A SHORT CHARACTERISATION OF OUR PRODUCT LINES

UVK line of products for conventional operation
Regeneration in co-current flow. The water flows from top to bottom through the resin in the operating phase forming a fixed bed. The order of functions:
1. operation, 2. backrinsing, 3. suctioning (displacing = by shutting off the suction line) 4. washing

UVG line of products for counterflow fluidised bed operation
The water flows from bottom to top through the resin ( = the operating phase) and it is suspended. Regeneration: from bottom to top. Resin turbulences and rearrangement have to be avoided. Inert resin is necessary. The order of functions: operation, suctioning, displacing and washing.
UVR line of products for backflow regeneration
Fixed bed operation. The water flows from top to bottom (fixed bed) through the resin ( = the operating phase). Regeneration: from bottom to top. Resin turbulences and rearrangement have to be avoided. Inert resin is necessary. The order of functions: operation, suctioning, displacing and washing.
UVM line of products for mixed bed operation
The water flows from top to bottom through the resin ( = the operating phase) forming a fixed bed. Regeneration: with alkaline solution from the top, with acid from the bottom, both to the centre distribution system. Aeration and dearation is necessary for the resin mixture. The order of functions: operation, backrinsing/separating, suctioning and washing.
