1 CDI . technology
Till now, CDI . technology is the most advanced water purification technology in the world today with super absorption water purification technology. CDI technology applies electrolysis using electrodes to absorb dissolved ions such as metal ions, toxic substances, etc. in water.
The advantage of this technology is Filtering water to keep minerals, retaining more than 60% of minerals available in water, will help the human body absorb the necessary amount of minerals..
The special thing in This technology is that 90% of the water is retained in the filtration process, avoid wasting water resources that are gradually in shortage. At the same time, it also helps to prolong the life of the filter element, limiting damage or having to replace a lot during use.
In addition, the application CDI technology is suitable for diverse water sources, can filter even hard water with high hardness, well water, heavy metal ions,… including countries heavily contaminated with alum. In Vietnam, there used to be producer VietdreamTeach, Maxdream successful application of this technology on industrial and household scale.
Currently, a number of large food and pharmaceutical factories are applying water purifiers CDI . technology to ensure the water source for the production activities of the factory and the needs of the workers.
So, Water purifiers applying CDI technology are suitable for eating, living and production needs. CDI technology retains up to 90% of water, so the amount of water discharged into the environment will be very little contributing to reducing the current pollution.
This is a technology developed according to European standards with a membrane filter for water treatment according to the following mechanism: Mechanical filtration to remove large impurities; Absorption filtration by trapping toxic heavy metals in water; Ion exchange filter treats Ca2+ and Mg2+ components that cause water hardness; Filtration kills bacteria by killing bacteria in the water.
Filter technology Using natural pressure still retains the necessary minerals available in the water, while helping to save energy consumption.
In terms of disadvantages, for saline and brackish water sources, Nano filter cannot be fully processed. With water with a lot of sediment, Nano technology also requires a water softener or a water softener if treating water with a lot of sediment for a long time.
Without the water pretreatment steps, the Nano membrane will be easily damaged and need to be replaced regularly. These problems have not been fixed yet.
3 RO . Technology
RO technology is a reverse osmosis filtration technology that uses a semi-permeable membrane to remove substances other than water. The micro filter hole is only 0.0001 micrometer and the filtration process with strong speed (pressure) ensures the purest water source.
This also means that the minerals available in the water are completely removed.
On the downside, RO water purification technology has great limitations when it does not retain the necessary natural minerals for the body such as calcium, sodium, magnesium, water from this technology will cause the body to lack micro-organisms. quality and many other health problems if used for a long time.
The problem of power consumption of RO filtration technology is also mentioned, the system needs a pump to increase the flow pressure, potential risk of electric shock, pump fire when operating without water.
RO purifiers also emit 40-60% of water, which means that they can retain about 40% of water, quite a waste of water, the RO membrane is also easily damaged, and the cost is high when it is replaced.
Currently, RO technology is applied the reverse osmosis process in medicine, combined with a filter membrane with microscopic pores to produce 99% pure water quality. As a result, harmful bacteria can be removed and can be consumed directly without boiling. RO technology is suitable for many different water sources.
4 UV technology
This technology uses UV light to treat and remove the bacteria present in the water and the natural minerals are retained. However, UV rays only work with clear, colorless water.
The filter mechanism is simply understood that the water source passes through a steel chamber where UV rays are contained. Under the effect of UV rays, the bacteria lose their effectiveness and create a safe water source for use.
On the downside, the machine applying UV technology is said to be are not effective for dissolved impurities such as rust, pesticides, fluoride, arsenic, etc. Also, these purifiers are not effective for muddy water either.
UV filtered water also cannot be put into large tanks, which is quite inconvenient if you want to use it on a large scale, needing a continuous flow. At the same time, the input water still needs to be filtered before being treated.
5 UF . Technology
This is an ultrafiltration technology that is widely used in waste treatment, water filtration for beverage processing, etc.
UF technology works according to 2 principles:
- From the outside to the inside: that is, the filter layer is outside the filter, when the water is pushed into the impurities, the impurities will be retained outside.
- From the inside to the outside: that is, the filter layer is inside the filter, when the water flow is pushed in from the inside of the filter, the clean water flow is outside the filter.
One drawback The big part of this technology is that dirt, algae and bacteria will be trapped at the bottom of the filter cup. After a period of use, these substances will build up residue, causing blockage of the filter head, affecting water quality.
The above information helps us to have an overview of the water purification technologies being applied on the market today. Depending on the actual use needs, serving only for dining, living or on a large scale, industrial such as factories, production lines, users will decide which equipment to choose with which technology.
