RO water treatment system
Introduction to the system
Water supply treatment composes of water for beverage foods processing, water for electronic medicine and water for industry. The water sources for water supply treatment compose of surface water and under ground water. Surface water is also named as over ground water and refers water in the river, lake and reservoir, and features relatively salt content and hardness, water quality is unstable and has big changes according to the season. Under ground water means the water in deep well which is excavated manually, and features more salt with stable water quality which won’t change according to the season.
Introduction to Water treatment system
The technology a set of water treatment system uses depends on water quality and purpose of water use. The adopted technologies can basically be divided into pre-treatment system, depth treatment system and terminal treatment system. Pretreatment system includes media filter, active carbon filter, softener, iron and manganese filter, ultra-filtration, micro-filtration, etc; advanced treatment includes membrane method treatment and ion exchange; aftertreatment system includes sterilization and ion exchange, etc.
Pretreatment system
Pretreatment system refers to using mechanical filtration, absorption and coagulation to remove soap grains, colloid, suspended substances, free residual chlorine and organic as much as possible and lowering turbidity, colority, stink and hardness of influent water to guarantee pretreated water meets the requirements of depth salt-removing system.
Main Features
1) side port2) FRP twisted case 3) Thread connection at fresh water outlet: 1/2" female thread4) Working pressure: 300 to 1,200psi5) Internal diameter: 101mm6) Available lengths: 1, 2, 3, 4, cores (the numbers of membrane element)7) Operating temperature: -7°C ~ 49°C
Advanced treatment system
Ion exchange technology was adopted in depth treatment system in China in early days. Because ion exchange needs acid-alkali reclaiming treatment after a period of use, its reclaiming solution is apt to pollute the environment after it’s discharged and the maintenance cost is relatively high. Membrane method treatment matured at technology is more widely employed now. Membrane method treatment includes ultra-filtration, reverse osmosis and ion filtration. Ultra-filtration is generally used in pretreatment instead of depth treatment system. Reverse osmosis primarily removes salt, metal ion and microbe in water to guarantee final effluent water is qualified for the influent water requirements of terminal treatment system.
Main Features: simple operation, convenient maintenance;
Automatic or manual working.
Water discharged from the system won’t cause any pollution to the environment;
Compared with traditional salt removal equipments such as electrodialysis and compound machine, it doesn’t need acid and alkali regeneration with low cost in maintenance and low occupation.
