Removes water-soluble dirt Dr. Do Huu Quyet, Center for Research and Deployment of High-Tech Park in Ho Chi Minh City, said that CDI is a Capacitive Deionization (CDI) capacitance technology, derived from the super absorption technology of supercapacitors. CDI water filtration technology has been certified to meet the standards at the TQC Quality Testing and Certification Center and meets the national technical requirements of TCVN 11978: 2017. “The development of supercapacitor technology in recent years has created electrodes that can store large amounts of electrical charge in their hearts. Applying the same principle, if one considers water a solution where 99% of the substances are electrolytes (including toxic substances, micronutrients, dissolved salts …), one can give a stream of Light electricity runs through the water. Use electrodes to absorb the dissolved substances from the water and store on the plate for the pure water to pass through. When the electrode is full of electrolytes, it can reverse the current to release harmful substances and use another small stream of water, causing the electrode to return to its original state. Under ideal conditions, the poles can be charged 1 million times while still retaining 80% of the performance. The discharge – charge properties are similar to the supercapacitors that the water filter elements can work continuously with a very long lifespan, up to 5 – 10 years, ”said Dr. Quyet. Drinking water must provide essential nutrients such as sodium, potassium, calcium, magnesium, iron, iodine, phosphorus … If only using purified water according to RO technology completely will lead to a lack of minerals. Super absorbent water filtration technology will create mineral water, kill bacteria, safe for health. Electrostatic CDI water purification technology can separate salt and water-soluble chemicals to create a drinking water source that ensures essential mineral levels, good for health. Safe water does not contain harmful toxins such as pesticides, fertilizers, heavy metals, cancer-causing oxidants, neutral or slightly alkaline pH, no harmful bacteria and delicious taste. The filtration system is designed like other water filtration systems, the only difference is that the CDI filter element is located just below the tap. The structure of the filter core is essentially a lot of electrodes combined together to absorb dirt. In the water, heavy metal components are immediately attracted to these electrodes. Meanwhile, the mineral components will be retained flowing through the membrane filter to the tap. In addition, the CDI filter element also has a micro ultrafiltration filter that removes suspended substances. Because water is circulated in the same direction with the filter, there is no tearing of the membrane, causing bacteria and toxic substances to escape. In addition to retaining minerals, filtering toxins, killing bacteria, CDI technology also has a high filtration efficiency when retaining 70 – 95% of water, the amount of wastewater compared to RO technology is much smaller (from 20-25 % compared with 50-70%). Especially, CDI filtered water always has air particles formed by minerals, tastes delicious, easy to drink … Due to the nature of the electrodes that will absorb toxins, users can adjust the amount of minerals at will by adjusting the electric current on the machine. Increasing the voltage to the highest level will produce the output water as pure water, decreasing with each degree, the mineral content will increase according to the needs of the user. Provide safe water for hospitals, schools Dr Quyet said the team’s future intention is to build large-capacity brackish water filtration systems integrated into water treatment plants in the West. Most of the provinces here do not have factories that can handle this problem. Traditional technologies have proved ineffective because they are expensive and fail quickly. Meanwhile, people often have to buy fresh water at the price of 50,000 – 100,000 VND / m3 during the salty drought. The essence of RO technology is to squeeze water through a filter to retain salt and obtain a stream of pure water, with both salt and water molecules too small to be easily pressed through the membrane, so the filtration process will requires great pressure and consumes a lot of energy. As a result, RO technology creates waste water flow up to 40% – 70%. Although RO wastewater can be used for purposes with less stringent standards such as irrigation, washing, washing … but other water purification technology developers are still striving to earn billions. clean water rates for living as high as possible in the same cost range. Because the operating principle of CDI technology is to “pick up” particles of salt and toxic substances out of the water stream, Dr. Quyet said that the amount of wastewater disposed of is only about 5-10%. According to Mr. Nguyen Thanh Tuan, Director of Vietdream Technology Co., Ltd, the goal of the business is to provide optimal, safe and effective water filtration solutions for users. The company does not sell water purifiers but only supplies filtration technology to partners with needs such as buildings, hospitals, schools, businesses using high standards of water, water purification plants. small and medium scale, enterprises producing food and beverages … With the co-founding of a technology company named Vietdream to commercialize this new water purification technology, Dr. Quyet hopes to “produce CDI water filters to replace RO filters”. Although the initial investment cost of CDI technology can be 2-3 times higher than RO technology, due to the difference in membrane life and operating cost, the overall cost of the first year of these two technologies are being equal. Currently, 70% of materials for Vietdream’s CDI water purification technology have been localized, including electrodes made from carbon nanotubes and polymers, water filtration modules and control systems. This trend could be reduced if they build more efficient supply chains or become widely accepted by the market.

