The 0.1\u03bcm PVDF ultrafiltration Membrane and 0.01\u03bcm PVC ultrafiltration membrane<\/strong> are two common membrane types used in ultrafiltration water purifiers<\/a><\/strong>. They differ in membrane material, filtration precision, filtration structure, cleaning method, and application scenarios.<\/p>\n\n\n\n

For ultrafiltration water purifiers<\/strong>, the membrane material and filtration precision directly affect the type of impurities that can be intercepted and the suitable water purification application. In general, a 0.1\u03bcm PVDF ultrafiltration<\/strong> Membrane uses a PVDF coated membrane with 0.1-micron filtration precision<\/strong>, while a 0.01\u03bcm PVC ultrafiltration membrane<\/strong> uses a PVC ultrafiltration membrane with 0.01-micron filtration precision<\/strong>.<\/p>\n\n\n\n

0.1\u03bcm PVDF Ultrafiltration Membrane: PVDF Coated Membrane with 0.1-Micron Filtration Precision<\/h2>\n\n\n\n

The 0.1\u03bcm PVDF ultrafiltration<\/strong> Membrane generally uses a PVDF coated membrane<\/strong>, with a filtration precision of 0.1 micron<\/strong>.<\/p>\n\n\n\n

The 0.1-micron PVDF ultrafiltration<\/strong> Membrane is mainly used for relatively clear water and can be installed on the main incoming water pipeline of a whole house<\/strong> for whole-house water purification. It is also suitable for filtering turbid well water, rural muddy water, stream water, mountain spring water, and other natural water sources.<\/p>\n\n\n\n

The 0.1\u03bcm PVDF ultrafiltration<\/strong> Membrane can effectively intercept impurities such as sediment, rust, colloids, and insect eggs<\/strong>, helping clarify the water quality before the water enters the household pipeline.<\/p>\n\n\n\n

Main Advantage of 0.1\u03bcm PVDF Ultrafiltration Membrane<\/h3>\n\n\n\n

A major advantage of the 0.1\u03bcm PVDF ultrafiltration<\/strong> Membrane is that the filter element can be repeatedly cleaned through regular hand washing<\/strong>. Regular cleaning can remove accumulated impurities from the membrane surface and help extend the service life of the filter element.<\/p>\n\n\n\n

The main disadvantage is that some customers may consider regular hand washing inconvenient.<\/p>\n\n\n\n

0.01\u03bcm PVC Ultrafiltration Membrane: PVC Ultrafiltration Membrane with 0.01-Micron Filtration Precision<\/h2>\n\n\n\n

The 0.01\u03bcm PVC ultrafiltration membrane<\/strong> generally uses a PVC ultrafiltration membrane<\/strong>, with a filtration precision of 0.01 micron<\/strong>.<\/p>\n\n\n\n

The filtration precision of a 0.01-micron PVC ultrafiltration membrane<\/strong> is 10 times higher than that of a 0.1-micron PVDF ultrafiltration<\/strong> Membrane. Therefore, the two membrane types should not be regarded as having a filtration precision range of 0.1~0.01 micron.<\/p>\n\n\n\n

The 0.1-micron filtration precision<\/strong> generally refers to 0.1\u03bcm PVDF ultrafiltration<\/strong> Membrane, while the 0.01-micron filtration precision<\/strong> generally refers to 0.01\u03bcm PVC ultrafiltration membrane<\/strong>.<\/p>\n\n\n\n

From a more professional industry perspective, the 0.01-micron PVC membrane<\/strong> is considered an ultrafiltration membrane in the true sense, while the 0.1-micron PVDF coated membrane<\/strong> is generally called a microfiltration membrane.<\/p>\n\n\n\n

0.01-Micron PVC Ultrafiltration Membrane for Whole-House Water Purification<\/h2>\n\n\n\n

The 0.01-micron PVC ultrafiltration membrane<\/strong> can be used for whole-house water purification and installed on the main incoming water pipeline.<\/p>\n\n\n\n

For example, the ChengrongTimes intelligent ultrafiltration pre-filter<\/strong> uses an ultrafiltration membrane to further improve water cleanliness. On the basis of filtering common particulate impurities, the system can also remove bacteria and viruses<\/strong>, providing a higher level of water purification for water entering household pipelines.<\/p>\n\n\n\n

This makes the 0.01-micron PVC ultrafiltration membrane<\/strong> suitable for whole-house water purification applications where higher filtration precision is required.<\/p>\n\n\n\n

0.01-Micron PVC Ultrafiltration Membrane for Mineral-Water-Like Kitchen Water Purifiers<\/h2>\n\n\n\n

In addition to whole-house water purification, the 0.01-micron PVC ultrafiltration membrane<\/strong> can also be used in mineral-water-like kitchen water purifiers<\/strong>.<\/p>\n\n\n\n

For kitchen water purification, activated carbon can be added before the ultrafiltration membrane. The activated carbon helps improve the taste of the water, while the ultrafiltration membrane provides high-precision filtration.<\/p>\n\n\n\n

The combination of activated carbon and ultrafiltration<\/strong> can produce mineral-water-like drinking water with a cleaner taste and high-quality daily drinking water performance.<\/p>\n\n\n\n

For municipal tap water<\/strong>, this filtration process can provide clean mineral-water-like water while retaining naturally occurring minerals and trace elements in the water.<\/p>\n\n\n\n

Chengrong’s Residual-Chlorine-Removing Ultrafiltration Membrane<\/h2>\n\n\n\n

The 0.01\u03bcm PVC ultrafiltration membrane<\/strong> used in Chengrong’s mineral-water-like kitchen water purifier<\/strong> is different from the 0.01\u03bcm PVC ultrafiltration membrane<\/strong> used for whole-house water purification.<\/p>\n\n\n\n

Chengrong Factory independently developed a residual-chlorine-removing ultrafiltration membrane<\/strong>. In addition to intercepting particulate impurities, bacteria, and viruses in water, this membrane also provides a residual chlorine removal function<\/strong>.<\/p>\n\n\n\n

This additional filtration function helps improve the quality and taste of purified water and supports the production of mineral-water-like drinking water.<\/p>\n\n\n\n

Chengrong Ultrafiltration Membrane Retains Minerals and Trace Elements<\/h2>\n\n\n\n

Unlike RO reverse osmosis membranes<\/strong>, Chengrong’s independently developed residual-chlorine-removing ultrafiltration membrane can retain natural minerals and trace elements<\/strong> in water.<\/p>\n\n\n\n

Minerals such as calcium and magnesium<\/strong> are naturally present in water. Retaining these minerals allows the purified water to maintain its natural mineral composition rather than removing them through the high-rejection mechanism of RO reverse osmosis.<\/p>\n\n\n\n

The combination of ultrafiltration membrane technology, mineral retention, and residual chlorine removal<\/strong> provides a different water purification solution from RO reverse osmosis systems.<\/p>\n\n\n\n
