Demineralization stations
Ion exchange resins, reverse osmosis, continuous electrodeionization (CEDI), mixed-bed resins (ultrapure water), hardness removal, steam-generating systems. Individual design for the industrial process. With mixed-bed resins: demineralized water with conductivity below 0.1 μS/cm.
| Ion exchange resins | Reverse osmosis | |
|---|---|---|
| Advantages | Best water quality (compared with single-pass osmosis); lower water and energy consumption | No regeneration eluates; simple and quick installation; no acid or caustic soda for regeneration |
| Disadvantages | Consumption of acid and alkaline reagents; longer installation; twin cation/anion line for continuous operation | Lower water quality in a single-pass system; higher energy consumption; concentrate losses of approx. 30% |
Wastewater treatment plants
- Physico-chemical (continuous and batch operation)
- Biological (activated sludge, nitrification, denitrification, oxidation)
- Industrial wastewater from various production processes
- Platforms for liquid waste disposal and filtrate treatment
For sludge dewatering: filter presses. For wastewater concentration: evaporators.
