There are two main types of submerged diffused aeration systems for lagoon applications: floating lateral and submerged lateral. Both these systems utilize fine or medium bubble diffusers to provide aeration and mixing to the process water. The diffusers can be suspended slightly above the lagoon floor or may rest on the bottom.
The first floating solar installation was in Aichi, Japan, in 2007, built by the National Institute of Advanced Industrial Science and Technology. [9] [18] In May 2008, the Far Niente Winery in Oakville, California, installed 994 solar PV modules with a total capacity of 175 kW onto 130 pontoons and floating them on the winery's irrigation pond.
Reducing the amount of water used to irrigate livestock feed crops may be critical to revitalizing the dried-out Great Salt Lake, a new study has found. About 62 percent of the river water heading ...
The fenced-off area was then layered with mud, lake sediment, and decaying vegetation, eventually bringing it above the level of the lake. Often trees such as āhuexōtl [aːˈweːʃoːt͡ɬ] (Salix bonplandiana) [3] (a willow) and āhuēhuētl [aːˈweːweːt͡ɬ] (Taxodium mucronatum) [14] (a cypress) were planted at the corners to secure the ...
The results of the litigation culminated with a SWRCB decision to restore fishery protection (stream) flows to specified minimums, and raise Mono Lake to 6,391 feet (1,948 m) above sea level. The agreement limited further exports from the Mono Basin to 16,000 acre⋅ft (19.7 million m 3 ) or less per year during the transition period.
Floating island La Rota in Posta Fibreno lake, Italy. Natural floating islands are composed of vegetation growing on a buoyant mat of plant roots or other organic detritus. In aquatic regions of Northwestern Europe, several hundred hectares or a couple thousand acres of floating meadows (German Schwingrasen, Dutch trilveen) have been preserved, which are partly used as agricultural land ...
Three basic types of subirrigation system are in general use for potted plants in greenhouses: ebb-and-flow (bench-mounted enclosures holding pots are filled and then drained); trough (water is flowed through bench-mounted, slightly sloping enclosures containing pots); and flooded floor (special sloped concrete flooring is flooded and drained).
