How to Select an Effluent Treatment?
The first step is accurately gauging the total effluent volume and flow rate with a survey to size the treatment capacity properly. In parallel, estimate if your production processes or volumes could expand, meaning greater effluent generation. The treatment selected must have adequate capacity. Quantifying both the current flow requirements and potential increases lets us identify and design ...

What’s That Smell? Wastewater Edition
Sewage is not known for its pleasant aroma, but what exactly is that smell, and what causes it? The municipal wastewater treatment process can release odors in the collection and treatment process. Wastewater is mostly water, but it also contains organic and inorganic matter, bacteria, and other microorganisms. These all contribute to processes that release gases into the air that are unpleasant ...
