Pure Water Equipment Series - Reverse Osmosis (Ultra) Pure Water Device

reverse osmosis
(abbreviated as PO) is a type of membrane separation technology. The principle is to use sufficient pressure to separate the solvent (usually water) in the solution into water through a reverse osmosis membrane. As its operation is opposite to the normal permeation process in nature, it is called reverse osmosis (or reverse osmosis). With the development of membrane technology, membrane performance continues to improve, and reverse osmosis technology will develop into a new chemical separation technology for separation, classification, purification, and enrichment.
The main characteristics of reverse osmosis technology are:Low energy consumption, compact structure, simple operation, easy maintenance, high degree of automation, and no environmental pollution.
Reverse osmosis technology is widely used in water treatment, purification of urban tap water, preparation of pure and ultrapure water, injection water, and edible pure water in industries such as electricity, electronics, medicine, healthcare, and food; Desalination of seawater and brackish water; Producing drinking water, etc.
The reverse osmosis system consists of three parts: pre-treatment, reverse osmosis device, and post-treatment. The core of a reverse osmosis system is the reverse osmosis device. Pre treatment is a prerequisite for the long-term stable operation of the reverse osmosis device, while post-treatment is used to meet the water quality indicators of different treatment objects.

ultrafiltration device
It is a membrane permeation device that can purify and separate solutions, typically retaining solute molecules with a molecular weight between 500-500000. Its ultrafiltration membrane is in the form of a hollow capillary tube with densely packed micropores on the tube wall. Raw water or solutions that need to be treated flow through the tube under pressure, and water and small molecule solutes pass through the membrane wall to form ultrafiltration solution. Large molecule substances, called concentrated solution, are intercepted and discharged, thus achieving the purpose of purification and separation.
Application of ultrafiltration device
In the pure water preparation process, ultrafiltration can be used as a pre-treatment or ion exchange terminal filtration for reverse osmosis to remove colloids, microorganisms, mechanical impurities, and ion exchange resin fragments; Used in pharmaceutical processes to prepare sterile purified water without heat source; Used for sterilization and clarification in the pharmaceutical and formulation industries; Sterilization of beverage mineral water and treatment of industrial wastewater from textile, chemical, and environmental industries.
Reverse osmosis device
It is currently a desalination equipment that uses a roll type composite membrane and is suitable for purifying water under low-pressure operation. It can remove various metal ions, acid radicals, bacteria, pyrogens, and radioactive pollutants from water, with a desalination rate of over 99.8%. Due to its advantages of easy operation, stable operation, energy saving, good pollution resistance, and long service life, it is the preferred equipment for producing pure water in fields such as electronics, power, hospitals, pharmaceuticals, food and beverage, and chemical engineering.
