Deposition of Hematite from Flowing Suspensions onto Aluminum and Polypropylene Pipe Walls

A set-up has been built to study the deposition of hematite on pipe walls of a circulating water loop. The circuit tubing was made of polypropylene, with an exchangeable test section of boehmitized aluminum.

Description
Summary:A set-up has been built to study the deposition of hematite on pipe walls of a circulating water loop. The circuit tubing was made of polypropylene, with an exchangeable test section of boehmitized aluminum. Real-time turbidimetric measurements of particles concentration remaining in suspension, led to the amount of deposited hematite. The influence of suspension pH on the deposition process has been investigated under turbulent flow, Re 15600. Results were discussed in light of the surface properties of used materials: hematite, polypropylene, and aluminum. A good agreement between experimental data and DLVO predictions was found; a significant deposition occurred in the pH where hematite and aluminum surfaces were oppositely charged.
