3000L/H Pure Water Reverse Osmosis System Suitable For Chemical
Plants
I.Osmosis Principle
A membrane that is selective in the substances it allows to pass
through is called a semipermeable membrane. A membrane that is
permeable only to the solvent but not the solute is generally
called an ideal semipermeable membrane. When equal volumes of a
dilute solution (e.g., fresh water) and a concentrated solution
(e.g., salt water) are placed on either side of a semipermeable
membrane, the solvent in the dilute solution will naturally pass
through the membrane and flow toward the concentrated solution.
This phenomenon is called osmosis.
II.Reverse osmosis principle
When osmosis reaches equilibrium, the liquid level on the
concentrated solution side will be higher than the dilute solution
by a certain amount, creating a pressure differential known as the
osmotic pressure. The magnitude of this pressure depends on the
inherent properties of the solution. If a pressure greater than the
osmotic pressure is applied to the concentrated solution side, the
solvent will reverse its original osmotic direction, flowing from
the concentrated solution toward the dilute solution. This process
is called reverse osmosis.
III.Function:
●Water filtration
●RO membranes auto wash and manual wash
●Auto stop on high pure water level, auto start on low pure water
level
●Multi-phased pump can prevent the system from water shortage
●Protection of power-off, under voltage, excessive current, short
circuit, leakage of electricity.
FAQ
1. Q: Which machine should I choose?
A: It depends on your raw water quality and your requirements for
permeate water.
Usually there are three parts: pretreatment, RO machine, and post
treatment. Pretreatment could be UF(ultra filtration)
system,anti-scale dosing system, flocculant dosing system,
disinfectant dosing system, water softener, sand filter, carbon
filter,security filter etc. Post treatment could be UV sterilizer,
Ozonizer, ClO2 sterilizer, etc. And maybe you need an EDI system.
We will choose proper process according to your raw water quality
and permeate water purpose.
2. Q: What’s your machine material?
A: For pretreatment tanks, we usually use FRP or S.S. The RO frame
could be S.S, carbon steel.For pipes, it is usually S.S and UPVC.
We can choose material according to your special requirements.
3. Q: What’s the control method?
A: For pretreatment, you can choose manual or automatic; for the
whole system, we use relay, PLC or man-machine interface remote
controld
4. Q: Which spare parts need to change regularly?
A: Filter cartridge in the security filter and RO membranes. For
filter cartridge, it needs to change each 3-6 months, and for RO
membrane, you need to change each 1-3 years. It depends on your
water quality and how you maintain the machine.
5. Q: What’s your warranty?
A: Our warranty is 1 year. But to our experience, our machine can
work 5 years before repair.
6. Q: What’s your electricity requirement?
A: Our machine could be 380V/220V/110V, 50HZ/60HZ, 3 phase/single
phase. We can do customer made products.
7. Q: What’s your machine size?
A: It depends on the capacity requirement and we can make changes
according to your space.
8. Q: What’s your membrane brand?
A: We have all kind of brand , As guest request .
9. Q: What’s the purchase procedure?
A:Customer send Inquiry -----we provide solution and
quotation-----customer confirm and place order-----we send
PI-----customer make first payment----we arrange
