What are the precautions for the use of DTRO disc tube reverse osmosis membrane in the filtration sy

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.

2. Pay attention to membrane permeability.

In order to make the filtration system achieve good results, some corresponding coefficients should be measured and calculated in advance, and then the corresponding number of DTRO disc tube reverse osmosis membranes can be reasonably configured and selected, so that the corresponding amount of water can be cleaned within the specified time.

3. Pay attention to the protection of instruments and equipment.

In general, the relevant parts of the DTRO disc tube reverse osmosis membrane are very fine and cannot be collided, so they must be handled with care when in use, and the storage should also be stored in a special box to avoid damage, and the installation should also be done carefully.

DTRO membrane (disc tube reverse osmosis membrane) is a form of reverse osmosis, which is a membrane module specially designed to treat high concentration of sewage, and its core technology is 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.

Two-stage DTRO treatment system, including first-stage control system, sand filter, first-stage reverse osmosis system, second-stage reverse osmosis system, leachate storage tank, sulfuric acid storage tank, water purification storage tank, cleaning agent storage tank, degassing tower, etc. The disc tube reverse osmosis system is the core part of the disc tube membrane column, which is composed of a disc RO diaphragm, a deflector plate, an O-shaped rubber gasket, a central tie rod and a pressure-resistant sleeve. The diaphragm and the deflector plate are stacked at intervals, and the O-shaped rubber gasket is placed in the groove on both sides of the deflector plate, pulled together with the center, and placed in the pressure-resistant sleeve, and the two ends are sealed with metal end plates.

(1) The effluent quality is good. DTRO membrane has a good retention effect on refractory organic matter and other ammonia nitrogen compounds. The stable and thorough interception of substances such as high COD and heavy metals makes DTRO membrane technology irreplaceable in the application of seawater desalination, high COD, garbage and wastewater treatment, acid-containing wastewater, etc.

2) Occupy less space. The DTRO membrane system is an integrated installation, and the ancillary structures and facilities are also small structures, which occupy a small area and save the application space.

3) Minimal chemical handling costs. The traditional treatment process generally requires a large amount of chemicals for the precipitation of suspended solids in the early stage, while DTRO membranes only need a small amount of chemicals in the work.

4) Simplify the water treatment process. DTRO membrane technology is simple to operate and maintain, does not rely on pretreatment in operation, only needs to carry out simple pretreatment, and is easy to realize automatic control and management. **Yantai Jinzheng environmental protection.

1.High concentration of industrial wastewaterMany industrial industries, including electric power, pharmaceutical, petrochemical and steel smelting, will produce a large amount of wastewater in the production process, and the concentration of organic matter in the wastewater is still very high, if it is directly discharged, it will cause great harm to the environment, and the cost of other membrane technologies will be very high.

2.landfills as wellIncineration site.

The garbage generated in life and production must be transported to a special landfill or incineration site for treatment, but after the disposal of this garbage, landfill leachate will be produced, which will become the main culprit of polluting surface water, groundwater, soil and ecological environment because it contains a large number of high-concentration pollutants. DTRO tubular reverse osmosis membranes are effective in filtering landfill leachate and can therefore be used in landfills and incineration plants.

3.Kitchen wastewaterThe restaurant will use a lot of oil in the cooking process, so the discharged kitchen wastewater often contains a high concentration of humic acid, which will also cause serious damage to the soil and groundwater.

DTRO disc tube reverse osmosis membrane element has the characteristics of simple pretreatment, low influent water quality requirements, high ** rate, and high desalination rate. With the rapid development of membrane technology, what are the precautions when we purchase DTRO disc tube reverse osmosis membrane elements?

1. Product performance factors.

Due to the different application environments, it is necessary to take the lead in understanding the performance characteristics of the membrane element products and the disposal environment, and analyze the basic parameters of the DTRO disc tube reverse osmosis membrane element and its anti-fouling ability to objectively understand the basic properties of the membrane element. Therefore, when selecting DTRO disc tube reverse osmosis membrane elements, it is necessary to understand the membrane flux and its anti-fouling effect, and the corresponding life and filtration range also need to be comprehensively analyzed to ensure the product quality of DTRO disc tube reverse osmosis membrane elements.

2. The use effect of the product and the subsequent cleaning needs.

In the long-term application, the follow-up replacement, maintenance and cleaning work is the focus of attention, and only with a simpler cleaning process and better replacement and disposal methods as the foundation, can the utilization efficiency of the DTRO disc tube reverse osmosis membrane element be improved.

