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. |
