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

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.
