Inhibition of the geothermal water’s scale in the south of Tunisia, effect of temperature
Written by sctunisie no commentsCharacteristics of geothermal waters from the South of Tunisia are described. Their high hardness has disastrous consequences. Chronoelectro-gravimetry allows an evaluation of their scaling tendancy. It is shown that sodium tripolyphosphate at very low concentration (0.8 mg.l-1 that is 2.2 µmol.-1) inhibits totally calcium carbonate precipitation at 60°C.
