Weighing Alternative API Filtration Technologies
Photo by Ivan Bandura on Unsplash Being a process engineer is all about making choices. When it comes API filtration technologies, many different types of equipment can be used for removing catalyst residues. While conventional filtration equipment is operated manually, I recently worked with PharmTech on an article outlining how both candle filters and pressure plate filters are operated as automated systems. This article reviews what we discussed. Pharmaceutical manufacturers are…
Troubleshooting Filter Aids and Filtration Systems
Filter aid pretreatment can improve filtration properties and efficient removal of fine solids. Whether the filter aids are used in Plate-and-frame filter presses, horizontal and vertical pressure leaf filters, candle or tubular filters, Nutsche filters, or rotary vacuum drum filters, these practical tips can help this part of the process run smoothly. We typically see diatomite, perlite and cellulose filter aids today. They meet the requirements of a filter aid in that they: Consist of rigid,…
