Chapter 1: Techniques

Krill-Based Techniques for Environmental & Water Treatment

This chapter focuses on the specific techniques and methodologies leveraging krill's unique abilities for environmental and water treatment.

• Biofiltration: Krill's efficient filter feeding system can remove excess nutrients (e.g., nitrates, phosphates) and pollutants (e.g., heavy metals, microplastics) from water bodies. This biofiltration technique can be applied to both open water ecosystems and closed systems like aquaculture ponds.
