Description
1.1, reverse osmosis equipment technology introduction
Reverse osmosis technology is the most advanced and most energy
efficient membrane separation technology. Its principle is above
solution under the action of osmotic pressure, based on other
material can't through the semipermeable membrane and the substance
and water to leave. Due to the reverse osmosis membrane membrane
pore size is very small (only for about *0 a), so can effectively
remove salt dissolved in water, colloid, microorganisms, such as
organic matter (removal rate as high as *7% - *8%). Reverse osmosis
is the high pure water equipment the most used one kind of
desalting technology, its separation object is solution of ion
range and molecular weight of hundreds of organic matter; Reverse
osmosis (RO) and ultrafiltration (UF), microporous membrane filter
(MF) and electrodialysis (EDI) technology belong to the membrane
separation technology. Nearly *0 years, reverse osmosis and
electrodialysis, ultrafiltration and membrane filtration has
entered the industrial application, mainly used in electronic,
chemical, food, pharmaceutical and drinking pure water, etc.
1.2, reverse osmosis equipment, reverse osmosis pure water
equipment principle of work
A. reverse osmosis equipment and osmotic pressure
Reverse osmosis equipment phenomenon in nature is a common, such as
a cucumber into the salt water, cucumber could because of water
loss and smaller. The cucumber water molecules into the brine
solution process is the process of osmosis. If you use a water
molecule can only through the film will be a pool partition into
two parts, the diaphragm on both sides were injected water and
brine to the same height. Over a period of time can be found to
reduce the water level, and saltwater level increased. We put the
water molecules through the diaphragm migration to the brine
phenomenon called osmosis phenomenon. Salt water level rise is not
open-ended, to a certain height will achieve a balance point. When
the diaphragm ends level difference represents pressure is called
the osmotic pressure. The size of the osmotic pressure and the
concentration of brine is directly related to.
B. reverse osmosis phenomenon and reverse osmosis water
purification technology
In the above device to achieve balance, if in the brine end head
put some pressure, at this time, water molecules will end by salt
water to pure water end migration. Fluid molecules in under the
action of pressure by dilute solution to the concentrated solution
migration process this phenomenon is called reverse osmosis
phenomenon. If the brine to join more than one end of the
facilities, and in the end put more than the brine osmotic
pressure, we can at the other end to get pure water. This is the
principle of reverse osmosis water purification.
Reverse osmosis pure water equipment production key has two, one is
a selective membrane, we call it a semipermeable membrane, 2 it is
to a certain pressure. Say simply, reverse osmosis semipermeable
membrane has many hole, the hole size and the size of the water
molecule is, due to bacteria, viruses, most of the organic
pollutants and hydrated ion are better than those of water
molecules, which can't through reverse osmosis semipermeable
membrane and reverse osmosis membrane through the water phase
separation. Many kinds of impurities in water, soluble salts is the
most difficult of the clear. Therefore, often based on desalination
rate level to determine the effect of reverse osmosis pure water.
Reverse osmosis desalination rate is mainly dependent on the
discretion of the reverse osmosis semipermeable membrane
selectivity. At present, high selective reverse osmosis membrane
element desalination rate can be as high as *9.7% (conductivity
acuities *0 μ s.c m).
1.3, reverse osmosis equipment process:
Raw water (water), booster pump, many medium filter (quartz sand
(**4 orders / **6 orders)/manganese sand/SS filter material),
activated carbon filter (coconut shell carbon/fruit shell
carbon/coal carbon) - softener (optional device) - level 1 reverse
osmosis host, level 2 reverse osmosis host - reverse osmosis
cleaning device, uv sterilizer, precision filter, water point
(conductivity acuities 5 μ s.c m).
