Uniform National Discharge Standards
In the United States, several federal agencies and laws have some jurisdiction over pollution from ships in U.S. waters. States and local government agencies also have responsibilities for ship-related pollution in some situations. International laws and regulations MARPOL 73/78 (the "International Convention for the Prevention of Pollution From Ships") is one of the most important treaties regulating pollution from ships. Six Annexes of the Convention cover the various sources of pollution from ships and provide an overarching framework for international objectives. In the U.S., the Convention is implemented through the Act to Prevent Pollution from Ships (APPS).Act to Prevent Pollution from Ships, . Under the provisions of the Convention, the United States can take direct enforcement action under U.S. laws against foreign-flagged ships when pollution discharge incidents occur within U.S. jurisdiction. When incidents occur outside U.S. jurisdiction or jurisdiction cannot be de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liter
The litre ( Commonwealth spelling) or liter ( American spelling) (SI symbols L and l, other symbol used: ℓ) is a metric unit of volume. It is equal to 1 cubic decimetre (dm3), 1000 cubic centimetres (cm3) or 0.001 cubic metres (m3). A cubic decimetre (or litre) occupies a volume of (see figure) and is thus equal to one-thousandth of a cubic metre. The original French metric system used the litre as a base unit. The word ''litre'' is derived from an older French unit, the '' litron'', whose name came from Byzantine Greek—where it was a unit of weight, not volume—via Late Medieval Latin, and which equalled approximately 0.831 litres. The litre was also used in several subsequent versions of the metric system and is accepted for use with the SI, despite it not being an SI unit. The SI unit of volume is the cubic metre (m3). The spelling used by the International Bureau of Weights and Measures is "litre", [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fecal Coliforms
A fecal coliform (British: faecal coliform) is a facultatively anaerobic, rod-shaped, gram-negative, non- sporulating bacterium. Coliform bacteria generally originate in the intestines of warm-blooded animals. Fecal coliforms are capable of growth in the presence of bile salts or similar surface agents, are oxidase negative, and produce acid and gas from lactose within 48 hours at 44 ± 0.5°C.Doyle, M. P., and M. C. Erickson. 2006"Closing the door on the fecal coliform assay."'' Microbe'' 1:162–163. . The term thermotolerant coliform is more correct and is gaining acceptance over "fecal coliform". Coliform bacteria include genera that originate in feces (e.g. ''Escherichia'', ''Enterobacter'', '' Klebsiella'', '' Citrobacter''). The fecal coliform assay is intended to be an indicator of fecal contamination; more specifically of '' E. coli'' which is an indicator microorganism for other pathogens that may be present in feces. Presence of fecal coliforms in water may not be di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Sanitation Device
A marine sanitation device (MSD) is a piece of machinery or a mechanical system that is dedicated to treat, process, and/or store raw, untreated sewage that can accumulate onboard water vessels. It does not refer to portable devices such as portable toilets.

Toilet
A toilet is a piece of sanitary hardware that collects human waste (urine and feces) and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank. The waste is known as '' blackwater'' and the combined effluent, including other sources, is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet. " Toilet" or "toilets" is also widely used for rooms containing only one or more toilets and hand-basins. Lavatory is an older word for toilet. The technolo ...

Clean Boating Act Of 2008
The Clean Boating Act of 2008 (CBA) is a United States law that requires recreational vessels to implement Best management practice for water pollution, best management practices to control water pollution, pollution discharges. The law exempts these vessels from requirements to obtain a discharge permit under the Clean Water Act (i.e. they are exempt from coverage under the EPA Regulation_of_ship_pollution_in_the_United_States#Vessels_General_Permit, Vessels General Permit). The CBA amended the Clean Water Act (CWA) and directs the U.S. Environmental Protection Agency (EPA) to develop performance standard regulations. The regulations will not apply to sewage discharges from recreational vessels, which are already regulated under the CWA. (''See'' Marine sanitation device.) The CBA designated the U.S. Coast Guard as the enforcing agency. In 2011 EPA conducted public meetings to obtain public comment about developing CBA regulations.EPA.

Best Management Practice For Water Pollution
Best management practices (BMPs) is a term used in the United States and Canada to describe a type of water pollution control. Historically the term has referred to auxiliary pollution controls in the fields of industrial wastewater treatment, industrial wastewater control and sewage treatment, municipal sewage control, while in stormwater management (both urban and rural) and wetland management, BMPs may refer to a principal control or treatment technique as well. Terminology Beginning in the 20th century, designers of industrial and municipal sewage pollution controls typically utilized sewage treatment, engineered systems (e.g. Trickling filter, filters, clarifiers, Bioreactor, biological reactors) to provide the central components of pollution control systems, and used the term "BMPs" to describe the supporting functions for these systems, such as operator training and equipment maintenance. Stormwater management, as a specialized area within the field of environmental engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Graywater
Greywater (or grey water, sullage, also spelled gray water in the United States) refers to domestic wastewater generated in households or office buildings from streams without fecal contamination, i.e., all streams except for the wastewater from toilets. Sources of greywater include sinks, showers, baths, washing machines or dishwashers. As greywater contains fewer pathogens than blackwater, it is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation, and other non- potable uses. Greywater may still have some pathogen content from laundering soiled clothing or cleaning the anal area in the shower or bath. The application of greywater reuse in urban water systems provides substantial benefits for both the water supply subsystem, by reducing the demand for fresh clean water, and the wastewater subsystems by reducing the amount of conveyed and treated wastewater. Treated greywater has many uses, such as toilet flus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cathodic Protection
Cathodic protection (CP; ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded " sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current. Cathodic protection systems protect a wide range of metallic structures in various environments. Common applications are: steel water or fuel pipelines and steel storage tanks such as home water heaters; steel pier piles; ship and boat hulls; offshore oil platforms and onshore oil well casings; offshore wind farm foundations and metal reinforcement bars in concrete buildings and structures. Another common application is in galvanized steel, in which a sacrif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
