Chemical and pharmaceutical industry

In the chemical and pharmaceutical industry, there are dusts which, due to their high value, are recycled into the production process. On recycling, it must be simultaneously ensured that the products are free of foreign substances and that the strict legal requirements in terms of product purity are maintained. All this demands filter media tailored perfectly to the individual requirements of the dust collector to meet the highest standards in filtration efficiency and product purity.

Typical operating conditions

Temperature Cont. (°C) 20°C-250°C
Peak (°C) Orientation to the maximum peak temperature of the fibre polymers used
Dust: Cosmetics, fertiliser, detergents, pharmaceuticals, pigments
Dust Properties: Abrasive, chemically aggressive, explosive, fine, coarse, sticky
Dust Source: Dryer, mills, mixers
Harmful Gases: H2O, NOx, volatile chemical substances
Cleaning Process: Pulse jet
Fuels: Natural gas, oil

SPECIFIC REQUIREMENTS FOR FILTER MEDIA IN THE CHEMICAL AND PHARMACEUTICAL INDUSTRY:

  • Discharge of electrostatic charges 
  • High abrasion resistance 
  • High separation efficiency 
  • Good chemical resistance 

Food industry

Filtration processes in the food industry are characterised by strict hygiene rules and strict requirements regarding static electricity. In order to ensure the highest possible purity of the product during the production and processing of food, hygiene and food-grade quality of all the components involved in the dedusting process, play a decisive role. needlona®-filter media used in the food industry are food safe, work under very wet conditions and ensure safe conductivity and discharge of electrostatic charges.

Cement, Gypsum and lime industry

Product quality and compliance with dust emission limits is a core requirement for dedusting in the cement, gypsum and lime industry. The choice of filter media is of paramount importance in cement kilns where there are high NOx levels due to high combustion temperatures. The needlona®-filter media range offers for each process in the cement, gypsum and lime industry technically sophisticated solutions.
