OPADEN™ Technical Details
The OPADEN™ standard product range can treat from 10 up to 130 m3/h per unit.
Flexible and modular, they may be configured for higher flow-rates and water qualities.
| Model | Exchanger Diameter (mm) | Shell height (mm) | Area (m2) | Treated water per unit (m3/h) | NO3 in Raw water (mg/l) | NO3 in Treated water (mg/l) | By pass flowrate (m3/h) | Resin Capacity (eq/l) | Resin volume (liters) |

The OPADEN™ standard unit includes one or several skid-mounted ion exchangers fitted with their respective pipe work, valving, feed pump and accessories, electrical control cabinet and brine preparation tank.
A proportion of untreated water by-passes the unit as drinking water is obtained by blending. Supplementary pumping makes for the pressure drop through the nitrate removal line. The exchange capacity of the resins is restored by reverse flow of saturated brine. Operation is fully-automated, either "duplex", i. e. one duty / one standby, or "triplex", two duty / one standby. Two versions are proposed according to feed and output pressure requirements: a reinforced resin version (6 bars) and a steel version (10 bars).
- Stainless steel panoply
- Electrical or pneumatic valves
- Specific adapted ion-exchange resin for eliminating nitrates
- Brine silo
- Dissolution panoply
- Prefabricated modular building to be placed on a concrete slab
- Component stabilization system
- Rebalancing system
- Operating pressure from 0 to 16 bars
- Several options available: the unit may be housed in a heated container to make it frost-proof. Continuous nitrate monitoring and remote process control are other common options.
