CHUNKE pressure filters can be used in a variety of service conditions
including, but not limited to: industrial, municipal, and
institutional applications. CHUNKE’s pressure filters clarify water
by removing sediment, turbidity, iron, unpleasant tastes and odors,
suspended particles, and unwanted color, all of which are commonly
found in surface water. CHUNKE supplies a full line of standard and
fully customizable water filtration systems, all of which are
engineered using advanced 3D computer modeling software for accurate and customized solutions.
Filter Media Types:
o Sand is the most common filter media. Generally, fine mesh sand is coupled with a course grain support bed
to remove suspended solids and turbidity. Graded in various ranges,
CHUNKE sand can be used as filtration medium or underbedding depending on
particle size and application.
o Gravel has a highly spherical shape that promotes good flow and even
distribution in support beds.
o Calcite media is specially graded calcium carbonate compound for
neutralizing acid with consistent dissolving rates for water
treatment.
o Manganese Greensand media is treated siliceous material for treating water containing
iron, manganese and hydrogen sulfide through oxidation.
o Anthracite is recommended as a filter medium where additional silica in the
water is not desirable and can remove lighter weight turbidity.
Anthracite is typically used in applications where silica pick-up
is undesireable.
o Activated carbon medium is used to remove taste, odor, organic contaminants, and
chlorine as well as being used in many drinking water applications.
o ProSand is based on a rare natural mineral. Its unique properties radically
improve the performance and cost of media filtration.
o Multimedia is required when maximum quality water is required and unwanted
sediment is too small to be removed by standard media. It consists
of multiple layers of increasing grain size to remove sediment as
small as 10 microns.
Advantages of Multimedia Filtration
o Relatively inexpensive, no recurring cost of consumables
o Proven process and most tested forms of water treatment
o Systems are robust with no moving parts inside the tanks
o Modular control valves designed for operational flexibility
o Filtration media is inexpensive and long-lasting
o Easily cleaned and maintained
o Resistant to fouling (clogging)
