Marine Shipboard Freshwater Generators

Industry leading technology from Pall Corporation enables shipboard water purification from virtually any water source. Locations such as littoral waters, estuaries, rivers and harbours can exhibit extremely high-suspended solids and other contaminants which often deter ship operators from making water in these areas.

Pall’s Integrated Membrane System (IMS) freshwater generators are a combination of hollow fiber micro-filtration (MF) membranes with reverse osmosis (RO) desalination membranes in a fully automatic system.

These systems are especially suited for many types of marine platform including cruise ships, commercial and military vessels.

Pall Microfiltration Modules

Suspended solids, bacteria, protozoan cysts and viruses in the feedwater are removed by a 0.1 micron hollow fibre membrane filtration system. The pore size of the membrane controls the fraction of the particulate matter that is removed. These robust PVDF microfiltration (MF) membranes retain particulate matter, while the water and its soluble components pass through the membrane as filtrate, or filtered water. The retained solids, in concentrated form, are discharged from the membrane system as a waste stream periodically during a reverse filtration flush. This technology allows the system to cope with feedwater, which has a high concentration and wide range of suspended solids, without the need to use replaceable cartridge filters.

Pall Disc Tube™ Reverse Osmosis Modules

Reverse osmosis (RO) membranes are used to remove the dissolved salts contained in the sea or brackish feedwater. The membrane technology enables the reduction of dissolved salts in excess of 98.5 % while the Pall Disc Tube (DT) configuration with short open channel feed flow paths impart turbulent flow to minimise concentration polarisation and hence reduce membrane scaling and fouling. The compact and flexible construction gives long membrane life, easy access and lower replacement costs.

Pall Spiral Wound Reverse Osmosis Modules

Spiral wound RO modules perform the same function as DT modules but are typically applied in larger applications where flow rates are in excess of 70 m3/day. These modules feature an extremely high membrane surface area to hold-up volume ratio. Feedwater is optimally pre-treated by microfiltration in an IMS, enabling spiral wound modules to provide excellent reliability with greatest output of potable water and smallest footprint together with minimal energy use

Pall Microfiltration (MF) Stand-alone Water Treatment Systems

For vessels that already have reverse osmosis systems fitted on-board, Pall offers an MF stand alone system as an upgrade to achieve full IMS capability.

Pall IMS Freshwater Generators

Pall’s IMS systems combine MF and RO technologies arranged in a self contained automated package.

The Pall IMS technology promotes an enhanced ship board capability, availability of fresh drinking water and lower through-life cost of ownership for fresh water generation.

Integrated Logistic Support (ILS)
