An introduction to wastewater treatment process unlike any other out there. Whether you don’t know the first thing about what happens when you flush the toilet, or you’re an engineer or an operator with 20 years under your belt in waste water, there is certainly something in this video series for you. These videos take a holistic approach to the municipal wastewater treatment process, and first answer WHY we are treating what we treat, and only then going over HOW we treat wastewater, in a way that anyone can understand. The first video reviews the general contents of municipal waste water, what ill effects they would have if untreated, and therefore why we have to treat them. There is also an introduction to some basic measurements used in the wastewater treatment industry such as biological oxygen demand (BOD) and total suspended solids (TSS), including how and why we use them.
