Main applications of Diemme Filtration products in the food sector

Diemme® Filtration has developed a great deal of experience in many applications including: processing and purification; for example:

  • filtration/purification of vegetable oils, animal oils;
  • purification of beer, wine, beverages;
  • dewatering of sludge produced from physico-chemical and/or biological treatment of industrial waste water.

Often these applications require very detailed customization, linked to the choice of materials suitable for contact with the products (e.g. FDA compliant), including but not limited to, surface treatment of metal parts and adaptation to specific sector standards (DIN, etc.).

Sometimes the use in purification also requires treatment using kieselguhr/diatomaceous earth or other filter aids.
