The next big thing is here and it’s the Industrial Internet of Things (IIoT). With pundits waxing philosophical on this big breakthrough, it’s hard to cut through the noise and understand what the IIoT actually is and how it applies to individual plants. I offer the following as a definition. The IIoT means collecting, interpreting, and applying data to actively improve processes or operations. To understand how the IIoT applies to a wastewater treatment plant, look no further than your front yard.
Water and wastewater treatment professionals are constantly looking for as much information as possible about the quality of their water. If knowledge is power, then understanding the properties of their water is key to running an effective and efficient facility.
Every day you hear things like “push your data into the cloud” or the newest functions of “cloud computing”. But what does this all mean? And what does it mean for utilities and facilities? Well, if you’re looking into Cloud SCADA, it can mean then difference between having to purchase and maintain software and hardware versus utilizing the internet and cloud computing platforms to serve as the framework for your SCADA system. That translates into time and money saved in the long run.
Sevierville, Tennessee is the hometown of internationally known entertainer Dolly Parton and is a popular gateway to the Great Smoky Mountains National Park. Located in Eastern Tennessee, the city has a population of 16,500 residents and is visited by 16 million tourists per year.
When first moved from water reservoirs, water contains materials that need to be treated and or removed. All microorganisms, flora and fauna waste, assorted dirt and insects all need to be dealt with before, water is fit for human consumption. It is understood that, water needs to make many detours in its path from raw supplies to the tap. All these detours start at the treatment plant. At the plant water goes though applications that remove contaminants such as suspended solids, bacteria, algae, fungi, and minerals such as iron and manganese. The final objective is to turn contaminated debris choked water into safe, drinking water.
Recently, ASCE released its Infrastructure Report Card, giving the nation’s drinking water infrastructure a D: in poor to fair condition and mostly below standard. Many water utilities and communities are doing the hard but necessary thing in finding the resources to upgrade their aging water infrastructure. And, for those in earthquake prone areas, hopefully considering an earthquake resistant system.
Manual tank gauging is a common oilfield activity that’s resulted in multiple worker deaths in recent years. By using work practice control, operators can reduce the risks it poses significantly.
When selecting a new analyzer for your plant, there are many different features to consider. One of those is the choice of how the instrument will be calibrated, namely between an inexpensive manual calibration and a more complex automatic calibration method. (To be clear, we will define automatic calibration as a feature that involves no operator intervention at the instrument.) Factors that influence this choice are financial, process, staff levels, and personal preference. Let’s explore each of those.
A timeline of 120 days. Construction in the middle of winter, when temperatures were frigid and snow covered the ground. Despite these challenges, Elite Excavating Company of Ohio, Inc., was able to install 174 AMERICAN Flow Control American-Darling MK 73 fire hydrants and 280 resilient wedge gate valves in sizes 6 to 18 inches in three months.
Automatic control valves, much like everything else we purchase these days, are not all created equal. Some fall into the high quality bracket with pricing to match, while others hover closer to the lower quality and price sensitive end of the scale. Unfortunately, when evaluating control valve prices, it is not always clear what you are being offered and what standards the valve actually meets. Here are a few questions to consider and ask the supplier to ensure you get years of trouble free operation that lasts longer than it takes the sales person to drive out of your parking lot!
