Sept. 17, 2013 -- According to a recent forecast in Sedimentation/Centrifugation World Markets, published by the McIlvaine Company, municipal wastewater plant operators across the globe are predicted to spend $1.2 billion in 2014 for equipment to separate particles from sewage inflows.
The results of the analysis for 2014 are:
East Asia: $527M
Eastern Europe: $69M
Middle East: $57M
South & Central America: $38M
West Asia: $74M
Western Europe: $102
Nearly half of the purchases will be made in East Asia. In just a few decades, China has invested as much in treatment hardware as the U.S. has in the last fifty years. Consequently, the U.S. has some 110 year old plants where 90 percent of the Chinese plans are less than twenty years old.
Centrifuges are competing with belt filter presses for sewage sludge dewatering applications. Clarifiers and thickeners are widely used for separation processes. There is relatively little use of hydrocyclones and automatic backwash filters which are common sedimentation devices used in other industries. Dissolved air flotation is used in some plants but not all.
