A unique structure of reverse osmosis technology is known as duck-tube reverse osmosis (hence referred to as “DTRO”). The reverse osmosis membrane and a set of hydraulic discs are firmly joined into a cylinder through a stainless steel tube with screw teeth at both ends to form the disc-type membrane column, which is the main component of the DTRO.
Reverse osmosis membrane blockage and concentration polarisation are successfully avoided, and the service life of the membrane is successfully extended, thanks to this unique hydraulic design that allows the treated liquid level to pass through the membrane quickly and over the shortest distance before turning around and returning to the other membrane surface.
A patented piece of membrane separation equipment, DT membrane technology is the disc tube membrane technology, separated into DTRO (disc tube reverse osmosis membrane module) and DTNF (disc tube nanofiltration membrane module). This method was created specifically to handle insulin waste water.
The leachate from landfills contains a variety of insoluble salts, including calcium, magnesium, silica, and barium. When these insoluble inorganic salts enter the reverse osmosis system, they become highly concentrated. The film will be in the film when the concentration surpasses the solubility under the circumstances. The floor has been contaminated.
The pH of the raw water must be adjusted before going through the reverse osmosis process in order to successfully prevent the scaling of the carbonate inorganic salt. Using the DTRO feed pump, the MBR effluent is fed into the membrane column. In order to achieve a pH that is balanced, acid is introduced from the acid storage tank at the same time that reflux mixing is carried out.
The Global DTRO Membrane Equipment market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The most cutting-edge products in DT membrane module technology are known as DT membrane, RCDT membrane (Radial Channel Disc Tube membrane module), or PT membrane (Plate Tube membrane module). (DTRO) and are the two most popular DT membrane products (DTNF).
RisingSun Membrane is a well-known producer of Disc Tube RO (DTRO), also known as RCDT membrane modules, which are used mostly for treating high TDS/COD waste water and landfill leachate.
Although the MBR effluent has had the majority of the organic matter and nitrogen pollutants removed, they still fall far short of the emission criteria. However, there are still many pollutants in the water, including scale ions and organic debris, which poses a significant concealed risk to the subsequent, reliable operation of membrane separation machinery.
The revised standard also includes a requirement for total nitrogen index in addition to the high emission threshold. Nitrates must be rejected by the membrane system with a high rate. DTRO is used in this design (disc tube anti-pollution ability and high recovery rate). system of osmotic membranes).
