Pectin And Alginate Extraction To Treat Liquid Cafo Manure, Clare Sunderman May 2021

Pectin And Alginate Extraction To Treat Liquid Cafo Manure, Clare Sunderman

Honors Projects

For this project, various extraction methods were used to extract pectin from Pastinaca Sativa and alginate from Macrocystis. These extractions were then dried and used in treating 250mL of manure along with a CaCl2 or FeCl3 coagulant. It was found that CaCl2 was not as effective as FeCl3 in coagulating manure. But the results obtained suggest that pectin and alginate obtained with a simpler extraction method is just as effective as the highly purified and refined pectin and alginate produced for the food industry, in the treatment of CAFO manure. The liquid portion of the …


Evaluation Of Cafo Dairy Manure Treatment To Reduce Nutrient Transport, Jenna Laib Apr 2018

Evaluation Of Cafo Dairy Manure Treatment To Reduce Nutrient Transport, Jenna Laib

Honors Projects

Excess amounts of phosphorus and nitrogen flowing into Lake Erie from agricultural fields in Northwest Ohio has led to several harmful algal blooms (HABs). One potential source of those nutrients is manure applied to fields for fertilizer. Manure from confined animal feeding operations (CAFOs) is 95-98% water with only ~3% solids and nutrients, thus physical transportation is expensive relative to the value of the agricultural nutrients. Furthermore, once manure nutrients are applied to agricultural fields, they are relatively easily mobilized to waterways by precipitation. More than 800 lab-scale tests have been used to optimize the treatment of CAFO manure with …


Conversion Of Cafo Manure Into A Slow-Release Fertilizer, Richard Allan Williams Iii May 2016

Conversion Of Cafo Manure Into A Slow-Release Fertilizer, Richard Allan Williams Iii

Honors Projects

Alginate polymer is known to form gel through the process of Ionotropic gelation. By use of extrusion and diffusion setting manure was encapsulated into gel beads. These beads were then tested to determine their potential for further testing as a manure treatment process. From the limited data in this preliminary study, it appears as though there is potential for further testing of alginate beads as a treatment process for manure. The treatment is potentially valuable because of the ease of filtration of the alginate beads, the low cost of transportation of the dehydrated beads, and because the limited data suggests …
