Question:
Why are calcium carbonate encrustants minimal on the inside walls of PVC tubes?



Replies:
PVC (Poly Vinyl Chloride) pipe has a very smooth hydrophobic surface so there are not very many sites on the surface for the calcium carbonate deposits to adhere. In contrast, metal pipes have many rough water-loving sites for the deposits to grow.
