Why Removing Calcite (Limestone) from Landfill Leachate Systems’ Lines Require Specialized Descaling Chemicals
Calcite clogging is a major problem in the industry. This type of scale is typically associated with pipes, heat exchangers or other water handling equipment in general industry but it is also true that landfill channels can also become completely clogged with limescale. Typically the problem is ignored in landfills until it is too late and leachate channel systems become clogged resulting in back-ups of leachate flow. Ignoring the problem when signs of clogging are starting to happen only creates bigger headaches down the road.
When it comes to cleaning calcite deposits in your leachate lines, there’s no better option than an industrial strength, specialized chemical descaler. According to Goodway’s Director of Liquid Solutions, Ray Field, “It’s well documented that an inhibited acid descaler is the product of choice in these cases.” The main advantage to a chemical descaler is its ability to permeate throughout the entire leachate collection piping system. Alternatives like high-pressure water jetting may reach inside the first 75 feet of piping, but after that the scale down the channel is so deep that water jetting can’t get to the worst areas of scale and becomes a pervasive problem within the entire leachate network in the landfill.
Other alternatives often employed are the use of commodity acids, for example, commodity grade & concentrated sulfuric acid. This can make a limescale headache even bigger. When adding sulfuric acid to calcite-clogged pipes, you’re going to end up turning your leachate lines into gypsum (or calcium sulfate). That’s a million times worse than even the worst limescale problem!
Power plants, and landfills hat may be associated with them, provide an additional challenge. Each involve massive amounts of water. What’s more, they share a symbiotic relationship with regard to methane gas. Power plants pay landfills for their methane gas. When their leachate lines become clogged, methane metering from the landfill slowly chokes off — along with the amount of revenue going to the landfill from the power plant. That’s a direct result of letting calcium carbonate build up and going unchecked in a landfill leachate collection system.
Certain chemical descalers are not only safe, but also dissolve mineral deposits extremely fast. For example, Goodway’s Scalebreak Liquid Descaler is biodegradable and dissolves calcium, lime, rust and other deposits from your systems. This particular descaler can be applied in a variety of environments that contain different materials, including steel, brass, copper, plastic and rubber. Thanks to Goodway’s customizable capabilities, Scalebreak products include special formulas specifically for stainless steel, maritime applications and potable water systems. Goodway also offers alkaline neutralizing crystals which allows lowering descaling acidity to meet your needs.
Not only will specialized chemical descalers make systems operate more efficiently in the here and now, they will also increase the overall life of your systems with efficient and non-interrupted operation.
In the end, removing calcite from leachate lines requires customizable chemical liquid solutions for descaling — and maybe an aspirin or two if you’ve put it off for a while.

Yes, the facility management industry has entered the age of ‘big data’ where extremely large data sets are being collected and analyzed to reveal patterns, trends, and associations, primarily between HVAC equipment and energy optimization.
However, “Big Data” may be the most worn out catchphrase ever. When you think “big” you think Wall Street, the Pentagon, Silicon Valley. Places far and away from where you live and work, with needs far different from what you encounter in systems management. And is there any word less exciting than “data?” But unlike in other industries, the HVAC industry seems to realize big data is driven by small data and small data is still king. Without small data, big data is useless.
Martin Lindstrom recently wrote a book with a simple premise: sweat the small stuff. Big data, says Lindstrom, extrapolates correlations between small data. Small data, however, provides the why and HVAC facility technicians are already masters of small data. You deal with it every day. Your life revolves around minute differences of 1 and 2 percent that translate into massive differences for your boss or client. Those facilities gauges and monitoring systems are a treasure trove of small data. And small data is what you rely upon on a day-to-day basis. While big data has a lot to offer regarding big, sweeping decisions on energy policy at the very top, small data helps you to troubleshoot and make improvements at the micro level. Those small changes can mean big differences in terms of system performance.
The difficulty with spending your day at the small data level is that you’re often tasked with inputting that data yourself, and there’s quite a bit to track. Think of all of the maintenance log data you’ve scribbled on paper. Now, additional time must go into comparing that data to past logs. Consider that you can’t immediately get feedback on the implications of your latest reading so you’ll have to pause and eventually restart your thought processes. LogCheck reduces this pain and provides you insights from your small data right in the field. By entering routine inspection data into their mobile app rather than paper, you get instant feedback while you’re still in front of your equipment as well as an online dashboard for deeper analysis.
Goodway’s VS-S Video Borescope and VS-W Borescope, are also great tools for getting the small data you need to keep your facilities running. These borescopes are primarily used for inspecting inside tubes. To focus in on the tube’s walls and blockages, each scope’s field of vision is quite small. They are used to visually identify issues before cleaning and gather photographic evidence after cleaning to help assess quality.
Most everyone can agree that Big Data is the likely future in facility maintenance. But Big Data’s power comes mostly in making big decisions. The day is coming, sooner rather than later, when your chillers will tell you what they need. Until then, you’ll need to continue to figure out the small stuff, and we’ll keep trying to make it as pain free as possible.
Unmanned aerial vehicles, commonly called “drones,” are coming into their own in facility maintenance. Facility managers employ drones to inspect areas difficult or dangerous to monitor, including HVAC systems. No longer the exclusive domain of hobbyists and the military-intelligence community, drones are poised to revolutionize the way America does business.
Consider drones also being deployed to inspect difficult and dangerous areas like rooftops for HVAC maintenance. Using a drone to survey a rooftop allows you to fully understand a maintenance or cleaning need before sending a technician up, drastically reducing his time spent in a dangerous situation. Even with scaffolding and safety harnesses, he’s taking on risk. A drone, however, takes virtually no risk. You might lose the drone, but drones are comparatively inexpensive and prices keep dropping.

