Challenges of Aerobic Treatment Ponds

September 30th, 2019|Comments Off on Challenges of Aerobic Treatment Ponds

Back in the early days of the Clean Water Act, pond systems were the ticket for industrial production facilities located in remote areas where municipal treatment was not available. Today pond treatment systems are subject to more stringent discharge limits, often making them more of a burden than an asset. Operators, engineers, and equipment manufactures continue to come up with new and innovative ways to keep these treatment systems operational and within compliance. However, these data systems have significant challenges compared to modern mechanical treatment options. Space Requirements To [...]

Managing Your High Strength Wastewater: What You Need to Know

July 1st, 2019|Comments Off on Managing Your High Strength Wastewater: What You Need to Know

All food and beverage production and packaging facilities generate wastewater during their production process. The wastewater produced has varying characteristics of organic content, pH, temperature, or toxicity. At times, the characteristics change nearly instantly, and may be caused by product changeover, batch discharge of brines, sanitation processes, power outages, or human error. The rapid change of wastewater character from these events can be troublesome and cause wastewater treatment system inhibition or upset conditions. When high strength waste (HSW) inhibits wastewater treatment processes, it may put the facility at risk [...]

Cooling Your Wastewater: 5 Methods to Consider to Achieve Thermal Compliance

February 26th, 2019|0 Comments

2010 was a significant year for increasing stringent limitations for all direct dischargers to Wisconsin Waterways, which included ultra-low phosphorus requirements and strict temperature regulations. While both of these regulations are designed to protect natural resources throughout the state complying with them is becoming increasingly difficult for dischargers. With much more stringent regulations in effect, issuance of permits dropped significantly until 2013. Since then,  most discharge permits (new and re-issued) have included a compliance schedule, giving facilities approximately 4 years to implement changes and achieve compliance with new thermal limits. [...]

5 Tips for Surviving the Cold While Working Outdoors

January 25th, 2019|0 Comments

Winter has finally arrived here in Wisconsin, with significant snow fall earlier this week followed by extreme cold temperatures. I dread even having to walk outside to my car in temperatures that feel like -30 degrees – the idea of working outside in such cold sounds like pure torture. Feelings aside, there is real, significant danger associated with working outside in such extreme cold. It is essential to protect yourself when working outdoors as prolonged exposure to extremely cold weather can result in severe consequences such as frostbite, dehydration, [...]

3 Alternatives to Construction for Thermal Compliance

November 21st, 2018|0 Comments

Surface water dischargers throughout the country are required to comply with the limitations set forth in their discharge permit. In many states, this includes thermal limitations which were implemented to protect fish and other aquatic life from mortality, immobilization, loss of equilibrium, impaired growth, adverse reproductive effects, and other sub-lethal effects.   In Wisconsin, NR 102 Subchapter II, which was finalized in September 2010, instituted water quality standards for temperature for the first time. For the next two years, discharge permit reissuances slowed considerably as the Wisconsin Department of [...]
