Reverse osmosis technology process
 
RO membrane itself is sensitive to the pH, temperature and specific chemicals of the influent. The water quality of the influent strictly requires the pH value range of 4~10, temperature <40℃, silt density index SDI<5, free chlorine <0.1mg·L-1, turbidity <1, iron content <0.1mg·L-1, etc. In order to meet the requirements of RO membrane water, raw water before entering the RO membrane system must first preprocessing (sedimentation, coagulation and microfiltration, ultrafiltration, activated carbon absorption, pH adjustment, etc.), then the pump pressure into the membrane module, the pressure under the action of raw water as water production through the RO membrane, and inorganic salts, organic matter and particle by RO membrane intercept on the other side of the membrane to form thick liquid. The concentrated solution can be recycled or reprocessed according to the requirements of the specific process. RO can be used with ultrafiltration, nanofiltration and other membrane devices to form an integrated membrane device.
 
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.
 
Technical Specifications of Reverse Osmosis Water Treatment System:
 

 
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

 
 
Ro water treatment system concentrated water treatment
RO water treatment process for water separation, inevitably will produce concentrated water, concentrated water is the main characteristics of the salt content is relatively large, due to strict RO water, so concentrated water chroma, turbidity, and organic matter content are relatively low. According to the characteristics of RO concentrated water, RO system can be reused after adding scale inhibitor, adjust the proportion of concentrated water and water intake, to achieve recycling; If the content of a valuable ion in concentrated water is high, the ion can be further concentrated and purified. Zhan Jinkun also verified the feasibility of RO concentrated water as ultrafiltration backwashing water, which is also a new method of RO concentrated water utilization.
 

 
FAQ:
 
1, What are the inlet water quality requirements for ro water treatment system membrane components?

 
 
 
 
 
 
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.
