Never-Fail Math Approach – Jun 1 (8 – 10 am)
Using units (e.g., gal, ft, lb, mg/L) to set up math problems, to tell you whether to divide or multiply by a number, to give the correct answer, is a bit like playing dominoes. Learn the solution bridge most wastewater math problems will do themselves.
Solids and Organics (BOD, cBOD, NOD, and COD) – Jun 8 (8 – 10 am)
A lot of the terminology used in wastewater treatment can be confusing, especially for those just beginning their career. Before nutrient removal was a concern, wastewater treatment aimed at the removal of solids and organics.
Pumping – Jun 15 (8 – 10 am)
The need for pumps and pumping in wastewater treatment is universal. This lesson lays down pumping specifics in understandable terms and establishes a strategy for solving pumping problems.
Chemicals and Chemical Dosing – Jun 22 (8 – 10 am)
Chemicals are widely used in wastewater treatment. This lesson describes the more common chemicals used. In addition, a strategy for solving chemical dosing problems is presented.
Primary Clarifiers – Jun 29 (8 – 10 am)
For certification exams, many of us have memorized primary clarifier removal efficiencies typical in municipal wastewater practice. Have you ever wondered where those ranges came from? This lesson emphasizes the simplicity of primary clarification and what can and can’t be removed in primary clarifiers.
Ponds and Trickling Filters – Jul 6 (8 – 10 am)
Considered secondary processes, ponds and trickling filters find significant use in wastewater treatment. On this account, questions regarding them are frequently asked on certification exams. This lesson presents the basics of both and how loading problems—hydraulic and organic—should be approached.
Activated Sludge – Jul 13 (8 – 10 am)
Activated sludge is the most widely used wastewater treatment technology in the world, for good reason. It is reliable, versatile, and, when properly operated, economical. This lesson is an overview of the process, some of its modifications, and process control calculations.
Biological Nutrient (N&P) Removal – Jul 20 (8 – 10 am)
Oxidation of ammonia (nitrification), nitrogen removal (nitrification/denitrification), and biological phosphorus removal in the activated sludge process are presented. These processes are becoming more and more common in more and more geographical locations across the country.
Anaerobic Digestion – Jul 27 (8 – 10 am)
Most of the influent organics end up, in one form or another, being treated in the digester at municipal wastewater treatment plants. This lesson focuses on anaerobic sludge digestion which produces methane, a valuable byproduct.
Thickening and Dewatering – Aug 1 (8 – 10 am)
Thickening before and dewatering after sludge digestion is essential to the efficiency and expense of municipal wastewater treatment. Why that is so is the focus of this lesson, with an emphasis on a key performance metric, solids capture efficiency.
