How a Reverse Osmosis Membrane Works
Reverse osmosis systems work by using high pressure to force water through a semipermeable reverse osmosis membrane element.
RO membranes are made of a thick polyamide film that contains tiny pores through which water can flow. RO membrane element pore sizes can vary from 0.1 to 5,000 nanometers (nm) depending on application.
The pores in the RO membrane are small enough to restrict organic compounds such as minerals and salt but allow water molecules to pass through.
Reverse osmosis membranes are also porous and restrictive enough to filter out disease causing pathogens and bacteria from water.

Typically RO membranes have an estimated life expectancy of 2~3 years. Many factors determine an RO membrane's life expectancy, such as feed water quality and frequency of use. Methods for cleaning RO membranes are often not cost effective for residential RO systems
II. About Reverse Osmosis Membrane FoulingAll reverse osmosis membranes lose their performance and foul over time. Suspended solids, microorganisms, and and other particles build-up on the RO membrane surface and cause fouling. Examples of suspended solids often found in feed water include oil, silica, clay, iron, sulfur and acids. | Restaurants | Hotels | Humidification | Beverage |

I: Are you a trading company or a manufacturer?
A:We are RO membrane manufacture,have 20 years experience in water treatment filed
II: Can I get a sample? Can I place small order before bulk purchase?
A: We can provide one free sample,but customer need bear delivery fee
III: Working TDS?
Our RO element can work with 4000ppm feed water with good perforance,india south water quality 3000~4000ppm
VI: What membrane flatsheet do you use?
We use DOW FILMTEC sheet to make sure RO element stable performance
When customer has tight budgets,we choose domestic sheet with better stable performance
V: What's the difference Dupont sheet and Domestic sheet?
Dupont is famous,and price is higher than domestic sheet
Dupont sheet has more stable performance than domestic sheet
IV:What's your RO membrane element life?
Typically RO membranes have an estimated life expectancy of 2~3 years. Many factors determine an RO membrane's life expectancy, such as feed water quality and frequency of use
