Millipore MILLIPORE ultra-pure water machine water quality and water consumption have a significant impact on filter life

The filter of the pure water machine has a long life. Many households do not remember to change the filter after purchasing the pure water machine, and the filtered water may fail due to failure or dirty plugging of the filter function.

Although many filter cartridges indicate that the service life is 3 months or half a year, the quality of the water has a significant impact on the life of the filter. For example, PP cotton, activated carbon, KDF filter material, etc., the tap water quality is good, maybe half a year, if it is not good, it may only take 3 days. Even filter cartridges that can be drained, such as ultrafiltration membrane cartridges, different manufacturers, and different technologies, result in huge differences in filter life. Ultrafiltration membranes that are widely used by professional manufacturers in industrial water treatment are more trustworthy.

Glassware washing machine

If an ultra-pure water machine uses a filter element such as PP cotton or activated carbon, and there is no sterilization function to protect the filter element, it is easy to become a breeding ground for bacteria. In order to avoid the secondary pollution of the pure water machine, the pure water machine must have the sewage function, and the last filtration should be able to filter out the bacteria.

MILLIPORE ultra pure water machine notes:

Precision filter

The precision filter element, also known as the filter filter element, the split-line wound filter element and the PP melt-blown filter element, mainly filters large particles such as sediment in the raw water, and the filtration precision is 5 micrometers and 1 micrometer. The new filter element is white. If the surface is long, the surface will be silted, etc., and it will appear brown. This means that the filter element can not be used. After washing the surface sludge with tap water, it can barely continue to use for 1-2 weeks, but it cannot be used for a long time. . The filter element is placed inside the filter bottle. Some filter bottles are transparent. The color change of the filter element can be visually observed. Some filter bottles are opaque and need to be unscrewed to observe the change of the filter element. From the empirical data statistics, the life of the precision filter element is generally from March to June. If there is more sediment in the raw water, the life is shorter, and the sediment and other particles are less, the life is slightly longer.

2. Activated carbon filter

The activated carbon filter mainly removes odors and organic substances in the water by adsorption. There is residual chlorine in the tap water, which has a great oxidation effect on the reverse osmosis membrane, so it must be removed by activated carbon. There is no intuitive change in the surface of the activated carbon filter. According to experience, it is generally saturated in a year or so and needs to be replaced.

3. Reverse osmosis membrane

The reverse osmosis membrane is an important part of the ultra-pure water machine. Its pore size is very small. Therefore, microscopic substances such as bacteria are often deposited on the surface during use. Generally, the pure water machine of each manufacturer has a backwash function. Wash off the contaminants. The water consumption can be washed 3-5 times within 10 liters/day. If it exceeds 10 liters, it should be washed several times. If it is not used for a long time (such as more than 1 month), it needs to be taken out and immersed in the disinfectant to avoid the breeding of bacteria. However, the process is troublesome. It is recommended that even if it is not used, it is often turned on with a small amount of water to allow the inside of the machine. The water forms a circulation, and the deposition time of the dead water is minimized. 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 specifications when purchasing.

4. Purification column

The purification column is sometimes called ultra-purification column according to the customer's water quality requirement. The self-acting is deep desalting of reverse osmosis pure water, and finally reaches the level of first-grade water or ultra-pure water. The principle is ion exchange. The lifetime of the purification column is represented by the resistivity online. Below a certain resistance means that the purification column has expired and is relatively intuitive. In addition to its anti-customer water consumption, its life is especially important for the amount of ion exchange resin and the quality of the ion exchange resin in each manufacturer's design.

5. Water

Ultra-pure water machines with tap water as the water source generally have two outlets, namely three-stage water and first-grade water. The water that is reverse osmosis is three-stage water, which is stored in the water tank, and the first-stage water is ready to use. Take it, don't store it. The tertiary water does not pass through the purification column, and the first stage water passes through the purification column, and the cost of the first stage water is higher than that of the third stage water. Therefore, when customers use it in daily use, they should take water according to the water quality requirements. When using the third-grade water, try not to use the first-grade water to avoid the rising cost.

The MILLIPORE ultra-pure water machine is noisy:

Check whether the raw water pipeline is broken, causing the booster pump to idle, resulting in a loud noise of the pure water machine;

Check whether the raw water is normal, if there is no tower water supply, whether there is gas in the water;

Check if the booster pump is faulty, the vibration is too large, there is friction, etc.;

Check if the pure water machine is placed firmly;

Check if the water pipe is too long, and the vibration of the pump causes the water pipe to hit the casing;

Check if the hot water is boiling and causing excessive noise;

Check if the compressor is normal.

Food And Beverage Additives

Food additives refer to chemically synthesized or natural substances added to food in order to improve the quality, color, aroma and taste of food, as well as for the needs of antiseptic and processing technology. Due to the rapid development of the food industry, food additives have become an important part of the modern food industry, and have become an important driving force for technological progress and technological innovation in the food industry. In the use of food additives, in addition to ensuring that they play their due functions and roles, the most important thing is to ensure the safety and hygiene of food.
