Dissolved Oxygen Measurement for Craft Breweries

Oxygen is both friend and enemy to the brewer!

It gives yeast what it wants to breathe and survive during the fermentation process and then becomes your main antagonist after the yeast has done its job.

Any process or transfer where beer becomes exposed to oxygen post-fermentation is an opportunity for oxygen to cause staling, muting, and shelf-life reduction. One example is the packaging process. The added oxygen resulting from placing the beer in cans, kegs, or bottles can affect the final product's consistency and taste.

As a brewer, you want to concentrate on producing the best-tasting beer. Therefore, it is critical to know how oxygen affects the brewing process and how packaging can eventually impact your beer's taste. It will give you the trust you need to create award-winning flavors that customers will enjoy, no matter how long the beer sits on the shelf.

METTLER TOLEDO Process Analytics offers the most accurate and cost-effective solutions for measuring dissolved oxygen in brewing applications. These robust optical dissolved oxygen sensors are durable and require minimal maintenance.

Eliminate Delayed Oxygen Measurement Safety Risk in Your Process Gas Analyzer

Having a car alarm that goes off 15 seconds after a break-in puts you at risk of property damage and significant loss. If you wouldn't take this risk with your car, why take it in your process plant?

If you're using an extractive oxygen analyzer that requires sampling and conditioning to prevent explosive conditions, that's exactly what you're getting - an alert up to 60 seconds after an oxygen build up is started. Using an extractive analyzer that requires sampling and conditioning means it's impossible to get real-time information. Measurements are delayed by up to a minute as the sample travels through pipes to the analyzer. In addition oxygen in the sample can be diluted by the gas ahead of and behind it, resulting in a falsely flat excursion curve. An alarm threshold may not be met when it should, so you get one, perhaps inaccurate, result in one minute.

Eliminate the risk. Get continuous real-time measurement. The GPro 500 tunable diode laser gas analyzer from Mettler-Toledo measures in-situ, without the need for sampling and conditioning. It provides continuous measurement and safety-critical applications, so you'll know about oxygen excursions immediately. Don't leave your plant safety up to delayed measurement. Rethink safety. Rethink gas analytics.

METTLER TOLEDO's GPro 500 Series Tunable Diode Laser Gas Sensor

The use of Tunable Diode Laser (TDL) gas sensors is becoming more and more common in industrial processes. This is because they measure directly in the process gas stream without drift or cross-interference and are far more economical to purchase, install and maintain than other gas analyzer types. TDLs use a measurement technology called absorption spectroscopy: they output a beam of laser light at the same frequency that the gas to be measured absorbs light. The TDL analyzes the light after it has passed through the gas stream and calculates the quantity of the target gas in the stream.

Most TDLs are comprised of two parts: the laser source unit and a receiving/analyzing unit. These parts must be installed directly opposite each other, which is not always easy and misaligned can often occur. METTLER TOLEDO's GPro 500 Series solves this by combining both parts in a single unit. A probe attached to the GPro 500 sensor protrudes into the gas stream. A three-sided mirror at the end of the probe directs the beam back through the probe to the receiver, so alignment is always perfect.

The series is available with a wide range of different probes and adaptions that allow the GPro 500 to be placed wherever required in a process. These include: 

• a probe with a filter to prevent dust ingress
• a wafer probe for narrow (2") pipes
• an extractive cell for use with sampling and conditioning systems
• a White cell for trace level detection

Using a modular design, the GPro 500 tunable diode laser gas analyzer allows you to select the process adaption that fits your application, and match it with the parameter that you need to measure. We offer sensors that measure  a variety of gases including Carbon Dioxide (CO₂), Carbon Monoxide (CO), Hydrogen Chloride (HCl), Hydrogen Sulfide (H₂S), Moisture, Ammonia (NH₃), Methane (CH₄) and Oxygen (O₂). 

The GPro 500 does not require maintenance-prone extractive and conditioning systems. This means that you receive consistent performance from your tunable diode laser gas analyzer without the downtime and cost associated with these traditional systems. You achieve reliable uptime, critical in safety applications, at a reduced cost of ownership.

