Low as 6. Key aspects of the design and operation of the filters that make rotary drums a viable choice for dewatering are presented. INTRODUCTION This paper will introduce the reader to the idea of using rotary drum vacuum filters RDVFs to dewater wallboard grade gypsum produced by FGD facilities. In the past typical practice was to

At low pH. At a pH above 8 significant carbonation occurs due to free calcium hydroxide in the absorber. This results in carbonate deposition on the internals including the mist eliminators. As the sulfite sulfate and carbonate compounds are formed in a supersaturated solution precipitates are formed adding to the suspended solids level and scal

Gross separation efficiencies near 80 are achievable for silica and temperatures above 300176C while in the same temperature range gross separation efficiencies for denser ircon particles are greater than 99 29. The main handicap of hydrocyclone operation is the tendency of some salts to adhere to the cyclone walls. Cross micro

Hydrocyclones operate under pressure. Fluid is directed tangentially into the hydrocyclone which causes it to spin. The spinning motion generates strong centrifugal forces which induces the solid and liquid or the two immiscible liquids to separate. The centrifugal force generated in a hydrocyclone varies over its length and may reach a

THE SIZING AND SELECTION OF HYDROCYCLONES By Richard A. Arterburn For many years hydrocyclones commonly referred to as cyclones have been extensively utilied in the classification of particles in comminution circuits. The practical range of classification for cyclones is 40 microns to 400 microns with some remote applications as fine as 5
