Join EFCN for this webinar series designed to help small wastewater system operators pass their certification exams. The series started with a 1-hour overview of study tips and test preparation techniques, and each subsequent 1-hour webinar focuses on a single topic typically found in Level 1 and Level 2 exams. Each session will include sample questions and a short Q and A period. This series can benefit new operators aiming for Level 1 and 2 certifications, as well as currently certified operators looking to pass higher-level tests.

This session focuses on the various types of solids in wastewater treatment and mechanical solids separation. We cover sludge thickening, introduce the topic of digestion, and discuss mechanical dewatering.
