  • Patent number: 11130691
    Abstract: Techniques are described for preparing a water filtration composition that includes activated carbon having an ash content of at least 10 wt. % and particles of a solubilizing agent. The solubilizing agent forms a water-soluble complex with cations (e.g., calcium ions). This increases the solubility of calcium ions and other scale-forming ions in water, thus suppressing scale formation on interior surfaces of water processing infrastructure. The activated carbon and the solubilizing agent are processed to have particle sizes in a same range, thus enabling the activated carbon and the solubilizing agent to be thoroughly mixed together.
