From Environmental Management: Wastewater and Groundwater Treatment
The environmental watchdogs are regularly sharpening their teeth. Most years there is an upgrade in the details of environmental regulations such that past compliance is no guarantee that a new installation will pass. The goal of regulations can be summed up as: “No more leaks from underground storage tanks and associated pipe.” Secondary containment is the way to achieve this laudable objective. Pipes and tanks inevitably leak. Surrounding them with a shell to contain the leak protects the environment. The life of such a secondary containment is measured in decades. Many regulations [1- 6] make it clear that piping systems must be upgraded, maintained and monitored to prevent leak events. More >>

Products & Services
Gas sensors interact with a gas to initiate the measurement of its concentration. The sensor then provides output to an instrument to display the measurements.
pH and oxidation reduction potential (ORP) instruments measure or monitor pH (relative concentration of hydrogen ions [H+] in a solution) as well as ORP.
Clarifiers and screens are used to remove solids from liquids through gravity settling or a mechanical screening process.
Adsorption equipment removes contaminants from gases and liquids by means of chemical adsorption.
Softeners remove the hard calcium and magnesium minerals from water .
