Seasonal water quality vs. flow relationships in a small regulated stream
The relationship of a water quality constituent with respect to flow measured at a stream monitoring station can give valuable information about the watershed and in-stream processes about the constituent in question. Seasonal dependency patterns often reveal relationships which would be unnoticed if all data are treated together. The aim of this study is to examine water quality constituent ...

Closed Circuit Coolers: Design with winter in mind
When outside temperatures fall below freezing, water inevitably forms into ice. Open cooling towers can be susceptible to freezing due to their inherent nature of operation. As a result, ice formation becomes a subject of management, not elimination. Fortunately, there are alternative solutions. Closed circuit coolers are used for a multitude of niche applications, but are ideal for evaporative ...

Automatic control valves: how to assess ACV applications
As automation and computers claimed a foothold in the operation and control of reservoirs and elevated water tanks, the industry moved the valve control from mechanical automatic control valves (ACV) to actuated butterfly and ball valves. The primary reason? Actuators can be controlled by SCADA systems, which have been almost universally implemented in modern water systems. Because of this, ...

CO2 degasification air stripping tower design - Case study
Background - Water Chemistry Controls the Design A common method to adjust pH of water - typically well water intended for potable use - is to pass the water through a packed tower. Such towers intended to degas the water was also commonly called 'air strippers'. This is because the water is passed down over a bed of 'packing1 as air is blown into the bottom of the tower to pass up and out of the ...

Forests for water: Exploring payments for watershed services in the U.S. south
The forested watersheds of the southern United States provide a number of benefits—including water flow regulation, flood control, water purification, erosion control, and freshwater supply—to the region’s citizens, communities, and businesses. The loss and degradation of forests can reduce their ability to provide these watershed-related ecosystem services. Payments for ...

What is the Geocell used for?
As a kind of building material, geotechnical materials have been used in European and American engineering buildings as early as the 1950s. Today, geotechnical products have developed into eight series: geotextiles, geogrids, geonets, geomatics(geosynthetic clay liner), geomembranes, geocells, geocomposite materials, and other related new geosynthetic products. Geocells has become more and more ...
