Dosage vs. UV Batch Treatment Reactor Radius. Labeled as the green and red dotted lines are the Class A dosage standards set by NSF/ANSI 55. Since we will not be monitoring our UV output, we will need to conform to the 60 mJ/cm^2 standard.

Flowrate at varying reactor size and inlet flows. Since we want to have a system that outputs at least 0.5 gpm, and also optimizes size and portability, we will likely need to reduce reactor size, but increase the inlet flow rate to values shown.

Drawings, Schematics, Flow Charts, Simulations

Describe your design in enough detail for someone else to recreate it. Have you included assembly plans and user manuals? Your team may want to create separate nodes and directories within the Detailed Design Documents directory for CAD, schematics, or software

Purpose

Define instructions that will enable fabrication of the elements required to build and operate the entire system.

Instructions

  1. Instructions and EXAMPLE must be deleted before the Detailed Design Review AND Identify an owner for this document.
  2. This document will be inspected at all project reviews until the system is assembled and debugged.
  3. Define all geometries of interfaced subsystems
  4. Define detailed fabrication instructions for all unique parts.
  5. Call out all purchased parts
  6. Develop a software design that reflects operating flow charts and timing diagrams
  7. Adhere to all required design standards.
  8. Considering the purpose, the team should anticipate potential failure modes associated with construction and use of this document.

Input and Source

  1. Selected Concepts
  2. Feasibility Models
  3. System design and interface definitions

Output and Destination

  1. Complete hierarchy of design files from system level down to components
  2. Parts list
  3. Software design that specifies coding requirements
  4. Test plans, including expected performance vs. requirement and any applicable test standards (e.g., ASTM). The RIT library maintains an infoguide with links to standards databases, many of which provide industry-standard test procedures for a variety of components and systems.

Test Plans

Purpose

Demonstrate objectively the degree to which the Engineering Requirements are satisfied

Instructions

  1. Instructions and EXAMPLE must be deleted before the first Detailed Design Review AND Identify an owner for this document.
  2. Complete test plans specifying the data to be collected, instrumentation to be used, testing procedures and personnel who will conduct the tests.
  3. Plans should use data collected to define the accuracy of models generated during feasibility analysis.
  4. Tests demonstrate that you met engineering requirements, which map back to your customer requirements. You should include a snapshot of your test plans here, but maintain the continuity of using your team's master requirements and testing document.
  5. If your team's testing will involve human subjects, you must review the RIT Human Subjects Research Office "Protecting Human Subjects" page for details on securing approval for work with human subjects

Inputs and Source

  1. Engineering Requirements.
  2. Test standards (e.g., ASTM). The RIT library maintains an infoguide with links to standards databases, many of which provide industry-standard test procedures for a variety of components and systems.
  3. Feasibility Models.

Outputs and Destination

  1. Report that summarized the degree to which Eng Reqs are satisfied.
  2. Assessment of accuracy of feasibility models.

Design and Flowcharts

This section should continue to be updated from your systems level design documentation.
