The goal of the research is to create a type of biochar from the waste of olive fruits, and to study its effect in treating the sulfurous water of the hot springs in the state of Samail in Oman.
The following questions were asked:
1. How can we make biochar from olive waste?
2. What is the impact of using biochar from olive waste in treating sulfurous water?
To answer these questions, cooperation was made with some laboratories and research centers at Sultan Qaboos University, and the water protocol was applied to the study samples to measure transparency, acidity, conductivity, and salinity, and to analyze some special components. In water samples before and after mixing with biofuel in the Applied Analysis Unit at the College of Science at Sultan Qaboos University.
The results indicated the possibility of making biochar from olive waste through a special oven in which the olives were subjected to a temperature of 400◦C in the process of slow pyrolysis. Adding charcoal to sulfurous water contributed to reducing acidity and absorbing aluminum (Al) to zero. The results also showed that the percentage of potassium (K) increased at a significant rate after adding biochar.
