BASIC PRINCIPLES
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 WaterGroup 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 / nextSand 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 dissoved 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 throught 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.
*
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.