The Preparation of Pharmaceutical Waters

While the public considers municipal water to be “pure”, the pharmaceutical market considers municipal water (feedwater) just the starting point in producing pure water. Water is the most widely used excipient in pharmaceutical manufacturing, and pharmaceutical water is a multi-functional resource, crossing all disciplines in the pharmaceutical industry. Water is used as a raw material, solvent, ingredient, reagent, and clean-ing agent, and is produced in a variety of “pure” forms.

Purified Water (PW), Highly Purified Water (HPW), and Water for Injection (WFI) used in pharmaceutical processes are produced on site from the local potable water, which has been produced by the treatment of the feedwater.

Analytical Measurement Solutions for Optimization of Your Brewing Process

Stages of brewing and areas for process measurement.

The beer market is currently experiencing an intense globalization process, reflected in escalating competitive and cost pressures. In addition to this, there is growing diversification into new, innovative beverages that demand maximum production flexibility. The time to market is becoming ever shorter, and product quality has to be guaranteed at a consistently high level, accompanied by an increase in productivity.

In-line Measurements in the Brew House

Proper process control plays a vital role in determining the flavor, foam stability, and color of the finished beer. The relative measurement sensors are exposed to high temperatures, and solid particles and turbidity constituents, and must be capable of surviving multiple CIP cycles.

Turbidity Sensor

Measurements in the Fermentation and Storage Cellars

At standard fermentation temperatures, propagation of microorganisms is detrimental to the beer. In order to prevent this from occurring, hygienic plant design and use of materials resistant to CIP solutions are important criteria, as they are for in-line sensors.

DO and CO2 Sensors

Measurements in CIP Systems

The economic use of fresh water, as well as the multiple use of cleaning solutions, present a further basis for achieving overall cost reduction in line with the strive for greater efficiency of the brewing process. Here also, in-line systems are of help in monitoring and optimizing the relative sub-processes.

Measurements in Wastewater Treatment Facilities

Fouling of sensors in wastewater leads to uncertainty about the measurement results and can even result in measurement system failure. METTLER TOLEDO provides efficient and practical solutions in the wastewater treatment areas as well.

Industrial Corrosion Protection Through Chemical Treatment

"An ounce of prevention is worth a pound of cure", particularly when dealing with corrosion and it's effects on process equipment. Production downtime, safety concerns, environmental damage and personnel health all outweigh the obvious repair and replacement cost of the damaged equipment. All taken, the annual costs due to corrosion are estimated in the process and power industries are estimated to be around $750 billion globally.

Exterior treatments, such as painting and specialized coatings provide satisfactory results to maintain structural integrity. However, internal protection of process equipment requires a different approach. Building equipment from exotic materials which are immune from corrosion exceed any practical concept of reasonable cost. Another, much more reasonable approach is corrosion protection based on chemical treatment.

This guide, courtesy of Mettler-Toledo Process Analytics shows you the role in-line analytics play in keeping corrosion under control and avoiding unnecessary chemicals consumption in chemical plants, refineries, power and Cogen facilities.

Learn How a pH Sensor Works

pH Sensor (Mettler)

The video below will provide you with a basic visual understanding of the design of pH sensors and the principles behind pH probe operation. Before viewing the video, here are some pH basics:

What is pH measurement?

pH (potential of hydrogen) is a figure used to express the acidity or alkalinity of a solution on a logarithmic scale. On this scale 7 is neutral; lower values are more acidic and higher values are more alkaline, with a maximum measurement of 14. In process applications, pH is generally measured with an inline pH probe, the most common being the glass combination electrode. Additionally, an inline pH probe generally requires a process adaption, cable and transmitter.

How does a pH probe work?

A typical combination pH probe is made up of two separate electrodes built into one, a pH sensing electrode, and a reference electrode. In the simplest terms, a pH sensing electrode uses a special pH sensing glass membrane. H+ ions permeate the membrane creating a charge. The potential between the two electrodes is the measurement of hydrogen ions in the solution, giving the measure of pH. For more details, download the free pH Theory Guide.

What is the difference between a pH probe, a pH sensor and a pH electrode?

Absolutely nothing! The three terms are used interchangeably in the industry. They can be used for probes that are used in-process or in laboratory measurement. You may also hear the term "pH meter". This can be used for a piece of laboratory equipment, or the term pH meter can also be used to mean the combination of an inline pH probe, cable and transmitter.

