| Abstract | A large fraction of the low pressure domestic bores in Rotorua suffer from calcite scaling. The problem is sometimes so severe, that wells have to be mechanically reamed every six weeks. We havetested the use of threshold antiscalants to control the calcitede position. The experiment ran for over eight months and there is no sign of any calcite buildup, eitheri n the well or in the surface pipework. Previously, the well had required reaming every three months. |
