Ultrapure water for 50 MW PEM electrolyzer

Silhorko-Eurowater has designed and manufactured the water treatment solution for the world’s first large-scale commercial e-Methanol production facility commissioned by European Energy.

The hydrogen is being supplied by a 50 MW PEM (Proton Exchange Membrane) electrolyzer plant by Siemens Energy that requires a steady supply of 10,000 litres of ultrapure water per hour with a conductivity below 0.1 μS/cm.

The water treatment solution includes the EUROWATER reverse osmosis unit type RO-PLUS with high-recovery technology. The unit excels by saving both water and energy, achieving a water recovery rate of 90%, and is equipped with energy-efficient e-pumps from Grundfos.
