They used both synthetic and real wastewater. The later wastewater produced from wet phosphoric acid process. The separation of phosphates and fluorides was achieved by two steps; the first one was precipitation of phosphates and fluorides ions by calcium and iron in the presence of aluminum as the complexing agent of the fluoride ions.

The ,acidic, solution has more free hydrogen ,ions, and the alkaline solution has fewer free hydrogen ,ions,. Any substance that lowers pH is an acid and any substance that raises it is a base. Buffers are substances that enable water to resist pH change when an acid or base is added.

Acidic, soils in the Amazon cause many of the lakes and rivers to naturally have low pH values ³⁸. Due to the dissolved humic substances from runoff and uptake, “blackwater” sources can have a pH as low as 4.43. “Clearwater” sources will have a slightly higher, but still ,acidic,, pH value ³⁸.

As the acid water flows through the metal pipes, it leaches the metal ions from the pipes and introduces them to your water supply. This means the water can potentially contain levels of iron, manganese, copper, zinc, and lead. Drinking elevated levels of heavy metals can be toxic, especially lead.
