Membrane filtration

Filtration spectrum

Ultrafiltration is just a small part of water treatment. And ultrafiltration is just one type of membrane filtration. Depending on your goal you should decide what type of filtration  you will implement. Ultrafiltration modules from PB International are the perfect solution for water disinfection and clarification, while the membranes will remove everything bigger then 0,02 micron….

What is microfiltration?

Like ultrafiltration, microfiltration is a physical barrier where the size of the pores determines which solids are allowed to pass. The pores of a microfiltration membrane are between 10 and 0.1 µm; with ultrafiltration, pore sizes of 0.001 to 0.1 µm are possible. Microfiltration is available in various forms; Filter cartridges Filter bags Hollow fibre…

What is ultrafiltration?

Ultrafiltration is a pressure-driven membrane technology to remove (colloidal) particles, sediment, turbidity, bacteria and viruses. Depending on the molecular weight, UF will also remove a wide range of the humin and humic acid range and suspended iron particles. Ultrafiltration is commonly used in the treatment of surface water, rain water, well water, borehole water, seawater…

What is nanofiltration?

The filtration spectrum below shows that ultrafiltration is succeeded by Nanofiltration. NF is defined by a pore size of approximately 1nm (0.001μm) and a cut-off of 150 to 500 Dalton. In comparison, the pore size of PB International membranes is approximately 10 and 20 nanometres (0.01-0.02μm). Nanofiltration can occur in the following forms; Hollow fibre…
