Aluminum-Based Water Treatment Residue Reuse

Aluminum-based water treatment residue (Al-WTR) generated during the drinking water treatment process is a readily available recycled material with high phosphorus (P) adsorption capacity. The P adsorption capacity of Al-WTR generated from Singapore’s water treatment plant was evaluated with reference to particle size range, adsorption pH and temperature.

1. Introduction

The main purpose of this study was to recover alum from water treatment residue and use it as flocculants for further water treatment. The experimental results showed that sludge collected from Kimisagara water treatment plant located in Kigali, the capital city of Rwanda contains a significant amount of aluminum (2877.5 mg/l) that could be recovered and be reused as flocculants agent for further use.
