Extraction of drinking water from modified inclined solar still incorporated with spiral tube solar water heater

Modified Inclined Solar Stills in passive (PISS) and active mode (AISS) were fabricated and researched in the environmental condition of Chennai, India. In an AISS, Spiral Tube Collector (STC) has been integrated for the extraction of drinking water. The major intention of the current research is to estimate the performance of the PISS and AISS for extracting fresh water from brackish water. The highest distilled water production from the PISS and AISS is 4.4 and 8.3 kg/day, respectively. Furthermore, water quality analysis for brackish water has been carried out. The obtained pH value of the brackish water is 8.7 and for fresh water are 7.6. The water qualities meet EPA standards.
