Wastewater Lab & DMRQA - Hybrid

Description:

This session discusses most laboratory tests required to be completed at a wastewater treatment 
plant. Methods for pH, ammonia, total phosphorus, total nitrogen, total suspended solids, total solids, 
volatile solids, E. coli, CBOD, and CBOD seeding. Lab safety, sampling procedures, storage, and 
preservation requirements. Documentation and troubleshooting of lab issues. Laboratory 
calculations. Review of DMRQA testing requirements, equipment needed to efficiently make up the 
samples, methods for testing a sample of unknown strength, CBOD strategy, some of the common causes 
of errors, and reporting.

Learning Outcomes:

By the end of this session, participants will be able to:

1. Describe methods for testing pH, ammonia, phosphorus, nitrogen, solids, E. coli, and CBOD, including CBOD seeding.
2. Apply laboratory safety practices and proper sample collection, storage, and preservation procedures.
3. Perform laboratory calculations and document sample preparation, testing, and results.
4. Identify common laboratory errors and troubleshoot equipment, procedures, and inconsistent results.
5. Prepare and test DMRQA samples of unknown strength using appropriate equipment, dilutions, and CBOD strategies.
6. Explain DMRQA testing and reporting requirements.
