Abstract
Methods and systems are provided for removing calcite deposits by contacting polysuccinimide with water to dissolve the polysuccinimide and supplying the dissolved polysuccinimide to surfaces fouled with the calcite deposits. The pH of the water that dissolves the polysuccinimide can be adjusted based on the amount of calcium in the water. Adjusting the pH will affect the dissolution rate of the polysuccinimide in water and the rate of removal of the calcite deposits.
Claims10
A system for treating surfaces fouled with calcite, the system comprising:
- a remediation water stream that includes a stream bed with the surfaces fouled with calcite;
- a split stream that has an influent supplied by the remediation water stream and an effluent that is fed back to the remediation water stream at a plurality of locations;
- a feed source of solid polysuccinimide that is contacted by water from the split stream to dissolve the polysuccinimide so that dissolved polysuccinimide is supplied from the split stream to the remediation water stream at the plurality of the locations;
- a calcium probe that is configured to measure an amount of dissolved calcium in the remediation water stream and/or split stream;
- a pH probe that is configured to measure the pH of the remediation water stream and/or split stream;
- and
- an alkali source that is configured to supply an alkali reagent to the split stream,
- wherein the system is configured so that an amount of the alkali agent that is supplied is based on at least the measured amount of dissolved calcium.
