A trial to adopt biomineralization to reduce
Ca content in the form of aragonite was executed in a hypersaline pond site, Lake Qarun,
Fayium. The separated crystals from the mineralized biomasses indicate formation of pure
aragonite crystals of different sizes. This environmentally safe process is proved
efficient to reduce the Ca content and matches the changes in the chemical composition of
Lake Qarun (increase in Ca content) recently. This has also an application in different
industrial fields. |
