The FAQ of pure water treatment machine
Q1: How often the pure water treatment machine should be washed?
A1: Generally, when the standardized flux decrease 10%~15%, or the
system desalinization rate decrease 10%~15%, or the operation
pressure or section pressure differences increase 10%~15%, the pure
water treatment machine should be washed. Washing times is related
to system preprocessing, when SDI15<3, the washing frequency is
around 4 times/year; when the SDI15 is around 5, may be the washing
frequency is 1 times than SDI15<3, but the washing frequency is
also depend on the actual situation.
Q2: What is SDI?
A2: It is used to evaluate the colloid contamination possibility of
RO system.
Q3: Which should be choice between RO treatment and ion exchanger
treatment in general situation?
A3: Both RO treatment and ion exchanger treatment can be adopted.
Base on economic conditions, generally, if the saltness is highre,
the RO treatment is much substantial. If the saltness is lower, the
ion exchanger is much substantial. Now, because the RO technology
is widespread, more and more people adopt RO treatment+ion
exchanger.
Q4: How long dose one RO membrane can be used?
A4: Generally, one membrane can be used for 5 years. On the other
hand, the membrane life time is depend on the chemical stability of
membrane, physical stability of components, cleanable, raw water
source, preprocessing, washing frequency, operation and management
and so on.
Q5: How about the membrane separation ability?
A5: RO technology is the most precision liquid filter technology.
RO membrane can intercept inorganic molecule and molecule that
dimension larger than 100. On the other hand, hydrone can permeate
membrane freely.
Q6: What is the Max. silicon dioxide concentration can be allowed
in raw water?
A6: The Max. silicon dioxide concentration is depend on
temperature, PH and antisludging agent. When the antisludging agent
isn't add, the Max. is 100ppm on concentration water side.
Q7: What kind of preform need before water flow into RO?
A7: The particle and suspended solids can be avoided through sand
filter, carbon filter, ion exchanger, and precision filter. In
order to the particle damage the HP pump blade and membrane
components.
Q8: Could the membrane avoid virus and germ?
A8: The membrane has very high removal rate, at least 3log. Of
course, the other components, detection and maintenance way are
also importance steps, it can't depend on RO membrane completely.
Q9: Could temperature influence water yield?
A9: The temperature is higher, the water yield is more, vice versa;
when the temperature become higher, the pressure should be turn
down, vice versa.
Reverse osmosis is a kind of reverse migration movement, with the
aid of semipermeable membrane separate the solute and solvent under
pressure. Using RO technology to avoid inorganic ion, germ, virus,
organics, colloid and so on in raw water.
