Green roofs are emerging home improvement technologies that can provide a wide range of tangible and intangible benefits to communities interested in enhancement of their environment. Green roof development involves the construction of a vegetative layer on top of a human-made structure or building adding green spaces to areas that would otherwise be unused. The […]
Green roofs can provide a wide range of benefits to urban communities interested in enhancement and protection of their environment. Some of the most important merits of green roofs are reduction in energy use, decrease in air pollution, improved water quality, enhanced stormwater management and decreasing heat island effect. Let us explore the benefit of green […]
If small enough, or even microscopic bubbles are achieved, as is possible with Aeration Turbines, supersaturation takes place – where oxygen levels are pushed beyond their natural limits. In normal circumstances, water will automatically drop oxygen levels back to their natural threshold, so there seems to be no point in doing this. The combination of […]
Biogas basically consists of methane and carbon dioxide. In addition, it also contains unwanted contaminants, especially hydrogen sulfide (H2S). Hydrogen sulfide mainly occurs because of the degradation of sulfur-containing proteins (e.g. methionine and cysteine) or the desulfurization of sulfates. The fermentation of manure and other organic wastes shows typical H2S concentrations in the range of […]
There is a method to increase precipitation called “Cloud seeding”. Artificial rain by utilizing sunlight – Hadley microcell – is another interesting approach for creating artificial rain. Hadley cell is a natural phenomenon and part of Hadley cell close to the equator receives rich precipitation. Why rain happens? There are several mechanisms of creating precipitations […]
