Point Loma Wastewater Treatment Plant
The Point Loma Wastewater Treatment Plant is a primary waste water treatment facility located on the Point Loma Peninsula in San Diego, California. It is a notable facility due to its ability to treat 1 gallon of waste water for 1/3000th of a penny. The process used to treat the waste water has been perfected to treat a large amount of water as inexpensive as possible. This waste water facility is also noted for its high percentage of removal of pollutants while also remaining a primary treatment facility. The solid removal rate is between 88–90% while the BOD (Biological Oxygen Demand) removal rate is kept at 60%. This unique process involves adding Hydrogen Peroxide in order to retrieve and recycle the iron salts that are used in treatment, thus enabling major cost savings. History and background Prior to the opening of the waste water plant, around 1963, the waste in San Diego was carried through interconnected wooden boxes. These boxes transported the water to the San ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. It has also been detected on other plane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
