Replacing Conventional PFAS Water Treatment by GAC with Plasma Treatment to Improve Sustainability
Get PDFPer and poly-fluoroalkylated substances (PFAS) are carcinogenic compounds which make their way into water systems and are difficult to remove. Currently, PFAS is removed from drinking water at an industrial scale using granular activated carbon (GAC), a solid particulate which removes PFAS from water through adsorption. However, in recent years, a new method utilizing a plasma reactor to mineralize the PFAS has been designed and tested at small scales. This project aims to increase the scale of existing plasma reactor designs to treat the same volumes of water that traditional GAC plants are capable of treating. A specific well in New Castle County, Delaware was identified as the treatment site, and both processes were designed to treat 2.33 million gallons of water per day by reducing the PFAS concentration from 4,500 parts per trillion to the US EPA health advisory level of 70 parts per trillion. The GAC process was estimated to have a capital cost of 6.32 million each year. The plasma process was estimated to have a capital cost of 5.93 million each year. Based on a number of economic and environmental factors, this project found that the plasma system was a more effective and sustainable method for achieving the desired reduction in PFAS concentration
Production of PHAs from Microalgae
Get PDFBiodegradable polymers are becoming an attractive alternative to traditional petroleum-based polymers; namely, polyhydroxyalkanoates (PHAs) are naturally occurring biodegradable polyesters synthesized by various microorganisms and are one of the most promising sustainable plastic alternatives in the market. PHAs can be produced naturally by bacteria or algae without diverting crops and can biodegrade in landfills or even marine environments. This project produces PHAs from the microalgal species Scenedesmus, employing the use of flat plate photobioreactors for algae cultivation, gravity settling and centrifugation for harvesting and dewatering, microbubble extraction for cell lysis, and a separation train for the purification of PHA from lipids. The annual production capacity is 8,367 US tons of PHAs, 29,283 US tons of de-oiled biomass, and 4,183 US tons of lipid (triolein), with the primary goal of achieving a 15% internal rate of return (IRR). However, with a total capital investment of 19.3 million, this project fails to meet the desired economical outcome. The internal rate of return was 1.6% when using reasonable selling prices for the products but showed promise with a reduction of capital costs (e.g., reduction in algal photobioreactor costs) or an increase in the profit margins (e.g., increase in PHA selling price or reduction in utility usage)
Collation Model for LJS 195: [Medical miscellany]
Get PDFMedical compilation with a particular focus on the plague, but also including information on diseases of different parts of the body, urine, medicines, laxatives, water and wine, and the making of pigments for painting and inks for writing (f. 209r-215r).https://repository.upenn.edu/sims_models/1051/thumbnail.jp
Collation Model for Ms. Codex 65: La vita de Sancto Orso
Get PDFLife of Saint Ursus (or Orso), venerated in Santorso, near Venice in the province of Vicenza. The text was translated from Latin into Italian by Alberto Bischazza, archpriest of Rovigo (f. 1v). Also includes a prayer to Saint Ursus, in different ink in a different, possibly later hand, on the verso of the second flyleaf. Colophon in Latin (f. 14r) contains the notarial statement, without seal of signature, by the notary Ioannes Franciscus de Platea of Vicenza. The lack of a seal or date, added to the evidence of the corrected error of duplication in the explicit, indicates that this is a copy of a notarial copy.https://repository.upenn.edu/sims_models/1091/thumbnail.jp
