Benefits of technology

This technology helps monitor both natural waters (such as rivers) with high levels of nutrients like nitrogen or sulfur fertilizers that may harm aquatic life such as fish). It also includes devices for measuring specific substances called phosphonium compounds found naturally throughout nature by analyzing their chemical structure. These technologies help predict pollution caused by these sources while minimizing environmental impacts on human health.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the efficiency at removing harmful substances from wastewater during city sewerages processing operations without requiring excessive human labor input. Current methods involve chemically treating polluted waters with various types of agents that help remove unwanted materials while minimizing environmental impact on aquatic organisms. These techniques can be expensive because they require frequent reagent addition for each batches being treated.
