Carbon Dioxide → Calcium bicarbonate

関与物質

反応手順

When calcium carbonate is supplied to contaminated water for stirring and mixing therewith and thereafter carbon dioxide is admixed with the contaminated water, calcium carbonate reacts with carbon dioxide to form calcium bicarbonate which tends to dissolve in water, whereby reduced amount of sludge will be produced after purification of contaminated water. When calcium carbonate is used during introduction of exhaust gas into the purification system, calcium carbonate will react with carbon dioxide in the exhaust gas to be dissolved in water as calcium bicarbonate.
