Reverse Osmosis Equipment Overview - Clean Water Technologies - Industry News - Global network of wa
Overview of reverse osmosis equipment since the 1970s the introduction of reverse osmosis membrane desalination technology, so far there are 20 years of history. With the improvement of the performance of the reverse osmosis membrane element, the technique has been widely used in various fields of power, petroleum, electronics, food / beverage, hospital / pharmaceutical, desalination. Reverse osmosis membrane separation process is the use of water treatment technology, is the nature of the phenomenon of permeation inverse process (to the outside of saline water molecules urging force to overcome the osmotic pressure of the reverse osmosis process through the membrane). 1. Reverse osmosis water desalination process is essentially a physical method, which has the advantage of no conventional water treatment methods in many aspects: · RO is at room temperature, no phase change physical method will saline feed water desalination, purification. At present, the thin membrane desalination element of 99.5% water and also removal of colloids, organic matter, bacteria, viruses and the like. Pressure treated water alone as the driving force of the water, which is the lowest energy consumption in a number of treatment methods. · A large number of chemicals and without acid, alkali regeneration process, no chemical waste and waste acid, lye emissions, no environmental pollution. * Reverse osmosis water means may be continuously run, the system is simple, convenient operation, product water quality and stability. · Operation and maintenance and equipment maintenance workload rarely. · Equipment small footprint, the space required is also small. · Raw water quality to adapt to a wide range of both adapt to brackish water, sea water and even sewage disposal, but also to adapt to a low-salt amount of fresh water treatment. 2. The membrane characteristics and conventional hollow fiber, flat membrane, and different volumes, in order to adapt the direct process water turbidity, tubular ultrafiltration membrane having a membrane structure of the patented technology, which has the following characteristics: film material polyether sulfone materials, long service life. · Resistant chlorine, potassium permanganate, ozone, a strong oxidizing agent, it can be chemically bonded iron oxide, and manganese. Resistant to acid, alkali, acid and alkali can be an ordinary chemical cleaning. · Tubular film high mechanical strength, good tensile strength. · Strong adaptability to raw water quality, excellent effluent quality, stable, free from changes in raw water quality changes. · Strong resistance to biological contamination, are not biodegradable, easy to clean and restore.