Drones possess benefits far beyond safety, however. They reduce maintenance costs significantly, collecting data faster than any human can. That’s not just money saved in man hours. It’s also money saved through getting equipment back online sooner rather than later. High definition video, recorded via drone, allows facilities managers and maintenance engineers the opportunity to examine potential problems and discuss solutions from the safety and comfort of their offices.
And you can say goodbye to your clipboard. Drones collect data, then send it off for storage in the cloud. Once uploaded, facility management software makes sure maintenance requests don’t get filed away in the “pay no mind” file. Your facility management software will send an alert to the relevant maintenance technician. You then have a record of that alert, increasing both efficiency and accountability.
The footage your buddy took after he strapped a GoPro to a drone is just the tip of the iceberg. Drone applications over the next year will make day-to-day maintenance safer, easier and more cost effective. Perhaps most importantly, drones and related technology will make sure maintenance gets done. That’s an overall increase in your company’s efficiency. And that means more money to reinvest. With the cost of drones plummeting, don’t get left behind as this revolutionary new technology reshapes American industry.

The AHR Expo is a massive trade show where every year, thousands of industry insiders, manufacturers and distributors converge on a Convention Center to show off the latest and greatest in the world of HVACR. This year’s Las Vegas event is particularly exciting, with new technologies such as split cassette systems from @Samsung, VRF systems and Internet of Things-enabled technologies promising to revolutionize the field.
Samsung’s development sparked interest due to its aesthetic appeal. The HVACR industry is starting to design its products not just from the perspective of what works best, but also what customers will want to look at, year in and year out. New VRF systems mean lower costs, but also less wear and tear on the system in general. @Rinnai America debuted a tankless system with 96 percent thermal efficiency. Some companies, such as @JohnsManville even used technology to display old wares, like their tower showing differences in sound attenuation.
And, of course, there’s the Internet of Things. Smart thermostats are just the beginning. @BellGossett updated its intelligent pump and variable frequency drive. On-site setup and configuration is estimated to have been cut in half by this updated pump. @Victaulic debuted the world’s first grooved, installation-ready copper fittings. One subject that continues to be left out of the innovation conversation, however, is maintenance.
Maintenance is often an afterthought in the world of HVACR, despite the fact that companies might be losing hundreds of thousands or even millions of dollars in a year due to poorly running machines. Maintenance relates directly to efficiency and efficiency is synonymous with profitability in the field of HVACR. Take for example, microchannel coils. These coils are frequently cleaned using caustic hydroxides, which corrode and dissolve the aluminum within the coils. Improperly maintained machines means a shorter lifespan for basic equipment, higher cost of ownership and lower efficiency over the life of the cooler.
In fact, efficiency, tightly tied to maintenance is one of the strongest indicators of profitability. The investment, facility management and maintenance side of HVACR is aware of this. The manufacturing sector, however, seems less interested.
Goodway is proud to own innovation in the field of HVACR maintenance. We remain keyed into the industry, looking not only for new ways to clean equipment, but also constantly improving the mechanical and chemical solutions used. This means lower cost of ownership, less downtime and increased efficiency. Maintenance might not be the most exciting area of the HVACR world, but @GoodwayMachines is working hard ensuring maintenance doesn’t get left behind as HVACR becomes increasingly high tech.
In the average building, chillers account for between 35 and 50 percent of energy expenditures. Even minor adjustments in chiller efficiency can significantly lower the overall overhead of your business. Chiller efficiency and its relationship to the Internet of Things will be on everyone’s mind this weekend at the AHR Expo 2017 in Las Vegas, NV.
Magnetic bearing chillers are a quantum leap in chiller technology. They can save a single business $4 million over the life of the chiller in energy costs. These new chillers don’t require oil, or mechanical seals and gears. This ensures a far longer lifespan. At the same time, it can dramatically increase efficiency of the chiller. The U.S. Naval Facility in Newport, Rhode Island saw an energy savings of 65 percent when switching over to these new chillers. What’s more, you don’t have to change out the gaskets, bearings or seals. In terms of total cost of ownership and downtime, magnetic bearing chillers are far superior even to the chillers being producers 10-15 years ago.
Fortunately, it’s not necessary to reinvent the wheel to increase the efficiency of your chillers. The Internet of Things automates efficiency with very little upfront cost. Daikin has just released two chillers (one scroll, one screw) capable of natively monitoring energy consumption at the equipment level. This provides facility managers with a robust, streamlined solution to reduce overall energy costs without any headaches.
In fact, 2017 is set to be the year of the smart building. Internet of Things-enabled chillers will play a vital role in keeping building maintenance costs down and reducing environmental impact without skimping on keeping the building cool. What’s more, IoT-enabled chillers take the burden of scheduling maintenance off of the facilities manager. In some cases, the chillers will be able to order their own replacement parts and maintenance equipment before you even know there’s a problem. When off-site maintenance crews show up, they won’t need you to tell them what’s wrong with the chiller. They’ll already have a host of metrics to help them make the right repairs, helping to save you money on man hours and reduce downtime.
While the Internet of Things will provide significant improvements in efficiency, those won’t matter much with dirty chiller tubes. The RAM-PRO-XL Contractor simultaneously cleans your chiller tubes while preventing corrosion after cleaning. You know how quickly your tubes can start oxidizing and corroding during cleaning. The RAM-PRO-XL Contractor Chiller Tube Cleaner’s TubeGuard system makes sure that won’t happen. The tablet-based system uses biodegradable cleaners without sacrificing anything in the way of power.
Combine the latest advancements in connected technology with robust maintenance tools for optimum performance in your chillers. And if you happen to be attending the AHR Expo this year, make sure to check out our exhibit at Central Hall – C4328.
