SIRION Advanced for H2 battery production plant

| The client’s needs

For the operation of its hydrogen fuel cell production plant, a European leader in the construction industry has entrusted Veolia Water STI's Process Water Department with the construction of an ultra-pure water production, storage and flow/return loop unit.

| The solution

The installation consists of four SIRION ADVANCED osmosis water production units followed by two AQUADEM ion exchange resin cylinders. A microfiltration stage completes the production of this ultra pure water.

| Process description

• Fine filtration on cartridge
• Sequestrant injection unit
• Bisulphite injection
• Disconnection tank
• Storage
• Two loop outlets equipped with resin cylinders
• 4 osmosis units (2 in parallel and 2 in series)
• Various automatic safety devices allowing operation on only one osmosis line if necessary (the first or the second) or directly on the resin cylinders

| The result

The design of the production line allows for continuous production of doubly osmosed water, even in the event of maintenance or failure of one of the osmosis units.
Low energy consumption due to the recovery of part of the waste water and the use of mixed resin cylinders.

"Decarbonising industry by developing a French hydrogen production and use sector is one of the priorities of the national energy strategy. Electrolysis requires ultra-pure water. This is the expertise that Veolia Water STI brings to this emerging sector." Jean-Claude CELANI, Head of Process Water Activity at Veolia Water STI
