Treatment of shale gas wastewater in the Marcellus : a comparative analysisYisa, Junaid Ololade 18 November 2014 (has links)
This analysis focused primarily on three main treatment methods which were re-use, recycle, and disposal wells. The re-use treatment option is when wastewater is mixed with source water in order to meet fracturing water requirements. With this option, the hope is that the wastewater for re-use will require little or no treatment at all. The second treatment option is the recycle option. This option provides high quality water for re-use or discharge to the environment using a recycling technology. The credibility of this option is heavily dependent on its ability to recycle almost all of the wastewater with little or none left for disposal or treatment. The third option is well disposal. This entails disposing all of the wastewater into a deep formation. The software used for building the model is called @Risk. The model’s costs were estimates from recent research to capture the risks and uncertainties associated with wastewater disposal. The model revealed that re-use option remains the most cost effective treatment method to reduce overall water management cost in the Marcellus. The re-use option is most viable when a hydraulic fracturing schedule is continuous (no significant storage requirement) and infrastructure is available to transport wastewater from one fracturing operation to the other. The recycle option is the second most viable disposal option. This option is most effective when the hydraulic fracturing schedule is staggered in both time and distance because distilled water from recycling facilities can be easily discharged into the environment or stored. The most unfavorable option for wastewater management at the Marcellus is the well disposal option due to the high cost of trucking wastewater to disposal wells in neighboring states or counties. It also requires the highest usage of fresh water. A well disposal option can be favorable at the onset of a hydraulic fracturing schedule when there are low levels of infrastructure, hydraulic fracturing programs are not continuous or localized in proximity, and the volume of wastewater does not exceed the capacity for injection. In this case, disposal wells can be more favorable than recycle or re-use if they are in close proximity to drilling sites. / text

Decision factors that influenced hospital foodservice directors to implement a waste management programBasler, Joann 01 May 1996 (has links)
Economic, environmental, social and political influences made the management of
solid waste or garbage an important issue for all foodservice directors, including those
in health care facilities. The study objectives were to: (1) identify what components
of integrated waste management programs were being used in hospital foodservice
facilities in Oregon, Washington and Idaho, (2) identify decision making factors for
implementing or not implementing components of a solid waste management (SWM)
program, (3) determine which of the decision factors were perceived to be the greatest
barriers to implementing a SWM program, and (4) determine if demographic
characteristics influenced the foodservice director's decision regarding SWM. A
survey was sent to all (N=199) hospital foodservice directors in the three state region.
Of the 164 returned surveys, 75% of the directors reported they had recycling
programs, 51% participated in source reduction and 6% used incineration.
Foodservice labor, space to store recyclables, corporate support, monetary return and
the director's personal feelings were identified as decision factors (p= < .05) Space to
store recyclables and foodservice labor were considered the greatest barriers to recycling. Larger hospitals recycled more often and contracted foodservice operations
participated more in source reduction. Information on the decision factors that were
identified, can provide guidance to other directors as to the critical factors that should
be considered when attempting to implement a successful SWM program and solutions
could be developed to overcome or lessen the effects of the barriers. / Graduation date: 1996
