These have the ability to impact the environment as well as the water quality used by humans and industry. This investigation establishes a complete, consistent framework for modeling the condensation of industrial waste after it has been discharged and kept in an evaporation pond. Solar stills are utilized to cleanse industrial wastewater using evaporation ponds as a case study. This method is designed for small, straightforward installations in off-grid regions having access to both salty wastewater and renewable energy sources. Desalination is therefore one of the most efficient means of supplying industry and agriculture. Among the potential energy systems is the technology for concentrating solar electricity.

Utilizing a concentrating system is useful due to its low-cost design, easily accessible components like as mirrors and receiver tubes, and compatibility with fossil fuel technologies to construct a hybrid system. One of the focusing ways that can create enormous amounts of power and heat applications constitute a parabolic trough collector (Lippke, 1996; Kalogirou, 2002) With the proper parabolic trough concentrating solar system (PTCSS) design, low, medium, and high- temperature applications are achievable. To create hot water, design and build a parabolic trough collector with a smooth 90° rim angle and fibreglass reinforcement. According to studies on five parabolic trough solar collectors with varying rim angles employed in a low enthalpy process, maximum efficiency of 67% and temperature of around 110°C may be obtained at a rim angle of 90° (ValanArasu and Sornakumar, 2007; Jaramillo et al., 2013).
