Thin-Cake Filtration Technologies for Removing Activated Carbon, Catalysts and Other Trace Solids From Active Pharmaceutical Ingredient (API) Slurries
, the industry's need for new technologies has expanded. One area of importance is now the efficient removal of activated carbon, metal catalysts and trace insolubles, such as diatomaceous earth, from API slurries. Currently, most API slurries are clarified with the use of manual plate filters, filter

Some "Trash-Talk" Worth Listening to Activated Carbons in a Nutshell
) Carbon uses run the gamut: from fish tank filters and tap water purifiers to wastewater treatment and air pollution monitoring and control. In the United States, such applications consume over 300 million pounds of activated carbons annually about half the 600 million pounds used worldwide. "One

Using Organoclays to Remove Oil From Water
proposition for cutting operations costs. Synthetic oils are more difficult to remove than mineral oils. They require a higher amount of chemicals to achieve clarity, and below about 100 ppm are not visible to the eye. Organoclays also are used as final polishers, often followed by activated carbon
