“…The results showed that the values of pH and EC are decreased with the process of distillation. The results are in agreement with the findings of Gowtham et al 19 and Pollerberg et al 37 They tested the distilled water before and after the process of the collector. It was concluded that the PTSC was recommended as the most suitable technique for the production of distilled water.…”

“…16 The performance of a solar collector can be improved greatly by using the solar tracking system, which concentrates a direct solar beam onto the focal point and it depends on the axis of a solar reflector. 17,18 The researcher has investigated the compression of different tracking modes as reported in Gowtham et al 19 and Okoye et al 20 These studies’ results showed that the two-axis tracking system causes the highest system energy and improves the solar energy contribution. Gustavo et al 21 reported that the using of two-axis solar tracking system consumes more energy than the single-axis tracking system due to the extra control power.…”

The distilled water production by the application of the parabolic trough solar collector technology has its significant importance that still needs further exploration. The current study represents the modification of parabolic trough solar collector, with the using of solar tracking tilt sensor with the continuous water circulation rate of 0.22 kg/s to enhance the productivity of the parabolic trough solar collector, and the tracking system consisting of low-speed 12 V motor units of 0.75 r/min and torque of 50 N m was found suitable for the tracking mechanism. The collector received 476 W/m2 with the highest amount of distilled water up to 6675 ml/h m2 during the months of August and the 121°C temperature was recorded during the experiment. The efficiency was noted 31% for the month of August due to the highest absorbing solar irradiance. It was concluded from the results that the tested values of pH and EC in distilled water were decreased from the initial values with the process of distillation through parabolic trough solar collector. Further, from the results, it was concluded that the PTSC was working efficiently with the highest amount of distilled water with the solar tracking tilt sensor and higher efficiency from 08:00 AM to 16:00 PM during the daytime. Furthermore, recommended by the results of the experiment that the amount of distilled water produced significantly depends on the amount of energy input on the concentrator. At last, the distilled water quality was measured and the results were found acceptable for the standard of the Environmental Protection Agency.

A B S T R A C TA desertic region always suffers from a lack of fresh water in a large portion of its area. In these areas, available water from swamps or ground water wells is brackish water, and it must be purified or distillated. In this paper, we introduce a simple distillation system accompanied with a concentrating unit. This system was assembled and installed with very low costs. Also, paraffin wax was used in this study as phase change materials to absorb heat from the heated water. The concentrating system, which consists of a dish accompanied by a drum as a storage device and pipes assembly fixed at dish focal, was used to heat brackish water. The conical distiller was fabricated to contain PCM under its base to increase the stored energy. Tests were conducted at Baghdad, Iraqi wintertime 2013-2014. The study declares that this system is suitable to desert weathers with acceptable productivity compared with other existing systems. Adding PCM to the concentrating distillation system increased system working hours, increased concentrating efficiency with about 50.47%, increased system heating efficiency with about 157.8%, and increased system productivity with about 783%. Comparing this study with other Iraqi studies and those in literature gave convincing agreement. This study contains valuable information for researchers, industrials, and investors interested in solar water desalination system investment in Iraq and desertic weather countries.