Basket of spring rolls is pre-fried to store and freeze – Nem just taken out from the freezer will stick slightly together, lightly beat the box 2-3 times to make the spring roll out of stick. – Pour oil into the pan and heat it up. – Put the spring rolls in and fry it in low heat to make it hot inside. – Cooked spring rolls on a plate. Nem is taken out of the frying freezer as well, no need to wait for defrosting Illustration. Fried spring rolls – Fry the spring rolls 2 times, after the spring rolls are finished, women proceed to fry them to make 2 times of oil. The first time, heat the spring rolls over low heat, then cook the spring rolls and fry it, then take them out to absorb the oil blotting paper. After the first round of frying, women can replace the new oil and fry the spring rolls to fully ripen and the crust will be golden, crispy beautifully.When the second frying, we should use cold fat to fry, avoid blistering. nem. – You can mix a bowl of dilute sugar water, use a soft brush, spread a layer of mild sugar water on top of the rolled-up spring rolls and start frying on a low heat pan. Nem will then be crunchy. – Before putting the filling in spring rolls, use a damp cloth to wipe the rice paper and apply a little bit of beer or vinegar, then pour the filling into the roll. This way to ensure crispness and a nice spring color. -Put in the fridge before frying, many women share experiences, the spring rolls are not ready to fry immediately, but to keep the fridge cool for about 20 minutes to make the rolls tight, dry and deep-fried. – Deep frying (should use a deep pan, or a small pot will save more oil). When you add the oil to the pan, add a few drops of lemon juice. Next, boil the oil and fry it as usual. If you put lemon juice in the first place, no shot will be done during frying, and the spring rolls are crispy. – If you make a lot of spring rolls but have not been able to eat them immediately because you wait for guests (or at the wedding, anniversary …), after frying, you need to take out a paper to absorb oil, otherwise the remaining cooking oil in the spring rolls will absorb back. come back, make spring rolls crunchy. – Roll the spring rolls not tightly: When wrapping the spring rolls, women pay attention not to wrap them too tightly, this will cause when fried spring rolls, the inside of it will expand a little, the cake will be torn, the kernel will reveal its aesthetic. . Only a moderate amount, maybe a little loose hand. Some note: – It is recommended to use the ramen shells so that spring rolls are not crushed and still crispy after freezing. – Should make spring rolls small and fit. Crispy fried spring rolls, hot, even if kept frozen for a month – Nem removed from the freezer and put it in the frying pan, no need to defrost. – In a spring roll, you can add 2 purple onion branches to make it fragrant.

Step 1: Please put clean water in a pot or a clean bowl. Next, add 1 teaspoon of salt and a few drops of white vinegar, stir to dissolve.

Step 2: You put the frozen meat in, soak it for 5-7 minutes, you will see the meat soften gradually, helping the food to thaw, fresh and delicious meat makes your dish more attractive.

Effective thawing

Step 3: When you want to thaw meat, remember to put the 2 ingredients salt and vinegar in the broth, they both help to remove bacteria, but also make the meat soft quickly, the taste of the meat is also more attractive.

Microwave the meat

One of the safest and effective ways to defrost it is by microwave it. Proper thawing will prevent the meat from multiplying by exposure to room temperature, which can lead to poisoning and diarrhea. In addition, to allow food to defrost easily, you should put meat in a ceramic bowl or glass bowl should not be placed in easily contaminated plastic.

Using salt and vinegar helps to defrost meat quickly

Thaw meat in the refrigerator cooler

If you have time you can find a way to slowly thaw meat in the refrigerator cooler, which is commonly used by many housewives, if you intend to prepare a dish with frozen meat, you should remove the meat from the freezer. Down the refrigerator compartment overnight, so that the meat can slowly thaw to help soften the meat when women can easily process them into effective dishes.

Specifically, speaking before the meeting of the Defense Sub-Committee of the European Parliament in Brussels – Belgium, Andrii Taran noted that he could not rule out the possibility that Russian forces in Crimea could “take provocative actions. military promotion “in 2021.

Earlier, Mr Taran said “Russian provocations” could exacerbate conflicts in the Donbass region of eastern Ukraine bordering Russia. Taran revealed that Russia concentrates 110,000 troops on the Ukrainian border.

According to Reuters, any decision by Russia to move nuclear weapons to Crimea will be a bad development in East-West tensions. That gesture would increase tensions for a newly renewed arms control treaty between the US and Russia.

Concerning developments, in a statement from the Ukrainian army, the Ukrainian armed forces have been rehearsing to increase their ability to respond to a tank and infantry attack near the Crimea border on April 14. The drills come the day after US President Joe Biden phoned Russian President Vladimir Putin to discuss Russia’s military build-up near eastern Ukraine and in Crimea.

On the Russian side, on April 14, the Russian navy began exercises in the Black Sea with exercises to fire targets on the ground and in the air. This exercise is to test combat readiness, readiness to react to threats from NATO. As planned, the rehearsal would end after 2 weeks.

First of all, mothers prepare, clean and chop food.

Then cook food by steaming, boiling … Steaming is a method of processing food that helps retain the most nutrients.

Put the food in the machine and puree or finely sieve, mothers can add boiled vegetable juice, breast milk, formula or water to grind or sieve together to loosen the mixture.

Note, when preparing snacks for babies, mothers should not add salt and sugar.

How to preserve weaning food

After grinding and grinding the food into a liquid, the mothers will pour them into a mold and store them in the freezer for freezing.

Cover the mold with plastic wrap or the lid included with the tray and store in the freezer.

When the pellets were frozen, mothers took them out and put them in a zip bag.

Note, do not leave food in the refrigerator for too long. Only use frozen food for 1 week for best results.

You also need to note that you must regularly clean the refrigerator to remove bacteria in it. The temperature of the refrigerator must be kept stable, limiting the opening and opening continuously because it will easily spoil the food.

How to thaw food weaning

When needed, the mother takes the necessary amount of food on a plate, wrapped it and put it in a cool compartment overnight.

Another way to thaw faster is to place a sealed bag of frozen food in warm water, which can be changed if needed. Or take out the food from the ice tray and place it in a ceramic bowl and cook in a water bath.

If you have a microwave, you can use it to heat your child’s food. Thaw in the microwave for the allotted time. Stir and stir regularly, making sure the food is completely thawed before serving.
