For this semester, the team aspires to build on the research of the Summer 2018 team and determine whether a flow recycle system will increase floc blanket uniformity. They will also explore the effects of varied angles of entry and pipe thickness on the flow recycle system
Fluoride contamination of groundwater is a major, well-known health concern, that still does not have any highly effective or sustainable technologies to remedy it. The World Health Organization suggests the Nalgonda method, but this technique has several major flaws including a treatment efficiency that is limited to only 70 percent, and a large dose of aluminum sulfate, which causes sludge disposal problems. Instead, we use Polyaluminum Chloride (PACl) as a coagulant to which the fluoride can both adsorb to and coprecipitate with. The goals of the Fluoride Team is to design and create the optimal system for adsorbing and coprecipitating out fluoride from groundwater.
Investigate the effluent HA concentrations as coagulant dosages increase for certain HA influent concentration using spectrophotometer. Design experiments to compare HA effluent concentration trends for different HA influent concentations.
We aim to design a system that removes excess dissolved gas from influent water prior to entry into an AguaClara water treatment plant.
What is a UASB: a form of anaerobic digester that is used for wastewater treatment.
Wastewater enters the reactor from the bottom, and flows upward. A settled sludge blanket filters and treats the wastewater as the wastewater flows through it.
This semester, the team will be working on running tests with a lab-scale UASB reactor to determine optimal geometry of components. Additionally, UASB Research will be running dye-tests with synthetic sludge to study flow patterns of water moving through the reactor, and identify fail conditions.
The Fabrication team will be fabricating a full-sized prototype UASB reactor that will be commissioned for testing at the Ithaca Area Wastewater Treatment Facility. They will also be creating CAD drawings of the UASB reactor using Onshape to make the designs available to all on an open-source platform.
The team's goal this semester is to determine if ideas about using strings as media for trickling filter based design are a feasible component of a future AguaClara wastewater plant.
