Anonymous users2024-02-07DTRO membrane is a form of reverse osmosis, which is a membrane module specially designed to treat high-salt wastewater treatment, and its core technology is a disc tube diaphragm membrane column. The reverse osmosis diaphragm and the hydraulic diversion plate are stacked together, fixed with a central tie rod and end plate, and then placed into the pressure-resistant sleeve to form a membrane column. DTRO membranes are widely used in high-salt wastewater treatment.
DTRO membrane because of its membrane module structure and the traditional spiral membrane, completely different, dope flow channel: disc tube membrane module has a flow channel design form, using an open flow channel, the material liquid enters the pressure vessel through the inlet, flows from the channel between the deflector plate and the shell to the other end of the module, at the flange at the other end, the material liquid enters the deflector tray through 8 channels, and the treated liquid quickly flows through the filter membrane at a short distance, and then reverses to the other membrane surface at 180°, It then flows from the notch in the center of the deflector plate to the next deflector plate, thus forming a double "S" shaped route on the surface of the membrane from the circumference of the deflector disc to the center of the circle, then to the circumference, and then to the center of the circle, and the concentrate flows out from the flange of the feed end. The distance between the two deflector plates of the DTRO membrane module is 4mm, and the surface of the deflector plate is arranged in a certain way.
This special hydraulic design enables the treatment liquid to flow through the surface of the filter membrane under pressure to form turbulence when it encounters radiation collision, increasing the permeability rate and self-cleaning function, thus effectively avoiding the phenomenon of membrane blockage and concentration polarization, and successfully prolonging the service life of the diaphragm. It is also easy to clean the fouling on the diaphragm during cleaning, ensuring that the disc tube membrane pack is suitable for treating wastewater with high turbidity and high sand coefficient, so the DTRO membrane is suitable for harsher influent conditions for high-salt sewage treatment.

Anonymous users2024-02-05DTRO membrane is a high-efficiency membrane separation technology emerging in China in recent years, which is a membrane permeability treatment technology that filters, separates and concentrates solutions. With the continuous breakthrough of domestic technology, DTRO membrane occupies a significant position in domestic industrial high-salt wastewater treatment and has been widely used in industrial high-salt wastewater treatment.
Under the pressure of the DTRO membrane, the feed liquid enters the pressure vessel through the inlet, and flows from the channel between the deflector plate and the housing to the other end of the assembly. At the other end of the flange, the liquid passes through the channel into the deflector pan, and the liquid being treated flows quickly through the membrane over a short distance and then reverses to the other membrane surface. DTRO membrane technology can not only filter out impurities and particulate matter like traditional water treatment technology, but also filter COD, BOD, ammonia nitrogen, etc. in water, with good filtration effect, so it has been widely used in industrial high-salt wastewater treatment.

Anonymous users2024-02-03Advantage 1: Fouling resistance.
Causes of fouling resistance
Channel width - the fluid channel to be treated is 2mm wide and has no partition, and the roll package is resistant to fouling
Short process - the liquid flow on the membrane surface is 7cm, and the roll-encapsulated membrane module is 100cm anti-fouling
Turbulence - The bumps on the deflector plate form high-velocity turbulence under the action of high salt, increasing the self-cleaning and passing rate.
Advantage 2: High pressure resistance.
The special structure of the center tie rod type and the flat membrane structure allow for higher osmotic pressure.
Advantage 3: Long life.
The diaphragm is easy to clean, has a long service life, and is easy to maintain and replace.

Brands I've never heard of.
At present, there are many car film brands on the market, and the better brands are Northern Lights, 3M, Weigu, Ray-Ban, Quantum, etc., you can log on to the brand's official website to check, the jargon has "three points of film, seven points of process", the film is good and the process is good, this is very critical, you can compare and compare everywhere. Only regular authorized stores are qualified to operate authentic automotive solar films, and the promised warranty is guaranteed, which is generally provided by brand companies or manufacturers, and is definitely not a dealer, so you must pay attention! >>>More
1. Pay attention to regular sterilization equipment.
Usually DTRO disc tube reverse osmosis membrane can be a very small foreign matter or bacteria intercepted outside, so filtering water in this way is very clean, this point should also be noted that it can filter bacteria but not kill bacteria, so be sure to disinfect regularly, otherwise bacteria will accumulate and bacteria in the corresponding position too much will affect the filtration effect. Therefore, DTRO disc tube reverse osmosis membrane manufacturers should often carry out maintenance work in this regard. >>>More
When my home was just renovated, I didn't understand the use of glass film at that time, but also to save money directly bought online glass window film to the bedroom window pasted, used for about 3 months, the glass window blistered, ugly affect the beauty not to mention, when the sun is big, the film has a plastic smell, the room is slowly better after ventilation. Then I checked the harm of some inferior films on the Internet and suddenly realized it, and then there was an offline promotion of the glass film of the film customer at the entrance of the community, and I went to the field to test and experience the glass film of the film customer. Only then did I know that the glass film is used for so many purposes, not only for heat insulation and sun protection, but also for strong safety performance, as well as privacy protection function. >>>More
The new machine purchased will generally have a layer of disposable plastic film, which can be removed when used. When the mobile phone leaves the factory, the screen does not have a film, but please rest assured that the screen of the machine has been tested for scratch resistance before leaving the factory to prevent wear and tear within the normal operating range, and it will not affect the use without film.
