This was achieved by the NaOH discharge (pH 14 and approximate concentration of 10 kg/m 3, i.e. 1%). Thus, the desired pH of 13 was achieved with an approximate flow of 1.5 m 3 /h of this discharge. According to this, the amount of (NH 4) 2 SO 4 produced would be 0.41 x 132 = 54.12 kg/h.

The resulting wastewater contains fluorides and phosphates in hazardous forms. Its treatment ordinarily does not result in a Zero-Liquid Discharge (ZLD) process. To achieve this purpose, several reagents were tested, focusing on the correlation linking pH, type of reagent and the effect on the separation of fluorides and phosphates from the wastewater.
