Introduction The terms sewage, sludge, municipal wastewater, and others related to the collection and disposal of human and industrial wastes almost automatically “trigger” a negative reaction by the general public, due primarily to the odors that are coincidental to the transport and treatment of wastewater. I t is probably true that every sewage collection system and treatment plant has encou...

Data collection is one of the main research topics of wireless sensor networks in recent years, and, data collection research outside users through wireless sensor networks to collect perception data from the monitoring area. Formal concept analysis is a data analysis tool, especially for investigation and treatment can be given information to discover important information hidden in the data b...

Enhanced bio-hydrogen production from protein wastewater by altering protein structure and amino acids acidification type via pH control was investigated. The hydrogen production reached 205.2 mL/g-protein when protein wastewater was pretreated at pH 12 and then fermented at pH 10. The mechanism studies showed that pH 12 pretreatment significantly enhanced protein bio-hydrolysis during the subs...

The implementation of wireless sensor networks (WSNs) for wastewater treatment plant monitoring and control is rare in the literature. Nevertheless, there seem to be some good reasons for considering this application, since WSNs can easily supply several point measurements and keep track on a single variable over a wide area. This report describes a merged simulator, which is a fusion between a...

Kinetics and stoichiometry of aerobic chemical and biological sulfide oxidation in wastewater from sewer networks were studied. In this respect, the effects of temperature and pH were investigated in the ranges 10 to 20 degrees C and 5 to 9, respectively. The temperature dependency of sulfide oxidation kinetics was described using an Arrhenius relationship. The effect of pH on the rate of chemi...

  Current World Health Organization and Centers for Disease Control and Prevention guidance for the disposal of liquid waste from patients undergoing treatment for Ebola virus disease at hospitals in the U.S. is to manage patient excreta as ordinary wastewater without pretreatment. The potential for Ebolavirus transmission via liquid waste discharged into the wastewater environment is currently...

Municipal wastewater treatment facilities are considered to be "hotspots" for antibiotic resistance, since they conjoin high densities of environmental and fecal bacteria with selective pressure in the form of sub-therapeutic concentrations of antibiotics. Discharged effluents and biosolids from these facilities can disseminate antibiotic resistant genes to terrestrial and aquatic environments,...
