Frontiers

The optimization of enzyme-mediated calcite precipitation (EMCP) was evaluated as a soil improvement technique. In our previous works, purified urease was utilized to bio-catalyze the hydrolysis of urea, which causes the supplied Ca2+ to precipitate with CO32- as calcium carbonate. In the present work, magnesium chloride was newly added to the injecting solutions to delay the reaction rate and

Acidic Water

Calcite treatment raises the pH by adding calcium carbonate to the water. This has the sometimes undesirable effect of increasing the hardness of the water slightly. Calcite and corosex are most commonly used in backwashing filters, but calcite alone can be used with simple upflow filters if the water is reasonably clean. Calcite is also commonly used in cartridge form as a postfiltration treatment for

What Is Calcite?

Calcite is a rock forming mineral with a chemical formula CaCO 3. Many sea organisms such as coral, algae and diatoms make their shells out of calcite, they pull carbon dioxide from the sea water to accomplish this. Environmentally, calcite is very important and has played a key role in the successful development of early Earth.
