The desalination of adulterated water for potable water is very important and in-demand because of the scarcity of the potable water. The bubble column (BC)-type humidification-dehumidification (HDH) desalination systems have shown promising results for low quantum need of fresh water. The present work consists of bubbler humidifier for increasing the humidity of atmospheric air and thermoelectric cooling (TEC) modules for the dehumidification of the humidified air. The air and water have been heated through external device for the sake of performance enhancement. The work of the proposed HDH system has been assessed experimentally as well as theoretically in order to identify the impact of system operational parameters like temperature of air and water, diameter of hole on the periphery of circling tube, height of hot water column, and the air mass flow rate on the production of fresh water.The daily distillate production achieved during the investigation was in the range of 7 to 13 L/d for different operational parameters although the best experimental productivity of the system was reported 12.96 L/d for 2 mm of hole diameter, 0.016 kg/s of air mass flow rate, 60°C of temperature of water, 27°C of temperature of air, and 7 cm of water column height in the humidifier.The gained output ratio of the system was 0.8 for 0.016 kg/s of mass flow rate of air. A theoretical model of the system is also proposed, and results of model are validated against experimental results, which have shown the great agreement.Nomenclature Notation: A, water area, m 2 ; a s , specific surface area, 1/m; C p , specific heat, J/kg K; D, diameter, m; d o , diameter of hole on spiral tube, mm; D AB , diffusion coefficient, m 2 /s; G, gravitational acceleration, m/s 2 ; h, specific enthalpy, J/kg; h fg , latent heat of evaporation, J/kg; h t , heat transfer coefficient, W/m 2 , air superficial velocity, m/s; V c , liquid circulation velocity, m/s; V b , bubble velocity, m/s; V, volume of bubble column, m 3 ; W, specific humidity, kg/kg of dry air; x, mass flow rate, kg/s; z, height of water column in humidifier, cm Greek letters: ε, void fraction; Ρ, density, kg/m 3 ; σ, surface tension of water, N/m; α, Seebeck coefficient, V/K Subscript: 1, air at humidifier inlet; 2, air at humidifier outlet (dehumidifier inlet); 3, air at dehumidifier outletHow to cite this article: Patel V, Patel R, Patel J.
