Reverse osmosis desalination plant rich students FIG _ _ waste water 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. Because of the reverse osmosis process and system control equipment is relatively simple, in general, to analyze and understand the impact of their form factors can be easily managed. Can long-term stable operation of the reverse osmosis system in addition to the device's performance by the wood itself outside the normal operation and maintenance of equipment operation is essential. When the reverse osmosis membrane fouling equipment occurs, fouling, mechanical damage and other phenomena membrane elements, reverse osmosis system operating pressure, water production, desalination rate, pressure and differential pressure and other technical indicators will show abnormalities. Active layer damage, even in the course of the reverse osmosis membrane element surface contamination sometimes overshadowed the film formed on the surface, but in the reverse osmosis system with drugs for the first CIP cleaned, damage the film will be revealed in this case next, engineering companies and users should be able to correct a number of ways to make its judgment, determines that the reverse osmosis membrane system resulting in poor performance of the real reason. In general, if the original data during operation of the various items recorded directly as objectivity comparable data it is difficult. The reason is that each item of information is due to the different running time, place, and human factors change, to eliminate the influence of this factor brings, we have to run after the initial steady state conditions of the device as a reference, this reference the measured results with the corresponding device status judgment, which is a standardized reverse osmosis system operating data. Standardized equipment operating data for the device operation status determination is very important to understand what it really means is that changes in the degree of change in device performance and capability in order to enable users to timely make appropriate improvements and adjustments.
