We are implementing patented technologies that enhance the growth of diatoms, a type of microalgae, by providing them with a source of silica. Diatoms are known for their ability to remove nutrients, such as nitrogen and phosphorus, from water, and by boosting their growth, and can help reduce the growth of harmful algae blooms and improve water quality. And is used in applications such as freshwater and marine aquaculture, lake and pond remediation, and wastewater treatment. 
 
Phycoremediation, on the other hand, is a type of bioremediation that uses algae to remove contaminants from polluted water, soil, or air. It involves the use of photosynthetic microorganisms, such as microalgae, macroalgae (seaweeds), and cyanobacteria, to capture and metabolize pollutants, such as heavy metals, organic compounds, and nutrients, from contaminated environments. Phycoremediation can be implemented in different types of water bodies and soils contaminated with heavy metals or other pollutants, and the biomass produced by phycoremediation can be harvested and used for various applications. 
 
Overall, while both bioremediation and phycoremediation utilize algae to address environmental pollution and is focused on enhancing the growth of a specific type of algae (diatoms) to reduce nutrient pollution in water bodies, while phycoremediation is a more general approach that involves using algae to remove a variety of pollutants from different environments. 
 
Phytoremediation and phycoremediation are two types of bioremediation techniques that use plants and algae, respectively, to remove contaminants from polluted environments. While they share some similarities, they differ in their mechanisms and applications.
