Reverse osmosis membranes are the core of the entire reverse osmosis water treatment process. The precision of reverse osmosis membranes is 0.0001 microns. Due to their high precision, the requirements for water quality are also relatively high. Therefore, if the quality of the raw water is poor, it will damage the RO membrane. Before reverse osmosis, there are precision self-cleaning filters with a precision of 5um, sand filters and carbon filters. If the water quality is poor, scale inhibitors need to be added.

Raw water pretreatment is also called feed water pretreatment. In water treatment, advanced treatment systems, especially membrane systems, often have certain water quality requirements for the influent. To extend the cycle and service life of the system and prevent its damage, it is generally advisable to improve the quality of the influent water as much as possible. The raw water obtained from the water source will then undergo certain pretreatment. To ensure the stable operation of reverse osmosis and nanofiltration systems, strict treatment of feed water is indispensable. The purpose of pretreatment is to remove substances in the feed water that may contaminate or deteriorate reverse osmosis and nanofiltration membranes. Once the pretreatment system fails to function properly and contaminants enter the reverse osmosis and nanofiltration systems, these substances may accumulate on the membrane surface. If the feed water contains microorganisms, their reproduction will lead to more serious consequences. It is of great significance to accurately grasp the characteristics of raw water and design and select an appropriate pretreatment process. The Century Source ultrasonic self-cleaning filter has a filtration accuracy of up to 2 microns and is equipped with an ultrasonic generator to combine ultrasonic waves with water filters. This ultrasonic self-cleaning filter is mainly used for water purification, sterilization, scale inhibition, and organic matter degradation, especially in the microfiltration field where water quality requirements are high. Its main functions include removing impurities such as sediment, clay, rust, suspended solids, algae, biofilm, corrosion products, macromolecular bacteria, fungi, organic matter, protozoa and other tiny particles from water. At the same time, it has multiple functions such as ultrasonic sterilization and algae removal, scale inhibition and COD reduction, achieving the purpose of water purification. The Century Source ultrasonic water filter adopts 316L stainless steel sintered mesh. The filter element needs no replacement for life. It features high-pressure fully automatic backwashing, which does not affect the normal operation of the machinery.

The domestic ultrasonic self-cleaning filter reverse osmosis pretreatment industrial application field is still mainly large boiler feed water, various industrial pure water, followed by the market size of drinking water. The application in the electronics, semiconductor, pharmaceutical, medical, food, beverage, wine, chemical, environmental protection and other industries has also formed a certain scale.

Century Source Ultrasonic Self-cleaning Filter - Precision filter is applied in the pretreatment of reverse osmosis raw water, which effectively protects the normal operation of reverse osmosis membranes and extends their service life.
