Large water plant needed an update to reduce electricity and carbon footprint
In Sarroch, on the southern coast of Sardinia, lies the largest ultrapure water plant in the Mediterranean. Built by ACCIONA Agua in just six months, the containerized twopass SWRO plant provide the demineralized water for the steam needed to drive the Sarlux power plant turbines and keep the Saras refinery in operation.
Compact Danfoss APP pumps, iSave ERDs, VLT® AQUA Drives, and pressure transmitters enabled operators to save an impressive 88% in energy consumption compared to the old distillation system. The Saras refinery and Sarlux power plant needed to update their shared ultra-pure water plant, which produced 24k m³/day. Not only did the aging distillation plant depend on a combination of SWRO and surface sources on water-starved Sardinia, its energy consumption was massive. And while electricity might be “free” for a power plant, the outsized energy bill represented a significant opportunity cost in lost sales revenue – not to mention a heavy carbon footprint.
