Influent Monitoring for Organic and Toxic Loads

Take the Guesswork Out of Influent

Gain Insights into Organic and Nutrient Loads with Continuous Influent Monitoring

How do you know about changes to your influent? Your influent informs your processes – from anticipating incoming changes, to moving loads, to adjusting for incoming toxins. Early detection provides greater opportunity for proactive, effective process adjustments.

Your samples can tell you more. Hach^® is your partner for influent measurement solutions.

Influent monitoring tools from Hach give you the opportunity to dig deeper and gain additional insights into what’s happening in your influent. Our low-maintenance products can inform your process, with measurement capabilities including TOC, TN/TP and even toxicity.

Total Organic Carbon

Manage your treatment process efficiently by monitoring TOC in wastewater influent. TOC monitoring provides the insight necessary for swift process adjustment and opportunity redirect water as needed for retention and additional treatment.

Unlike BOD and COD, TOC can be measured quickly for real time adjustments without harmful or toxic byproduct.

Total Nitrogen and Total Phosphorous

It’s always challenging to meet discharge permits with very minimal control over what is coming in the influent. This can be more challenging when there are large industrial dischargers contributing to the influent stream. Download data sheet or explore eLearning opportunities.

BioTector B7000 provides continuous measurement of TOC, TN and TP in the influent.

Influent Toxicity

Toxic loads can throw off your process and lead to fines for your plant. Understand your upstream customers and combat toxins within your plant by knowing exactly when a toxic event occurs. Learn more about toxicity monitoring or watch the webinar.

Measure toxicity with EZ Series instruments. An accurate, online monitoring tool, the EZ7900 provides operators the information needed to maintain process stability and efficiency.
