Two-level reverse infiltration problem
Secondary reverse infiltration was a technique that used pressure to force water molecules to pass through a reverse infiltration membrane that had a selective permeating effect on water molecules. According to the different osmic pressures of various materials, the device can separate, extract, purify, and concentrate by reverse infiltration, which is greater than the osmic pressure. It can remove more than 98% of the dissolved salt and more than 99% of the colloid, microorganisms, particles, and organic matter in the water. It is the best equipment for modern pure water and space water (ultra-pure water) projects. The second-stage reverse infiltration equipment consisted of a two-stage Reverse Osmosis device, a cleaning system, and a middle water tank. In the operation process, the raw water was first sent to the pre-treatment system for rough filtering, and then filtered by the precision filter. After being sent to the first-stage reverse infiltration system by the first-stage high-pressure pump, the water produced by the system was then sent to the second-stage reverse infiltration system by the second-stage high-pressure pump to produce product water (pure water).

Level 2 reverse infiltration plus edi high purity water system
The two-stage reverse infiltration and edi high-purity water system was a high-efficiency pure water production system. In terms of pre-treatment, raw water (such as tap water, underground water, river water, etc.) first went through pre-treatment equipment such as a Quartz Sand filter, an activated carbon filter, etc. The purpose was to remove suspended solid, colloid solution, particles, and other substances in the water to provide qualified water for the subsequent reverse infiltration device. For the secondary reverse infiltration part, when the raw water TDA is greater than 300pm, the secondary reverse infiltration system can be used. The feed water's pH should be controlled between 8.5 - 9.0. When adding NaOH into the feed water, pay attention to the LSI value of the reverse infiltration concentrated water to prevent scaling. The water after the first level of reverse infiltration was further filtered by the second level of reverse infiltration. In the EDI module, generally, the secondary reverse infiltration (RO) pure water was used as EDI feed water. EDI sandwiched ion exchange resin between the negative and positive ion exchange membranes to form EDI units. Driven by direct current, the positive and negative ions in the water flow through the freshwater chamber passed through the negative and positive ion exchange membranes and entered the concentrated water chamber to remove ions in the freshwater chamber. The water in the concentrated water chamber carried the ions out of the system to become concentrated water. During the EDI process, there was no need for regeneration and no acid or alkali-free waste water was discharged. The production would not be affected by the regeneration, and the quality of the produced water would be more stable. The electrical resistance of EDI pure water can be as high as 18M Omega.cm(25 ° C), which is suitable for the preparation of pure water with electrical resistance requirements of 1 - 18.2 M Omega.cm(25 ° C). In the entire system, various parts worked together, such as the 20 tons/hour secondary reverse infiltration +EDI ultra-pure water equipment system, which included the pre-treatment part, the secondary reverse infiltration part, the EDI part, the 18M water supply part, etc. Each part was placed in the water station and operated under the control of the PC. The control system of distributed control and concentrated monitoring was used to ensure the water quality and quantity of ultra-pure water. Throughout the entire process, the daily tap water first entered the original water storage tank. After a series of treatments, it was filtered through the secondary ro reverse infiltration and entered the EDI module and the polishing mixed bed module. The EDI produced water entered the high-purity water storage tank, and then after subsequent treatment, it reached different electrical resistance requirements and was sent to the water point. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

On-line chemical cleaning of reverse infiltration materials
