3000L/H Industrial Reverse Osmosis System with PLC Control

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 production----customer make the rest payment-----we ship goods from our factory.
