Pumping advances address wastewater treatment basics

From floc formation to clump strengthening, sludge removal and disposal
Since the beginning of recorded time, societies have found ways to properly treat and dispose of water fouled through the course of its use. Meeting these needs has made the water/wastewater-treatment industry grow to $136 billion in revenues in 2011 in the United States, with an annual growth rate between 3.0% and 4.5%.

Must corrosion eat away at the process industries?

Corrosion is the long-time bane of heavy industry; space-age coatings may resolve some difficulties
Corroded pipe repair or replacement costs industry more than $7 billion per year, the National Association of Corrosion Engineers estimates. This figure can double when lost revenue, productivity, and spill or leak cleanup costs are tallied

All you’ve ever wanted to know about hose selection

Materials of construction, media compatibility and end connections are among considerations
Hose selection requires attention to application variables such as temperature, pressure and flow, as well as requirements ranging from chemical compatibility to drainability. Hoses “cost” more than their purchase price. Be sure to consider hose longevity, maintenance and replacement costs and other cost-of-ownership factors.

Going wireless can streamline position monitoring in explosive environments

Switches operate at extremely low voltage and current; feature an electro-dynamic energy generator
Monitoring a control valve’s position in process industries is typically done using conventional cabled position switches meant for normal manufacturing environments. While these devices address the functional requirements for sensing “open/closed” valve positions, inherent design characteristics may limit their life expectancy or make them unsuitable for use in potentially explosive gas/dust environments.
