DTRO Disc Tube RO Membrane Filter Module for High Salts Water Treatment
Disc tube membrane technology is DT membrane technology, which is divided into DTRO (disc tube reverse osmosis), DTNF (disc tube nanofiltration), DTUF (disc tube type nanofiltration) There are three categories of tubular ultrafiltration, which are membrane modules specially used to treat high-concentration sewage. The core technology is the disc tube membrane column. put the diaphragm.It is stacked with the hydraulic deflector, fixed with the central pull rod and the end plate, and then placed in the pressure-resistant casing to form a membrane column.
DT series products overcome the shortcomings of common reverse osmosis systems that are easy to block when treating leachate, making the system more stable and operating costs lower. The service life of DT membrane column can be as long as more than three years.

1) When the pH value is greater than 10, the maximum temperature for continuous operation is 35 °C. When the influent water contains free chlorine or other oxidizing substances, the
Because its oxidizing properties can seriously damage the performance of the membrane, users are advised to remove free chlorine or other oxidizing substances in the pretreatment.
Before each start-up, the pressure of less than 0.2MPa must be used, and the flow rate of each DT membrane should not be higher than 600L/H to discharge the membrane module.
The high-pressure pump can be started only after the air is completely filled with water for 5 minutes;
2) The recommended water intake of each DT membrane module is 800-1200L/H, and the flow rate cannot exceed this flow range at any time during normal operation.
It is recommended that each membrane enters 1000L/H of water;
3) In order to prevent the tightening thick nut (part number 2) from loosening due to vibration during transportation, a torque wrench should be used when the new equipment is turned on.
Tighten the nut by hand with a torque of 110NM.
4) It is strictly forbidden to test the membrane module under the condition of tap water. The size of the permeate center pipe of the DT module is designed according to the high-concentration salt water condition, and the low salt water
Under high pressure, the fresh water flow is too large and cannot flow out in time, which will cause the back pressure of the diaphragm to damage the module. For test conditions, please consult Zhejiang Tefen Environmental Technology
limited.
