What Is The Use Of Briefly Introducing The Maintenance Cycle Of Three Types Of Filter Elements Of Ultra-pure Water Machine?

Ultrapure water machines are roughly divided into four units: pretreatment, reverse osmosis, ion exchange and terminal ultrafiltration. Tap water first passes through a pretreatment device to remove larger particles, suspended solids and some organic matter in the water. Then it enters the reverse osmosis device to intercept and remove ionic substances and macromolecular substances (such as viruses, microorganisms, etc.) in the water. Afterwards, the ion exchange unit purifies and ultra-purifies the trace ions remaining after membrane removal, reducing the ion content in the water to trace levels. Finally, through ultraviolet and ultrafiltration technology, microorganisms, organic matter and pyrogens in ultrapure water can meet the requirements of various experimental applications. The stable operation of the ultrapure water machine requires keeping the performance of the systems at all levels in good condition. The ultrapure water machine adopts a multi-stage filtration mode. This increases the cost of using the ultrapure water machine. Here is a brief introduction to the approximate service life of each filter element.

1.PP cotton filter element
Primary filtration of raw water mainly filters particles larger than 5u, such as sand, rust, rust, sludge, phosphorus pollution, slag, etc. Service life: 3-6 months. It is generally recommended to replace it once every 3 months in summer and every 6 months in winter.
 

2. Coconut shell activated carbon filter element
It absorbs residual pesticides, fertilizers and other pollutants, ultimately rendering the water colorless and odorless. Service life: Replace once every 3-6 months.
 

3.Micro PP filter element
It mainly filters particles and impurities with a diameter larger than 1u. Service life: 3-6 months.
