The Basics of Sewage Treatment and Disposal Treatment of domestic sewage is generally a successive multi-step process employing physical, biological and chemical treatment steps that may be classified into several ‘levels’. Primary treatment includes physical separation of large materials via grating or...
The Eslan type sewage treatment plant, also known as zero discharge system has an initial reception chamber in which separation of liquid and solid sewage takes place. Wastes drop onto a moving perforated rubber belt (driven by an electric motor) which the liquid passes through but solids travel...
As we go back to basics,we might recall that it was on this date in in 1874 that Lewis H. Latimer received his first patent (U.S. Patent 147,363), for an improved water-closet for railway cars. Latimer went on to develop an improved process for manufacturing carbon filaments for light...

The obtained results were compared with the pollutant loads discharged at the same time from the sewage treatment plant (STP). In addition, the article assesses possible improvement solutions to reduce the negative impact of storm overflows on water....
Methods Samples for bacteriophage isolation, bacteria, and growth media. Raw sewage samples were collected at the Gdansk Wastewater Treatment Plant (Gdansk, Poland). The physicochemical parameters were provided by the Laboratory of Gdansk Wastewater Treatment Plant (Gdansk, Poland). Clinical strains ...
Plant biomass and its quality parameters—chlorophylls and carotenoids content The fresh and dry aboveground (AGB) biomass showed no significant statistical difference between all experimental treatments, due to the high variability in the biomass yield between the replicates within each treatment. It was...
SS was supplied by the Gujing group wastewater treatment plant located in Bozhou, Anhui Province, China. The moisture and ash contents of SS (dry matter) are 85.2% and 38.7%, respectively. Perfluorooctanoic acid (PFOA), citric acid, and other chemicals are analytical grade and were directly us...
Materials Sewage sludge was obtained from wastewater treatment plant in Pocheon, South Korea. The sample was homogeneously mixed and dried at 105 ◦C for 24 h. The samples were then ground into powders and sieved into separate sizes before torrefaction. 250–355 µm size was selected for ...
