High Rate Thickeners Perhaps the most significant design optimisation effort in thickening in the last twenty years has been in developing ways to more effectively use the horizontal cross sectional area of the thickener. The introduction of polymeric flocculants gave an impetus to development of High Rate Thickeners.
The advantage of associative thickeners is their ability to decrease viscosity at high rates (good film build, low roller spatter) while maintaining a still low viscosity at low rates, which improves flow, leveling and gloss. The disadvantage is the instability of these systems (phase separation) and the

The high time for thickeners was in the 60's when the metallurgical industries were booming and sizes of up to 150 m diameter were constructed. Such jumbo thickeners, when centrally driven, require for most demanding applications extra heavy duty drive heads some of which reach a continuous operating torque of 3.300.000 Nm.
The rate at which a floc particle drops out of the water has to be faster than the rate at which the water flows from the tank’s inlet or slow mix end to its outlet or filtration end. The difference in specific gravity between the water and the particles causes the particles to settle to the bottom of the basin.
