Beschreibung
Zusammenfassung:	Disclosed herein is a controlled method of minimizing radioactive sludge generation in treatment of wastewater from an oil and/or gas well. The method comprises measuring a concentration of a radioactive material in wastewater to be treated and measuring a concentration of barium in the wastewater to be treated. The method further comprises adding a calculated quantity of sulfate to the wastewater to be treated sufficient to precipitate a quantity of barium sufficient to reduce the concentration of the radioactive material to a level such that sludge precipitated in a secondary precipitation has a radiation level below a defined radiation level.
