TLCHF-FP Aquafilter capillary membrane

Capillary membrane for under-sink systems

The TLCHF-FP model by Aquafilter has been designed for use in under-sink systems. It is a solution for users who want to improve the quality of tap water by removing mechanical impurities and very fine particles, while not wanting to strip the water of its naturally occurring minerals.

In practice, the membrane helps reduce the presence of contaminants such as sand, silt, rust, and other suspended matter present in tap water. Its filtration capability down to 0.02 µm also allows it to retain some bacteria and viruses.

How capillary filtration works

The capillary membrane is made of fibers, or capillaries. In the walls of each capillary there are channels whose diameter decreases from the outside toward the center of the fiber. This structure is responsible for a multi-stage, highly effective contaminant separation process.

Larger particles are retained on the outer surface of the capillary, which corresponds to surface filtration. Smaller particles move deeper into the channel structure and are retained when they encounter even finer pores, in a process known as depth filtration.

As a result, the membrane combines high purification accuracy with maintaining the full incoming water flow. Capillary filtration is an alternative to osmotic filtration and, for many household applications, is a very convenient solution wherever the absence of reject water and the preservation of minerals present in the water are important.

Key user benefits

• Made of thin capillaries with a diameter of 0.02 micron.
• Does not remove minerals from the water.
• Filtration without reject water.
• Removes some bacteria and viruses.
• Removes mechanical impurities, including rust, sand, silt, and suspended solids.

Filtration efficiency and operating characteristics

The capillary filtration process makes it possible to eliminate 99.8% of harmful substances and microorganisms from water without removing the minerals essential for the human body. This is an important difference compared with solutions focused on very deep demineralization of water.

The TLCHF-FP membrane filters 100% of the incoming water, which means filtration without reject water. The entire stream of supplied water passes through the purification process, without the water losses typical of many systems using solutions such as an osmotic membrane or selected reverse osmosis systems.

System compatibility

The TLCHF-FP capillary membrane is compatible with the following solutions:

• under-sink systems from the FP3-HJ-K and FP2-HJ-K series
• AFDL-2-HQ water dispenser (Aquafilter® Vodaro)
• Shopure® ECO capillary system
• EXCITO under-sink system

Application in domestic water treatment

TLCHF-FP works well as a component of a system that improves the quality of utility water in the kitchen, especially where effective retention of fine impurities is expected while maintaining the natural mineral composition. It is a solution for people looking for a compromise between filtration accuracy and economical operation.

Unlike solutions referred to as an osmotic filter or osmotic membrane, capillary filtration does not generate reject water. For this reason, it is chosen wherever savings and simpler operation of the filtration system are important.
