Drinking Water Utilities

For Water Infrastructure: Supplied Water

Water sources such as rivers and lakes, which provide clean water,
are important elements that support people's lives. Highly accurate measuring instruments are required for managing the quality of drinking water.
Based on the technology it has developed through industrial water quality instruments, HORIBA provides a wide range of measurement systems, including a lineup of more highly sensitive water quality analyzers for supplied water,
and systems for monitoring water quality, which offer a package of measuring instruments for sites that require environmental monitoring.

In this application note, the authors present a novel, rapid method for identifying low concentrations of oil contamination in process water using Fluorescence Excitation Emission Matrix (FEEM) combined with Parallel Factor Analysis (PARAFAC). This method allows for quick detection and analysis of oil contaminants in process water, offering a practical solution for industries where timely intervention is crucial.

Comparison of the model and actual periodic measurements of THM species in finished water (A) and raw water (B).

This application note describes a rapid, sensitive nondestructive disinfection byproducts (DBP) prediction method using patented simultaneous Absorbance-Transmittance and fluorescence Excitation-Emission Matrix (A-TEEM) spectroscopy.

This application note describes the use of the Aqualog for monitoring regulated Dissolved Organic Matter (DOM) and disinfection by-product issues for drinking water treatment.

This study describes the application of simultaneous absorbance and fluorescence excitation-emission matrix (EEM) analysis for the purpose of identification and classification of freshwater planktonic algal species.

Water travels through the environment carrying dissolved organic matter (DOM), made up of various chemical compounds, which have entered the water column from many sources.

The concern of water contamination from nanoplastics (≤ 1 µm) is a study receiving close scrutiny from FDA and EPA alike. Nanoparticles can gain access through inhalation, ingestion, or dermal exposure and have greater cellular uptake than those bigger in size. Nanoparticles subsequently pose a greater impact on health.

Analysis of Chlorine, Bromine and Iodine in Water using ICP-AES

The analysis of Br, Cl, and I is possible with ICP-AES at low limits of detection due to an adaptation of the instrument. This adaptation doesn't affect the determination of other elements and will generally improve analytical performance for any elemental lines below 200 nm for example, Pb at 168 nm.

Petroleum and Oil Spill Products

Global drinking water sources remain prone to carcinogenic petroleum product contaminations due to lack of detection capacity at or before treatment plant intake. The Aqualog A-TEEM method provides a reliable optical detection of these compounds at low quantities discriminating from the highly absorbing and fluorescent backgrounds of natural Dissolved Organic Matter (DOM) components.
