This study introduces the new biological reactor that called serial sequencing batch moving bed reactor. In this research, this reactor was used for treatment of hospital wastewater. Furthermore, three independent variables (retention time, pollutant loading and media filling percentage) were investigated. For the first time, modeling of COD removal percentage (as the dependent variable) in hospital wastewater treatment was investigated by using of response surface methodology. According to the results, the COD removal efficiency increased from 58 to 91%, when pollutant loading decreased from 0.38 to 0.3 kgCOD/kgMLSS. Also, COD removal efficiency increased from 38 to 86% when retention time increased from 16.48 to 58.52 h. According to the results, the media filling percentage had the minimum effect on the COD removal efficiency, so that, COD removal efficiency increased from 63 to 78% with increasing in media filling percentage from 19.77 to 45%. The results revealed that the optimum condition to achieving the highest COD removal efficiency was at the retention time of 46.59 h, pollutant loading of 0.34 kgCOD/kgMLSS and media filling percentage of 42.24%. According to this research results, this reactor have high efficiency in hospital wastewater treatment.
Psychological First Aid (PFA) and FEMA crisis counseling services (CCP) are becoming more prevalent for post-disaster mental healthcare, but they are intended only for short-term support. Many survivors will thus needlessly endure lengthy suffering from severe illnesses such as post-traumatic stress disorder (PTSD). After the Federal Emergency Management Agency (FEMA) was established in 1979, most American communities developed emergency plans to provide survivors with medical care immediately following a disaster. Although calamities also emotionally traumatize about 20% of victims for long periods of time, few of these same communities have established preparedness plans for disaster mental health interventions. To offer maximum wellbeing, communities need to effectively assess and respond to the mental health needs seriously arising, as well as develop psychological preparedness plans that will immediately address further long-term problems from worsening natural and human-caused events.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
