Open channel flow monitoring is a method of measuring water flow rates in irrigation channels, streams, and storm water systems. It’s also used in wastewater processing for monitoring the effluent discharge. In most applications for open channel flow, weirs and flumes are used. For those of us not familiar, weirs and flumes concentrate the flow into a known cross sectional area, relating an accurate level reading to an accurate flow rate. The height of the water in the channel, going over the weir or flume, is directly proportional to the flow rate. Continue reading “Open Channel Flow Monitoring”
Maintaining efficiency in wet chemical scrubbers has become one of the most important missions of current APC facilities due to urban growth and plant expansion/modernization projects as good stewards of the community. Systems often run above the 90% efficiency mark with the help of accurate make-up water control instruments. Continue reading “Sump Level Make-Up Water Controls in Wet Chemical Scrubbers”
Every day, billions of gallons of wastewater are collected from our homes, businesses, and industries. Wastewater is exactly what it sounds like: water that has already been used and disposed of via a tub, toilet, sink, or storm drains. Because it is full of contaminants that make the water no longer suitable for use, it is collected in the sewer system and delivered to plants for treatment to make the water safe to be returned to the environment. Continue reading “What is Wastewater, and How is it Treated?”
Question: I have had difficulty reliably measuring the level in lift stations and was wondering what you have for such an application? Continue reading “Ask the Expert – Measuring Wastewater Level with a PBLT2 Submersible Level Transmitter”
For decades, the municipal Water and Wastewater Market has been a focal point for many product lines associated with the Mercoid brand. With Dwyer’s ever expanding product lines we have been able to offer a diverse array of instruments to monitor and control pressure, level, flow, humidity, and data logging. A growing application with similar demands is landfill leachate pumping, where Mercoid has been able to successfully implement several products.
