One analyser for carbon contamination and nitrogen/phosphorus nutrient levels in water
Contamination levels in water affect decisions on treatment and reuse. With data on contamination and nutrient levels, water managers can make the most efficient and cost-effective decisions on treatment and reuse of valuable water resources.
• Improve treatment and reuse decisions using accurate and complete water quality information
• Reduce nutrient dosing costs while protecting critical treatment plants with correct C:N:P ratios
• Spend more time managing the plant and less time collecting data with a rugged, industrially designed online analyser for monitoring TOC, TN and TP
• Quickly detect product loss to save valuable product and minimise the risk of non-compliance by preventing excessive pollution discharge at the wastewater treatment plant
The Hach TOC analyser analyses every process sample completely and in detail to deliver reliable results.
Improve the wastewater treatment process
Detect changes in water quality in the most difficult samples directly with Total Organic Carbon (contamination), Total Nitrogen and Total Phosphorus analysis.
Reduce your environmental footprint
Comprehensive information about incoming sample composition enables advanced process control. Knowing TOC + TN and TP values lets you reduce utility usage and related costs. Optimising processes reduces the environmental impact of effluent and minimises the risk of fines and reputational damage.
Protect your Wastewater Treatment Plant and Wastewater Recycling Plant
TOC is commonly used as a fast and reliable analytical measure of water quality. TOC levels are often correlated with delayed water quality measures such as Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD).
Superior reliability
With a certified uptime of 99.86%, have critical process information when you need it most. In most applications maintenance is performed twice a year.