The following are the relevant points for online chemical cleaning of reverse infiltration materials: ** 1. Determination of the time to purge ** When the standardized pressure difference between the feed water and the concentrated water increases by 15%, or the standardized water yield decreases by 10%, or the standardized salt penetration rate increases by 5%, the membrane system should be cleaned. If the cleaning was delayed for too long, it would be difficult to completely remove the dirt and restore the membrane performance to its original state. ** 2. Determination of dirt type ** 1. ** Determination by chemical analysis ** - It was best to conduct a chemical analysis of the residue collected on the PDI test membrane to determine the main type of contamination, so that targeted chemical cleaning could be carried out. 2. ** Indirectly Judgement Method ** - When chemical analysis is not possible, the dirt can be classified according to the determination of the PDI, the color and density of the residue on the test membrane. For example, brown residue may be iron dirt; white residue may be silicon, sandy clay, calcium dirt, etc.; the shape of the crystalline lens may be the characteristics of an organic colloid or calcium dirt; biological or organic dirt, except for odor, is usually sticky. ** 3. Cleaning Program Selection ** 1. ** Against Metal Hydride or Calcium-scale ** - If the dirt is a metal dioxide (such as iron dioxide) or calcium dirt, it can be cleaned with lemon acid. 2. ** Against organisms or microorganisms ** - If it is determined that the main dirt is organic matter or microorganisms, it is recommended to use an acidic cleaning method. ** IV. Selection and conditions of chemical cleaning agent ** 1. ** Potion selection ** - ** Inorganic salt scale (e.g., calcium scale)**: 0.2% HC1 solution (pH1 - 2, temperature <38 ° C) is preferred. 2.0% Citric acid (best to soak overnight), 1.0% Na Chi S Chi O, 0.5% Phosphorous acid are also available. - ** Metal Oxides (such as iron, aluminum, etc.)**: 1.0% Na ^S ^O ^solution (temperature <35 ° C) is preferred, 0.5% phosphorous acid and 2.0% lemon acid are available. - ** Acid Invisible Scale (CaF <2>, BaSO2 <3>, SrSO2 <3>, CaSO2 <3>)**: 0.1% NaOx solution +1.0% Na <3><4><4></4><4><5 <4><5 <5><5 <5><5 <5> - ** Inorganic colloid (such as sludge)**: 0.1% NaOx solution +0.025% Na-SSS (pH11 - 12, temperature <30 ° C). - ** Silicate scale **: 0.1% NaOx solution +0.025% Na-SSS (pH11 - 12, temperature <30 ° C; you can also choose 0.1% NaOx solution +1.0% Na Cu </anno> solution). - ** Microorganism **: 0.1% Na-Na solution +0.025% Na-SSS (pH11 - 12, temperature <30 ° C; 0.1% Na-Na solution +1.0% Na-Se solution can also be selected). - ** organic matter **: 0.1% Na-Na solution +0.025% Na-SSS is usually used as the first step of cleaning (pH11 - 12, temperature <30 ° C; 0.2% HClsolution is usually used as the second step of cleaning after the basic cleaning). 2. ** Cleaning conditions ** - ** Water for configuration **: Softened water or product water, free of heavy metals, residual chorine or other oxidisers. - ** Drug dosage **: Each 8-inch element: 40 - 80 liters (depending on the degree of dirt); Each 4-inch element: 10 - 20 liters (depending on the degree of dirt). - ** Operating pressure **: Lower pressure (0.1 - 0.3MP), usually no more than 0.4MP. - ** Cleaning flow rate **: 6 - 9 m3/hr for each 8-inch pressure vessel; 1.8 - 2.3 m3/hr for each 4-inch pressure vessel. - ** Cleaning fluid temperature **: As high as possible, but the highest temperature is 45 ° C. Usually, 30 - 35 ° C is selected. If it exceeds 45 ° C, cooling equipment should be installed. - ** Cleaning Type **: Each pressure vessel is to be recycled and soaked in turn. - ** Cycle Time **: It is recommended to repeat every 0.5 - 1 hour (2 - 3 times). - ** Soaking time **: 2 - 24 hours (depends on the degree of dirt). - ** Cleaning method **: It is best to clean it in sections. - ** Cleaning time **: At least 1 - 2 hours, depending on the degree of contamination and the cleaning method used. ** 5. Cleaning effectiveness assessment ** Following the recommended cleaning method, the pressure difference of the entire membrane system will usually be reduced to the initial value, and the water production flow rate and rejection rate will be restored. If the system performance does not improve sufficiently after cleaning, other recommended methods are recommended. In many cases, several consecutive cleaning methods were needed to remove membrane contamination, and alternating cleaning agents were more effective than using a single agent. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the factors of reverse infiltration membrane pollution?
