Sustainable Removal of Iron Clogging in Boreholes
Iron (lll) clogging has been removed with various acids and combinations for centuries. pH-neutral reducers; however, exceed 50 times the dissolving capacity of hydrochloric acid at pH1 in an identical molar concentration. Removal of this iron by acids requires pH-values of <1 before significant amounts are dissolved. By reacting first with other minerals surrounding the boreholes, they cause cavities and irreversible damage. You will learn about a low pressure injection technique that has proven efficiency for decades. The dissolution process is controlled by continuous measurements of conductivity and reaction products. A presented case study will document a sustainable rehabilitation of 37 wells supplying an industrial plan in Germany. Results of previous rehabilitations were more than doubled; saving >70% of the budget.
