First steps in microbiological calcium removal from calcium-rich industrial wastewater.
A novel application for the process of microbial carbonate precipitation (MCP) was developed. It facilitates the removal of soluble calcium from calcium-rich industrial wastewater. It was shown that via the urea hydrolysis pathway, mediated by autochthonous bacteria, calcium removal exceeding 90% could be maintained in a semi-continuous reactor system.
