1000L/H Double Stage Ro Water Purification Machine For Food Production Use
Reverse osmosis membrane
Ordinary water treatment with reverse osmosis membrane temperature is 0 ~ 45℃, but in the need of 90℃ high temperature sterilization special occasions, can use high temperature resistance, chemical resistance of reverse osmosis membrane. In addition, a variety of food grade or sanitary grade reverse osmosis membranes with special membrane element structures have also begun to be used.
Working Principle of Reverse Osmosis Water Treatment System:
When a pressure greater than osmotic pressure is applied on the saltwater side of the membrane, the flow of water is reversed and the water in the saltwater flows into the fresh side, a phenomenon called reverse osmosis.

Process flow of reverse osmosis water treatment system:
Raw water → original water tank → original water pump → multi-media filter (quartz sand filter)→ activated carbon filter → soft water processor → precision filter → high pressure pump → first stage reverse osmosis (RO) device → pure water tank → high pressure pump → second stage reverse osmosis → ultraviolet sterilization device → water point
Application of reverse osmosis membrane:
The largest field of reverse osmosis membrane industry application is still large boiler supply water, a variety of industrial pure water, drinking water market size next, electronics, semiconductor, pharmaceutical, medical, food, beverage, wine, chemical, environmental protection, metallurgy, textile and other industries have also formed a certain scale of membrane application. The potential application areas in the future are sewage treatment of cooling circulating water in power plants, large-scale seawater desalination, brackish water desalination, large-scale municipal and industrial wastewater treatment, etc.
FAQ:
1, What are the inlet water quality requirements for ro water treatment system membrane components?
| NTU | SDI | Residual chlorine(mg/L) | Fe2＋(mg/L) | TOC(mg/L) |
| Limits | ≤1 | ≤5 | ≤4 | ≤3 |
2. What is the material of ro water treatment system membrane?
Acetate membrane (CA) : mainly because of its resistance to chlorine, so it is still durable. But its suitable pH range is small, easy hydrolysis
Aromatic polyamide membrane (PA) : water almost can not have chlorine, only through a variety of pretreatment chlorine.
3. RO water treatment system configuration:
First-stage multi-stage process: if the recovery rate is not achieved in the first stage (50-65% in the first stage and 65-75% in the second stage), the multi-stage tandem filtration can be used. The effective cross-sectional area of each segment decreases. 2:2 and 2:3 and 4:2:1
Multi-stage process: when the first stage process cannot meet the effluent quality requirements (the first stage is generally ≤20μs/cm), the product water of the first stage process is sent to another reverse osmosis unit.
The arrangement of membrane components can be divided into series and parallel.
