Production And Harvest Of Microalgae In Wastewater Raceways With Resource Recycling, Alexander Colin Roberts

Master's Theses

Microalgae can be grown on municipal wastewater media to both treat the wastewater and produce feedstock for algae biofuel production. However the reliability of treatment must be demonstrated, as well as high areal algae productivity on recycled wastewater media and efficient sedimentation harvesting. This processes was studied at pilot scale in the present research.

A pilot facility was operated with nine CO₂-supplemented raceway ponds, each with a 33-m² surface area and a 0.3-m depth, continuously from March 6, 2013 through September 24, 2014. The ponds were operated as three sets of triplicates with two sets continuously fed …

Nathan Cooper is a local boy with spinal muscular atrophy. He enjoys playing games and being active. One assistive device that Nathan uses is his Standing Dani, a motorized mobile stander. Nathan enjoys playing golf and kickball, and prior to this project he had no way of playing golf and no safe way of playing kickball. The purpose of this project was to design and build a golf attachment for Nathan’s Standing Dani that allows him to putt, and a kickball attachment that allows him to play kickball safely. First, the design team researched and defined the problem in terms …

Pepper Oak Farms, a company that grows their own olives for olive oil and has approximately 40,000 olive trees, is in need of an efficient way to monitor the soil and atmospheric conditions that are critical to the cultivation of their trees. The company at the moment only has two sensors and has to manually place the sensors at different locations to collect data on soil moisture and temperature. This is expensive, time consuming, and a lot of effort on the owner’s part to go out on the fields to collect this data. As a solution, the company would like …
