The filter material of the multi-media filter should have
sufficient chemical stability. The relative density and particle
size of each medium should be different. The relative density of
anthracite used in the double-layer filter filter composed of
anthracite and quartz sand is 1.4. -1.6, particle size is
0.8-1.8mm, quartz sand relative density is 2.6-2.65, particle size
is 0.5-1.2mm; 3-layer filter filter can use manganese sand,
magnetite in addition to the above two kinds of filter materials
Such heavy ore has a relative density of 4.7-5.0 and a particle
size of 0.5-4 mm.
Multi-Media filters are designed for enhanced water quality
filtration for the removal of organic and inorganic suspended
solids down to 5 microns.
Multi-Media filters may be used as a stand-alone system or in
conjunction with or as a pretreatment for other filtration
technologies.
The Multi-Media Filtration Systems utilize a vertical side shell
depth of 60" with accompanied reverse stacked medias for
progressive filtration through the filtration system.
Industrial media filters utilize our simple backwash system for
ease of
operation and consistent water quality.
Application
Removal of organic and/or inorganic suspended solids down
to 5 microns with enhanced solids capacity vs. single media
sand filtration
■ Storm water runoff, industrial process water, incoming plant
water, waste water clean-up, industrial water for plant reuse
■ Pre-filtration in applications such as granular activated carbon,
reverse osmosis, cartridge or bag filtration and deionized water
■ 80 psi standard operating pressure (high pressure systems
available)
■ Flow ranges from 10 gpm
Advantages
State of the art fabrication provides added strength under pressure
and long system life
■ ASME code shaped head construction for durability and safety
■ Stainless steel wedgewire underdrain
➤ Ensures structural integrity in the harshest conditions
➤ Hydraulically balanced to increase effectiveness of backwash
while reducing flush frequency and waste of water
➤ High strength stainless steel wedgewire will withstand a collapse
pressure in excess of 600 psi
■ Standard carbon steel products, 3/16" thick material
■ Backwash automatically initiated by elapsed time or pressure
differential
