Abstract: | Scaling is a common problem in domestic, commercial and industrial process where water is used. One of the most effective methods of controlling crystallization fouling is the addition of chemical inhibitors to potentially scaling waters. For reducing calcium carbonate scale formation different concentrations of polyacrylate (RPI2000) was added. The results show that this inhibitor is capable of inhibiting the formation of limestone deposit and inhibits the scale formed on the walls. Calcite growth rate is reduced and the inhibiting effect occurs at very low concentration. The precipitation ratio (τ) reached 0%, therefore a reduction of 24% compared to the raw water. This inhibitor extends the degassing phase. IR analyses demonstrated modifications in crystalline structure. |
