Product Description


Industry RO Water System Overview

    Reverse osmosis is a kind of membrane separation technology developed since 

the 1980s.It mainly uses the osmosis principle of semi_transparent membrane.A 

pressure that is reverse to the osmosis direction is exerted by a certain method

 so as to make reverse osmosis.The device that is composed of reverse osmosis 

components is called reverse osmosis device. 

Primary and secondary reverse osmosis+EDI device

1. Applied in areas where the salinity of raw water is high;

2.Good electric conductivity of water produced;

3.Low investment;

4.Low operating cost;

5.Good stability.



Characteristic of purified water produced by RO and EDI:


Water quality is good , conductivity can reach 16MΩ•CM;

Degree of stability for water quality is optimal ;

Can produce ultra-purified water complying with use`s requirement continuously ;

Modularization , full automatic control ;

No need rebirth of acid and alkali , no sewage drain ;

Operate simply , low labor strength ;

Can not stop machine for rebirth;

No rebrith equipment and chemical storage and transportation ;

Structure of equipment is compact , lillte location ;

Running and maintenance cost is low ;

Control system : to meet the user different control requirements , using PLC

 automatic control technology.


Industry RO Water System Workflow

 Suspended solids and colloids of drinking water removed by multi_media filter, and activated carbon filter to remove chlorine ions; then through precision filter and 

primary high_pressure pump to primary reverse osmosis,the water enters into the 

intermediate tank, and then through secondary high_pressure pump to secondary 

reverse osmosis, and then into the EDI deviceproduced water is storaged in 

purified water tank. 

    The material of purified water pipes is 316L stainless steel, arc welding, and the 

slope in drainage direction for pipes horizontal installed is not less than 5 ‰.


Packaging & Shipping


     It is suitable for sea shipment, and usually packed in wooden box. The detailed 

packing should check with us, and subject to the final packing.
