Mother Road Brewing Company Wastewater Pre-Treatment
Project Scope
The following list of tasks will be completed by Still Water Treatment Engineering throughout the project. This list of tasks does not include the project exclusions.
Task 1.1: Research - The goal of conducting research is to identify all pertinent information on project technical issues.
Task 1.2: Identify Existing MRBC Process - The MRBC brewery process will be completely documented. Equipment, process lines, pumps/controllers will be identified with size and capacity information. A complete process block diagram will be created showing all pertinent information. A to-scale diagram of the facility layout will also be created.
Task 1.3: Obtain COC Data - The team will gather weekly data produced by the MRBC laboratory for COC concentration along with flowrates in order to understand which levels are in exceedance and which contaminant reductions are a priority. The collected data will be from January 2021 through December 2022.
Task 2.1: Creation of a Lab Binder - The team will be preparing a lab binder detailing the test methods, reasons for testing, and health and safety parameters in order to access the NAU laboratories.
Task 2.2: Obtain Samples - The team will develop a sampling plan and collaborate with MRBC to obtain samples that can be used to conduct laboratory tests in Task 2.3.
Task 2.3: Conduct Testing and Analysis - Testing shall be conducted for the concentrations of BOD, TKN, TSS, and VSS, and phosphates. Among these tests, TKN and BOD analysis shall be critically evaluated to better summarize overall efficiency since these values are currently in exceedance. These tests shall be performed at NAU’s Environmental Engineering Laboratory. The VSS test will inform the team of preexisting biological feed within the sample and will determine the need to add biological feed to the treatment process should there be a lack of organic content while phosphate concentration will determine if a biological treatment solution is feasible.
Task 3.1: Identify Technologies - Using background knowledge from Task 1.1, an understanding of which COCs must be reduced and to what extent, the team will identify pretreatment methods that will best serve the project’s purpose.
Task 3.2: Create Screening Decision Matrix for Initial Alternatives -
A screening decision matrix with suitable criteria and weighting of each criterion will be developed to evaluate alternatives in Task 3.3.
Task 3.3: Select Alternatives - Technical options identified in Task 3.1 will be combined into five alternatives; these alternatives will be scored against the screening decision matrix to identify three alternatives to be further analyzed in Task 3.6.
Task 3.4: Create Digital Models - This task consists of creating functional mathematical models in Excel or other software to determine the performance of the three alternatives.
Task 3.5: Conduct Model Analysis - This task involves running the models designed above so that data can be collected.
Task 3.6: Create Final Decision Matrix for Selected Alternatives - A final decision matrix with suitable criteria and weighting will be developed to evaluate the three alternatives from Task 3.3.
Task 3.7: Analyze Results and Select a Preferred Alternative - The alternatives will be scored against the final decision matrix from Task 3.6 to select the preferred alternative.
Task 4.1: Operational Parameters and Sizing - The size of the treatment unit will be formulated with respect to variables such as flow rates, hydraulic retention time (HRT) and the organic loading rate. Proportions and treatment efficiency will also be considered to determine what the overall size of the unit will be. This shall produce the final dimensions of each constituent of the treatment design.
Task 4.2: Material Selection - Selection of materials of construction shall be based on their compatibility with the wastewater streams, availability, and cost.
Task 4.3: Final Design Drawings - A digital draft of the final pretreatment unit design will be created with detailed specifications including sizing and other pertinent variables. Additionally, an operation and maintenance manual will be developed.
Task 6.1: 30% Deliverables - The 30% deliverable consists of a report and presentation. The 30% milestone will be the completion of Task 1.0, Task 2.0, and Tasks 3.1-Task 3.3 and will be submitted on February 21, 2023.
Task 6.2: 60% Deliverables - The 60% deliverable consists of a report and presentation. The 60% milestone will be the completion of Tasks 3.4-3.7 and will be submitted on March 21, 2023.
Task 6.3: 90% Deliverables - The 90% deliverable consists of a report and website. The 90% milestone will be the completion of Task 4.0 and 5.0. This will be due April 21, 2023.
Task 6.4: Final Project Deliverables - The final deliverable consists of the final report, a presentation, website, and the Operations and Maintenance (O&M) Manual. These will be submitted on May 8, 2023.
Task 7.1: Meetings - Meetings will be scheduled and attended throughout the project to ensure project goals are met and deliverables are completed on time. Includes client, technical advisor, grading instructor, and team meetings.
Task 7.2: Schedule Management - Maintenance of the project’s schedule is paramount for the project’s success. Throughout the project, the team will track scope and schedule progress.
Task 7.3: Resource Management - Over the course of the project, the team will be tracking all resources required for the project such as staff time and supplies used.
