What Is Wastewater Treatment?

Waste activated sludge is pumped into this pond for bacteria to munch onCommercial wastewater occupies its own strange space between residential wastewater and industrial wastewater. While the mixture of residential wastewater may vary from house to house and neighborhood to neighborhood, the basic sources are the same: toilets, sinks, bathtubs and showers, laundry equipment, and kitchen sinks and dishwashers. And industrial wastewater varies from location to location based on both scale and chemical make-up. But commercial wastewater is just different...

Water and Wastewater in Industrial Settings

Capturing rainwater in a collection tankWater and wastewater are often used as shorthand for culinary water delivery and sewage transportation and treatment systems, which works well from a utilities and residential/commercial stand point. But industrial water users have a much broader concept of both (clean) water and wastewater. Rather than just potable water, "clean water" can be any water that has not yet been used, no matter what the intended purpose. "Wastewater," then, is any post-use water, not just raw sewage.

5 Tips On Using An Ultrasonic Level Sensor In A Lift Station

gated wastewater lift stationLift stations are an essential component to municipal water and wastewater systems. Without them, many urban centers throughout the world would simply not exist. So keeping them in operation and performing properly is absolutely vital.

Lift stations that aren’t performing properly could spell disaster, especially if an overflow occurs. In addition to the unsanitary conditions and property damage an overflow creates, there is a hefty fine imposed by the EPA (think tens of thousands of dollars per day). Therefore, monitoring the water level in the station is critical. Level sensors can be used to trip alarms or turn on/off pumps automatically if an alarm condition exists.

There are a variety of instruments available to use for lift station level monitoring...

Submersible Pressure Transducers in Lift Stations: Pros and Cons

Submersible pressure transducers measure the liquid pressure exerted by the volume aboveContinuous measurement in a lift station can come from a variety of sensors including ultrasonic, radar, level probes, and submersible pressure transducers. Each sensor technology has pros and cons. Today’s post will focus on the benefits and challenges of using a submersible pressure transducer.

A pressure measurement at the bottom of a tank can be used to determine liquid. Submersible pressure sensors are specifically designed for these types of measurements. When a submersible pressure sensor is used in a lift station, it must be robust enough to deal with the turbulence and debris that is often present. For this...
