Type 45 Daring-class destroyer,

BAE Systems has selected Pall to deliver freshwater generator systems for the UK Royal Navy’s Type 45 Daring-class anti-air warfare destroyers, to allow them to effectively conduct operations even in coastal waters.

Pall-built integrated membrane system (IMS) / freshwater generator system has been designed to generate clean water from several water sources, including open sea, coastal areas, rivers and harbour areas.

BAE’s Type 45 class output management team head Tom Quaye said: "It is essential that these ships can produce fresh water wherever they are operating; we were very pleased with the performance of Pall’s IMS for delivering fresh water supplies during the ship’s deployment."

The fully automatic system has validated its ability to transform highly contaminated coastal waters to pure water during demonstrations at sea.

"The IMS has operated successfully at many military, commercial and disaster relief sites around the world.”

In addition to reducing maintenance tasks, the cleanable IMS will lower the cost of ownership when compared with traditional water treatment systems.

The IMS freshwater generator features hollow fibre microfiltration (MF) and reverse osmosis (RO) modules to eliminate suspended solids, such as bacteria and viruses, dissolved components ,including salts, and other contaminants from sea water.

Capable of reducing the need of spare filter cartridges store, the system can be used to enhance water production on a permanent or temporary basis.

Pall Aerospace president Vince Northfield added: "In addition to implementation with UK’s Royal Navy ships, the IMS has operated successfully at many other military, commercial and disaster relief sites around the world."

Designed to replace the Type 42 frigates, which have been operational with the Royal Navy since the mid-1970s, the Type 45 destroyers have a displacement capacity of 7,350t and can cruise at speeds of around 33mph while carrying a crew of 235.
