Efficiency of one scale inhibitor on calcium carbonate precipitation from hot water sanitary: effect of temperature and concentration [PDF]
Heliyon, 2021 The scaling of hot water transport pipes has become one of the major problems encountered in Agadir's region, which exploits water of underground origin with very high hardness (40°F). Several methods can be used to prevent this phenomenon.
