WASTEWATER PRODUCTS
The AquaPASS® process system is a leading-edge technology in the application of activated sludge for enhanced nutrient removal and wastewater reuse objectives.
The OPTIFLUX 7300 is a an electromagnetic flowmeter (EMF) for measuring very low conductivity liquids (≥0.05 μS/cm). The high-end meter is particularly suitable for applications with extremely adhesive and greasy media that tend to form an insulating film. It is also the first choice for applications involving high vibration and noise as well as oxidizing, abrasive or toxic chemicals. The leak-tight, vacuum and temperature resistant ceramic tube construction also complies with regulations of the food industry (FDA, EC1934/2004). Therefore, hygienic flow measurement with advanced requirements is another field of application.
Self-Cleaning Wedgewire Screen
The RSS Externally Fed Drum Screen is a reliable self-cleaning screen for both municipal wastewater operations as well as many industrial applications. This screening technology performs particularly well in wastewater with high oil or grease loadings as well as scum applications that can blind other types of screens.
Huber Technology, through its subsidiary Huber-Hydropress, is the inventor of the STEPSCREEN® concept. This design was unveiled in the early 1980’s to much acclaim and was readily adopted into the designs of well over 3,000 facilities worldwide since the STEPSCREEN® introduction.

Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix. -
