With many in both industrial and municipal sectors looking to cut down on energy costs, the pressure falls on engineers to deliver systems that are both reliable and more energy efficient. Thankfully, the simple addition of variable frequency drives (VFDs) to mixing pumps can help achieve those goals.

Even the most careful engineer can overlook something that can impede oxygen transfer, including substances used during production, maintenance, and other stages of wastewater treatment. Failing to take these factors into account can cause the treatment systems to underperform and incur unexpected costs.

When it comes to wastewater aeration systems, experienced operators, consulting engineers, contractors, and executive decision-makers can appreciate the differences between a true workhorse, and one designed by a committee. Here are six important considerations for keeping new or upgraded designs from casting a dark shadow on aeration cost, convenience, and consistency.

In the past, many engineers designing wastewater treatment systems have strived to keep aeration tanks around 20’ deep or less due to limitations of aeration equipment. However, technological advancements have overcome past concerns, making deep aeration tanks an ideal solution for select wastewater applications.

Keeping pace with changing industrial wastewater treatment demands can raise multiple issues of oxygen demand, capital cost, and operating expense, often without the flexibility of taking basins out of service to upgrade to new levels of performance. Fortunately, there are alternatives for delivering more oxygen to treat more water.