Total Organic Carbon, or TOC, is one of several common water purity measurements. Purified water use in power generation, semiconductor manufacturing, and pharmaceutical production all depend upon minimum standards of quality to avoid adverse impact on process output or operation. Elevated levels of carbon compounds in purified process water indicates that water treatment equipment is not performing properly and needs attention.

TOC measurement involves oxidation of carbon compounds in the presence of UV light and a measurement of sample conductivity. Processing of the raw measurement yields a value for total organic carbon. Analytical instruments  that lessen the need for human involvement and deliver rapid and accurate results are preferred. Mettler Toledo provides an advanced solution for TOC measurement with it 5000TOCi analyzer.

Continuous Microbial Monitoring For Process Water

Real time microbial monitoring for process water builds
quality and production levels.

Monitoring process water microbial counts in the pharmaceutical industry has traditionally been a time consuming, hands-on operation. Sample preparation, plate counting, stains, reagents, and the time required to get results has kept microbial monitoring a cumbersome task that provides only snapshots of the process water quality at the time of sampling.

The Thornton Model 7000RMS from Mettler Toledo, a continuous on-line microbial monitoring system for purified water and water for injection, uses advanced laser based technology to provide immediate detection and quantification of microorganisms. Particles as small as .52 microns can be detected, and the monitor uses recent advancements in spectroscopic technology to differentiate between microbial and inert particles.

The 7000RMS puts on-line analytics for microbial contamination on the same timeline as TOC and conductivity, with all three critical aspects now subject to real time measurement.

Water Quality Analysis – Constituent Survey (Part 2)

Sewage treatment is but one area where water quality
measurement is employed

It would be difficult to understate the role and importance of water in industrial processing, even our own biological existence. In the first installment of this series, the roles of dissolved oxygen and chlorides were covered.

Continuing the examination of water quality monitoring in municipal and industrial processes, another key variable which requires monitoring for industrial water use is sulfate. Sulfate is a combination of sulfur and oxygen, salts of sulfuric acid. Similarly to chlorides, they can impact water utilization processes due to their capability for corrosion. The power generation industry is particularly attuned to the role of sulfates in their steam cycle, as should be any boiler operator. Minerals can concentrate in steam drums and accelerate corrosion. Thanks to advancements in monitoring technology, instruments are available which monitor for both chlorides (covered in the previous installment in this series) and sulfates with minimal supervision needed by the operator, ensuring accurate detection of constituent levels outside of an acceptable range. Ionic separation technologies precisely appraise the amount of sulfate ions in the stream, allowing for continuous evaluation and for corrective action to be taken early-on, avoiding expensive repairs and downtime.

Another substance worthy of measurement and monitoring in process water is sodium. Pure water production equipment, specifically cation exchange units, can be performance monitored with an online sodium analyzer. Output from the cation bed containing sodium, an indication of deteriorating performance, can be diverted and the bed regenerated. Steam production and power generation operations also benefit from sodium monitoring in an effort to combat corrosion in turbines, steam tubes, and other components. Sodium analyzers are very sensitive, able to detect trace levels.

Ammonia is comprised of nitrogen and hydrogen and, while colorless, carries a distinct odor. Industries such as agriculture utilize ammonia for fertilizing purposes, and many other specializations, including food processing, chemical synthesis, and metal finishing, utilize ammonia for their procedural and product-oriented needs. An essential understanding of ammonia, however, includes the fact that the chemical is deadly to many forms of aquatic life. Removing ammonia from industrial wastewater is a processing burden of many industries due to the environmental toxicity.

Methods for removing ammonia from wastewater include a biological treatment method called ‘conventional activated sludge’, aeration, sequencing batch reactor, and ion exchange. Several methods exist for in-line or sample based measurement of ammonia concentration in water. Each has particular procedures, dependencies, and limitations which must be considered for each application in order to put the most useful measurement method into operation.

As water is an essential part of almost every facet of human endeavor and the environment in which we all dwell, the study and application of related analytics is an important component of many water based processes. The variety of compounds which can be considered contaminants or harmful elements when dissolved or contained in water presents multiple challenges for engineers and process operators.
