Filtration of the world’s water:<br />
we set the standards.<br />
Earth isn’t called the Blue Planet for nothing. Over seven tenths of the<br />
surface of our globe is comprised of oceans, seas, great and small lakes<br />
and the networks of natural and man-made waterways and reservoirs<br />
embroidering the landscape.<br />
Taking care of our water and providing solutions in filtration and<br />
treatment is the principal challenge facing <strong>Filtersafe</strong>®, one of the<br />
world’s leading filtration specialists. Whether across industrial,<br />
marine or resource drilling applications, our aim is to ensure<br />
the world’s industries have ready access to the most advanced<br />
filtration equipment available.<br />
At the onset of each design application, <strong>Filtersafe</strong>’s primary objective<br />
is to engineer and fabricate tailored and standard filter systems from a<br />
range of highly sophisticated and proven materials, utilizing major R&D<br />
initiatives to establish the most appropriate specification of materials<br />
to ensure each finished product exceeds all mandated requirements.<br />
At the very core of <strong>Filtersafe</strong>’s development philosophy, is a consistent<br />
and dedicated focus on mechanical reliability and efficiency, too, all<br />
combined with robust construction technologies. Simultaneously,<br />
our emphasis commercially remains on the careful balancing of<br />
environmental issues, alongside achieving consistent operational<br />
economies for our customers.<br />
<strong>Filtersafe</strong>® uses expertise developed over three decades in the design,<br />
manufacture and application of high quality filtration solutions. It is<br />
our often unique innovation that has helped the company contribute<br />
enormously to the efficiency of world water management.<br />
The company is uniquely positioned in the marketplace, and currently<br />
services all major international markets from its Head Office and<br />
manufacturing facility located in northern Israel.
ltration technology.<br />
Meeting the needs of the oshore oil industry<br />
by enhancing oil recovery while solving water treatment problems.<br />
The <strong>Offshore</strong> frontier is considered to be one of the most demanding<br />
industries that society relies on today. We demand economical,<br />
environmental and production performance, from a frontier exposed<br />
to the elements, forcing an industry where reliability and durability is<br />
essential.<br />
Drawing on our experience in the Ballast Water treatment sector,<br />
<strong>Filtersafe</strong>® is proud to offer established and proven marine-based<br />
technology to the <strong>Offshore</strong> industry.<br />
We understand that clean water is essential to maximize the<br />
productivity of the producing oil reservoir. For instance, suspended<br />
solids have major negative effects on the permeability of the oil well,<br />
which results in significant reduction in oil production and the lifetime<br />
of the producing well.<br />
Due to <strong>Filtersafe</strong>’s successful performance in separating suspended<br />
solids from sea water down to 20 micron and especially with removal<br />
of Zooplankton and Phytoplankton our filtration systems are highly<br />
useful for well water injection water, pre-filtration for RO systems and<br />
other applications related to the offshore industry.<br />

Sintered Screen. Weave-Wire Technology.<br />
By utilising unique and exclusive weave-wire sintered screen<br />
technology, <strong>Filtersafe</strong>® obtains unparalleled Zooplankton removal<br />
rates. <strong>Filtersafe</strong>’s fine screen is composed of four sintered, stainless<br />
steel screen layers that create a strong, durable, reinforced filtering<br />
element, which requires no support.<br />
Two types of stainless steel are available:<br />
• 316L, for standard applications.<br />
• 904L Duplex SST, for high-corrosion resistance and prolonged filter use.<br />
<strong>Filtersafe</strong>’s superior Sintered Screen Weave-Wire technology gives<br />
OFS-series filters a distinct advantage over the competition. Our<br />
filtration performance is second-to-none and in terms removal of<br />
organic matter and TSS.<br />
For instance our 40 micron screen removes 98% of Zooplankton and<br />
up to 50% of Phytoplankton from water intake. This performance<br />
level is converted into exceptional sediment removal performance.<br />

