water-treatment
Water treatment is the process of removing contaminants and improving water quality for specific end-uses. For plant science, treated water is critical in research, cultivation, and irrigation applications, as water quality directly impacts plant health and the validity of experimental results. This is especially important in aquatic plant research and controlled systems like hydroponics, where precise water chemistry management is essential.

Researchers found that a marine diatom can remove 'forever chemicals' (PFOA and PFOS) from water, eliminating about 25-29% of these persistent pollutants over 15 days through a process that follows predictable first-order kinetics, offering a potential low-cost biological approach for contaminated water treatment.
Chaetoceros calcitrans removed 24.65% of PFOA and 29.35% of PFOS at initial concentration of 100 μg/L within 15 days
Removal kinetics followed first-order models with rate constants (k) of 0.014-0.019 day⁻¹
