This firm’s decanters and disc-stack centrifuges assume a key role in the mechanical separation operations in the chemical and pharmaceutical industries, including clarification of liquids, classification of solids, and dewatering liquid-solid suspensions and liquid-liquid separations. The firm’s decanters and disc-stack…
The MobileMinor Basic spray dryer (photo) is said to meet all the basic requirements of laboratories, especially those in small companies and universities, and other laboratories that don’t need many of the options available for the advanced MobileMinor models. The…
Radio Frequency The Macrowave radio frequency (RF) drying system heats filter cake material uniformly to remove water without overheating. The drying system is a suitable replacement for tumble, spray, tray, spin flash and belt/tunnel dryers, and can reduce labor and…
A high-flowing, low-pressure-drop carbon filter, the NanoCeram-PAC water-filter cartridge contains an electropositive (approximately 50 mV) filter media composed of nano-alumina on a microglass fiber matrix, with synthetic polymer fibers for increased pore size, flexibility and strength. Recently certified to NSF/ANSI…
