Send InquiryIntroduction
The DTRO technology is currently able to guarantee the stability of leachate effluent in China.
DTRO system can be used in combination with other processes as the pre-discharge treatment process, which can ensure that the leachate is reliably up to standard after treatment.
The structure of the DTRO membrane module is completely different from the traditional roll membrane. The structure of the DTRO membrane module is completely different from the traditional roll membrane. The original liquid flow channel: The disc tube membrane module has a special flow channel design form and uses an open flow channel. The material liquid enters the pressure vessel through the inlet, and flows from the channel between the deflector and the shell to the other end of the module. At the other end flange, the material liquid enters the deflector through 8 channels. The shortest distance quickly flows through the filter membrane, then 180º reverses to the other membrane surface, and then flows from the notch in the center of the deflector to the next deflector, so that the membrane surface is formed from the circumference of the deflector to the center of the circle. To the circumference, and then to the double "S" -shaped route in the center of the circle, the concentrated liquid finally flows out from the flange at the feed end.

Equipment characteristics
Avoid physical clogging The DTRO component adopts an open flow channel design, and the effective flow path of the material liquid is wide to avoid physical clogging.
Minimum scale and pollution
Adopting a deflector with a bump support, the turbulent state of the material liquid during the filtration process, which minimizes the generation of scaling, pollution, and concentration polarization on the membrane surface, allowing highly polluted water sources with SDI values of up to 20 There is still no risk of contamination.
Long membrane life
DTRO membrane module effectively reduces membrane fouling, reduces membrane pollution, and has a long cleaning cycle. At the same time, DT's special structure and hydraulic design make the membrane group easy to clean, and the flux recovery is very good after cleaning, which prolongs the life of the membrane. Practical engineering shows that even in the direct treatment of the permeate stock solution, the lifespan of the DT diaphragm can be as long as more than 3 years, which cannot be achieved by ordinary membrane treatment systems.
Components are easy to maintain
The DTRO membrane module adopts a standardized design. The module is easy to disassemble and maintain. Opening the DTRO module can easily check and maintain any piece of filter membrane and other components. The maintenance is simple. When the number of parts is not enough, the module allows less membranes and deflectors. Does not affect the use of DT membrane modules, all these maintenance work can be completed on site.
Low filter membrane replacement costs
Any single component inside the DTRO assembly can be replaced individually. The filter part is assembled by multiple filter membranes and deflectors. When the filter membranes need to be replaced, they can be replaced individually. The membranes with good filtering performance can still be used, which reduces the cost of membrane replacement.
High concentration factor
DTRO module has three operating pressures of 75bar, 150bar, and 200bar. It is the membrane module with the highest pressure in industrial applications. In some applications with high concentration factors, the solid content can reach more than 25% and the concentration factor is high.
