Fall 2013 Contributions

This semester I was on the Turbulent Tube Flocculator team. We finalized the design of and fabricated a turbulent tube flocculator for testing flocculation under turbulent conditions - primarily the limited growth flocculation hypothesis. We fabricated PVC pipes fortified with metal bars to constrict the flocculator tubing at regular intervals. We constructed the flocculator and ran water through it to check for leaks. We have assembled some of the peripherals for flow control and data acquisition. Future work will include adding coagulation, effluent testing, and a draining system.

Spring 2014 Contributions

This semester I am on the Turbulent Tube Flocculator and Fluidized Bed Flocculator team. We have designed and constructed a settled water turbidity measurement apparatus (SWaT). We have written the control processes for the turbulent tube flocculator and hope to begin collecting data shortly. We are also designing a fluidized bed flocculator, in which an up-flow sand filter will act as the flocculator and SWaT will measure effluent trubidity.
