| Abstract | The present paper describes the evaluation of the reactor/clarification system that was used to treat the heat depleted geothermal brine at MCR Geothermal' Mercer 2 well site prior to reinjection. This was done through the monitoring of suspended particles in the brine downstream of the various components of the reactor/clarification system. the particle measurements were made by using four different techniques. The results showed that most of the suspended particle formation occurred at the reactor. The "dissolved" silica concentration in the brine downstream of the reactor is found to be undersaturated. The undersaturation is probably caused by the precipitation and removal of some of the silica as iron silicate. The filer installed downstream of the reactor/clarification system worked very well and is suitable for brine treatment prior to reinjection. |
