FLUIDISED BED: ALL CLEAR: A FLOATING SOLUTION

The Lewatit® fluidized bed system is a special countercurrent technology that works with upflow exhaustion and downflow regeneration. The process has been patented for Lewatit® as a further logical development of the basic principle of countercurrent technology.

The resin "floats" between the upper and lower nozzle plates of the column. Between the resin layer and the upper nozzle plate is a layer of inert resin. The interior of the unit is deliberately small, just about large enough to accommodate the changing volume of the resin between exhaustion and regeneration.

The advantages for the user are: greater efficiency in regeneration, less regenerant chemicals, maximum utilization of the tank volume and lower water consumption.
