was achieved with minimal modifications to the plant.


In the upcoming webinar, Sulzer will delve into the intricacies of optimising plant overhauls with a specific focus on Energy Recovery Devices (ERDs). The spotlight will be on the cost-effective strategies employed in retrofitting pumps during the upgrade of ERDs within a saltwater reverse osmosis (SWRO) desalination plant.

A plant overhaul involves a comprehensive and systematic examination of an industrial facility to assess its condition and performance. This process often includes disassembling, repairing, and upgrading various components to enhance efficiency, reliability, and overall operational effectiveness. An integral aspect of plant overhauls is the evaluation and potential replacement or enhancement of energy recovery devices (ERDs).
