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. It then becomes a pervasive problem within the entire leachate network in the landfill.

Other alternatives include commodity acids — for example, commodity grade and concentrated sulfuric acid. But 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 any associated landfills) 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.

Goodway’s Coverage of The AHR 2017 Expo

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.

Buying a Coil Cleaning System? Avoid these Five Mistakes

coil cleaning systemsSummer is coming, and with it a huge uptick in your facility’s HVAC usage. If your cooling systems aren’t properly serviced and maintained both your facility and your boss may be heating up fairly soon. Want to stay cool, optimize efficiency and still keep costs down? Avoid these five mistakes when buying an enterprise-grade coil cleaning system.

1 – Buying Same-Old System

As noted by AHCR News, coils have undergone significant evolution as companies look for ways to reduce refrigerant use without a loss of cooling power. Advances such as MicroGroove and micro channel technology, for example, leverage smaller-diameter copper tubes to carry less refrigerant at higher pressures. The result? Old cleaning tools may not have the ideal combination of pressure and flow to properly maintain new coils — for example, pump sprays may provide basic surface scrubbing but aren’t powerful enough to penetrate new coil beds. Bottom line? If you’re running new coils, you need new cleaning tools.

2 – Buying One-Size-Fits-All System

Another common mistake? Using generic tools rather than specific coil cleaning solutions. While “one size fits all” solutions may offer a quick clean they’re not designed for regularly scheduled, long-term cleaning. Look for industry-standard solutions — such as Goodway’s CoilPro line — which are tailored to meet specific cleaning needs.

Coil Cleaner Market Trends: Mastering Preventive Maintenance Brings New Business

Dirt is a fact of life. Soil, pollen, dust and other debris conspire to make any HVAC installation less efficient over time; the nature of air and moisture transfer between condensing and evaporating systems make dirty coils an inevitable consequence of running HVAC. As noted by Contracting Business, however, a little dirt goes a long way when it comes to device operating costs and lifespans. What’s more, new markets are opening for companies able to guarantee clean coils and timely maintenance.

Cheap Natural Gas Fires Up Cogeneration Plant Proponents

In 2006, Koda Energy inked a deal with Minnesota company Rahr Malting Co. to build a power plant that not only generates electricity but captures waste heat created during the process and puts it to use.

iStock_000039111840SmallThese “cogeneration” plants aim for both environmental stewardship and fuel savings, which fluctuate with the price of natural gas.

When the plant got the green light, for example, the price of natural gas was $13 per one million BTU. By 2012, it bottomed out at $2. Is cheap natural gas the start of a slow decline for cogeneration?

Up in Arms: Legionella Found in Unlikely Places

In 1976, Legionnaires at the Pennsylvania America Legion convention in Philadelphia started to get sick. At first, symptoms seemed identical to those of a typical pneumonia-based lung infection but the disease spread rapidly; over 200 people became ill and several died.

iStock_000043111880SmallThe outbreak prompted the discovery of Legionella, a water-loving and lung-hating bacteria. Mist from contaminated water – possible when showering, using hot tubs or even after prolonged exposure to air conditioning – causes this infection, which results in high fever, hacking cough and muscle aches.
