What do you know about the various activated sludge configurations currently used, available, and evolving for activated sludge, BNR, and ENR processes? The objective of this class is to give activated sludge plant operators a more in-depth understanding of the activated sludge process. With this understanding, effluent quality variability and process energy usage can be reduced. Topics to be presented include: wastewater characterization, biological N & P removal, the importance of sludge quality, measuring and controlling sludge quality, WAS flow control, RAS flow optimization, secondary clarifier performance diagnostic testing. Specifically, types of aeration diffusers (mechanical, fine bubble, and membranes) and blowers (positive, multistage, single stage, and high speed) will be addressed. The influence of MCRT and MLSS will also be addressed as to the efficiency, ease (or difficulty) and cost of aeration. Finally, helpful operating hints will be provided based on experiences from operating facilities.
This course is designed to train water or wastewater operators in the principles of chlorination. Subjects include review of various disinfection technologies and discussion of the main types of chlorine application systems.
This course is designed for anyone dealing with permit required confined spaces including safety professionals, emergency personnel, firefighters, sanitary engineers, public works personnel, chemical workers, maintenance staff and waste water treatment employees.
This course teaches participants the regulations, procedures, and practices to work safely in spaces defined by OSHA as permit required confined spaces. This course is designed to teach the worker to recognize the spaces and their hazards, recognize the health effects of exposure, testing procedures for atmospheric monitoring, proper selection and use of PPE, and the duties and responsibilities for the confined space entrants, attendants and supervisors. Training meets OSHA29 CFR1910.146 standards. Topics include:
Recognizing Permit Space Hazards
Confined Space Entry/Permits
Protective Equipment for Entry
Duties of Entrant/Attendants/Supervisors
Hands on Training/Equipment Use. Senior adult and disabled retiree course fee waivers apply. Transcript available.
Appropriate operations of the pumps and their maintenance are critical to keeping
water and wastewater systems up and running daily. This training will give the
participant an introduction to the theory and operation of the various pumps used in water and wastewater systems. In addition to an overview of basic pump hydraulics and pumping systems, there will be discussions on centrifugal pump
operation, components, maintenance and troubleshooting. Transcript available.
"Lockout/Tagout (LOTO)" refers to specific practices and procedures to safeguard employees from the unexpected energization or startup of machinery and equipment, or the release of hazardous energy during service or maintenance activities. This requires that a designated individual turns off and disconnects the machinery or equipment from its energy source(s) before performing service or maintenance, and that the authorized employee(s) either lock or tag the energy-isolating device(s) to prevent the release of hazardous energy and take steps to verify that the energy has been isolated effectively. This course addresses practices and procedures necessary to disable machinery and prevent the release of potentially hazardous energy while maintenance or servicing activities are performed. Senior adult and disabled retiree course fee waivers apply. Transcript available.

Preparation for Refrigerant Recovery Certification
Learn about the regulations, procedures and equipment that apply to refrigerant recovery, reclaiming and recycling in accordance with the Environmental Protection Agency (EPA) certification standards. Senior adult and disabled retiree course fee waivers apply. Transcript available.
Operators and superintendents must recognize many of the common Standard Practices used at water and wastewater systems today can lead to a potential catastrophic issue at their facilities. This course looks at some of these issues, where if not addressed, can ultimately lead to events that potentially cause bodily harm or even kill operators and customers if not effectively addressed. First, we will look at the results of lack of verification of even the very basic chemicals delivered to our facilities, document case histories where events have occurred, and show system personnel how simple and easy a verification program is to establish. Next, we will address operational issues such as the laboratory result where the Pink-Red color that develops in the DPD Chlorine test, but is not chlorine; and what operations personnel can to do to mitigate these issues. Additionally, learn why the Infrastructure Age requires extra vigilance to prevent system contamination. Even with backflow prevention, the fact remains that a garden hose is still the number one potential contamination source for water systems. We will discuss why water stagnation and biofilm formation can lead to bacterial contamination and how operations can minimize these issues with simple low-cost steps.
