Design and management of a sewage pit through discrete-event simulation

Abstract

This paper reports two discrete-event simulation studies to model the activities of a residential waste treatment facility and prepare it to accept additional wastewaters through tanker trucks. The first simulation study models the wastewater treatment facility to ensure its ability to handle the planned added capacity arriving through the pit, while the second study simulates various managerial strategies to handle the traffic, testing, and unload procedures of tanker trucks arriving at the facility. The simulation models were statistically validated and the outcomes of the study were implemented in reality. The wastewater treatment facility extension suggested by this study was implemented and launched in mid 2008 to accept residential wastewater tanker trucks. This has saved the environment over 6,000 m 3 daily from being dumped into the open unlined terrestrial landfills. Simulation proved to be an excellent tool in the facility planning effort, as it ensured smooth flow lines of tanker truck load discharge and the best utilization of facilities on site.

Impact of Corona virus pandemic on wastewater characteristics, treatment, and water reuse in a municipal plant

“…The plant receives the domestic wastewater from the Al-Jahra pumping station (JPS) through 2 pipelines, each serving a wide area of Kuwait. The Umm Al-Hayman (UAH) WWTP is located in the south of Kuwait near the coast, where the plant receives sewage from the central pumping station in the area and from a sewage pit that receives wastewater transported by trucks from rural areas (Aleisa et al, 2011). The plant was commissioned in 2001 with a design capacity of 27,000 m 3 /d.…”

The environmental life cycle assessment of different electricity options in Kuwait

“…Energy-intensive desalination plants (DPs) result in huge ecological and health impacts that need more comprehensive assessment (Al-Abdulghani, El-Sammak, & Sarawi, 2013;Aleisa, Al-Ahmad, & Taha, 2011). However, some power plants generate electricity, as well as water, and combine two or more thermodynamic cycles, resulting in improved overall efficiency, reducing fuel costs.…”

Leveraging life cycle assessment and simplex lattice design in optimizing fossil fuel blends for sustainable desalination

“…Approximately 81% of the total desalination production worldwide using MSF is generated in the GCC alone (Ghaffour et al 2014;, with an estimated total production capacity of 4.7 billion m 3 /yr (GCC Secretariat General 2015). However, when the urban air quality continued to show clear signs of elevated levels of air pollution (Abdulraheem 2010; Aleisa et al 2011;Darwish et al 2009), only then was the sustainability of MSF desalination in the GCC reconsidered. One distressing consequence is that Kuwait and other neighboring countries of the GCC are ranked among the top five per capita carbon dioxide emitters worldwide (The World Bank Institute 2014).…”
