Five elements of how to maintain Beijing ultra-pure water machine

1. Activated carbon filter

The activated carbon filter mainly removes the odor and organic matter in the water through adsorption. There is residual chlorine in tap water, which has a great oxidation effect on the reverse osmosis membrane, so it needs to be removed by activated carbon. The activated carbon filter has no intuitive change on the surface. According to experience, it generally reaches saturation adsorption in about a year and needs to be replaced.

2. Use water

The ultrapure water machine that uses tap water as the water source generally has two water outlets, which are the third-grade water and the first-grade water. Immediately take, do not store. The tertiary water did not pass through the purification column, but the primary water passed through the purification column, and the cost of the primary water was higher than that of the tertiary water. Therefore, in daily application, customers should obtain water by quality according to water quality requirements, and try not to use first-grade water when third-grade water can be used, so as to avoid the increase in use costs.

3. Purification column

Purification column is sometimes called ultra-purification column according to customer's water quality requirements. The principle is ion exchange. The lifetime of the purification column is represented online by the resistivity. Below a certain resistance, it is intuitive that the purification column is expired. In addition to the customer's water consumption, its life is particularly important to the filling amount of the ion exchange resin and the quality of the ion exchange resin itself in the production design of each manufacturer.

4. Reverse osmosis membrane

The reverse osmosis membrane is a very important part in the ultrapure water machine. Its pore size is very small, so microscopic substances such as bacteria are often deposited on its surface during use. pollutants. If the water consumption is within 10 liters/day, it can be rinsed 3-5 times. If it exceeds 10 liters, rinse it several times. If it is not used for a long time (such as more than 1 month), it needs to be taken out and soaked in disinfectant to avoid the growth of bacteria, but the process is troublesome. The water forms circulation and minimizes the deposition of stagnant water for too long. The life of the reverse osmosis membrane is 2-3 years, which is mainly determined by the customer's water consumption, so the user must choose the matching specification when purchasing.

5. Precision filter element

Precision filter element, also known as filter element, wire wound filter element and pp meltblown filter element, mainly filter large particles such as sediment in raw water, and its filtration precision is 5 microns, 1 micron, etc. The new filter element is white. If the surface is silted and sandy for a long time, it will appear brown, which means that the filter element cannot be used. After washing the surface sludge with tap water, it can be used for 1-2 weeks, but it cannot be used for a long time. . The filter element is placed in the filter bottle. Some filter bottles are transparent, and the color change of the filter element can be observed intuitively. From the empirical data statistics, the life of the precision filter element is generally 3-6 months. If the raw water has more sediment, the life is shorter, and the sediment and other particles are less, the life is slightly longer.
