Money Down The Drain: The High Cost Of Poor Air Flow Metering
 

Activated sludge systems have been a cornerstone of wastewater treatment for over 100 years. This biological process uses suspended growth microorganisms to break down and consume organics and remove nutrients from the wastewater. The heart of the process takes place in aeration basins, where the microorganisms need to receive sufficient oxygen to stay alive.

The Challenges Of Combined Heat And Power Generation From Biogas
 

Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.

Two Processes, One Flow Metering Technology: The Benefits Of Standardization
 

Wastewater treatment facilities use multiple processes and a variety of equipment to produce water clean enough for reuse. Each process within the treatment train may serve a different function yet use the same or similar equipment. In such cases, standardizing equipment may be beneficial. For instance, standardizing gas flow meters offers several advantages. Let’s look at an activated sludge plant using anaerobic digestion for biosolids treatment as an example.

How To Extend The Life Of Your Wastewater Pumps
 

Wastewater treatment plants use numerous pumps in a variety of types and sizes to move water through the process. Depending on plant configuration, they may pump influent, activated sludge, thickened or digested sludge, biosolids, scum, filtrate, effluent, or reuse water. Each matrix has specific characteristics that engineers consider when designing pumping systems.
