Seaclean Filter

Pressurized multi-media filtration for the clarification of seawater

The Seaclean filter is designed specifically for the desalination of seawater. It integrates within a system of seawater desalination to increase the life of reverse osmosis installations by protecting the core of reverse osmosis membranes.  Employed as a pre-treatment, it can be used on facilities of all sizes.

The Seaclean filter integrates within a system of seawater desalination.

This two-layer filtration technology (anthracite + sand) takes place on one level before reverse osmosis, and it may be preceded by dissolved air flotation clarification for water presenting occasional peaks in organic matter and algal blooms. 

An optimized cleaning that reduces water loss 

The Seaclean filter is a pressurized horizontal filter, therefore filtration occurs with a downward flow through 2 layers of media: 

  • an upper layer of anthracite, the larger media, that captures suspended matter, 
  • a lower layer of sand, the finer material, which reduces the SDI (Silt Density Index) and therefore the risks of reverse osmosis membranes fouling. 

To maintain filtration efficiency, backwashing of filters is required. It is done in 2 phases: the air phase lifts off impurities and is completed by a water phase to discharge sludge and realign media layers mixed together during the air phase.

What it can do for you 

  • Quality and protection: The quality of filtered water is stabilized and guaranteed before the reverse osmosis phase. The risk of media loss is minimized. 
  • Performance and economy: A process that augments the performance of reverse osmosis. Less equipment cleaning means water loss is reduced. 
  • Flexibility: A process adapted to facilities of all sizes.
