The market for sedimentation and centrifugation equipment will exceed $6.2 billion in 2011, up from $6.1 billion in 2010. This is the new forecast appearing in the continuously updated online Sedimentation & Centrifugation World Markets published by the McIlvaine Company www.mcilvainecompany.com.
Decanter, disc and other centrifuges will account for $2. 6 billion in sales revenue. This will be slightly less than the clarifiers and thickeners at $2.7 billion. Dissolved air floatation and hydrocyclones revenue will be just less than $1 billion.
Clarifiers and thickeners are used in mining, wastewater treatment and other processes to separate particles from liquids using gravity. Decanter centrifuges are widely used to dewater municipal sewage sludge. They are also used in many chemical, food and refinery processes.
Disc centrifuges are used to separate liquids-from-liquids as well as solids-from-liquids and are used in dairy, food and drink, fuel oil clarification and many other processes. Other centrifuges includes basket designs used in chemical processes, coal separation and food processes.
Hydrocyclones remove coarser particles and are frequently used in the stone and gravel industries and as preliminary separators in many processes. Dissolved air flotation involves capturing particles on the surfaces of bubbles. It is used in water and wastewater treatment and in the food industry. The high growth areas include municipal wastewater treatment in Asia, the petrochemical industry in the Middle East, oil sands in Canada and mining in Africa.
Major international suppliers of sedimentation and centrifugation equipment include Alfa Laval, Andritiz, FLS, GEA Westfalia, GLV, Pieralisi, Siemens and more than 5,000 other companies. A number of Chinese suppliers have grown rapidly in the last few years and have captured significant market share within China and nearby countries.
