Nowadays, how to effectively treat and reuse wastewater has become one of the key issues in industrial water treatment. Disc-Tube Reverse Osmosis (DTRO) membranes have gained wide user recognition due to their stability, simple operation, and low cost.

The new Disc-Tube membrane modules (XDTRO) use membrane raw material from the American company Dow and are produced automatically utilizing German technology and equipment, ensuring excellent quality. They are now widely used in fields such as molecular separation, desalination, and liquid purification. Disc-Tube membrane modules have broad application prospects in high-concentration industrial wastewater treatment, high-salinity water concentration, landfill leachate treatment, brackish water desalination and purification, and domestic wastewater reuse.

Our patented fluid dynamics design, unique open channel design, and sufficient turbulence greatly improve the anti-fouling and anti-scaling capabilities of the Disc-Tube membrane modules. There are virtually no limits on feedwater SS; a Silt Density Index (SDI) of less than 40 is acceptable; salinity can be greater than 5%; feedwater COD can reach up to 20,000 mg/L. The membrane modules can achieve rejection rates for salts and COD as high as 99%+, with a water recovery rate that can reach over 90%, and an overall membrane lifespan of 3-5 years. They are the only reverse osmosis membrane elements that can be disassembled for cleaning and maintenance.

Application areas of DTRO (Disc-Tube Reverse Osmosis) include:
1.Pharmaceuticals (desalination and concentration of antibiotic resin eluates, vitamin concentration)2.Dyes (desalination and concentration, replacing salting-out and acidification)3.Amino acids (decolorization, impurity removal, concentration, desalination)

4.Food (separation and purification of oligosaccharides and starch sugars, juice concentration, plant extraction)
5.Mother liquor recovery (impurity removal from MSG mother liquor, glucose crystallization mother liquor, etc.)
6.Water treatment (treatment of printing and dyeing wastewater, water reclamation, ultrapure water production)
7.Acid and alkali recovery (acid/alkali waste from column cleaning in pharmaceuticals, waste acid/alkali in the chemical fiber industry,

Operational knowledge for using Disc-Tube ultrafiltration membranes in filtration systems:

1.Note: Regular sterilization of the equipment is necessary.

Typically, Disc-Tube ultrafiltration membranes can retain very small impurities or bacteria, so the water filtered through them is very clean. However, it's important to note that while they can filter out bacteria, they cannot kill them. Therefore, regular sterilization is essential; otherwise, too many bacteria and germs will accumulate in the system, affecting filtration efficiency. Therefore, manufacturers recommend frequent maintenance in this regard, deciding the sterilization interval based on the specific situation.

2.Note: Determining the water flux requires considering many factors comprehensively.

To achieve excellent filtration system performance, the number of filtration components must be arranged according to the total required water flux. Therefore, the permeation flux rate and relevant coefficients must be measured and calculated beforehand to allow for rational configuration and selection of the appropriate number of Disc-Tube ultrafiltration membranes to treat the required water volume within the specified time. Furthermore, manufacturers note that since water flux can change due to factors like pressure, temperature, and feed concentration, these must be considered comprehensively during setup.

3.Note: Handle with care to protect the instruments and equipment.

Generally, components related to Disc-Tube ultrafiltration membranes are very delicate and should not be knocked. Therefore, they must be handled with care during use, stored in dedicated boxes to prevent breakage, and installed cautiously. Manufacturers also recommend that after shutdown, the relevant components should be cleaned in clean water, disinfected with a formaldehyde solution, dried, and then sealed.

Additionally, when using Disc-Tube ultrafiltration membranes, it is essential to carefully read the manual before use and strictly follow its requirements during operation. Also,note that the components must be thoroughly flushed of the preservative solution before use, and ensure all product water discharge valves in the entire system are fully open.
