Table 8 Comparison of performance metrics between the proposed system and other decentralized desalination technologies.
Author(s) | Studied system | SEC (kWh/L) | Water Production | Recovery ratio (%) | GOR | Remarks |
|---|---|---|---|---|---|---|
Present work | A novel small scale desalination system with loop-configured MSF and reservoir tanks | 0.63 | 4.7 (L/h) | 96 | 1 | Both thermal and electrical energy were included in SEC. |
1-Humidification–Dehumidification Desalination (HDH) | ||||||
Dehghani et al.63 | Open-air, open-water HDH system | - | 4.9 (L/h) | 88 | 0.65 | - A gas burner powered the cycle. - The recirculation of brine was investigated. |
Rajaseenivasan & Srithar64 | Open-air, open-water HDH system | - | 6.1 (L/h) | - | 1 | -Biomass fuel was used to power the cycle. |
2- Thermoelectric Desalination (TE) | ||||||
Al-Madhhachi & Min65 | thermoelectric (TE) desalinator | 1.14 | 0.684(L/m2/h) | 9.5 | 0.55 | -This system relies only on electricity. -Fresh water production is based on condenser area. |
3-Membrane Distillation (MD) | ||||||
Zuo et al66. | Vacuum membrane distillation (VMD) integrated with a crystallizer for zero-brine discharge | - | 3.7 (L/m2/h) | 95 | 1-1.59 | -The increase in GOR is due to the recovery of heat lost from the condenser. -Brine recirculation is employed to enhance the recovery ratio. |
Mohamed et al67. | Vacuum multi-effect membrane distillation (V-MEMD) | 0.3–0.7 | 2.58–7.71 (L/m2/h) | 50–85 | 1-2.2 | - |
