HOW THEY WORK

WBC 170SC-2

WBC 90SC-2

Up-flow Design

Air is automatically purged due to principle of up-flow filtration.
Filtered liquid exits the filter at the highest point. A secure lifting
handle prevents cross contamination of filtered and unfiltered
liquid. This patented up-flow design allows Harmsco® to utilize
100% of cartridge surface area, providing efficient filtration. Filter
efficiencies are dramatically improved to provide longer filter
runs and reduced filtration costs. Harmsco® Hurricane® filter
cartridges for the WBC filters are available in a wide range of micron
ratings and may be cleaned and re-used in most applications and
micron ratings.

Sizing

Use the chart shown below to size WBC Filters for your application:

*Parallel installation with valves to isolate filters for service while other filters are operational.
Note: Lower flow rates and pressures result in longer cartridge life. Designing to 70-80% of maximum flow will increase overall performance.

Pressure Drop

The total head loss data shown below was developed by NSF International and indicates pressure drop with

Cartridge Cleaning Instructions

Hurricane® cartridges are made of Polyester Plus™,
a proprietary blend of polyester fibers which can be
cleaned in most applications and micron ratings to
make Waterbetter

®

filter elements reusable! For best

results, follow the directions described below:

When Cartridge Cleaning
is Possible

Clean cartridge when pressure differential is 12 psi
above startup differential.

Non-cleanable Applications

Replace cartridge when pressure differential is 30 psi
above start-up differential or when flow has diminished
to an unacceptable level, indicating cartridge is at
capacity.

Cartridge Removal

To remove filter cartridge, drain filter housing. Remove
lid. Hold lifting handle and pull upward to remove filter
cartridge from filter housing. Follow cleaning
instructions described herein.

Lid Replacement

Clean o-ring and contacting surfaces of tank and lid.
Reposition o-ring, lid and clamp band making sure that
clamp covers housing flange and lid flange. Tighten
clamp band slowly insuring proper engagement of
clamp to flanges. Continue tightening clamp closure
bolt and, if necessary, strike the clamp with a mallet in
an inward radial direction and all around its circumfer­ence to prevent sticking between clamp and flanges.

When Cartridge Cleaning is Not Possible

For best results, clean
cartridges with pressure
nozzle using standard
hose. Direct spray at
an angle to remove
particulate (see photo).
Follow these directions
to remove oils, organic
matter, algae and mineral
deposits.

OILS: Soak cartridge in
a solution of tri-sodium
phosphate or similar
strong detergent (2 lbs. to
10 gallons of water). Soak
up to 12 hours for best
results. Rinse after bath.

ORGANIC MATTER, ALGAE: Use tri-sodium phosphate solution
as described above, plus 1 pint of liquid chlorine to kill organic matter
and algae. Soak cartridge one hour or longer until surface is no
longer “slippery.” Rinse after bath.

CALCIUM MINERAL DEPOSITS: Follow directions for “oils”
described above. Soak cartridge for approximately ten minutes in a
solution of one part of muriatic acid to twenty parts of water. Rinse
cartridge thoroughly with water.

Generally, it is not possible to clean Hurricane

®

filter cartridges when
filtering petroleum-base liquids, toxic substances, and one and
below micron applications.

Note: Pressure gauges are recommended to indicate when cartridge
cleaning or replacement is necessary.

Cartridge Care

Cartridge Cleaning in Aqueous Applications

Caution: Do not rinse cartridges with acid
until oils and organic matter are removed.
Use detergent first and follow with acid bath
for mineral removal. Flush cartridges with water
after muriatic or tri-sodium phosphate baths.
