pre-filter precision how much better? Most people do not understand, look at the introduction of small series now.
prefilter belonging mains water purification products, an impurity filter, the filter may be 40-120 micron particle impurities to make the water to the water purification plant restore factory standards. It is generally installed after the house to meter a first exposed any previous tap water, water lines and wading equipment mounted on the pipe, such as water softeners, water purifiers, water machine or the like drink straight from the positive pre-protection. So much better precision prefilter?
The German authorities wading DVGW standard gas is involved, greater than 90 microns impurities can be easily removed by backwashing, but less than 90 microns minor impurities, even by backwashing too difficult to remove (along with a straight flush or rinse it simply can not be cleared), and small particles less than 90 microns in damage to the pipes and wading what equipment has not constitute. In addition, pre-filter only preliminary purification of water, kitchen water we will further installation of water purification equipment, so there is no need to risk prone to clogging of the prefilter, and improve filtering accuracy, as long as wading equipment not to harm. In this way, we only need regular ten seconds backwash can be.
through these presentations, I am sure you know how much precision pre-filter good knowledge of it. You also promise that you will ask: home pre-filter must be installed small advice you do not blindly, need to decide according to their own home water quality, water quality standard is actually based on what family does not need to drink small knowledge base?.
