The success of the installation will depend, to a great
extent, on advanced planning and preparation. Careful
attention to the location of the unit, accessibility to
electrical and drain facilities, and the availability of the
proper tools will ensure a professional-looking installation.
Of utmost importance is the assurance that the filter has
been properly applied and meets all specifications.
APPLICATION:
Correct application is directly associated with the
performance and life expectancy of any water filter. It is
important, therefore, to understand how your Brita
®
Pro
Water Filter functions and to know its capabilities and
limitations so that a correct application can be made.
By following the guidelines and recommendations set forth
in this manual, you can be certain your filter is applied
correctly.
MM / NEXSAND FILTER
The Automatic Water Filter is capable of removing
particulate matter particle size as small as 30 microns.
It will not remove color, organics, colloidal turbidity or
dissolved solids. Some applications include:
- Removal of suspended matter in any water system
- Removal of particulate matter, such as clay, mud, etc.
- Prefiltration of oxidized iron prior to an automatic or
manual softener
-Removal of light sand
The quality and number of gallons of filtered water
between backwashes will depend upon the amount, type,
and size of the particulate matter being filtered. If a water
sample is sent to a laboratory, where application of a MMF
Type unit is contemplated. The laboratory will test for
Nephelometric Turbidity Units (NTU) and suspended solids
(mg/L). The sample will also be filtered through 10 micron
filter paper and NTU run on a filtered sample. If the NTU
of the raw water exceeds 150, suspended solids exceed
150 mg/L, or the filter water through the 10 micron filter
paper has unacceptable quality, a MMF filter might not
be applicable. As a guide, the U.S. Public Health Drinking
Water standards states the turbidity should not exceed
1 NTU. The exact number of gallons filtered between
backwashes can not be given because of many variables.
TO FILTER
Automatic Water Filter with Activated Media will control
chlorine taste and odor, and it will also remove most
objectional organic colors. It will not remove hydrogen
sulfide. It is important to note that whenever the cause
of an objectional taste or odor has not been established,
Health Authorities should determine if the water is safe
to drink. Do not use with water that is microbiologically
unsafe or of unknown quality without adequate disinfection
before or after the system.
NU FILTER*
Automatic Water Filter with Neutralizing Media will
neutralize slightly acid water (pH 5.2 to >6.8) and thus help
to prevent unsightly brown or green stains due to corrosion
of household plumbing. If the pH is between 5 and 6, one
part of Magnesium Oxide Media should be mixed with five
parts of Calcite Media to provide additional neutralizing
capability. If the water to be treated has a pH less than 5, a
high hardness, or a high carbon dioxide level, NF might not
be applicable; a solution feeder should be used. Because
NF adds hardness, it should be used prior to a softener.
BM FILTER
This media acts as a catalyst for the removal of iron and
manganese from the water but require pre-oxidation. This
media removes the iron and manganese from the water.
This is not recommended to remove hydrogen sulfide from
the water and requires high pH water. The media is not
sacrificial hence no replenishment is required.
BASICS
NOTE
Under dynamic conditions it might be necessary to mix five parts
Calcite with one part Magnesium Oxide to effectively raise the pH.
In order to size and apply the equipment correctly, a complete
analysis of the water supply should be obtained.
