Tackling Industrial Wastewater Treatment Challenges
Sunday, October 19, 8:30 am – 4:30 pm
1 day, 0.6 CEUs
This workshop will provide a good understanding of industrial manufacturing processes and treatment of the resulting wastewater. The workshop will consist of six presentations from distinguished and well known presenters, followed by breakout sessions.
The first presentation will discuss relationship of various industrial manufacturing processes and resulting wastewater. It will elaborate pollution prevention and waste minimization approaches that can be used to decrease the need for end-of pipe treatment. Additionally, this presentation will discuss advantages of at-source wastewater treatment and strategies to facilitate this in existing manufacturing facilities. The presentation will also discuss wastewater treatment unit operations that will be needed for certain manufacturing processes.
The second presentation will discuss the characterization of wastewater influent in order to provide the maximum information for selecting treatment technology. Some of the topics covered in this presentation will include primary and secondary parameters that should be measured, sampling locations and total versus soluble parameter properties. If there is a treatment technology that is thought be the right technology or its appropriateness needs to be evaluated, some additional parameters for these evaluations will also be discussed.
The third presentation will provide historic perspective of industrial wastewater treatment while concentrating on new advances in biological treatment. These will include treatment requirements due to stringent effluent quality requirements for total nitrogen and phosphorus. The presentation will address issues such as nutrient limitation, inhibition and toxicity to certain processes. Advances in high rate biological processes and novel membrane technologies will also be presented. The speaker will also delineate methods for identifying the presence of refractory organics in influent and the treatment of these will be discussed in the fifth presentation by Dr. Bowers.
More industries prefer to discharge to POTWs, thus creating a need for pretreatment limits from POTWs. The fourth presentation will discuss how these SIU permits are developed while simultaneously considering a wide array of industrial discharges to POTW. The synergistic effects due to the presence of inhibitory and toxic chemicals as well as the presence of metal ions will be discussed.
The fifth presentation by will address how to deal with influent containing refractory organics. The presentation will cover oxidative technologies for treating refractory wastewater influent to make it amenable for biodegradation. The presentation will discuss challenges encountered during the selection of oxidative process and advantages and disadvantages of each process.
The final presentation will discuss technologies for removal of metals from wastewater in order to make effluent suitable for discharge to public waters. The pros and cons of choosing different treatment locations will also be examined. The treatment technology selection and concentration of metal that are achievable in effluents for various metals will be discussed.
All attendees should be prepared to study a treatment challenge they face day to day. Attendees will be divided in the four separate groups to tackle a case study. Workshop speakers will bring a case study. Case studies will cover: treat biodegradable organics; treat refractory organics; metal containing wastewater treatment; and, industrial contribution to POTWs.
