Membrane Fouling Mitigation with Water Hammer
… its widespread application has been limited by fouling. Fouling results in a decline in membrane performance and requires regular chemical cleaning to sustain the operation. This thesis focuses on the development of a new approach to mitigate fouling by subjecting a membrane to water hammer. The …

Diffuser Fouling Mitigation, Wastewater Characteristics And Treatment Technology impact on Aeration Efficiency
… costs. A pilot scale study of fine pore diffuser fouling and mitigation, quantified by dynamic wet pressure (DWP), oxygen transfer efficiency and alpha measurement were performed at Blue Plains, Washington DC. In the study a mechanical cleaning method, reverse flexing (RF), was used to treat two …

FOULING AND ITS MITIGATION ON HEAT EXCHANGER SURFACES BY ADDITIVES AND CATALYTIC MATERIALS
Calcium carbonate (CaCO3) fouling is the most commonly observed fouling phenomenon in cooling water applications. Fouling happens when a process uses cooling water supersaturated with mineral salt crystals (i.e. hard water). Precipitation deposits on heat transfer surfaces whenever these …
