Frequently Asked Questions

According to CeraMem, the manufacturer of Kleansep and Micro-Kleansep membranes, the membranes can be cleaned before use with soft water containing 200 ppm NaOCl, at pH 10 and 50°C, for 20 minutes.

The ceramic membrane disk filters are considerably thicker than conventional membrane disk filters and will not fit in conventional disk filter holders.  The ceramic membrane disk filters must be used with the specially designed holders offered here.

The ceramic membrane filters are only available with 47mm and 90mm diameters. You may want to consider other inorganic membranes, such as alumina oxide or silver, for applications requiring different diameters.

Ceramic membrane filters are manufactured from a robust inorganic matrix of zirconium oxide and titanium dioxide, providing exceptional mechanical strength, chemical resistance, and thermal stability. These inert ceramic filtration membranes can operate at temperatures up to 350 °C, far exceeding the limits of conventional polymer membrane filters.

Thanks to their superior resistance to aggressive chemicals, solvents, and extreme pH conditions, ceramic membranes are ideally suited for demanding filtration applications. Their durability allows for repeated regeneration, backflushing, and high-temperature or chemical cleaning without loss of performance.

These advantages make ceramic membrane filters well suited for industrial filtration, pharmaceutical processing, biotechnology, food and beverage applications, and other processes requiring long service life, consistent performance, and high-temperature operation.
