Supply of ultrapure water for a 20 MW AEL electrolyser

Project requirements

A containerised ultrapure water solution was required for a hydrogen project in Saudi Arabia. Key requirements included a compact design, high operational reliability, consistently low conductivity levels, and a solution that could be reliably installed, operated and maintained under export conditions. In addition, the system was required to ensure high water quality during continuous operation whilst operating in a resource-efficient manner.

Herco solution

A customised containerised system was developed that combines high water quality with a compact design and easy access for maintenance. Through carefully coordinated engineering, a reliable ultrapure water solution was created for continuous operation, featuring optimised energy and water consumption and a design that ensures stable processes under demanding operating conditions.

Plant engineering

The system was designed as a compact containerised solution for the reliable production of ultrapure water and combines high-performance treatment stages with secure storage and targeted post-treatment.
