Water softners and lime softening are good for issues of hardness and pH. Scale inhibitors can be used.
Flushing with 5 t 8 percent dilute HCl acids a good option for common calcium carbonates.Mn perhaps a greater problem in PVCpipes.Flushing with white vinegar or EDTA for calcium sulphate.
High pressure steamers and jet flushers work well in scaling situations.
Industrial cleaners like Barium nitrate,phosphoric acid and sulfuric acids usually used,appropriately.
High chlorine dose best for biofilm bacterial inhibition.
Interestingly residual chlorine,MAPs and organic carbon combo can contribute to faster biofilm build up
