“…Water is a vital source of life on earth. 7 There is an urgent need for clean, pure, and distilled water in many countries for the use of different purposes. 8,9 Mostly, the water resources are brackish and contain harmful bacterial species and ions, such as Na, Ca, Mg, Zn, and so on, which cannot be used directly.…”

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.

“…Parabolic trough solar collector. This type of collector is used in solar power plants [61]. A trough-shaped parabolic reflector is used to concentrate sunlight on an insulated tube (Dewar tube) or heat pipe, placed at the focal point, containing coolant which transfers heat from the collectors to the boilers in the power station [62].…”

“…In a parabolic dish collector, one or more parabolic dishes focus solar energy at a single focal point, similar to the way reflecting telescopes focuses starlight [63]. The shape of a parabola means that arriving light rays which correspond to the dish's axis will return toward the focus [61]. Light from the sun reaches the earth's surface almost entirely parallel, and the plate aligned with its axis pointing at the sun permits almost all incoming radiation to replicated toward the focal point of the plate [64].…”

The PTC performance was evaluated at four (i.e., 25o, 35o, 45o, and 55o) different adjusting Angles and it clearly showed that the adjusting Angles is highly significant, affecting the efficiency of the collector. The PTC received mean solar radiation 513 kJ.m-2.hr-1 with the absorbing temperature of the absorber in PTC was noted 123oC, 115oC, and 113oC consecutively the months of the year with the adjusting angles of 25o, 35o, and 45o respectively. Distilled water from the solar water distillation unit was found to improve the laboratory’s quality and wash equipment in the hospital. PTC’s efficiency noted 26.9%, 26.3%, and 26.1% with the distilled water up to 217, 313, and 343 ml.m-2.day-1 for the adjusting Angles of 25o, 45o, and 35o respectively. From the result, it concluded that to obtain maximum distilled water, the PTC should be set on adjusting Angles of 25o, 35o, and 45o. The average unit price of distillate from the solar still is assessed as Rs. 2.64/L-m2 with a payback period is 365 days. The unit distillate cost is seen to reduce significantly from Rs. 4.92/L to Rs. 1.57/L. It concluded from results that the distilled water of PTC relatively decent quality.
