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

limited.