The main reasons for the reverse infiltration membrane's organic pollution were the blockage of the membrane surface and the inner pore size caused by the crystal structure of calcium, silicon, phosphorus and other organic salt. The influencing factors were as follows: - Physical factors: Crystallization. Some metal ions in the feed solution, rinsing water, and unreasonable cleaning agents will be crystallized on the micro-pore interface during the operation of the membrane. When the microscopic concentration exceeds its saturation concentration, crystallization will occur. Due to the existence of concentration difference, crystallization generally occurs near the membrane surface. The quality of the rinsing water, the stickiness of the cleaning agent, the performance of the rinsing water, and the contact conditions between the cleaning agent and the dirt in the feed liquid would all affect the residual crystallizable metal ions and the formation speed and volume of the formation of the organic scale. - "chemical factors: Any form of existence (including organic forms) in the calcium, ion liquid or rinsing water will remain in the membrane pores that have almost no scouring mechanical force to varying degrees. The raw material used for traditional cleaning, the base, has high stickiness, poor water conductivity, and a long cleaning time. This provides sufficient conditions for the formation of the crystalline structure of calcium and carbonates." If such crystals were formed inside the membrane pores, they would cause the membrane pores to be blocked. Moreover, they would be very tightly bound to the membrane material. Unless special methods were used, it would be difficult to regenerate them. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the technical characteristics of reverse infiltration membranes?
Reverse Osmosis membranes have the following technical characteristics: 1. ** High rejection rate and high flux **: This is an important manifestation of the performance of the reverse infiltration membrane. It can effectively remove dissolved salt, colloid, microorganisms, organic matter, etc. in the water. The removal rate can reach 97% - 98%. The pore size of the membrane is very small (only about 10A), and it has a very fine pore structure. It can only filter out substances with a molecular size of less than 1 nano, so as to remove harmful substances in the water to the maximum extent and achieve efficient purification of various water indicators. 2. ** Good physical properties ** - ** High flow rate must have high rejection rate and water yield **: Under the condition of high flow rate, it can still guarantee a good rejection rate and a high water yield. - ** High mechanical pressure resistance and service life **: Able to withstand a certain amount of pressure and has a long service life. - ** Able to function under low pressure **: Normal filtering work without high pressure. 3. ** Chemistry stability ** - ** Oxidation-resistant **: Able to resist the effects of oxidization and ensure the stability of the film. - ** Acid and Alkaline Resistance **: It is less affected by the ph value and can work in different acid and alkali-based environments. - [Resistance to the influence of chemicals and organisms: Resists the influence of chemicals and organisms in the water and is not easily destroyed.] - [Heat Resistance: Able to maintain stable performance within a certain temperature range.] 4. ** Anti-blockage, Durable **: It is a strong and anti-blockage membrane that can resist water pollution and prevent blockage on the surface of the membrane. It has high durability, long operation time and low maintenance costs. 5. ** Protective features ** - ** No secondary pollution **: The filtering process is naturally non-polluting. It does not require the use of any chemicals, reducing the secondary pollution that may be caused during use. It will not release any toxic, cancerous, and other harmful substances to ensure the purity of the water. - ** Energy Saving and Pollution Reduction **: Compared with the traditional water treatment process, it can save energy to a greater extent and reduce carbon dioxide discharge, because only one pressure pump is needed to filter the water, which does not require a lot of power consumption. 6. ** Easy access to raw materials and low processing costs **: The raw materials for manufacturing the film are easy to obtain, easy to process, and low in production costs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Dongying City single-stage reverse infiltration
The single-stage reverse infiltration equipment in Dongying City had different applications in different scenarios. The single-stage reverse infiltration equipment realized water purification through a single membrane component. Its rejection rate was low, but its structure was simple and its maintenance cost was low. It was widely used in the drinking water purification field of households and small commercial places. In Dongying City, if the demand for water was not high, such as the demand for household drinking water, single-stage reverse infiltration equipment was a good choice. In addition, there were also related single-stage reverse infiltration equipment supplies in Dongying, such as the Dongying Zhiyue reverse infiltration 7-inch static single-stage industrial machine pure water machine controller, priced at 680 yuan per unit. However, if it was in the industrial field, especially in industries with high water quality requirements, such as process water/chemical circulating water in the textile and chemical industries, chemical product manufacturing, food and beverage industry water, beverages, beer, white wine, health care products, etc., the double-stage reverse infiltration equipment was more suitable. The single-stage Reverse Osmosis membrane was mainly used to remove dissolved salt, organic matter, silica colloid, and molecular substances in the water, as well as the dosage agent in the pre-treatment. If the EDI module was needed after the single-stage Reverse Osmosis, the raw water quality must be quite good. If the EDI module was directly added to the single-stage Reverse Osmosis, the load of the first-stage Reverse Osmosis treatment would be large, and the quality of the produced water would be poor, which might cause EDI to be paralyzed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
