Groundwater Remediation
12/1/2020
Good quality groundwater is an important natural resource. It provides drinking water for the public as well as process water for industrial applications. Groundwater can become contaminated through a number of ways including improper handling of process chemicals or disposal of wastes.

Organics Aren’t Invisible: A Guide for Simple Online Monitoring
5/13/2019
Control of dissolved organics has been one of the highest priority concerns for most water treatment plants for over 20 years. Organics monitoring is an even more critical issue today in the face of more stringent regulations and concerns around trace organics, emerging contaminants, and even counter-terrorism or water security. Despite the critical need, many plants still rely primarily on turbidity for monitoring and process control.

A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water
4/5/2013
Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).

Removal Of PFCs With Activated Carbon
12/30/2013
In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

On-Line Phosphorous Measurement Takes The Guesswork Out Of Alum Treatment
7/16/2013
Phosphorous promotes eutrophication in surface waters and helps create conditions for algal blooming and oxygen depletion. Some phosphorous removal can occur naturally in a conventional biological wastewater treatment facility, but the result is not reliably compliant with increasingly strict limits on permissible phosphate levels in effluent discharged to receiving streams, ponds and lakes.

Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives
4/1/2017
Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

Dissolved Oxygen Measurement
11/11/2013
One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

Application Note: Ozone Measurement In Potable Water
3/1/2010
Ozone is a powerful oxidizing agent that can be used to destroy the organic compounds that affect the taste and odor of potable water. Environmental concerns have led to increased use of ozone because, unlike chlorine, it does not form hazardous by-products.
