In some plants, disinfection is also done with the help of ultraviolet radiation. The collected liquid is discharged to overboard or settling tank depending on the geological position of the ship. If the ship is in restricted or near coastline then the sewage will be discharged into the holding...

Sewage sludge is the final product of a Publicly Owned Treatment Works (POTW) also called "wastewater treatment plants," wastewater treatment systems," or "sewage treatment plants." After treatment breaks down the organic matter and kills disease-causing organisms, the remaining fine particles ultimat...
One might wonder whether variable transport lengths from households to treatment plants affect the measured resistome. Pehrsson et al. found that street-access sewage resistomes were very similar to downstream WWTP influent, while both sample types were compositionally different from human feces and sewa...
Sewage treatment plants (STPs) generally have a sequence of discrete unit processes with different treatment mechanisms, typically combining solids separation and biological oxidation. Removal of APIs in STPs is therefore determined by the treatment processes utilized and the physicochemical properties and ...
Acute effects on adult copepods of sludge from 3 treatment plants were seen at concentrations ranging from 0.03 to 0.8 % whole sludge in the water (Miller et al. 1987). In this experiment sludge was added at rates which could have achieved 0.03 % whole sludge after 9 d of addition to ...
It is used and washed down the drains into wastewater. From our lab in Baltimore, we followed wastewater pipes to the nearest treatment plant and found triclocarban not only in the water entering the plant, but also in urban streams near leaky sewer pipes and in the process flows exiting the...
