Abstract
The invention is a water wheel supplying energy to a pump. The pump will typically be used to apply chemical treatments to the water stream. Some examples of chemicals to be added are acids or bases to bring the pH to an acceptable level, precipitation aids for suspending metal out of water, coagulants to aid in filtering dissolved solids out of water, flocculants to aid in filtering dissolved ions out of water, chlorine, or coloring to prevent growth of algae.