DTRO disc tube reverse osmosis membrane elements have the characteristics of long service life, easy maintenance, and low replacement cost of filter membranes, so they have been recognized by many users.

In general, there are three aspects that need to be paid attention to: desalination rate, water yield and specifications.

1. Select according to the water production.

Water yield refers to the amount of water permeable to the RO reverse osmosis membrane per unit time after the use of the reverse osmosis system. Therefore, when choosing the model of RO reverse osmosis membrane, we should pay attention to this parameter of the selected membrane type, and also consider the actual water demand.

2. Select the type according to the size and specification of the membrane element.

This is mainly due to the design of the reverse osmosis equipment system, if the reverse osmosis system is designed with a 4-inch membrane, then only a 4040 specification reverse osmosis membrane can be selected, if it is an 8-inch or other size membrane shell, then it is necessary to choose the appropriate model or replace the membrane shell.

3. Select the type according to the desalination rate.

The denser the desalination layer on the surface of the RO reverse osmosis membrane, the higher the desalination rate, but because the desalination rate of the RO reverse osmosis membrane has been determined at the time of manufacturing, we should fully understand what the selected membrane desalination rate is when purchasing the RO reverse osmosis membrane model, and what the desalination rate is required, and select the type according to the matching between the two.

4. Select the model according to the best rate.

The rate is the percentage of water converted into permeate or permeate, and the rate is based on the quality of the pretreated influent water in the reverse osmosis system, and the water use requirements. Therefore, if you want to buy the right RO reverse osmosis membrane model, you must fully understand the larger and smaller, how much the best rate can reach, and whether it can meet the needs of the enterprise for the use of produced water.

What are the precautions for the purchase of DTRO disc tube reverse osmosis membrane elements?

1. Performance factors:

When selecting DTRO disc tube reverse osmosis membrane elements, users need to understand the membrane flux and its anti-fouling effect, and the corresponding life and filtration range also need users to conduct a comprehensive analysis to ensure the quality of DTRO disc tube reverse osmosis membrane element products.

2. Use effect and follow-up cleaning needs:

Only with a simpler cleaning process and a better replacement and disposal method as the basis can the utilization efficiency of the DTRO tubular reverse osmosis membrane elements be improved. Therefore, users need to know the follow-up cleaning of the DTRO tubular RO membrane element to ensure that the DTRO disc tube RO membrane element can be repaired quickly.

1.The pressure-resistant diaphragm structure of the bag center opening, with a flexible clean water diversion diaphragm in the middle, can withstand a pressure of more than 60 bar and still ensure the operation of the reverse osmosis membrane, which can achieve a high clean water rate of high salt content.

2.The wide flow channel has a channel of 2mm between the diaphragms, while the reel-encapsulated membrane module has only one, and the wide flow channel is less likely to be blocked by contaminants.

3.The short process of liquid on the surface of the membrane is only 7cm, while the membrane module of the roll encapsulation is 100cm, and the short process can reduce the occurrence of the concentration polarization of the concentrated reverse osmosis membrane, and the surface of the membrane is not easy to scale.

4.Turbulence, high flow velocity of fluid design, Reynolds number greater than 2000 units, the fluid forms a tumbling high-speed turbulence, under the erosion of this turbulence, the membrane surface is not easy to settle pollutants. In reel-encapsulated membrane modules, the mesh scaffold retains contaminants and is more susceptible to diaphragm contamination.

These four characteristics determine that the disc tube reverse osmosis technology can withstand high suspended solids and SDI when treating high-salt and high-concentration sewage such as landfill leachate (generally reverse osmosis requires SDI not to be higher than 5, while the disc tube reverse osmosis system can reach 20), in layman's terms, it will not form a blockage.

Technical characteristics of DTRO disc tube reverse osmosis membrane.

1. Avoid physical blockage.

2. The open flow channel design is adopted, and the effective flow channel of the material liquid is wide, which avoids physical blockage.

3. Low degree of scaling and pollution.

4. Using the deflector plate with convex support, the material liquid forms a turbulent state during the filtration process, which greatly reduces the fouling, pollution and concentration polarization phenomenon on the membrane surface, and allows the highly polluted water source with an SDI value of up to 20 without the risk of being polluted.

5. The membrane has a long service life.

At the same time, the special structure and hydraulic design of the DTRO reverse osmosis membrane make the membrane pack easy to clean, and the flux recovery after cleaning is very good, thus prolonging the life of the diaphragm.
