Tile, tile, on the wall... Who's the most abrasion resistant of them all?
A wastewater treatment plant installs abrasion-resistant tiles inside 24 cyclones to prevent abrasive wear and lengthen their operating life.
The Milwaukee Metropolitan Sewerage District (MMSD), Milwaukee, treats wastewater from the Milwaukee metropolitan area and surrounding municipalities at the Jones Island Wastewater Treatment Plant, located along Lake Michigan on a peninsula in Milwaukee’s harbor. More than 100 million gallons of wastewater are conveyed to the Jones Island plant each day, where it's treated, cleaned, and purified before being discharged into Lake Michigan. MMSD processes the solids from the wastewater into a commercial fertilizer. After building a new solids drying and dewatering facility for the fertilizer production process, MMSD noticed that the cyclones installed to remove airborne dust from the dryers' exhaust air were showing signs of wear on their interior walls. MMSD needed to find a way to prevent this problem.
