Activated carbon

Clear filtrate and a pure final product

Activated carbon is used in many different process steps in the chemical and pharmaceutical industries to separate and clean suspensions (usually solvent-based) and to influence reaction processes. In these processes, the purity of the final product or the filtrate has the highest priority. As a result, highly effective filter systems are required, especially in the pharmaceutical industry. With our candle filters (type CF) and pressure plate filters (type PF), these requirements can be met. Filtrate clarity, easy cake discharge and safe handling are ensured. Our Autopress (type AP) is a well-proven solution for activated carbon in the pharmaceutical industry.

Thin-cake filtration technologies for removing activated carbon, catalysts and other trace solids from Active Pharmaceutical Ingredient (API) slurries

This article discusses the use of thin-cake vertical candle filters and horizontal pressure plate filters as alternatives to manual and conventional filter equipment. These new technologies are described as well as the selection process. The article includes test data and case histories and concludes with a discussion of clean-in-place operations and current Good Manufacturing Practices (cGMP) guidelines. ANSI/ISA S88 (and IEC 61512-1 in the international arena) batch process control system standards are also examined for validation. Finally, factory and site acceptance testing is described.
