Reducing maintenance costs and increasing process reliability: with these objectives in mind, ESIM Chemi-cals (www.esim-chemicals.com) conducted a detailed analysis of the Funda filters they have been using for many years in their large scale fumaric acid produc-tion. In addition to changes to the technical settings of the apparatus, the screening of the disc filters was redesigned in terms of weave, material and finishing. For this, ESIM Chemicals turned to GKD - Gebr. Kufferath AG (http://gkd-web.eu/en), an international filtration specialist and manufacturer of high perfor-mance filter meshes for a wide range of application fields including the chemicals industry.
