AI Technical Summary

Benefits of technology

This patented technology makes mixed carriers from different types of chemical agents like platyclay or polypyrrole (PP), allowing for wider ranges of materials used without compromising their quality. These mixtures are combined together into one structure called an alginate gel/fiberglass mixture. By mixing these ingredients, they form strong structures containing various compounds such as calcium hydroxides, magnesia, etc., making them suitable for applications where heavy loads should be supported over longer periods. Additionally, this hybrid system provides excellent physical characteristics including flexibility, durability, and efficacy under varying environmental conditions. Overall, this new type of biological film support material offers superior benefits compared to existing methods while maintaining its original qualities.

Problems solved by technology

This patents describes different types of material used during treating bacteria-containing waste waters such as glass sands or cokes. These materials can be harmful if they get stuck inside other parts of equipment due to their low surface areas with weaknesses like rocks or porcelain tiles. Plastonium also has been found safe but less effective than traditional methods because its chemical properties make them difficult to dissolve when mixed with certain substances commonly added by septic tank operators who use this method.
