Double Pass RO Water Purifier Drinking Water Desalination Machine

What is Reverse Osmosis Water Treatment System?

Reverse osmosis system includes high pressure pump, reverse osmosis membrane element, pressure vessel (membrane case), cleaning system and control instrument

The pore size of reverse osmosis membrane is as small as nanometer (1 nanometer =10-9 meters). Under a certain pressure, H2O molecules can pass through RO membrane, while inorganic salts, heavy metal ions, organic matter, colloid, bacteria, viruses and other impurities in the source water cannot pass through RO membrane, so that the pure water that can be permeated and the concentrated water that cannot be permeated can be strictly distinguished.

Technical Specifications for RO Water Treatment System

Working Principle of RO Water Treatment System

After a special high-pressure pump, when the raw water is added to a pressure of 6-20 kg, the raw water permeates through the reverse osmosis membrane with a pore size of only 0.0001 microns under the action of pressure. Chemical ions, bacteria, fungi, and virions cannot pass through, and are discharged with wastewater. Only water molecules and solvents with a volume of less than 0.0001 microns are allowed to pass through.

Application of RO Water Treatment System

1, seawater desalination, brackish water desalination

2, industrial pure water, boiler supply water manufacturing

3, drinking water municipal water supply, drainage, water treatment

4, cooling circulating water, industrial, municipal sewage treatment

5, food, pharmaceutical and various processes of water, semiconductor ultrapure water manufacturing

6. Desalination of various aqueous solutions

7, surface water turbidity removal, wastewater treatment and decolorization

8. Municipal landscape and agricultural irrigation

9. Separation, concentration, separation and concentration of dairy products

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.

4. What is the design water yield of ro membrane element? (except anti-pollution membrane and seawater desalination membrane)

Model 4040 is designed by 0.25m3/h

Model 8040 is designed by 1-1.2m3/h

5. What is the material of mechanical filter?

Carbon steel, stainless steel, fiberglass

6. what are the multi-way control valves?

Manual control valve, automatic control valve

Multi - way control valve is divided into: filter valve and softening valve

Automatic control valve is divided into: time type and flow type.

Multi-way control valve brands are: FLECK, AUTOTROL, Runxin, clean source, etc.
