Water Quality - Constituents That Impact Industrial Operations (Part 1)

Sewage treatment plants are only one of many applications
where water quality is a concern.

Of all the raw materials available for human consumption – aside from the air we breathe – the most vital component of life on earth is water. In addition to the global need for humans to drink water in order to survive, the use of water is essential in a myriad of industries relating to process control. Whether the goal is the production or monitoring of pure water for industrial use, or the processing of wastewater, the ability to measure the presence and level of certain chemical constituents of water is necessary for success.

In order to use water properly, industrial professionals combine state of the art analyzers with technical expertise to evaluate water quality for use or disposal. Two essential values of process control are ensuring elements of a control system are accurate and secure, and, furthermore, that they are accurate and secure for each product every time. By properly vetting water in industry, engineers and other personnel in fields such as pharmaceuticals, chemical, food & beverage, brewing, power, and microelectronics are able to maintain standards of production excellence and conform with regulatory requirements related to water quality.

The amount of dissolved oxygen present in water can correlate with the degree of movement at an air-water interface, also being impacted by pressure, temperature, and salinity. Excessive or deficient dissolved oxygen levels in industrial process waters may have an impact on process performance or end product quality. Likely, the most common application for dissolved oxygen measurement is in the evaluation of wastewater for biological oxygen demand. The primary function of dissolved oxygen in wastewater is to enable and enhance the oxidation of organic material by aerobic bacteria, a necessary step in treatment.

To measure dissolved oxygen, specialized sensors and companion instruments are employed that require careful maintenance and trained technical operators. The level of measurement precision varies depending on the industry employing the technology, with numerous applications also being found in the food & beverage and pharmaceutical industries. In-line continuous measurement is used in wastewater processing to determine if the dissolved oxygen remains in a range that supports the bacteria necessary for biodegradation.

Chloride concentration in wastewater is strictly regulated. Industrial and commercial operation effluent can be regulated with respect to allowable chloride content. While commonly found in both streams and wastewater, chlorides, in large amounts, can present challenges to water utilization or processing facilities. Chloride levels impact corrosion, conductivity, and taste (for industries in which such a variable is paramount). In a process system, having an essential component marred due to elevated quantities of a substance could reverberate into any end-product being manufactured. Chloride analyzers, some of which can also detect and monitor other water characteristics, serve as important tools for water consuming facilities to meet regulatory standards for effluent discharge or internal quality standards for recycling.

There are other constituents of what we refer to as “water” that are subject to measurement and monitoring for a range of institutional, industrial, and municipal applications. Those will be explored in the next part of this article series.

Learn From History - Explosion at Texas Facility

Industrial accidents range in severity and impact from minuscule to catastrophic. As operators, owners, or technicians involved with industrial operations, we all have a degree of moral, ethical, and legal responsibility to conduct our work in a manner that does not unduly endanger personnel, property, or the environment. Maintaining a diligent safety stance can be helped by reviewing industrial accidents at other facilities. There is much to learn from these unfortunate events, even when they happen in an industry that may seem somewhat removed from your own.

The U.S. Chemical Safety Board, or CSB, is an independent federal agency that investigates industrial chemical accidents. Below, find one of their video reenactments of an explosion that occurred in Texas in 2013, along with their findings regarding the cause of the incident. Check out the video and sharpen your senses to evaluate potential trouble spots in your own operation.

Industrial Wireless Communications - Think About Where You Can Use It

Wireless communications applications with beneficial impact
are everywhere, Imaginative thinking is needed.

Analynk builds equipment that empowers anyone with an industrial process control application to make signal connections from sensors to controllers or recorders over distances not practically cabled. The cost and available scale of this technology has reached a level where smaller companies can incorporate it into their operations to increase functionality and efficiency. If you have not done so already, it is time to become familiar with the application basics of this technology and start evaluating your operations for ways to beneficially use industrial wireless communications.

In a simplified fashion, here is how you do it.

• Identify what you want to measure. Typical examples include temperature, pressure, contact closure, or anything else for which a sensing or detecting device is available.
• Find the device most suited for your measurement. It will be convenient to use a device providing a commonly used output signal. Examples include 4-20 ma, 0-5 VDC, and others.
• Select the communications band that best suits your application. Short distances, up to several miles, often use 900 MHz or 2.4 GHz. You can also use the cellular network or one of several satellite networks for extended coverage.
• Select a compatible transmitter, like those from Analynk, to convert the sensor output signal into digital form and transmit it across the network.
• Select a compatible receiver, also available from Analynk, to receive the transmitted signal and convert it back into the original signal form. This output signal will connect to your control or monitoring equipment.
• If you need to send a responding control signal back to the remote location, follow the same plan with the transmission and receiving equipment reversed.

The first time you do it, there will be some things to learn, progress may be a little slow. Once your first attempt is completed, you will understand what needs to be done and further implementation will proceed quickly. There are uncountable applications for this technology that can enable your organization to increase effectiveness, broaden the scope of your operation or service offering, and build a more efficient process. Data points that were previously out of reach are now accessible in real time. Knowing the capabilities of industrial wireless will enable you to recognize useful applications throughout your organization.

You can always contact the specialists at Analynk Wireless to discuss your potential applications. They will help you meet application challenges and get connected.
