Distillery Wastewater Byproducts Fuel Sustainability
5/29/2020
For distilleries, high levels of biochemical oxygen demand (BOD), nitrogen, total dissolved solids (TDS), and total suspended solids (TSS) put extra pressure on optimal biological treatment requirements. Here are some techniques that can help distillers put a little extra money in the bank while meeting the challenges of environmental discharge requirements.

Saving The Most Money On Wastewater Aeration: Bringing It All Together
4/28/2020
The power required for aeration is 50 to 60 percent of the electric bill for a municipal wastewater plant, sometimes accounting for up to 4 percent of the associated community’s total power. Energy efficiency is a critical factor in evaluating blower performance.

The Key To Accurate Waste Gas Flow Measurement
4/20/2020
Wastewater treatment facilities have a tremendous opportunity to utilize the biogas they generate to lower energy costs and minimize odors. However, the practice isn’t as widespread as it could be, as the precision gas flow and methane content readings required to optimize the process often clash with the misconception that biogas is messy and difficult to measure reliably. With the proper equipment, it is possible to accurately measure biogas to cut emissions and reduce or eliminate the energy bill.

Microwaving Sewage Waste May Make It Safe To Use As Fertilizer On Crops
1/29/2020
Biosolids — primarily dead bacteria — from sewage plants are usually dumped into landfills. However, they are rich in nutrients and can potentially be used as fertilizers. But farmers can’t just replace the normal fertilizers they use on agricultural soil with these biosolids. The reason is that they are often contaminated with toxic heavy metals like arsenic, lead, mercury and cadmium from industry. But dumping them in the landfills is wasting precious resources. So, what is the solution?
