Application Note

Airport De-icing Run-off.

Monitoring Run-off with TOC


Winter deicing operations result in airfield runoff containing glycol, fuel, oil, and other organic compounds. These contaminants must be monitored and collected for treatment. Collecting only the contaminated run-off keeps treatment costs to a minimum while assuring compliant discharge, and TOC or COD is typically measured to determine the organic load in the run-off.

Application Note

Hydrocarbons

Demystifying BOD, COD & TOC

Hydrocarbons are organic cabon compounds, and TOC analyzers are often used to monitor environmental discharge compliance or to monitor for product loss or detect spills.

This brief overview decribes how Total Organic Carbon Analyzes are used as Hydrocarbon Counters.

NitritoxMonitor

Toxicity

Early Toxicity Detection for WWTPs

ASP-Con

The Nitritox detects toxic events to protect the biomass in wastewater treatment plants.
Without this potection the operator faces the risk that nitrification inhibition will be identified too late. If BOD degradation remains unchanged while ammonia removal is inhibited for several days monitoring toxicity may be needed.

This supplimental information on the Nitritox Monitor shows spike detection, internal chemistry, and process sampling method.

ELOX

Chemical Oxygen Demand

Affordable COD Monitoring

ASP-Con

LAR's ELOX100 provides an affordable alternative for online COD analysis.

The Elox uses LAR's patented electrochemical method to produce OH-radicals as the oxidizing
agent. This enables the Elox to oxidize difficult substances more quickly, for a fast, accurate COD measurement.


 

BioMonitor

Biological Oxygen Demand

Supplimental Information

lnner workings of the BioMonitor are shown and explained, including Sludge Recycling option and wet chemistry.

System Advantages:
* Four-minute BOD
* Simultaneous BOD and Activated Sludge Respiration (ASR)
* Replicates Conditions in Your Plant
* High Operational Safety

Ammonitor

Ammonia

Monitor Ammonia in Wastewater

For industrial and municipal wastewater treatment plants (WWTP)

The Ammonitor is suitable for Ammonia measurement in sewage treatment and industrial wastewater treatment applications. The ranging allows the determination of Ammonia values between up to 1,000 mg/L. The wide measuring range fully covers the needs for monitoring and process control.

BioMonitor

Biological Oxygen Demand

Rapid BOD with Your Plant's Sludge

ASP-Con

The BioMonitor works like a miniature wastewater treatment plant, using sludge drawn directly from your basins (or recirculated when no sampling is available) to provide rapid BOD measurements (only four minutes) that correlate to BOD5.
