Screen Filtration for Ballast Water Treatment Applications - Cross ...

Filtersafe® ballast water
Operating Pressures.
Due to the unique design of Sintered Screen and Proximity Nozzle®,
the Filtersafe® automatic filter is the only self-cleaning filter on the
market capable of sustained smooth operations as low as 1.6 Bar
(22psi) head pressure. Even at such extreme pressures, our Proximity
Nozzle® still allows 100% cleaning of the screen after each flush cycle,
ensuring continuous, uninterrupted filter operation without any risk of
‘blindness’.
Filtration Effectiveness.
Filtersafe® technology is designed to combat seawater’s marine bioinvasions,
Phyto- Zooplankton and general suspended solids. Filtersafe
BSF-series filters are offered down to 25 micron for BWT applications.
Component Durability.
Filtersafe® products have been engineered for performance and
longevity. Our automatic screen filters employ highly-durable, noncorrosive
components inside and out, to ensure robust, trouble-free
operation, requiring minimal maintenance. Filtersafe® also equips its
filters with minimal plastic materials, thereby abiding by ship-building
regulations regarding fire prevention.
Epoxy-phenol Coating.
Filtersafe® treats the body of its filtration systems with a complex
multi-staged curing process, which during development testing
logged over 2500 continous hours in a salt-cell study.
The process includes a zinc-phosphate treatment and an electrostatic,
oven-cured epoxy-phenol finish, which results in a durable protective
layer especially suited to the various rigours of marine applications
and adverse-saline-conditions. The process complies with numerous
international performance standards, including ASTMB-117.
Turbo TM Model.
All Filtersafe automatic screen filters can be equipped with our unique
Turbo TM technology. Designed to increase the filter’s capability to
operate in high dirt-load situations, this unique facility gives our
BSF-series filter a distinct market advantage in adverse, but equally
common, sediment-rich environments.
Conversely, our Turbo TM technology also allows us to equip our filters
with both nominal and absolute screens down to 25 micron for
increased removal rates.