Close Proximity Suction Nozzles®.<br />
<strong>Filtersafe</strong>® utilises its Proximity Nozzles® patented technology<br />
to efficiently and effectively remove organic matter from the<br />
filter screen without having to halt system operation.<br />
This completely autonomous system uses calibrated<br />
suction nozzles which cover less than 1% of the total screen<br />
area to remove screened matter. This results in extremely<br />
high suction forces that ensure complete cleanliness in<br />
preparation for the next cycle and establishing it as up to<br />
50% more effective than the traditional ‘candle’ system.<br />
The Proximity Nozzles® enable a regulated and consistent<br />
suction force to clean the screen. This resourceful hydraulic<br />
system ensures maximum suction force for removing dirt<br />
from the screen whilst minimizing residual water and pressure<br />
loss from the cleaning process, consequently <strong>Filtersafe</strong>® uses<br />
a significantly lower amount of ‘wasted water’ during the<br />
filtration’s flushing process.<br />

Operating Pressures.<br />
Due to the unique design of Sintered Screen and Proximity Nozzle®,<br />
the <strong>Filtersafe</strong>® automatic filter is the only self-cleaning filter on the<br />
market capable of sustained smooth operations as low as 1.6 Bar<br />
(22psi) head pressure. Even at such extreme pressures, our Proximity<br />
Nozzle® still allows 100% cleaning of the screen after each flush cycle,<br />
ensuring continuous, uninterrupted filter operation without any risk of<br />
‘blindness’.<br />
Filtration Eectiveness.<br />
<strong>Filtersafe</strong>® technology is designed to combat seawater’s marine bioinvasions,<br />
Phyto- Zooplankton and general suspended solids.<br />
Component Durability.<br />
Using our extensive knowledge in the field of seawater applications,<br />
<strong>Filtersafe</strong>® products have been engineered for performance and<br />
longevity. Our automatic screen filters employ highly-durable, noncorrosive<br />
components inside and out, to ensure robust, trouble-free<br />
operation, requiring minimal maintenance.<br />
Epoxy-phenol Coating.<br />
<strong>Filtersafe</strong>® treats the body of its filtration systems with a complex<br />
multi-staged curing process, which during development testing<br />
logged over 2500 continous hours in a salt-cell study.<br />
The process includes a zinc-phosphate treatment and an electrostatic,<br />
oven-cured epoxy-phenol finish, which results in a durable protective<br />
layer especially suited to the various rigours of marine applications<br />
and adverse-saline-conditions. The process complies with numerous<br />
international performance standards, including ASTMB-117.<br />
Turbo TM Model.<br />
All <strong>Filtersafe</strong> automatic screen filters can be equipped with our unique<br />
Turbo TM technology. Designed to increase the filter’s capability to<br />
operate in high dirt-load situations, this unique facility gives our<br />
OFS-series filter a distinct market advantage in adverse, but equally<br />
common, sediment-rich environments.<br />
Conversely, our Turbo TM technology also allows us to equip our filters<br />
with both nominal and absolute screens down to 10 micron for<br />
increased removal rates.<br />

Actively preventing accumulation of Sediments.<br />
<strong>Filtersafe</strong>® has recently concluded scientific tests in association with<br />
BaWaPla and NIOZ in order to determine the BSF-series filter’s ability to<br />
reduce sediment load in BWT systems and ballast water tanks.<br />
Test Methodology<br />
<strong>Filtersafe</strong>® chose the wet volumetric TSS loading method rather than<br />
the standard dry and weighing method in order to best simulate true<br />
conditions in ballast water tanks.<br />
Sediment Test Results<br />
Results of this study parallel a series of tests performed at NIOZ and<br />
Newcastle University (UK), concluding that <strong>Filtersafe</strong>® BSF-<strong>Series</strong><br />
filters are highly effective in removing Total Suspended Solids (TSS)<br />
loads by up to 96% with our standard 40 μm filter.<br />
This is an obvious benefit for ship owners with long periods<br />
between ballast water tank cleaning and compliments the very high<br />
performance of organic matter removal obtained by our BSF-series<br />
