APSC 150: Engineering Case Studies/Case 1 Biological Engineering Assignment #1-Conceptual Process Design Question 1 Acme produces 70,000 m 3 /day of wastewater (about the same volume as produced by the City of North Vancouver). The wastewater contains only one contaminant, namely 300 mg/L of methanol. The authorities have told Acme that they have to remove 90% of the methanol before the wastewater can be released into the environment. a) What would be the environmental impacts associated with the wastewater being produced by Acme? If possible, try to quantify the environmental concerns that you identify. b) Based on your assessment of the environmental concerns, produce (by brainstorming in your group) a number of ideas as to how the wastewater could be treated to achieve the required goal. c) Develop a rating system for your list of possible solutions and score each solution based on each criterion from 1 (poor, bad) to 5 (good). Methanol Removal Method Evaluation Criteria i ) ii) iii) i v ) v ) v i ) vii) Total score d) After identifying your best (highest scoring) technology from part “c”, sketch out a conceptual flowsheet for your treatment process. While doing so, identify things that you would need to know (knowledge gaps) to move to a more detailed design that someone could use to build your process.

APSC 150: Engineering Case Studies Assignment #2-Stoichiometry Question 2-1 Chemical oxygen demand is the oxygen required to completely oxidize a compound under rigorous chemical oxidation conditions. For compounds that can be completely oxidized, the COD can be estimated by writing a balanced chemical equation for complete oxidation. a) If a bacteria can be represented by the formula C 5 H 7 O 2 N, what is the COD equivalent of 1 mg/L of biomass (assume N ends up as NH 3 )? b) Potassium hydrogen phthalate (KHP) is a chemical compound used as a standard for the COD assay. The formula for KHP is: C 8 H 5 0 4 K. Determine the concentration of KHP required to give a solution with a COD of 500 mg/L. Assume that the potassium ends up as KHCO
