AI Technical Summary
Technical Problem
Existing water treatment systems, such as those described in Patent Document 1, do not adequately address the decolorization of water after biological treatment, which is crucial for reducing user resistance to reusing treated water.
Method used
A water treatment system that includes a biological treatment unit, an alkali addition unit to maintain a pH below 9, and an ozone treatment unit to enhance decolorization, with alkaline substances like sodium hydroxide, and a control mechanism to adjust alkaline substance addition based on treated water color.
Benefits of technology
The system effectively decolorizes water post-biological treatment, ensuring the treated water meets user acceptance criteria by maintaining low color levels and minimizing microbial activity disruption.
