Reverse osmosis desalination plant, rich students, sewage treatment reverse osmosis desalination plant

RO reverse osmosis desalination systems and equipment is the rapid development of the late twentieth century up of membrane water treatment methods, it is brackish water, desalination plant, one of the most effective method for preparing the brine, pure water, high pure water in addition. It is the center of the reverse osmosis membrane technology, the membrane material is a special processing method and made of a thin film having semipermeable properties. It enables the selective solution of certain components in addition to the role by the pressure to achieve water desalination, purification purposes. The first appeared in 1960 in the world of asymmetric cellulose acetate membrane reverse osmosis membrane water making it possible to apply to the industry. Early the plate membrane, tubular membrane, in the sixties, the late emergence of the roll, hollow fiber membrane, the early seventies has developed a desalination membranes. In the five years between 1972-1977, increasing the number of reverse osmosis units worldwide 15 times, the capacity of water increased by 41 times, until after the eighties is still 14-30% annually. In addition to use in brackish water reverse osmosis, desalination, but also widely used in many fields of pure water preparation, wastewater treatment and drinking water, beverage concentrates and chemical products, recycling processes. Reverse osmosis desalination systems and equipment in accordance with the principles of osmotic principles, there is a "chemical potential" of the difference on both sides of a semipermeable membrane, permeation process through a solution of the chemical potential difference is compensated. When the balance is re-established on both sides of a semipermeable membrane is formed of a net difference of a water pressure, the pressure is the osmotic pressure. The nature of the osmotic solution itself, depending on the concentration of the solution, there is no relationship with the semipermeable membrane.
