Akualys PVDF pressurized UF membranes

Akualys ultrafiltration units consist of hollow fiber membranes made of PVDF, configured with an OUT-IN feed direction. They are suitable for turbidity removal from water sources intended for drinking water production (rivers, lakes, dams, artificial reservoirs), for pre-treatment and treatment of primary water for industrial use, and for tertiary treatment of wastewater.

The membranes used in these ultrafiltration modules offer a filtration precision of approximately 0.03 microns. As a result, in addition to turbidity removal, they are capable of significantly reducing concentrations of bacteria such as Giardia and Cryptosporidium, and lowering SDI values to meet the strict requirements for reverse osmosis and nanofiltration pre-treatment.

The basic building block of an Akualys membrane system is the filtration module, which contains thousands of PVDF hollow fiber membranes designed to perform filtration from the outside in (OUT-IN). Suspended solids and colloidal substances are retained on the outer surface of the hollow fibers and trapped in the free space within the filtration module, while the permeate flows through the lumen of the membrane, which is exclusively dedicated to transporting solids-free water.

The upper part of each Akualys module head is equipped with a special transparent inspection window, allowing users to continuously monitor permeate quality and quickly detect any fiber breakages. This makes it possible to isolate the damaged module immediately.
