The water treatment industry thrives in Israel because of a lack of water for agriculture and human use.
These capsules from Israel-based AqWise attract bacteria in wastewater. The bacteria then break down contaminants in the water. The squiggly surface area inside the capsules lets the bacteria grow densely.
Without the capsules, water treatment utilities need to build extra disinfecting ponds. The capsules were originally designed to release fertilizer, but AqWise found a more profitable use for them.
