SCANNING ELECTRON PHOTOMICROGRAPH of an expanded perlite particle magnified approximately 9,500 times actual size to show its glasslike cellular structure. When shattered, this structure produces one of the world's great filteraids because every fragment has a// curved surfaces, forming an almost incompressible filter cake. From the DICALITE perlite collection. By courtesy of the Laboratory of Electronmicroscopy, Ghent University, Belgium.

Switching to Dicalite perlite filteraids may give you every third, fourth or fifth bag free. This is because Dicalite perlite forms filter cakes at consider ably lower densities than diatomite. The range is 20% to 50% lower, espe cially on vacuum precoat filtration. The way to tell exactly how perlite can serve you is to ask for a free inplant test. Only Dicalite engineers are equipped to test your production liquors using the Dicalite Pressure Test F i l t e r or the Dicalite R o t a r y Vacuum Precoat Test Leaf. Only Dicalite is your single source
for a full range of filtration materials, including perlite, diatomite, SolkaFloc® cellulose, Diabestos®, DiaFloc®, a c i d - w a s h e d a n d n o n - a c i d washed asbestos. New deposits of both diatomite and perlite assure users of Dicalite filteraids an unlimited supply—well into the 21st Century. Another Dicalite product—DicaSorb™ high-bulk sorbent—has been developed as an aid to combat pollu tion. An 18-lb. bag of Dica-Sorb can absorb 9 to 15 gallons of oil, depend ing on viscosity.
