Title: Filter Surveillance Workshop
Description: This course will provide an overview of proven filter monitoring techniques essential to effective filter maintenance and operational optimization. Blending unique, interactive classroom segments with topic-focused, small-group breakout sessions and an equipment exhibit, the entire workshop program incorporates a learning-by-seeing-and-doing focus utilizing an active filtration plant. Practical presentations by operations and engineering professionals experienced in filter surveillance, operational, and maintenance techniques will guide participants through the learning experience. Space is limited on a first come, first serve basis.
Who Should Attend: The Filter Surveillance Workshop is an instructional program designed for both filtration plant operations and management personnel. Others seeking an overview of and general background in filter surveillance will also find this workshop of interest.
Pre-requisites: None
CEUs: 0.6
Learning Objectives/Outcomes: In this interactive workshop, participants will have an opportunity to Examine the rationale for filter maintenance; Examine Specific Filter Components (Filter Media, Underdrain Types, Filter Troughs and Weirs); Examine various filter surveillance techniques in detail via video media; Examine, evaluate and compare “host plant” filter characteristics with their own plant; and Observe and (when applicable) perform specific “hands-on” filter surveillance techniques (Visual observation of drained filter; Backwash turbidity/Floc Retention Analysis; Media (Sieve) Analysis; and Backwash Bed Expansion Test).Upon completion of the course you will be able to: Describe the benefits of filter surveillance; Describe the importance of stepwise evaluation of the entire filtration process; Identify the steps in filtration process evaluation; Identify the components of various types of filters; Describe how various types of filters operate; Be able to identify various types of media, under drains, troughs and weirs; Describe of the current filter surveillance tests; Describe how to implement and interpret each of the current filter surveillance tests; Describe the filtration and treatment process sequence in the host filtration plant; Describe the filter configuration in use in the host filtration plant; Describe how specific filtration processes operate in the host filtration plant and be able to relate and compare both configuration and processes to the participant’s plant; Describe the importance and proper application of filter surveillance techniques in plant optimization; Identify the steps in gravel probe sampling; Demonstrate the ability to analyze gravel probe corings as a filter surveillance tool; Describe how to conduct a backwash turbidity analysis and know the key steps in the procedure; Describe how to conduct a floc retention analysis and know the key steps in the procedure; Describe how to conduct a sand and coal (anthracite or granular activated carbon (GAC)) media sieve analysis and identify the key steps in the procedure; Describe how a backwash bed expansion test is utilized to analyze filter performance and know the steps required to conduct the test; Observe a filter backwash bed expansion test and recognize proper filter backwash function; identify problems in filter backwash function; Explain and demonstrate how a backwash bed expansion tool is utilized; Demonstrate the steps in backwash bed expansion; Demonstrate how the media is captured in the backwash bed expansion tool; and Analyze the results utilizing the backwash bed expansion tool.
Learning Outcome/Assessment Method: In addition to the course’s breakout group-based interactive learning stations and reports to the overall group, a multiple choice written self-assessment of learning outcomes will be administered following completion of the morning and afternoon sessions of the course. The written assessment will be comprised of straight forward multiple choice questions covering the core content of each instructional segment (presentation) and general course information for a total of ten questions. Each multiple choice question will examine your knowledge and understanding with regard to key concepts and information presented in a given segment and the overall course. There will be no trick questions. Following the completion of each assessment, a group review of the assessment will be conducted by the course facilitators and the NEWWA Education Staff proctor. Participants will “self correct” their assessments during this review and indicate their score on the top of their answer sheets. Participants must achieve a score of 7 out of 10 correct for a “passing grade”. Answer sheets will be submitted to/reviewed by NEWWA Education Staff proctor during the course sign-out process. Any participant who does not achieve the required passing score will meet with the NEWWA Education Staff proctor for an oral review/debrief following completion of the course. This will provide learners with an opportunity to re-examine assessment questions and answers, clarify information, and develop insight into their responses. It will also provide an opportunity to access additional learning support if needed.
