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.
Maceration can be achieved by using a chopper pump in the sewage lift station or at the wastewater treatment plant. [1] When the flush is triggered, wastewater flows into the macerator, and when the water level rises, pressure activates the unit, causing the stainless steel blades to rotate at 3,600 rpm, pulverizing the wastewater into fine ...
Sewage treatment plant (a type of wastewater treatment plant) in La Crosse, Wisconsin. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment.
An aerated lagoon (or aerated pond) is a simple wastewater treatment system consisting of a pond with artificial aeration to promote the biological oxidation of wastewaters. [1] [2] [3] [4]
[2]: 180 Some industries install a pre-treatment system to remove some pollutants (e.g., toxic compounds), and then discharge the partially treated wastewater to the municipal sewer system. [3]: 60 Most industries produce some wastewater. Recent trends have been to minimize such production or to recycle treated wastewater within the production ...
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

Third generation UASB reactors, the ECSB reactor. This is a double layer high load system, with 2 settler layers. The upflow rates are high below the first settler layer, and low below the second settler layer - this keeps both the 'adult' and 'baby' grains in the system, which pays off in greater net growth of granular sludge.
