The performance of a membrane filtration system is related to certain operating conditions; with time such conditions may change for external reasons. The causes of this change, if we consider the characteristics of the food fluid stable over time, can be related to membrane fouling, due to the accumulation of different materials on the membrane surface.

Cross-flow filtration modules, unlike traditional filters, can be regenerated by means of specific cleaning cycles with specially designed products to:


  • Reset initial capacity.
  • Maintain high performance over time and increase the useful life of the membrane.
  • Remove pollutants of various nature that could alter product characteristics, such as microbiological pollution and biofilm development.

Taking advantage of its experience in the use of membranes in cross-flow filtration plants, SEPRA has developed a line of chemicals aimed at solving the specific problems that they encounter such as fouling, scaling, bacterial contamination, sanitation and storage.

SEPRA is able to develop the best cleaning procedures dedicated to membrane filtration systems, in order to ensure optimal productivity.

This analysis can be done on site, but also collecting a using membrane elements and analyzing it in our laboratories. The membrane authopsy service is carried on using our test cell to test flat membrane sheets collected from industrial elements and eventually also using electronic microscopy and mass analysis.
