Reduction of Anaerobic Conditions in an Industrial Wastewater Pumping Station

Team Name – Team Abbott Labs
Sponsor – Abbott Labs (project under Non-Disclosure Agreement)
Faculty Advisor – Dr. Steve Safferman, PE

Abbott Nutrition’s facility in Sturgis, Michigan pretreats industrial wastewater before discharging to the local municipal treatment plant. The pumping station for Abbott’s pretreatment plant has experienced anaerobic conditions, which lead to hydrogen sulfide production, resulting in additional costs associated with pH neutralization. Team Abbott Labs evaluated multiple opportunities to improve the system, including adding baffles to the wet well, modifying or replacing the outlet pumps, and using a reverse osmosis system to treat boiler feedwater. The team recommended adding baffles and pump extensions and installing a reverse osmosis system. The payback periods of these designs are under two years.

Production of Methane via Carbon Dioxide

Team Name – Team Methanation
Sponsor – Consumers Energy (project under Non-Disclosure Agreement)
Faculty Advisor – Dr. Dana Kirk, PE

Due to the intermittent nature of renewable energy generation, a storage method for excess energy is necessary to balance supply and demand timing issues. Methanation provides a way to store excess energy as carbon-neutral gas. Methanation combines the use of waste carbon dioxide with hydrogen gas to form methane. Hydrogen gas is obtained from an alkaline electrolysis process and is powered with the energy generated from renewable energy. With the combination of these technologies, it is possible to store renewable energy.

Weyerhaeuser Thermal Oil Filtration

Team Name – Weyerhaeuser Thermal Oil Team
Sponsor – Weyerhaeuser (project under Non-Disclosure Agreement)
Faculty Advisor – Dr. Ajit Srivastava, PE

Weyerhaeuser is a timberland company located in Grayling, Michigan. They use thermal oil to heat resins for their oriented strand board (OSB). Repeated bearing failure in the thermal oil pumps has required Weyerhaeuser to incur significant costs for bearing replacements. This reoccurring issue has caused our team to evaluate Weyerhaeuser’s oil quality, leading to a proposed solution of a kidney loop filtration unit to be attached to the system’s reservoir.

Feasibility Study of Utilizing Hog Fuel for Onsite Heat Production

Team Name – The Woody Wonders
Sponsor – Weyerhaeuser (project under Non-Disclosure Agreement)
Faculty Advisor – Dr. Dawn Reinhold

Weyerhaeuser is a multinational lumber company that manufactures oriented strand board (OSB) at their mill in Grayling, Michigan. The mill produces a large amount of hog fuel, a waste stream comprised mostly of chipped wet bark, as a byproduct. The Woody Wonders have been tasked with determining a suitable outlet for the hog fuel that is economically viable and environmentally friendly. After evaluating several biomass combustion technologies and offsite mulching opportunities, the team chose to implement an on-site fluidized bed boiler that burns the hog fuel for heating Weyerhaeuser’s thermal oil. This boiler was evaluated for feasibility.

Portable Electrocoagulation Unit for Wastewater Treatment on Remote Army Bases

Team Name – Team Clean Drinking
Sponsor – Department of Defense
Faculty Advisor – Dr. Wei Liao, PE

The Department of Defense (DOD) wants to employ a small-scale wastewater treatment system on remote U.S. Army bases. Team Clean Drinking designed an electrocoagulation unit, which is the initial step in wastewater treatment. This unit proceeds the ultrafiltration advanced membranes treatment to convert wastewater into water that meets the EPA treated wastewater discharging standard. The system needs to be portable within a skid and serve up to 150 soldiers. The system was designed to be set up quickly and operate in a wide range of climates with minimal labor.

Lifecycle Assessment of PET with Multiple End-of-Life Scenarios for BIGGBY COFFEE

Team Name – Just Brew It
Sponsor – BIGGBY® COFFEE (project under Non-Disclosure Agreement)
Faculty Advisor – Dr. Chris Saffron

The team worked with BIGGBY® COFFEE, a coffee company headquartered East Lansing, Michigan with franchises across the Midwest. Team Just Brew It worked to determine the ecological footprint of BIGGBY®’s cold cups composed of the plastic polyethylene terephthalate (PET), which will aid the company’s sustainability efforts. A lifecycle assessment was performed on four different end-of-life alternatives, including landfilling, physical recycling, chemical recycling, and combustion, to quantify the company’s ecological impact and determine the optimal disposal method.

Cleaning Koppert’s Bee Bottles to Recycling Requirements

Team Name – Bee-duce, Bee-use, Bee-cycle
Sponsor – Koppert Biological Systems, Inc.
Faculty Advisors – Dr. Dan Guyer & Mr. Phil Hill

Koppert, located in Howell, Michigan, raises bumblebees for commercial-scale pollination and is looking to reduce their environmental footprint. Koppert feeds their bees a sugar solution from high density polyethylene (HDPE) bottles. Due to the sticky nature of the sugar and bee residues, the bottles are not meeting the requirements of the local recycler. Through research and experimentation, a pressurized water system was developed. Based on experimentation, the process cleans 97% of the bottles with a single pass. After installation and final adjustments, 100% of Koppert’s bottles will be clean enough for recycling.

Improvement of a Potato Storage Ventilation System Using Modified Air Cup Design

Team Name – Team Techmark
Sponsor – Techmark, Inc.
Faculty Advisor – Dr. Wei Liao, PE

Techmark, Inc. is a multi-industry agricultural corporation based in Lansing, Michigan that specializes in root crop storage. Techmark, Inc. designs conditioned air handling systems at a specified velocity through a piled potato storage facility. Improper ventilation contributes to pressure bruising causing product (food waste) and revenue loss. The hypothetical cause is shearing forces at sharp-edged orifices at air cup inlets. The team performed a computational fluid dynamics (CFD) analysis of a single air duct with 28 air cups using 4 design alternatives. Design alternatives to the air cup inlet that increased air velocity and prevented pressure bruising were analyzed.
