Case: Documented results from wastewater plant
Reuse of wastewater saves water and money
A large Danish wastewater treatment plant has safely reused treated wastewater for more than 10 years, saving an average of 60,000 m³ of drinking water and DKK 548,000 every year. The water is disinfected with our solution.
Documented safety
Neuthox is classified as non-hazardous according to EU regulation, which means:
- No personal protective equipment is required
- It is not flammable
- No hazard pictograms are needed
How much water can DCW Large treat?
The table shows the approximate amount of water that each DCW Large T25 model can treat per day in typical applications. The first column shows the unit's Neuthox production capacity in litres per hour (l/h), while treated water capacity is shown in cubic metres per day (m³/day). Actual capacity depends on the specific application and the required dosing level.
| Neuthox production 500 parts per million (ppm) |
Wastewater reuse 10–15 ppm |
Process water 0.5–2 ppm |
Livestock water 5 ppm |
|---|---|---|---|
| 125 l/h | 167–250 m³/day | 625–2,500 m³/day | 500 m³/day |
| 200 l/h | 267–400 m³/day | 1,000–4,000 m³/day | 800 m³/day |
| 250 l/h | 333–500 m³/day | 1,250–5,000 m³/day | 1,000 m³/day |
| 300 l/h | 400–600 m³/day | 1,500–6,000 m³/day | 1,200 m³/day |
| 400 l/h | 533–800 m³/day | 2,000–8,000 m³/day | 1,600 m³/day |
The treated water capacity is based on 20 hours of Neuthox production per day. Neuthox is stored in a tank to ensure continuous dosing and protection 24/7.
Cooling towers
The capacity requirement for cooling towers is calculated differently because water continuously evaporates and part of the water is discharged from the system. The table below provides an indication of the recommended Neuthox production capacity for different cooling tower sizes.
Contact us to discuss your needs| Neuthox production | Cooling tower size |
|---|---|
| 125 l/h (LC) | 3,000 kW |
| 4,000 kW | |
| 250 l/h (LC) | 5,000 kW |
| 6,000 kW |
Larger cooling towers may require multiple units.
