“…The average volume of water produced from conventional solar still is 0.8 liters per hour of sun per meter square. [10]. In 2014, globally the cost of freshwater from solar distiller ranged between 0.019$/m 3 and 0.02$/m 3 depending on the shape of the still [11].…”

Distillation has been a very important separation technique used over many centuries. This technique is diverse and applicable in different fields and for different substances. Distillation is important in the desalination section. Various principles are used in desalting seawater and brackish water to fulfill the demands of freshwater. This work explains the modes and principles of distillation in desalination, their types, present improvement, challenges, and limitations as well as possible future improvements. The first and primary mode of distillation is the passive type. As times went by and the demand for freshwater kept increasing, other modes were introduced and these modes fall under the active distillation type. However, each mode has its own advantages, disadvantages, and limitations over each other. The principles and modes of distillation are as significant as understanding the energy sources needed for distillation. Hence, they are the basic knowledge needed for future innovation in the desalination industries.

“…When the wind speed is increased from 2.7 to 5 m s −1 , productivity is shown to improve by 35%; however, when the temperature is raised from 28 to 32 °C, productivity increases by 53%. Singh et al (2021) stated that there are contrasting findings on the effects of wind on the productivity of SS. With an increase in solar intensity, SS productivity is also increasing.…”

Conventional raw water treatment methods are expensive and require a sufficient energy supply for their operations. In remote and rural areas, these conventional methods are feasible due to poor economy and interrupted power supply. This study provides a sustainable approach to treating raw water using solar energy and phase change material (PCM). Passive solar stills (SS) are sufficient to treat water in the presence of solar radiation and we can increase the yield and quality of distillate water by using calcium chloride hexahydrate as phase change material. Moreover, PCM-based solar still is also advanced by adding activated charcoal (AC) for the removal of fluoride from the raw water. The efficiency of solar still was assessed for the eight parameters: yield (Y), fluoride (F), total dissolved solids (TDS), electrical conductivity (EC), pH, total alkalinity (TA), total hardness (TH), chloride (Cl). Through the number of water quality assessments, it was found that SS with PCM can reduce (%) the TDS (85-100%), EC (90-100%), pH (0-15%), TH (90-95%), TA (75-90%), Cl (80-100%) and can increase the yield by 10-15%. SS with PCM and AC was also shown a good removal of F from raw water. In addition to that a statistical analysis was also carried out to understand the effect of different climatic factors on the performance of solar still.

“…Researchers across world progress in improving the productivity of passive and active solar stills by adopting different techniques that in uences the rate of evaporation and rate of condensation of solar stills (Manokar et al, 2014). Singh et al, (2021) reviewed the design, operational and environmental characteristics on solar still performance. Performance enhancement techniques associated with new designs and modi cations in a passive solar still were reviewed by Mohsenzadeh et al, (2021).…”

Water plays a vital role in defending the contagious diseases globally, leading to continual increase in demand of water. The increase in demand in turn reduces the fresh water availability. To meet this water demand desalination technologies can be used for fresh water production from seawater. Passive solar distillation techniques are the simplest and favourable, as they use sustainable renewable solar energy as a source. Rate of evaporation and rate of condensation are the major in uencing factors which have a direct impact on distillate yield. Single basin single slope conventional solar still (CSS) and single basin single slope solar still with inbuilt condenser and agitator (SSICA) were designed and fabricated for the current study. Both the stills were tested under same ambient condition to compare the performance.Through experimental results, it was found that SSICA had 98.69% more productivity than CSS. The agitating effect caused by agitator in SSICA led to increase in rate of evaporation. The increase in condensing area for same evaporation area of SSICA improved the condensation rate. These two synergized effects resulted in overall performance improvement of SSICA over CSS. Energy analysis revealed that SSICA is 24.42% more e cient than CSS. Exergy e ciency of SSICA and CSS were calculated as 4.82% and 2.04% respectively.
