Stainless Steel Full Automatic Secondary Reverse Osmosis and EDI Pure Water System

Stainless Steel Full Automatic Secondary reverse osmosis and EDI pure water system


1. What is reverse osmosis system/RO system?
RO water purifier system/ro water treatment system is one of the highest technology in modern pure water purification, raw water such as tap water, well water, borehole water, brackish water, sea water etc. Through the pretreatment then pass the reverse osmosis system, it can remove 97%colloid, solid, turbidity, chlorine, odor. The pure water completely in line with international standards for drinking water. It is a key of pure water treatment equipment.

2. The process of RO device

Raw water-- Raw water tank --Raw water pump --Quartz sand filter-- Active carbon filter-- Security filter-- high pressure pump-- RO systemPure water tank-- UV/Ozone --Pure Wate


1). Raw water pump-- provide the pressure to quartz sand filter/active carbon filter
2). Quartz filter-- get rid of turbidity, suspended matter, organic matter, colloid, etc.
3). Active Carbon filter--Remove the color, free chloride, organic matter, harmful matter, etc.
4). Water Softener--using ion exchange resin to exchange "ions" of calcium and magnesium is the most common and the easiest method of removing hardness of water and render the water suitable for utility purpose
5). Security filter--It is also called cartridge Filter, prevent any deposition of large Particles, most of the bacteria, and viruses into the UF membrane and RO membrane, The accuracy is 5um, for holding back any large particulates such as large iron, dust, suspended matter, impurity.
6). High pressure pump-- The high pressure pump is used for make sure there are enough water for satisfying designed production capacity.
7). RO (reverse osmosis) system--RO system is the main part of pure water treatment plant. The RO membrane's desalt rate can reach as high as 99%, it is capable of removing over 99% of ions, bacteria, particles and 98% of organic

Q: What is Reverse Osmosis(RO)?
A: Reverse osmosis (RO) is a water treatment process in which water is forced through a semi-permeable 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: 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 just need to put filter material into filters, connect electric power and feed water, and then backwash, fast rinse prefilters, at first time use, you have to flush RO membranes by regulating inlet water valve and dense water valve, we put labels with English name on every filters and valves and let you know what they are. It is very easy for you to follow our English instruction and video.

Q: If there are problems of machine, how can I solve?
A: You can contact me by e-mail or mobile or skype, and then tell me problems, send pictures. If it is in one year warranty time, I will send you spare parts for free. If it is more than 1 year, I will help you to find problems, and you can buy spare parts from me or in locally. 

Q: What is warranty
A: Our warranty is one year. If you have any problems in one year, just take photoes to show us. Our engineer team will help you to find problems. If any spare parts need to replace, we will send you new one for free.

Q: How can I pay you?
A: After we confirmed order, I will send you sales contract with our company bank information. You can transfer money to our company bank account by T/T. Or you can pay via Western Union or Alibaba Trade Assurance with credit card, Smartcard or Visa Card. Or do L/C if it is accepted by both of us .
