Introduction of NSF Standard for water treatment
NSF/ANSI Standard 42:
飲用淨水系統–
美感效果
概要:
消除水中的氯, 臭味,
臭氣和微粒狀物質等對健康有害的污染物質。
NSF/ANSI
Standard 42:
Drinking Water Treatment Units - Aesthetic Effects
Overview: This standard covers point-of-use (POU) and point-of-entry (POE)
systems designed to reduce specific aesthetic or non-health-related
contaminants (chlorine, taste and odor, and particulates) that may be
present in public or private drinking water.
NSF/ANSI
Standard 53:
飲用淨水系統–
健康效果
概要:
設計為有效去除水中對健康有影響的污染物, 如綜合化學污染物, 鉛等重金屬, 蘭布爾吉亞爾氏鞭毛虫,隱孢子蟲,甲基第三丁基醚等等。
NSF/ANSI Standard 53:
Drinking Water Treatment Units - Health Effects
Overview: Standard 53 addresses point-of-use (POU) and point-of-entry
(POE) systems designed to reduce specific health-related contaminants,
such as
Cryptosporidium,
Giardia,
lead, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl
ether), that may be present in public or private drinking water.
NSF/ANSI Standard 58:
逆流滲透系統
概要:
減少比較普遍的污染物如氟化物和鉻等重金屬,
含鹽度, 硝酸鹽等等。
NSF/ANSI Standard 58:
Reverse Osmosis Drinking Water Treatment Systems
Overview: This standard was developed for point-of-use (POU) reverse
osmosis (RO) treatment systems. These systems typically consist of a
pre-filter, RO membrane, and post-filter. Standard 58 includes contaminant
reduction claims commonly treated using RO, including fluoride, hexavalent
and trivalent chromium, total dissolved solids, nitrates, etc. that may be
present in public or private drinking water.
NSF/ANSI Standard 44:
陽離子交換軟水系統
概要:
減低水的硬度。
同時也能減少水中的鐳與鋇。
NSF/ANSI Standard 44:
Cation Exchange Water Softeners
Overview: This standard covers residential cation exchange water softeners
designed to reduce hardness from public or private water supplies.
Additionally, this standard can verify the system's ability to reduce
radium and barium.
NSF/ANSI Standard 55:
紫外輻射殺菌系統
概要:
系統分成兩個等級。 A 等級(40000uwsec/cm2)設計為消毒,
殺菌或過濾微生物, 包括病毒。B等級 (16,000
uwsec/cm2)設計為殺菌以達到地方人民的基本健康。
NSF/ANSI Standard 55:
Ultraviolet Microbiological Water Treatment Systems
Overview: This standard establishes requirements for point-of-use (POU)
and point-of-entry (POE) ultraviolet systems and includes two optional
classifications. Class A systems (40,000 uwsec/cm2) are designed to
disinfect and/or remove microorganisms from contaminated water, including
bacteria and viruses, to a safe level. Class B systems (16,000 uw-sec/cm2)
are designed for supplemental bactericidal treatment of public drinking
water or other drinking water, which has been deemed acceptable by a local
health agency.
NSF/ANSI Standard 62:
蒸餾系統
概要:
設計為減少水中特殊污染物, 包括砷,
鉻, 水銀, 硝酸和微生物等等。
NSF/ANSI Standard 62:
Drinking Water Distillation Systems
Overview: Standard 62 covers distillation systems designed to reduce
specific contaminants, including total arsenic, chromium, mercury,
nitrate/nitrite, and microorganisms from public and private water
supplies.
NSF/ANSI Standard 177:
花灑沐浴系統
–
美感效果
概要:
設計為減少水中的氯。
NSF/ANSI Standard 177:
Shower Filtration Systems - Aesthetic Effects
Overview: This standard covers point-of-use (POU) shower filtration
systems, designed to reduce free available chlorine that may be present in
potable water (public or private).
