Industrial water analysis: From point of entry to waste water

The majority of industrial manufacturing processes, such as distilling crude oil to refined petroleum products, paper production from wood chips, cracking larger naphtha molecules to ethylene, making polymers from ethylene oxide, power generation, and making high speed microprocessors, all need large quantities of high purity water.

Maintaining a sustainable water program is essential for all major water consuming industries. Routine water testing and monitoring—from source water to waste water discharge—is critical for safe and profitable operation. Routine process water analysis is critical to eliminate corrosion and scaling that can damage valuable industrial components and to ensure regulatory compliance.

Industrial Water Analysis Infographic

Process water quality is an integral part of the industrial manufacturing process. Water quality can change as it passes through a delivery or re-circulation system, so it is important to check for various parameters at point of use—i.e., where it enters the boiler or pretreatment system. Each water sample needs to be tested for multiple parameters, usually by multiple techniques to make sure the produced and reused process water is free of contamination. The table below summarizes the process critical water analysis parameters from feed water to waste water.

By understanding the level of contamination, facility operators can take actions to reduce the damage from corrosion, deposition, and scaling. Industrial water testing is, therefore, essential for quality control and process optimization. Multi-component analysis of corrosive ions, scaling ions, corrosion inhibitors, and corrosion indicators, provides detailed information for successful and predictable utility operation.

Solution for routine and comprehensive water analysis

Recycling and reusing process water increases the sample load of analytical testing labs. Utilizing the proper instruments to help ease your most critical daily applications is the key—regardless of whether you’re in the industrial or in commercial testing lab. Typically, multiple automated traditional wet chemistry analytical methods such as titration, spectrophotometer, ion meter, pH/conductivity meter, and flow injection analyzers (FIA) are used to test several process water parameters. Traditional automated techniques, such as titration and continuous flow analysis, are relatively inflexible: dedicated modules are used for specific chemistries, and dedicated skilled technicians are needed for instrument operation and maintenance. Analyses are time consuming and generate a large volume of reagent waste.

To eliminate corrosion and scaling that can damage valuable industrial components and to ensure regulatory compliance, reliable water analysis must be performed continuously. Daily testing varying concentrations of multiple analytes like, corrosive anions, corrosion inhibitors, corrosion indicators from diverse water samples such as ground water, source water, cooling water, steam condensate, de-mineralized water and waste water puts a heavy burden on your lab resources. The solution to improved productivity is processing many parameters simultaneously with high-throughput analysis and walkaway operation. For industrial process water quality monitoring, Thermo Scientific Gallery and Gallery Plus Aqua Master discrete analyzers with ECM module, offer rapid multi parameter testing, unattended high throughput analysis of large sample numbers, and cover a wide concentration range for sample types of varying ionic strengths.

The ECM is an integrated part of the Gallery Aqua Master system and supports automated pH and conductivity measurements. It can measure both pH and conductivity simultaneously alongside the photometric testing. This module can be used for analysis of raw water, ground water, sea water, rainwater, municipal water, drinking water, sewage water, and wastewater. It is not suitable for measurement in pure water matrices such as DI water or steam condensate.

For laboratories that perform routine process water and wastewater analysis, Gallery and Gallery Plus Aqua Master systems with ECM module provide increased throughput while lowering the cost per analysis.

Ready-to-use reagent kits for water analysis

Save time by eliminating reagent preparation with the Thermo Scientific Gallery system reagents for environmental testing, such as water (clean water, wastewater, soil and sludge digests, effluents, and saline) and industrial (process water) analysis. With over 40 ready-to-use Gallery system reagents for environmental analysis, the kits include 1 to 3 reagents in 20 mL barcoded vials, allowing the necessary identification data, such as lot and expiration date, to be read automatically by the discrete analyzer's barcode reader. Automated dilutions make it possible to apply methods for a wide range of analyte concentrations and the test applications are based on recommended standard water and wastewater methods used in most countries. Save time and reduce errors by simplifying your analysis with the Gallery system reagents for environmental analysis.

Gallery and Gallery Plus Aqua Master discrete analyzers are easy to use, automated systems that allow laboratories to simplify their testing with the dual benefits of time and cost savings. All necessary analysis steps are automated, providing true walk-away time for the operator. Parallel determination of several analytes along with pH and conductivity from a single sample as well as the presence of several automated features ensures analytical efficiency.
