Desalination Energie Rechner — Formel
## How to Calculate Desalination Energy
Desalination removes salt from seawater to produce fresh water, requiring significant energy.
### Formula
**Daily Energy = Volume (gal) * Energy Rate / 1,000**
### Energy Requirements (kWh per 1,000 gallons)
- **Reverse osmosis (RO)**: 10-15 kWh
- **Multi-stage flash**: 20-30 kWh
- **Multi-effect distillation**: 15-25 kWh
- **Forward osmosis**: 8-12 kWh (emerging)

Lösungsbeispiel
A small RO plant producing 100,000 gal/day at 12 kWh/1000 gal with $0.10/kWh electricity.
- Daily energy: 100,000 * 12 / 1,000 = 1,200 kWh
- Daily cost: 1,200 * $0.10 = $120
- Annual cost: 1,200 * 365 * $0.10 = $43,800
- Cost per 1,000 gal: 12 * $0.10 = $1.20
