This slide presentation outlines information on line diffusers, a free bubble hypolimnetic
diffuser system designed to place oxygen in specific
layers and areas of the reservoir to achieve
optimized dissolved oxygen (DO) enhancement.
Oxygen bubbles are spread over large areas to obtain
high oxygen transfer efficiencies and minimize vertical
mixing.
Diffusers up to a mile long are utilized to spread
oxygen input into the reservoir and
are located at specific elevations above the
reservoir bottom.
Oxygen outflow distribution along the length of the
diffuser is controlled with engineered orifice sizes. Oxygen supply for the diffusers is outlined, along with sources for supplying gas and previous applications that include: Los Vaqueros Reservoir
Contra Costa County Water District
Livermore, California 2000; Upper San Leandro Reservoir
East Bay Municipal Utility District 2001; Lake Wallenpaupack
PPL Generation Services
Hawley, Pennsylvania 2004; Carvins Cove Reservoir
Western Virginia Water Authority
Roanoke, Virginia 2005; and, Calaveras Reservoir
San Francisco Public Utility Commission
Milpitas, California 2005. Includes figures.
