Small Size Water Filter 500LPH One Stage RO Water Treatment System
 
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.
 
Technical Specifications of RO Water Treatment System
 

The latest development of RO membrane includes inorganic membrane, hybrid membrane and novel organic membrane. Theoretically, inorganic membrane has high ion interception performance, but its high cost and harsh preparation conditions are not conducive to industrial application. Hybrid membrane combines the advantages of organic materials and inorganic materials, which has a good application prospect in improving membrane separation performance and anti-pollution, and has great development potential, which needs further theoretical research. The preparation of new organic membranes is still in the primary stage, and the main purpose is to improve membrane flux and chemical stability, but no breakthrough has been achieved.
 
Process flow of RO Water Treatment System
Raw water → Raw water tank → Raw water pump → Multi-media filter (quartz sand filter) → Activated carbon filter → Soft water processor → Precision filter → High pressure pump → Primary reverse osmosis (RO) device → Purified water tank → High pressure pump → Two Stage reverse osmosis → ultraviolet sterilization device → water point.
