2TPH Stainless Steel Ro Water Treatment System For Drinking Water Production

What is Reverse Osmosis Water Treatment System?

Reverse osmosis water treatment system is usually composed of raw water pretreatment system, reverse osmosis purification system and ultra-purification post-treatment system. Membrane separation technology is applied to remove charged ions, inorganic matter, colloidal particles, bacteria and organic matter from water. Reverse osmosis membrane system is the most economical and efficient purification method to remove more than 98% ions, organic matter and 100% microorganisms (theoretically) in raw water at one time.

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

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.

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.
