Diffusion Of A Salt In An Aqueous Media, Aldaly Pineda Hernandez
Diffusion Of A Salt In An Aqueous Media, Aldaly Pineda Hernandez
Chemical Engineering Undergraduate Honors Theses
Diffusion is defined as the net transfer of a molecule from a high concentration region to a low concentration region. The concept of diffusion is used in a very important process called "desalination." Desalination is a separation process used to reduce the salt content dissolved in brackish water to make it suitable for human consumption, irrigation, and industrial use.
In desalination plants, it is important to monitor the constantly changing salt content of water, partly due to the diffusive effect. The main purpose of this experiment was to study the diffusion of NaCl in water at two NaCl concentrations. The …
Removal Of Fluoride From Mine Water Via Adsorption For Land-Applied Soil Amendment, Michelle Dopp, Kevin Le, Ethan Phan, Mary Johnson, Jacqueline Payne, Adrian Damian, Courtney Golman
Removal Of Fluoride From Mine Water Via Adsorption For Land-Applied Soil Amendment, Michelle Dopp, Kevin Le, Ethan Phan, Mary Johnson, Jacqueline Payne, Adrian Damian, Courtney Golman
Chemical Engineering Undergraduate Honors Theses
The Moo Pig Sooie’s researched, designed, and economically analyzed a full-scale adsorption column system to be applied in mining processes that leave high amounts of fluoride in their effluent. This system was designed to remove fluoride from water saturated with calcium sulfate, as calcium sulfate is present in high amounts in certain mining processes. Currently, high density sludge (HDS) is commonly employed to reduce fluoride concentrations, but due to solubility limits the sludge treatment cannot lower fluoride below 10 mg/L (ppm). The current enforceable EPA standard for discharged water is at 4 mg/L (ppm), although mining companies anticipate that this …
Removal Of Carbamazepine From Drinking Water, Zachary Wiese
Removal Of Carbamazepine From Drinking Water, Zachary Wiese
Chemical Engineering Undergraduate Honors Theses
Due to the increasing prevalence of prescription medication over the past few
decades, pharmaceuticals have accumulated in various water sources. This has become a
public health concern because many pharmaceuticals have limited research on the effects
of chronic low-level exposure. According to the World’s Health Organization (WHO),
traces of pharmaceuticals products have been reported in different water sources such as
surface waters, wastewater, groundwater, and drinking water.[1] One pharmaceutical of
interest that has been detected in water sources is carbamazepine. Carbamazepine is a
common pharmaceutical prescribed for the treatment of seizure disorders, neuropathic
pain, and various psychological disorders. It’s mechanism …
