Filtration
Systems featuring engineered filtration media such as Macrolite® provide
outstanding backwash filter performance. In addition to custom media,
standard configurations using carbon or calcite are also available.
Macrolite®
Macrolite,
a processed mineral oxide manufactured exclusively
by Kinetico, is used as a highly efficient filter media for the
removal of oxidized iron and suspended matter. 40-60 mesh
ceramic media has a tremendous loading capacity and an
extremely fast cleanup time when backwashing at 6-7 gpm/ft2.
This ceramic media is chemically inert and is not affected by acids
and bases. Tests have shown that its attrition rate is nearly zero.
This media typically removes suspended solids down to the
5 micron range.
Carbon
Carbon is used for the removal of taste, odor and color. Granular activated
carbon used in Kinetico equipment is an excellent filtration medium with
efficient adsorption characteristics. The most common application is the
removal of chlorine from the water supply. Activated carbon requires only
periodic backwashing to eliminate accumulated suspended matter and re-grade
the filter bed. When the filter bed loses the capacity for chlorine, the bed
must be replaced. If the unit is used in conjunction with a chlorine feed
system for the removal of oxidized iron, the unit should be set to backwash
1-2 times per week of operation.
Calcite
A crushed and screened white marble material, calcium carbonate is used to
neutralize acidic or low pH waters. Calcite, on contact with acidic waters,
slowly dissolves the calcium carbonate media to raise the pH. This
effectively neutralizes the water and reduces the potential corrosion of
copper and other metals found in plumbing systems. Periodic backwashing is
necessary to maintain high service flow rates and prevent packing the filter
bed. Since calcite dissolves, it must be replaced. The frequency depends on
the pH and water demands. As calcite neutralizes the water, it will increase
the water’s hardness, and a softener may need to be added after the filter.
Disc selection is partially dependent upon the amount of water being used on
a daily basis
Filter Ag
Filter Ag is a non-hydrous aluminum silicate which can be used as a highly
efficient filter media for the removal of suspended material. Filter Ag
granules have irregular surface characteristics for the maximum removal of
suspended matter through the filter bed. Filter Ag typically removes normal
suspended solids, down to the 20-40 micron range. The disc selection here is
totally dependent on the amount of suspended solids in the water. Higher
amounts of suspended solids will require a more frequent backwash.
