OWEA Conference June 26, 2019Dave Rutowski – Hach Process Optimization

Evaluation of high precision in-situ analysis against benchtop lab analyzers

for process insight

Why do we need improved analysys?

• The Clean Water Action Plan provides a blueprint for Federal agencies to work with States and others stakeholders in restoring and protecting the Nation’s water resources.

• A key part of the Action Plan provides for expanded efforts to reduce nutrient over enrichment of waters.

• The Great Lakes States have taken the lead in addressing nutrient pollution with limits in some areas to go down to 0.04 mg/L.

We have the technology to do more in less space

We have the technology to have unparalleled Clarity

IN THE FIELD, THINGS CAN GET MESSY…….

TREATMENT IS A HIGHLY VARIABLE OPERATION

Operator Questions -• What to measure – and why?• Where to measure it?• Is a daily grab sample representative, good enough?

– Hint: It is not• Is my plant running as designed?• Is my instrument giving me correct readings?• What do I do with the data?• Do the chemical, power savings matter?

– Hint: Absolutely7

TREATMENT IS A BUSINESS

• Retiring workforce - Institutional knowledgeis leaving the industry

• Changing Raw Materials – Factories come and go– Population changes– I&I / Pb mitigation

• Budget concerns

• Compliance regulations

• Data management– Common Platform / Language– Data Security– Remote Access

Everyone is being asked to do more with less but how?

• Lower concentrations of Ortho-P in a sample require a longer measurement path length.

Phosphax sc MR : b= 18mmPhosphax sc LR : b= 36mm

• Glass cuvette is expected to last the whole life time of the analyzer- More durable vs plastic cuvette in most analyzers.

• Glass cuvette is less prone to air bubbles compared to plastic cuvette in most analyzers.

• Double path length reduces effect of bubbles, if any.

• The Filtration Module prepares sample through two ultra-filtration membranes (0.15 µ)

• Modules are immersed in the process tank.

• Peristaltic pump pulls the sample through one filter at a time, allowing for optimal cleaning.

• Unit automatically cleans by forcing vigorous stream of air bubbles against sides of the filter modules.
