Microbiological Control in Cooling Towers
From the water treatment industry’s perspective, the practice of controlling the proliferation of microbial fouling in HVAC/Industrial cooling water systems has traditionally been focused on keeping algae, slime and fungus in check. Without proper control, organisms will colonize, grow, and turn into biomass and biofilm. Displaced biomass can lead to restrictions in flow, loss of heat transfer and other serious water-borne problems. In addition, a longer-term challenge is that accumulated bacterial slimes (biofilm) will lead...

Boiler Re-tubing: On Site Work
Below are pictures of a recent boiler tube replacement in Brooklyn. During this project we Torched and cut 25 old, corroded bottom boiler tubes (picture 1). Once cut, these tubes are removed from the boiler and the boiler room itself. The boiler vessel and tube drum are then flushed clean. Twenty five new U.S steel boiler tubes are then installed and rolled tight for a proper seal with the front and back tube sheets (picture...

Softener Operation and Regeneration
Softener Operation A sodium zeolite softener operates through two basis cycles: the service cycle, which produces soft water, and the regeneration cycle, which restores the exhausted resin to capacity. During the service cycle, raw water enters the softener through the inlet distributor, flows through the resin bed, is collected by the underdrain system and then transferred to the point of use. When a softener is exhausted, it must be regenerated. A number of methods may...

Principles of Zeolite Softening
Principles of Zeolite Softening Sodium zeolite softeners use exchange resins made of polystyrene. These resins have sodium ions loosely attached and will readily give up sodium for more desirable ions such as calcium and magnesium. This exchange is only for cations (positively charged ions). This is why sodium zeolite resin is referred to as a cation exchange resin (Figure 2). Figure 2 – Sodium zeolite resin gives up sodium ions for calcium and magnesium...

Softener Application and Ion Exchange
Softener Application The potential for scale and deposit buildup exists in every raw water supply. The ability of the sodium zeolite softener to reduce this potential effectively and economically makes this an ideal pretreatment for boiler feedwater and many types of chemical process waters. Compared to other softening methods, sodium zeolite units offer many advantages: The treated water has a very low scaling tendency because this method reduces the hardness level of most water supplies...

Softener Operation and Troubleshooting
Good water softener operation is often a key factor in efficient boiler system performance. In its simplest terms, softening is the removal of naturally occurring scale-forming ions that are present in all water irrespective of its source. Although we take it for granted, the operation of a water softener is really a remarkable phenomenon. As you can see in the example below – a properly functioning can, in fact, remove thousands of pounds of potentially...

Cold Crystallization
One of the key objectives of effective cooling water management is to prevent the precipitation of scale-forming minerals onto heat transfer surfaces. Scaling potential is highest at the hottest metal surfaces, and where the transfer of heat occurs from a process into the cooling water “ across plate/frame or shell and tube exchangers. However, it is also possible for scaling to occur at the other end of the process where heat is removed. Since cooling...

Heat Flux and Boiling Regimes: Part 3
In an ideal world, all the waterside metal surfaces inside your steam boiler would be exactly 86°F / 30°C above the boiling point when the burner is firing. This would result in perfect boiling everywhere throughout your boiler, maximizing the operating efficiency. While this isn’t fully achievable in the real world, the manufacturer typically designs the boiler for Region I / II operation by providing at least 5 ft2 of heat transfer surface area per...

Heat Flux and Boiling Regimes: Part 2
What’s really interesting is that if you were to crank up the burner to 11 at Step 5 and allow the surface temperature of the bottom of the pot to continue increasing, the heat flux through the bottom of the pan absolutely falls off the cliff. That’s peculiar… despite the fact we’ve added more heat, the heat transfer has dropped – how could this be? In this scenario, the water at the bottom of the...

Keep the Water Flowing
Keep the Water Flowing. This statement represents one of those basic rules of thumb in managing any water system. Lack of flow can lead to wide-spread system problems with microbial fouling, corrosion and even fouling from sediment. Without flow and turbulence, water systems will accumulate dissolved gases, suspended sediment will separate from bulk waters, and at the right temperatures biological/organic fouling will be initiated. Chemical inhibitors cannot do the appropriate job of passivating metal unless...

Heat Flux and the Boiling Regimes: Part 1
By Luke Wonnell Besides being a wicked awesome band name, the title of this article refers to some 201 level Thermodynamic principles that have a significant impact on the performance of your steam boiler. “Heat flux” defines how much heat transfer occurs through a given material’s surface area and is expressed in (Btu/hr-in2 or W/m2). Think of the bottom of a pot as the given surface area… the heat flux simply defines how many Btu’s/hr...

Wait… Water has a 2nd Liquid State?
By Luke Wonnell If you’re like me then you remember learning in High School chemistry or pre-req college courses that water has 3 states: solid, liquid and gas right? Water becomes solid ice below 32⁰F, exists as a liquid between 33⁰F and 212⁰F and starts to boil off to a gas at 212⁰F. While these critical points remain, it turns out the liquid state may be a lot more complex than we originally thought. A...

What Exactly is a British Thermal Unit (BTU)?
What Exactly is a British Thermal Unit (BTU)? By Luke Wonnell Oh the Imperial system… home to such gems as hectares, stones, bushels and pints. Personally I’m a fan of that last one, especially when served cold. The Imperial system is very finicky: 12 inches to a foot, water freezes at 32⁰F, boils at 212⁰F, and the water used to fill a pint glass weighs 1.08lbs. Meanwhile the metric system is so neat and tidy:...

Biofilm Control
Presence of the Legionella organism in water systems can often be associated with the presence of biofilm. Biofilm is a sticky substance which forms under the right conditions, often appearing as slime. It attaches to piping and component surfaces, and provides the ideal environment for a community of organisms, including Legionella, to live and thrive. Therefore, controlling biofilm is an integral part of controlling Legionella, and its removal is essential to achieving a proper state...

Reduce Energy Costs with Water Treatment
How does Water Treatment result in Energy Savings for my Building? The primary functions of a Chemical Water Treatment program for heating and cooling systems that use water as a heat transfer medium are the control of scale, corrosion and micro organisms. Left untreated, water will cause scale or mineral deposits to form on heat transfer surfaces, thereby reducing efficiency and increasing energy costs. Exposed to untreated water, metal is subject to corrosion. The corrosion...
