Each reverse osmosis membrane element is made from a reverse osmosis membrane flat sheet. There are several manufacturers of RO membrane flat sheets in the world. The largest are DOW Chemical, GE, Toray, and Hydranautics. Each brand offers RO membrane flat sheets with unique specifications. The chemical composition of each RO membrane is protected by patents and remains a well-guarded secret. Reverse osmosis membrane flat sheets are usually classified by porosity, flow rate, and salt rejection under given feed water concentration, temperature, and pressure. High-quality RO membrane housings are also important in the production of the RO membrane.

Water desalination can be performed by using reverse osmosis water treatment systems. This is the most economical way for desalination of sea and brackish water today. AXEON Water Technologies designs, engineers and manufactures a variety of reverse osmosis water treatment systems. The main component of reverse osmosis water treatment systems is the reverse osmosis membrane. To protect the reverse osmosis system from dangerous impurities contained in feed water, the system is equipped with the appropriate pretreatment components, such as sediment filters and anti-scalant dosing systems. After the reverse osmosis membrane, the product water usually has a low pH. To adjust the pH, the water passes through a pH adjustment stage in the system. Then the treated water goes into a storage tank. The last stage consists of disinfecting, re-pressurizing and distributing the water for use.

Sea Water Reverse Osmosis Systems: Axeon’s Available Commercial Reverse Osmosis Systems for Desalination
World consumption of water doubles every 20 years, which is more than double the rate of population growth. According to the forecast, for the year 2025, the demand will exceed the resources by 56%. This will result in a permanent drought in some areas, population movements in coastal cities and an increasing demand for water in industry. Fresh water resources are diminishing while water consumption in industry and other human needs is increasing. The lack of fresh water slows economic development and reduces the quality of life. An urgent global need for more effective management of this valuable resource is obvious. AXEON Water Technologies has developed reverse osmosis machines to produce abundant fresh water from seawater and complex sources of brackish water. A reliable reverse osmosis machine, in other words, can mean the difference between scarcity and sufficiency.

Reverse osmosis water filter systems are used widely in households across America. Among other things, reverse osmosis filter systems allow a household to meet EPA water standards. When the TDS of the feed water is too high, using reverse osmosis membranes is the best choice for a homeowner to get quality drinking water. There are few different choices of reverse osmosis water filter systems that can be used in households.

Reverse osmosis water filters remove the large majority of minerals in the water. The low level mineral concentration in water produced by reverse osmosis filtration systems is a major point of controversy. However valid the point may be that the human body requires salts, calcium, magnesium and other minerals found in unpurified water, the body does not need the contaminants and microbes that are also found there. It can be argued that although water that has passed through a reverse osmosis filter is lacking in healthy minerals, it is also purified of dangerous substances and toxins. It is not recommended that a person drink contaminated water just to acquire necessary minerals and salts that are not found in water from a reverse osmosis filtration system. These things can be obtained through a healthy diet. Calcium, for example, is better acquired through a glass of milk.

These reverse osmosis membranes are designed specifically for use in the household with under-the-sink reverse osmosis systems. These reverse osmosis systems have all the important steps of filtration before the reverse osmosis membrane and after the reverse osmosis membrane. The reverse osmosis membrane is usually the most expensive consumable part of the reverse osmosis system and needs to be protected by inexpensive sediment and carbon filters. The sediment filter provides protection for the RO membrane by reducing the amount of particles in the feed water and reduces the risk of erosion on the membrane in reverse osmosis systems. The micron rating of the sediment filter can be 50, 25, 20, 10, 5 or 1 micron. With durable RO membrane housing, you can ensure that these filters and the membrane itself are not compromised by external factors.
