Certain types of modified zeolites can be applied to heavily polluted water to bind nitrogen.

Zeolites have a porous structure and are used in industry as absorbents. For water treatment, they are applied to a water body with other remediation products, such as Phoslock, to target nutrients.

Nitrogen is another important food source for the growth of harmful algae. By significantly reducing the concentration of phosphorus and nitrogen in a water body, the quality of the waterway will improve to return the aquatic system back to health.
