Latest Patents

Kawaziri's most notable patents include a revolutionary sewage treatment system designed to efficiently purify sewage by utilizing floating filter media. These systems utilize a floating filter medium to effectively filter solid components from the sewage. In the first patent, the sewage flows upward in the treatment tank and is filtered through a layer of mesh cylindrical floating filter media that has a lower specific gravity than the sewage itself. To maintain optimal filtration performance, air is jetted from dedicated air jetting pipes, generating a circular flow that removes solid components adhering to the filter medium. The system effectively discharges the cleaned waste to the outside of the treatment tank while maintaining airflow for continuous cleaning.

The second patent focuses on a similar sewage treatment system with air jetting means that enhances cleaning efficiency. This design also enables the sewage to flow upward through the treatment tank, using meshy cylindrical floating filter media for effective filtration. By employing air jetting techniques from air jetting pipes, solid components are scaled off the filter medium, ensuring optimal filtration is maintained throughout the process.
