A method of reducing solids accumulation on a disc stack having at least one separator disc used in a centrifuge, comprising:
- providing at least one surface of the at least one separator disc, said surface having a number of crevices therein;
- and
- coating at least a portion of the at least one surface with a coating comprising at least one fluoropolymer to fill the crevices in that portion so that the solids are prevented from settling therein.
A disc stack for a centrifuge, comprising:
- at least one separator disc, wherein the at least one separator disc is at least partially provided with a surface coating that is capable of filling any crevices that may be present on the at least one separator disc to reduce solids fouling of the disc.
A centrifuge, comprising:
- a centrifugal drum for separating a product into phases;
- a separator disc stack in the centrifugal drum, the disc stack including at least one separator disc;
- and
- the at least one separator disc is at least partially provided with a surface coating that is capable of filling any crevices that may be present on the at least one separator disc to reduce solids fouling of the disc.
