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.
