6.9.1
Iron and Manganese Removal. Refer to Recommended
Standards for Water Works , Part 4.5, Health Education Services,
1997 edition; and Water Quality and Treatment , Chapter 10,
"Chemical Precipitation," AWWA, fourth edition.
6.9.2.
Taste and Odor Control . Several treatment processes
can control taste and odor. These processes include; copper
sulfate treatment, aeration, activated carbon, chlorine dioxide,
and ozone. For guidelines regarding these treatment processes
refer to Recommended Standards for Water Works, Part 4.9, Health
Education Services, 1997 edition; Water Quality and Treatment,
AWWA; and AWWA Standards B600, Powdered Activated Carbon; B601,
Sodium Metabisulfite ; B602, Copper Sulfate; B603, Potassium
Permanganate ; and B604, Granular Activated Carbon, AWWA.
6.9.3
Corrosion and Scale Control . Refer to Water Quality
and Treatment, Chapter 17, Internal Corrosion and Deposition
Control , AWWA, fourth edition; and AWWA Scale and Corrosion
Control Standards B501 through B505, B510 through B512, and
B550.
6.9.4
Fluoridation . Refer to Recommended Standards for
Water Works, Part 4.7, Fluoridation , Health Education Services,
1997 edition; Water Quality and Treatment, Chapter 15, "Water
Fluoridation," AWWA, fourth edition; and AWWA Standards B701,
Sodium Fluoride; B702, Sodium Fluorosilicate; and B703,
Fluorosilicic Acid, AWWA.
6.9.4.1
Standby . It is not necessary to provide standby
equipment for fluoride addition or removal since a short-term
interruption in treatment for repairs and maintenance is not
considered detrimental to the long-range effects of this type of
treatment.
6.9.5
Reverse Osmosis Treatment . Reverse Osmosis can be
used for the removal of all of the inorganic compounds listed in
40 Code of Federal Regulations (CFR) Part 141 through 143.
Treatment units are typically sized after conducting pilot
studies, particularly when units are being used for the removal
for specific inorganics. Brine solutions produced during
treatment can be discharged to a sanitary sewer, to a brine
evaporation pond, or in some cases to a watercourse such as a
