“…In achieving the main objective of the study which to improve and build up the existing solar basin design which yield the optimum volume of purified water that achieve the quality of drinking water, the best performance of solar still has been compared with the previous research done by A.B.A. Hakim and M. E. Azni (2018) [13]. Throughout the comparison, they could yield maximum of 1305 ml of desalinated water for solar still with the size of 100 cm × 50 cm.…”

Solar desalination is a process of removing salt content in brackish or saline water and converting it into fresh water by the aid of solar energy. The portable solar basin was utilized to undergo this process and the collected desalinated water was to be compared with the Drinking Water Quality Standard in order to identify the safety and cleanliness of the water produced. The main purpose of this study is to improve the solar basin designs which yield the optimum volume of purified water that achieve the quality of drinking water and low cost. The solar basin was designed with the angle tilt of 15° which it able to achieve maximum sun ray exposure. The solar basin that was used is the conventional type single slope with different component inside the solar basin (without stages and rocks; with stages and without rocks; and with both stages and rocks. The source of water be used in this process is seawater (Pengkalan Balak Beach), ground water (Cherana Puteh Hot Spring) and river (small stream of Sungai Siput). The basin solar design with steps and rocks able to produce maximum desalinated water up to 1120 ml per day with average temperature of 59.7 °C, almost 100% reduction of COD, TDS, conductivity, element traces of Ca, Mg, Na and K with BOD level of 1.55 mg/l which mostly comply with the drinking water standard. KEYWORDSBasin solar energy, desalination, solar still.This project required to design and constructing the device system for the process of desalination (solar still) which at the end of the project, the yield and quality of water for three different solar still being compared.

“…Installation of a Reverse Osmosis water desalination plant is Sarawak (News Report) reflects the necessity of seawater desalination for the population in the bay areas. Recently there has been a research shift toward freshwater production by harnessing Malaysia's solar energy potentials (Abujazar et al, 2018;Hakim et al, 2018;Rafiei et al, 2019) pertaining to the need for drinking water produced sustainably; especially for the underprivileged population in the bay areas.…”

Solar desalination is a renewable energy-driven method that produces freshwater from saline/brackish water. Conventional solar desalination units are equipped with an inclined transparent condensing plate placed over a feedwater basin containing saline water. The process is limited to a small quantity of production because of scattered solar irradiation and the unavailability of solar heat due to intermittent cloudy weather. In this study, a Fresnel lens has been used to concentrate solar energy onto a spot to increase the local temperature of feedwater and the evaporation rate. Flat Fresnel lenses on a double sloped passive solar still were used, where the focal points were adjusted to fall directly on the feedwater. The experiments were conducted for two different geometries and alongside the comparison between the conventional and the modified solar still; the number of Fresnel lenses was also varied. Saline solution with a concentration of 20,000 ppm was used as the feedwater. The research is aimed to be implemented for producing freshwater in the natural weather conditions of Malaysia. It was found that using two Fresnel lenses instead of a single large one gives a boost to the production of freshwater per unit solar irradiation by 39%. The produced water has a total dissolved solids (TDS) value of 37 ppm, which is well within the drinking water standard range according to the World Health Organization.
