Parker THM Analyzer

Overall Agenda

• Disinfection Byproducts (DBP)

• Tools for Water Plant

• Control of DBP Formation

• Parker’s THM Analyzer

• Accuracy and Reliability of THM analysis

• Application of THM number

2

Disinfection Byproducts (DBP)

“Disinfection byproducts are formed when disinfectants used in water

treatment plants react with bromide and/or natural organic matter

(i.e., decaying vegetation) present in the source water.”

-US Environmental Protection Agency

3

Examples of DBP

•Trihalomethane (THM) •Haloacetic Acid (HAA5)

•Haloacetonitriles

•Bromate

•Chlorite

•NDMA

Disinfection By-product (DBP)

Formation

• DBP formation – Treatment Facility

-Make up and reactivity of organic carbon

-Aliphatic

-Aromatic

-Quantity, type and point of disinfection injection

-pH of the water

• DBP formation – Distribution System

-Retention time of water

-Temperature

-Characteristics of pipe deposit

4

Cl2/Chloramine + Organic Carbon = DBP

Tools Available to Water Plant

Operations

• Total Organic Carbon (TOC) Analysis

-Quantity of organic carbon

-No data on reactivity of organic carbon

-No data on the precursor of disinfection byproducts

• UV254

-Identifies aromaticity of organic carbon

-No identification of aliphatic organic carbon

• Turbidity

• pH

5

Control of DBP Formation

Conventional treatment options

• Type of coagulant

• Type of disinfectant

• Point of applying disinfectant

• pH adjustment

Missing parameters

• Identifying precursor of DBP

• Quantifying precursor of DBP

6

Missing Until Now…

Introducing the Parker THM Analyzer

7

For the first time, any water treatment plant has timely

access to simple, accurate, in-house THM Analysis

Parker THM Analyzer

8

Description:

Purge and Trap integrated with Gas Chromatograph Column and Surface

Acoustic Wave (SAW) Detector

Major Components:

•Sample Holder

•Preconcentrator/Trap

•GC Column

•SAW Detector

•Helium Gas

How it works:

1. Helium gas sparges THMs from water to trap

2. Trap desorbs THMs by heating & Helium carries THMs to GC Column

3. GC Column heated and Helium carries THMs to SAW

4. Software recognizes each THM component

5. Analyzed THM numbers are displayed on the touch screen

THM Analysis Made Easy

• Collect a water sample in a

40 mL EPA vial

• Pour it in the sample holder

• Screw the sample holder to

the analyzer

• Click “START” icon on the

laptop screen

• Name your sample

• Click “OK”

• Wait 28 minutes to get your

results
