The microbial biochemistry of slow sand filters.
… in the amount of water filtered, known as headloss. At Invercannie Water Treatment Works, water from the River Dee is used as the raw intake water as it is of a high quality. However, like all waters from upland sources, it can become discoloured during heavy rainfall due to the presence of …

Effects of Dissolved Gas Supersaturation and Bubble Formation on Water Treatment Plant Performance
… in filter media can block pore spaces and create headloss, a process popularly termed "air binding." During benchscale filtration experiments, bubbles were released upwards from the media in a burping phenomenon, and bubbles could also be pushed downwards by fluid flow. Burping is beneficial since …

Advanced Biofilm and Aerobic Granulation Technologies for Water and Wastewater Treatment
… performed. Another common issue of BAF is the headloss buildup during its operation, which has become a significant energy and maintenance burden at many utilities. Thus, a mathematical model was developed to predict BAF headloss buildup in response to organic removal and nitrification. For …

A Model for Determining Leakage in Water Distribution Systems
… formulation consisting of continuity, energy (headloss), pressure-dependent demands and/or leakage, and flow direction preservation equations are utilized to distribute demand flows and leakage among pipes. The leakage is attributed to the formation of corrosion holes. Based upon the extent of …

Comparing Ferrous Chloride and Ferrous Sulfate as Secondary Coagulants at the Beaver Water District Drinking Water Treatment Plant
… for chlorite quenching at BWD. Notably, the headloss rate during filtration in the pilot plant study was lower for the FS-treated waters at all values of ADR tested, and thus is the recommended secondary coagulant for the BWD. </p>
