200TPH Landfill leachate reverse osmosis treatment Water Filtration Plant

Unique characteristics of RO Water Treatment System

1. The single-membrane desalination rate can reach 99%, the desalination rate of the primary reverse osmosis system can generally be stabilized above 90%, and the desalination rate of the secondary reverse osmosis system can generally be stabilized above 98%.

2. Because the reverse osmosis equipment can effectively remove microorganisms, organic substances and inorganic substances such as iron and silicon, the quality of the effluent is higher than other methods.

3. The equipment has small footprint, compact structure, reliable operation and convenient operation.

4. The system is simple, the degree of automation is high, the fault is automatically shut down, and it has the function of automatic protection.

5. The recovery rate can reach more than 70%.

6. Save the chemical consumption cost, labor cost and waste water treatment cost generated by regeneration, and reduce environmental pollution.

Reverse osmosis membrane contamination:

RO membrane contamination is another important factor that restricts the wide application of RO technology. Membrane contamination not only affects the stable operation and effluent quality of the membrane, but also shortens the service life of the membrane. For membrane contamination, the main methods are:

(1) Improve the pretreatment system to ensure the RO system inlet water quality;

(2) RO membrane cleaning, chemical analysis of membrane pollutants, choose the best cleaning agent and cleaning method;

(3) Regularly stop and maintain the RO membrane device.

Process flow of RO 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
