Reverse Osmosis Water System Pure Water Treatment Equipment

Description

It is applied for the production of pure water, beverage's product water and process water. It is mainly composed of the following equipments: Pre-treatment system (multi-medium filter, active carbon filter, ion exchanger, Millipore filter), membrane separation system (Ultrafilter, nanometer filter, RO system), electrodialysis device, sterilization system (UV device, ozone device) and so on.

1. Automatic reverse osmosis
2. Hydranautics membrane
3. Stainless steel frame
4. Capacity: 250L-1000

What is Reverse Osmosis?
Reverse osmosis (R/O) 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.

Do I Need a Reverse Osmosis Unit?

It is presumed in this document that the water you are using meets all health regulations and is known to be safe. If your municipality or utility supplies your drinking water, it is likely that you do not need a reverse osmosis unit. Municipally supplied drinking water is microbiologically safe. It is treated to meet health and aesthetic requirements, and is subject to routine testing for microbiological contamination.

How Does Reverse Osmosis Work?

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 pre-filters (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.

Stages of reverse osmosis:
During the initial filtration stage, tap water or well water (pressurized by a booster pump) is passed through a particle filter (a pre-filter) that removes silt, sediment, sand, and clay particles that might clog the R/O membrane.
The water is then forced through an activated carbon filter that traps minerals and contaminants such as chromium, mercury, copper, chloramine and pesticides. It also removes chlorine, which is important, as chlorine will shorten the life of the membrane.

Water is transferred under pressure into the R/O module, allowing only clean water to pass through the small pores in the membrane. Impurities unable to pass through the membrane are left behind and flushed down the drain.

Treated water is then sent to a storage tank.
Treated water is passed through an activated carbon filter before use to further improve the water's taste and smell.
Water that contains manganese, hydrogen sulphide or iron should be pre-treated to extend the life of the membrane. A dealer can recommend the pre-treatment needed.
