Wastewater Calculations Workshop - June 2014

Refinery Water Engineering & Associates, Inc. (RWE) and Lamar University (LU) are proud to present the next edition of our Refinery & Petrochemical specific Wastewater Treatment Training resources. This upcoming event is all about the practical application of mathematical calculations for achieving quantifiable process control, as well as developing the correct metrics upon which to gauge historical performance. The latter goal allows for the next level of application of the Statistical Process Control (SPC) techniques advocated by Six Sigma. The classroom agenda will focus primarily on actually solving equations from real operating plant data. For plants that still use Trial & Error or Qualitative Process Control Techniques, there is no better or faster training resource available anywhere which can advance you to Quantified Mathematical Control and improved risk management of cause and effect.

When: Tuesday & Wednesday, June 3 & 4, 2014, 8am to 5pm.

Where: Lamar University, Beaumont, TX., Environmental Engineering Dept.

Workshop Size: 20 Attendees max. to insure individual attention.
