DTRO Garbage Leachate Treatment Sewage Equipment Garbage Transfer Station Leachate Sewage Treatment System Reverse Osmos

1.Introduction to DTRO
DTRO stands for Disc Tube Reverse Osmosis, and the core of the disc tube reverse osmosis system is the disc tube membrane column. The DTRO membrane column is specifically designed for high concentration water sources and has an open channel, suitable for various water sources. Due to the spacious channel (1.3mm) between the membrane and the guide plate, the SDI value of the wastewater entering the membrane group can reach 20. The special structure and hydraulic design of DTRO components make the membrane assembly easy to clean, avoiding scaling and other membrane fouling.
The structure of DTRO membrane module is completely different from traditional roll type membrane. The membrane module adopts an open flow channel, and the feed liquid enters the pressure vessel through the inlet. From the other end of the membrane module through the channel between the guide plate and the shell, at the other end flange, the feed liquid enters the guide plate through 8 channels. The processed liquid flows quickly through the filter membrane at the shortest distance, then reverses 180 ° to the other membrane surface, and flows into the next guide plate through the slot in the center of the guide plate, thus forming a double "S" - shaped path from the circumference of the guide plate to the center of the circle, then to the circumference, and finally to the center of the circle on the membrane surface. The concentrated liquid finally flows out from the inlet flange.
The core of the DTRO system is a disc tube membrane column, which is formed by tightly assembling a set of hydraulic discs and reverse osmosis membranes into a cylindrical shape through stainless steel pipes with screw threads at both ends. The membrane column has a diameter of 200 millimeters and a length of 1500 millimeters, consisting of 210 guide disks and 209 membranes.
The DTRO system includes: disc tube reverse osmosis membrane, high-pressure pump, online booster pump, pressure regulating valve, inlet solenoid valve, concentrated water flow meter, purified water flow meter, inlet pressure gauge, outlet pressure gauge, switch and indicator light, online pH, conductivity tester, etc. It is an automatic, manual electric control and PLC self-contained system, and the central control computer and on-site touch screen of the equipment can achieve control of the treatment process.
2. The progressiveness of the disc tube reverse osmosis membrane treatment system lies in:
2.1 Due to the special fluid dynamics design of the DTRO membrane group, it is suitable for treating wastewater with high turbidity and high sand content coefficient. For a typical roll type reverse osmosis system, the sludge concentration index (SDI) entering the membrane group wastewater cannot exceed 3, and the sand content coefficient cannot exceed 3. Due to the spacious channel between the DTRO membrane and the guide plate, the SDI value of the wastewater entering the membrane group can reach 20, and the sand content coefficient can also reach 40.
2.2The DTRO membrane group has less fouling, reduces membrane fouling, and prolongs the lifespan of the reverse osmosis membrane. The special structure and hydraulic design of DTRO make the membrane assembly easy to clean, avoiding scaling and other membrane fouling, thereby extending the lifespan of the membrane. The membrane used for DTRO can have a lifespan of up to 3-5 years, or even longer, which is not achievable for typical roll type reverse osmosis treatment systems.
2.3The DTRO processing system is easy to install and maintain, easy to operate, and has a high degree of automation. Due to the fact that the pipelines and spare parts used in the DTRO system are mostly standard components, installation and maintenance are relatively convenient.
A first-class automated operating system: The longevity of a system is inseparable from the quality of its operational management mode. The system is highly sensitive to various technical indicators such as operating pressure, medium conductivity, pH value, and pressure difference. A good operating system and management mode can extend the service life of the membrane and reduce operating costs.
