Water Clarification by Flotation -1

The apparatus used is generally termed a flotation cell and when surface-active agents, such as 'collectors' and frothing agents, are employed, the process is known as froth flotation. Alternatively, a gas and liquid stream may be homogenized or air may be diffused through suitable porous media. Dispersed-air flotation systems produce air

Chylomicrons and large VLDLs (Svedberg flotation unit [S f] 60 to 400) are probably not capable of entering the arterial wall. On the other hand, small VLDLs (S f 20 to 60) and IDLs (S f 12 to 20) can enter the arterial intima. Therefore, certain triglyceride-rich lipoproteins are atherogenic, whereas others are not.
