Summary:
Jon Vanyo, Senior Engineer with the Minnesota Technical Assistance Program, provided an overview of
wastewater optimization and MnTAP’s pollution prevention approach. He
introduced MnTAP’s role in offering free, non-regulatory technical assistance
to help Minnesota facilities improve efficiency, reduce environmental impacts,
and meet compliance goals.
Jon walked through the key stages of wastewater treatment
including screening, clarification, aeration, and disinfection. He highlighted how biological processes and microbial management are essential to effective
treatment and shares strategies for reducing energy consumption, including
optimizing aeration systems and using variable frequency drives to better match
oxygen supply with microbial needs. The session also covered nutrient removal
techniques, comparing chemical treatment methods with biological nutrient
removal (BNR), which uses specialized microbes under controlled conditions to
remove nitrogen and phosphorus more efficiently.
Finally, Jon highlighted MnTAP’s intern program, which
places students in real-world projects across industries and municipalities. He
shared examples of successful intern-led projects that achieved significant
water and energy savings, and emphasized the importance of collaboration
between communities, businesses, and MnTAP to advance pollution prevention and
resource efficiency.
