    Water resource management under short term system perturbations such as storms and longer-term systemic changes caused by climate change such as droughts is a challenge when multiple agencies are involved. To address this challenge this research focuses on water management under changing climate conditions and population growth through understanding the agency water jurisdictions, management strategies, and modes of operation in Las Vegas Valley. A framework for integrated management through sharing data and models is presented that combines drinking water supply, flood control, and waste water treatment. This framework can be adopted to improve coordination among different water management agencies

    Denpasar General Hospital of Wangaya is a B type non-training hospital. This hospital has Water Waste Treatment (WWT) to procees liquid waste using an aeration system. Waste water parameters at outlet were above the standard. The aim of this study was to identify the influencing factors to waste water management at Denpasar General Hospital of Wangaya. This was an observational study with cross sectional approach. Sample was 30 workers who involved in hospital waste water management. Data were taken by using a questionnaire, direct interview and examining BOD, COD, TSS, free NH3 and coliform parameters at the outlet of WWT. It was found that the workers who had sanitary background only 10% and all the workers never had specific training about hospital waste water management. Knowledge about hospital waste water management still low and as well as motivation of the workers. There was standard operational procedure for hospital waste water management and it was revised in 2001. It is suggested to provide trainings on hospital waste water management, doing periodical monitoring on WWT management, and doing field work supervision and evaluation. Keywords: hospital, waste water, managemen

    This article is about the discussions held at the 16th session of the Commission on Sustainable Development and recognizes that Integrated Water Resources Management (IWRM) was the framework for the entire water sector and an essential tool for effectively managing water resources and water-related issues. This article highlights certain connections between water and the following thematic areas: 1) sustainable consumption and production, 2) mining, 3) chemicals, 4) waste management and 5) transport

    G-189A analytical simulation of the integrated waste management-water system using radioisotopes for thermal energy

    Get PDF
    An analytical simulation of the RITE-Integrated Waste Management and Water Recovery System using radioisotopes for thermal energy was prepared for the NASA-Manned Space Flight Center (MSFC). The RITE system is the most advanced concept water-waste management system currently under development and has undergone extended duration testing. It has the capability of disposing of nearly all spacecraft wastes including feces and trash and of recovering water from usual waste water sources: urine, condensate, wash water, etc. All of the process heat normally used in the system is produced from low penalty radioisotope heat sources. The analytical simulation was developed with the G189A computer program. The objective of the simulation was to obtain an analytical simulation which can be used to (1) evaluate the current RITE system steady state and transient performance during normal operating conditions, and also during off normal operating conditions including failure modes; and (2) evaluate the effects of variations in component design parameters and vehicle interface parameters on system performance

    Importance of biological systems in industrial waste treatment potential application to the space station

    Get PDF
    In addition to having applications for waste management issues on planet Earth, microbial systems have application in reducing waste volumes aboard spacecraft. A candidate for such an application is the space station. Many of the planned experiments generate aqueous waste. To recycle air and water the contaminants from previous experiments must be removed before the air and water can be used for other experiments. This can be achieved using microorganisms in a bioreactor. Potential bioreactors (inorganics, organics, and etchants) are discussed. Current technologies that may be applied to waste treatment are described. Examples of how biological systems may be used in treating waste on the space station
