This webinar will provide a comprehensive overview of the Leak Registry Requirements due July 1, 2026, and share best practices for tracking and compiling leak information. Participants will gain practical insights into compliance strategies, data management techniques, and tools to streamline reporting processes.

Unlike other industry-wide exams the Grade 5 Water Treatment is an oral exam which requires a different preparation approach.  Unlike a traditional exam that requires hours of completing practice problems, being prepared for the T5 exam more closely resembles preparing for a job interview.  This webinar will focus on how to prepare for the oral exam.  The webinar will include an overview of key study areas, techniques for preparing for the exam and strategies for answering questions during the oral exam.

Module 1: Understanding Water Hardness

• Define total, carbonate, and non-carbonate hardness and their impact on water systems.

• Explain how hardness causes scaling, staining, and soap precipitation in domestic and industrial systems.

Module 2: Lime Softening Chemistry and Principles

• Describe the chemical reactions that occur during lime softening, including precipitation of calcium carbonate and magnesium hydroxide.

• Identify key pH thresholds for calcium and magnesium removal and explain the role of recarbonation.

Module 3: Lime Types and Slaking Process

• Distinguish between quicklime and hydrated lime, and explain the lime slaking process including safety and equipment concerns.

• Identify challenges in lime feed systems such as dust control and caking.

Module 4: Softening Process Variants

• Compare partial lime, excess lime, lime-soda ash, caustic soda, and combined lime/caustic soda processes.

• Describe when to apply each process based on source water quality and operational goals.

Module 5: Process Flow and pH Stabilization

• Outline single-stage, double-stage, and split treatment lime softening designs.

• Explain the role of carbon dioxide in recarbonation and the need for pH adjustment post-softening.

Module 6: Ion Exchange Softening

• Explain how ion exchange (IX) works using sodium zeolite resins to replace calcium and magnesium with sodium ions.

• Describe the regeneration process using brine solution and identify the stages of IX operation (service, backwash, brine, rinse).

Module 7: Ion Exchange System Design

• Calculate resin capacity in grains per cubic foot and determine flow rates and resin bed requirements.

• Identify applications of IX systems including blending, fluoride saturator supply, and nitrate removal.

Module 8: Membrane and Brine Management

• Compare membrane softening with IX and lime softening in terms of pressure requirements and waste stream.

• Explain brine management strategies, environmental concerns, and regional solutions like the Santa Ana River brine line.
