Cost-efficient and future-compatible
The introduction of the TFS candle filter (Twin Flow System) in the spring of 2002, marked a significant advance in terms of precoating filtration’s equipment design and process engineering. Since then, more than 100 TFS filter systems have gone into operation worldwide. This article examines the empirical feedback obtained for the TFS filter system from both a technological and cost-efficiency viewpoint. The capital investment pays for itself within two to three years, thanks to the savings achieved in processing materials, water and energy compared to conventional precoating filters. With the TFS system, state-of-the-art precoating filtration is technologically future-compatible, in that it can be changed over at any time quite simply to alternative filtering aids like regenerative pulps or plastic granules.
