a system and process for the removal of divalent ions from a meg - water stream are presented . the system includes a chemical treatment tank that receives the meg - water stream , means for precipitating the calcium , magnesium , and hydroxide ions that are contained in the meg - water stream , means for discharging the meg - water stream from the chemical treatment tank , and means for recycling the discharged meg - water stream back to the chemical treatment tank or routing it to a solids removal system . the means for precipitating the calcium , magnesium , and sulfate ions may be employed simultaneously or sequentially .
