The application of a single slope solar still in a refinery wastewater treatment: An experimental study

An alternative resource for energy and water has become essential to ensure long-term sustainability. Industrial wastewater is one of the main environmental challenges which could affect one’s life, due to its related pollution. Using solar distillation systems could be the key solution to treating industrial wastewater. In this work, an experimental apparatus was fabricated and tested according to Al-Samawa city climate conditions, to treat the oily-waste water from a refinery. Two different sources of raw wastewater samples with different physical and chemical characteristics were used. Five different runs were performed on different days in November at a sunshine time between (10 AM – 2 PM). The results of the condensate water showed that TDS was reduced by 94 %, conductivity reduced by 95 % and PH increased from an average value of 6.4 to 7.4.
