- •
Energy consumption with using liquid fertilizer is dominated by recirculation.
- •
A higher initial draw concentration results in lower energy consumption.
- •
A recirculation flow rate of 25 mL min−1 requires as low as 0.09 kW h m−3.
- •
The primary effluent leads to higher energy demand due to reduced water flux.
- •
Reporting energy consumption data is critical to evaluating forward osmosis.
