| titleOfInvention | Biocidal compositions for treating water |
| abstract | The present invention is directed to a biocidal water treatment composition, water treatment apparatus, and method of treating water to reduce levels of pathogens. The composition contains sources of copper, zinc , and silver metal ions within a cross-linked polymer matrix. Examples of these ion sources include copper sulfate, zinc sulfate, and silv er nitrate. An example of the cross-linked polymer matrix is cross-linked chitosan, which also serves to clarify the water and release th e metal ions over time. The product is easy to manufacture, and allows the use of decreased halogen sanitizer, as well as decreased copper ion, thereby decreasing the likelihood of staining. The product simultaneously provides good bactericidal and algaecidal properties, despite low levels of copper ion and low chlorine levels. |
