Tina Arrowood begins her keynote by sharing her own personal connection to the Mississippi River and her passion for protecting rivers. Salt pollutes river water and Arrowood outlines that river water is a precious resource that is drastically undervalued. If salt is added to the river water, the river can become polluted and changed.
Arrowood outlines three defense mechanisms that can be used to protect rivers. The first is ‘Water Recycle & Reuse’, which means that less water is taken from rivers and that the extracted water is recycled. The second defense mechanism is ‘Salt Recycle & Reuse’, where salt can be extracted and reused from industrial water. The third mechanism is ‘educated recycled salt users’, where salt consumers buy recycled salt instead of salt from mines.
Arrowood further states that membrane technology can be used to strengthen the first two defense mechanisms. Membrane technology is able to separate wastewater into salt and fresh water. Tina Arrowood further emphasizes the importance of converting salt consumers and developing the circular salt economy.
