HW #2 (Download this page from Canvas & type your answers under each question). Due 10 pm, to Canvas, on Monday April 11 (pre-check due Thursday April 7 at 4pm). The Week 2 lecture notes are the basis for this HW, but I have uploaded a PDF from Zeta-Meter called “Everything you want to know about Coagulation & Flocculation” which is an excellent easy to read primer on the topic. For those of you who intend to continue in the water treatment field, I recommend you read the whole document.
process data to provide a specialized simple with online zeta potential analyzer for water treatment plants. Zeta potential analysis is completely automated and produces results in minutes whose maintenance is also minimal. The measurement of grab samples with temperature and sample flow sensors. Water treatment, petroleum emulsions, mineral flotation, nanoparticles, cement, and clay are a few of the applications. Laval Lab Inc.
