Cal Poly On-Site Water Treatment Project Proposal, Tanner Wingo
Cal Poly On-Site Water Treatment Project Proposal, Tanner Wingo
Biomedical Engineering
This report is based off of a competition hosted by the Environmental Protection Agency (EPA): the 2015 Campus RainWorks Challenge. Student teams were encouraged to design an infrastructure that could manage storm water, benefit campus life, and promote sustainability. The report summarizes the engineering aspects that support the competition submittal. The design is to treat campus wastewater on-site and to a suitable level for either reuse or discharge into Brizzolara Creek.
Treatment Of Dissolved Metals For Direct Potable Reuse, Cesar Alberto Alvarez
Treatment Of Dissolved Metals For Direct Potable Reuse, Cesar Alberto Alvarez
Open Access Theses & Dissertations
In the process of direct potable reuse (DPR), the bulk of the removal of dissolved metals removal is accomplished by reverse osmosis. This treatment is especially important in wastewater containing contaminants from industrial processes. The goal of this research was to evaluate the performance of DPR with respect to the removal of salinity and dissolved metals to meet drinking standards. Samples were collected from the El Paso Water Utilities Advanced Water Purification pilot system throughout various points in the treatment process. The samples were analyzed for their concentration of ions with Ion Chromatography (IC) and dissolved metals using an Inductively …
Water Quality Evaluation Of Tire Derived Aggregate, Richela K. Maeda
Water Quality Evaluation Of Tire Derived Aggregate, Richela K. Maeda
Projects
The primary objective of this study is to investigate the rate that potential water quality contaminants leach from tire-derived aggregate (TDA) as a function of time. A laboratory and field experiment is conducted to provide insight into both controlled and field settings. The laboratory portion of this study also provides a basis for evaluating the effect that alternating periods of wet and dry weather have on the potential water quality impacts of the leachate as compared to the worst-case operating condition, when TDA is constantly submerged (i.e., when placed below the permanent groundwater table). The field experiment is used to …
Pilot-Scale Study Of Low-Tech Methods Of Sustainable Class A Biosolids Production: A Trial Run, Rebecca L. Green
Pilot-Scale Study Of Low-Tech Methods Of Sustainable Class A Biosolids Production: A Trial Run, Rebecca L. Green
Dissertations, Master's Theses and Master's Reports
Water resource recovery facilities can improve sustainability by producing Class A biosolids. However, many conventional methods for achieving Class A biosolids are expensive, with high maintenance and energy costs. However, low-cost, low-tech (LCLT) treatment methods are also available. The overall goal of the larger project of which this study was a part is to develop a rational and universal approach for design of LCLT processes. To achieve this goal, pilot-scale studies of LCLT processes will be performed. The goal of this portion of the project was to perform a trial run pilot-scale study. During the trial run, the pilot-scale biosolids …
