1, Salt water purifier Quartz sand filter
Quartz sand filter mainly removes suspended solids, colloids,
sediment, clay, rot plants, particulate matter and other impurities
in water, reduces
the turbidity of water, and achieves the purpose of water quality
clarification. After treatment, the water pollution index SDI≤4 can
prevent
membrane Surface fouling (including CaCO3, CaSO4, SrSO4, CaF2,
SiO2, iron-aluminum oxide, etc.), prevention of fouling of
colloidal
substances and suspended solid particles, prevention of fouling of
organic substances and microorganisms, and protection of reverse
osmosis
membranes.
2, Salt water purifier Activated carbon filter
Activated carbon filter mainly uses activated carbon to have a
large number of functional groups such as hydroxyl and carboxyl
groups, which
can chemically adsorb substances of various natures to remove odor,
organic matter, colloid, iron and residual chlorine in water, and
reduce
the color and turbidity of water. , reduce pollution to reverse
osmosis, residual chlorine after treatment ≤ 0.1ppm
3. Salt water purifier Softening device
The sodium ion on the ion exchange resin exchanges calcium and
magnesium ions in the water to reduce the hardness in the water
while
regenerating the ion exchange resin with the salt.
4, Salt water purifier Security filter
The 5 micron polypropylene wound fiber filter is used as the filter
element, mainly to remove the particles of more than 5 micrometers
that have
not been removed by the pretreatment system, and to remove the
filter material lost before the treatment, thereby protecting the
RO membrane
from being less polluted. Whether the filter element can reach
normal use conditions will affect the normal working conditions of
the membrane.
5, Salt water purifier Reverse osmosis system
Including high pressure pumps, reverse osmosis membranes, membrane
shells, cleaning systems and related piping, valves, measuring
instruments, etc. The reverse osmosis membrane adopts the ULP
series ultra-low pressure composite membrane element which is
imported
from American Dow Company. The first-stage desalination rate is
above 99%, and the reverse osmosis water conductivity is less than
15μS/cm.
The reverse osmosis membrane element is compounded by a three-layer
membrane, the surface layer is made of aromatic polyamine, and has
a thickness of about 2000 angstroms and is supported by a layer of
microporous polysulfone layer, which is resistant to mechanical
tension and
chemical attack. The assembly has a large membrane area of 370
feet and a relatively large water production flux.
