The cetotec filtration plants are equipped with high performance modules with capillary membranes with a nominal pore size of 0,2 µm.
Cross flow filtration involves micro-porous hollow fibre membranes. The raw vinegar is conducted at high speed diagonally to the membrane surface thus preventing the spontaneous formation of a coating.
For wine vinegar with a higher turbidity and particle size, it is recommended to use capillary membranes with a higher diameter (3mm). For spirit vinegar 1,5mm is recommended.
Yes, Cetotec offers both a retro-fit of existing modules as well as entire modules. Retro-fit means a re-fill, in this case only the inside of the modules will be re-inserted while keeping the stainless steel housing.
