Ultra-pure water equipment is mainly filtered through four categories: precision filter element, activated rural drinking water equipment carbon filter element, reverse osmosis membrane, etc. Both of them have relative life. Precision filter and activated carbon filter are actually the protection of reverse osmosis membrane. If they fail, the load of reverse osmosis membrane will increase and the life of reverse osmosis membrane will decrease. If the power is continued, the quality of pure water will decrease, which will aggravate the negative of reverse osmosis school drinking water equipment permeation membrane. The life of reverse osmosis membranes will be shortened if they are loaded. The final result is to increase the cost of ultra-pure water equipment.

Therefore, matters needing attention in the use of ultra-pure water equipment

1. Precision filter element is mainly used to filter sediment and large particles in water. The filter element of the new ultra-pure water treatment equipment is white and will turn brown after a long time. The reason is that the sediment deposited on the surface of the filter element. This shows that the filter element is no longer available and needs to be replaced as soon as possible.

2. Activated carbon filter can remove odor and residual chlorine in water. Generally, activated carbon should be replaced once a year, because the total surface of activated carbon can not be seen to change.

3. Reverse osmosis membrane is a very important component in ultra-pure water equipment. The life of reverse osmosis membranes is usually 2-3 years.
