Phycoremediation is the use of macro-algae or micro-algae ( BIOREMEDIATION) for the removal or biotransformation of pollutants, including nutrients and xenobiotics from wastewater and CO2 from waste air.
What are algae?
A group of aquatic, most primitive photosynthetic organisms ranging from unicellular to multicellular forms and generally possess chlorophyll but lack true roots, stems and leaves characteristic of terrestrial plants.
What is special about micro-algae?
The green-cell factories of microalgae tackle simultaneously more than one problem, a solution not capable by conventional chemical processes. That is, for example, problems such as pH correction, sludge removal, TDS reduction, BOD and COD removal, etc. can be handled simultaneously by micro-algal treatment (phycoremediation), whereas in conventional methods, separate methods or stages of treatments are used
Advantages of algae based technology
We can effectively manage a wide range of industrial effluents to achieve the following:
1. Reduction in COD, BOD
2. Reduction in Sludge
3. More than 90% reduction in operation costs
4. Less space requirment and no chemicals are used
