Dorr-Oliver Eimco Flotation Technology
2017-10-2 Cell Technology with the Greatest Installed Capacity of any Flotation Manufacturer Dorr-Oliver Eimco pioneered the way for large cell technology. From its first Wemco 257m3 cell installed in 2003, to now even bigger 300m3 cells being installed in Chile. These 26 x 300m3 Wemco cells will be the first major installation of 300’s for

2018-3-21 Induced Gas Flotation (IGF) and Induced Static Flotation (ISF) units provide a more enhanced approach to oil removal through the addition of gas bubbles to aid in the flotation of oil to the surface. Gas, which is typically induced by sparging tubes or eductors, floats the oil to the surface, which can then be skimmed off. In addition
