Ultrapure water machine filter use daily note - 【 3 m filter.

Ultrapure water machine can remove the conductive medium is almost entirely in the water, and water dissociation of colloidal substance, gas and organic matter removal and low degree of water treatment equipment. Ultrapure water machine produces ultrapure water resistivity generally should be greater than 10 ohms, water is more than 10 ohms ultrapure water. General ultrapure water out of the water can reach 18. 25 ohms.

ultrapure water machine filter is with relative to the life of the material, so, in the use of ultrapure water machine has the following matters need to pay attention to:

1. Precision filter

the new filter is white, if time long surface alluvial sediment, etc, are brown, which means the filter can't use, use running water to rinse the surface sludge, may continue to use just 1 - 2 weeks, but it can't use for a long time. Filter in the filter inside the bottle, and some filter bottle is transparent, the color change of the filter can be observed visually, some filter bottles are opaque, needs to be unscrewed to observe the change of the filter element. The life of the statistic data from experience, the precision filter is in commonly 3 & ndash; In June, such as raw water sediment, its life is short, such as silt particles, is slightly longer service life.

　　2. Activated carbon filter

activated carbon filter, mainly through adsorption to remove the peculiar smell in the water, organic matter, etc. Chlorine in tap water, that you have great oxidation of reverse osmosis membrane, so must be removed by active carbon. Activated carbon filter on the surface without the change of the intuitive, according to the experience, general saturated adsorption in a year or so, need to change.

　　3. Reverse osmosis membrane

reverse osmosis membrane is very important parts in ultrapure water machine, its pore size is very small, so in the use process are often bacteria such as micro material deposition on the surface, rinse several times more. If long time ( If more than 1 months) No, needs to be soaked in disinfectant and avoid bacteria breeding, but the process is more troublesome, suggested that even if you don't water, often boot with a small amount of water, let the machine internal circulation of water, reduce water deposit time is too long. The service life of reverse osmosis membrane in 2 - 3 years, mainly determined by water, so must choose when choose the matched specifications.

　　4. Purification column

water quality purification column according to the customer's demand is also sometimes called super purification column, since the role is to deep desalting of reverse osmosis pure water, eventually reach the level of water or ultrapure water level. Its principle is ion exchange. The life of the purification column by resistivity online performance. Below a certain resistance indicates that the purification column expired, more intuitive. Its life in addition to the resistance to water, is especially important before and after each manufacturer in production when the design of ion exchange resin filling quantity and the quality of ion exchange resin itself.

　　5.

water with tap water as water source ultrapure water machine is generally has two outlet, the three levels of water and water level, it is reverse osmosis water level 3 water, stored in a tank, and water level is use namely, no deposit. Level 3 didn't pass the water purification column, level of water through the purification column, water level is higher than the cost of water level 3. So in daily application, should according to the water quality demand high quality water, as far as possible need not when can triple water level water, avoid the rising costs.
