This is an edited version of an article I wrote for The Chemical Engineer. I hope you enjoy this take on automated clarification technologies.
Throughout my career in the solid-liquid separation market space, I have seen some interesting solid-liquid separation solutions. At one melamine resin facility, the slurry was in a formaldehyde…
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…
My Thoughts on Filtration Separation Trends and Practices

I recently had the opportunity to share my ideas on filtration separation trends and practices with World of Chemicals magazine. My favorite part may have been the headline, "Aging with perfection in filtration technology." I like to think they were talking about me — ha ha!
In the meantime, I thought I'd excerpt some of the thoughts I shared in that…
Inventive Filtration Technologies for Palladium Recovery

Many times we encounter an “if it ain’t broke don’t fix it,” mentality. Process engineers in particular run up against this constantly. Yet, when it comes to palladium recovery, we’ve seen some strong results from taking an inventive approach to the filtration technologies uses. Currently, in recovering palladium catalysts the slurries are clarified with…
Benefits of a Continuum Approach to Optimizing Final Drying

As we announced in March, BHS has acquired AVA-GmbH. The AVA technologies provide for turbulent mixing, reacting and drying of wet cakes as well as powders and process slurries. The vertical and horizontal technologies are vacuum or atmospheric, batch and continuous, for final drying to “bone-dry” powders. They are an essential part of our “Continuum…
