Reverse osmosis water treatment unit
1. Introduction:
Reverse osmosis water treatment unit is a membrane-technology filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.
2. Stages of reverse osmosis water treatment unit
1). Sediment Stage: Removes rough particles, sand and rust.
2). Quartz sand stage: Lower the turbidity of feed water (NTU)and sludge density index (SDI) values
3). Carbon stage: Removes chlorine and chemicals which would otherwise damage the membrane.
4). Resin stage: Purolite ion-exchange.
5). Reverse osmosis stage: Removes dissolved solids and all that are bigger than water molecule.
6. )Final Carbon stage: To improve the taste
7). Ozone sterilization: To kill microorganisms.
8). Storage tank
9. )UV sterilization: To kill microorganisms.
3. Advantage of reverse osmosis water treatment unit
1). Can production water continuously and highly automatic
2). No need the chemical regeneration, easy operation
3). RO system choose the import USA DOW membrane
4). Automatic switch on when low water level, and switch off when high water level
5). RO membrane can backwash automatic and reduce thepollution.
6). Water shortage protection for multi-stage pump
7). Porduction water condutivity meter can test the monitoring quality on line contionuosly.
8). Low operation Cost and Long life span
9). Easily control and Maintained.
10). Auto membrane flushing

9.FAQ(help you to know more)
Q: What is Reverse Osmosis
A: Reverse osmosis (R/O) is a water treatment process in which water is forced through a
semipermeable membrane that has very small holes or "pores". Clean water passes through and
impurities that are too big to pass through the membrane are left behind and flushed away.
Q: How Does Reverse Osmosis Work?
A: Reverse osmosis systems purify water by forcing pressurized water through a very fine, plastic
membrane. If the raw water being treated comes from a well or another private source, disinfection
and prefilters (to remove chlorine and/or particulates/sediment) may be needed in advance of the
R/O unit to remove contaminants that can foul or damage the membrane.
Q: How Do I Know What Size Unit to Buy?
A: R/O units are rated according to the amount of treated water produced per day. For example,
one type of unit produces 5000 liters of treated water per day under its design conditions. In reality,
conditions frequently vary. Line pressure is often lower, water will frequently be colder than 25° C and backpressure in the storage tank will likely reduce the performance of the unit. Consequently, you should examine water conditions and buy a larger rated unit than needed if any of the above problems are noted.
Q: Material of reverse osmosis system?
A: You can choose FRP filter + U-PVC pipe, stainless steel filter + U-PVC pipe or total stainless steel
Q: What is packing of this machine? Is it suitable for shipment?
A: Machine will be packed by standard wooden case. It is suitable for shipment. After you
receive machine, you only need to open wooden case to pick up machine.
Q: Is this machine easy to install? Will you arrange engineer to help me install?
A: This machine is very easy for install. The machine you received is assembled. You will only
need to put material inside to filters, and then backwash, fast rinse filters. It is very easy for you
to follow our English instruction and video.
Q: How can I pay you?
A: After we confirmed order, I will send you contract sales with our company bank information.
You can transfer money to our company bank account by T/T.
