Water & Energy Savings

Chemstar WATER scours the industry for new technologies to bring the lowest cost, most sustainable, and environmentally-friendly solutions to its customers. At Chemstar WATER we are OEM-agnostic enabling us to find the best technology to provide the right solution to meet the customers’ requirements.

Because the evaporative cooling systems are designed to evaporate water and eventually concentrate minerals in the water, they directly affect the water consumption and water savings of the plant. One of the ways to optimize evaporative cooling systems is to pretreat the incoming make-up water to remove the minerals, especially the divalent ions. That way the water can be recycled, reused more before it reaches a critical mineral concentration that would otherwise produce scale and corrosion. Although it sounds easy, removing minerals from water is anything but. Historically reverse-osmosis has been a good tool for just that. However, it has lower recovery rates that hinder water retention.  In order to overcome the challenge of removing minerals while saving water, Chemstar WATER has jointly developed a new electrodialysis reversal technology, called cross-flow de-ionization, or in short XDI™. With XDI™ we can improve the cycles of concentration of a cooling system significantly reducing the blowdown water amount and achieving significant water savings.

Furthermore, Chemstar WATER can help improve overall energy and carbon footprints by reducing the use of chemicals utilizing on-site, on-demand, chemical generation systems, such as on-site mixed oxidant generators, hypochlorite generators, and many others. These on-site generation systems are not only environmentally friendly but also significantly safer than hazardous chemicals.

Legionella Control

Chemstar WATER has developed and fine-tuned its proven microbiological control program focused on helping mitigate many microbiological challenges. Legionella is no other. We recommend our customers adopt a robust water management program to control microbiological activity, especially Legionella Pneumophila, through effective biofilm control in their cooling and potable water systems.

We use state-of-the-art technologies to detect microbiological activity while partnering with world-renowned infectious disease experts. We know the challenges you face in fighting Legionella, microbiological, biofilm, and fungal activities, and are ready to partner with you in creating a customized solution to mitigate them.


LEGIONELLA IN HUMANS

What is Legionella?

Legionella is a ubiquitous, naturally occurring bacteria found in freshwater sources. While in nature, such as rivers or lake streams, it can be innocuous,  it becomes a health concern when it grows in water distribution systems. Inhaled aerosolized Legionella would lead to severe pneumonia called Legionellosis or Legionnaire’s disease.

History of Legionella's Disease

How it Spreads to Humans

When water storage systems are not properly maintained,  Legionella tends to increase in number in the water supply. Room temperature is the perfect temperature for Legionella to thrive. From there water droplets are aerosolized and then inhaled by humans causing extreme lung infections and inflammation. Outbreaks are more common in large and complex cooling systems as well as potable systems that serve showers like those in hospitals, hotels, and cruise ships. It is less likely that humans get it from person to person transmission or become sick from drinking water containing Legionella.

Symptoms and Complications

Symptoms can come on 2-10 days after exposure. The shortlist includes:

  • fever
  • cough
  • chills
  • or muscle aches

People most at risk are those with weakened immune systems, current or former smokers, have lung conditions, and are over 50. The ensuing complications lead to respiratory failure, septic shock and acute kidney failure.

LEGIONELLA IN THE WATER

Source of Infection

As we noted earlier, this form of bacteria is actually present and often harmless in free-flowing bodies of water and soil. However, because we tend to capture and hold water for drinking and everyday use, residential features like water tanks, showerheads, faucets, pools, and hot tubs, can become potential hotspots for bacteria growth. Fortunately, air conditioners are not a source because they do not rely on water for transmission.

The origin of outbreaks at the commercial level center around the distribution systems of large buildings via their plumbing, humidifiers, mist machines, and cooling towers.

Ripe Conditions

Certain criteria have been found to heighten the growth of Legionella:

  • Sediment build-up: The presence of sludge, scale, and organic matter leads to the creation of a biofilm.
  • Wide temperature ranges: Without adequate biocontrol, Legionella can remain viable even in cool water but flourishes in 68°F to 113°F.
  • Like stagnant zones: Stagnant conditions like those in a water tank reservoir, pipings, fittings, and basins make it hard to eradicate.
  • Grow alongside other microorganisms: The presence of untreated algae or other bacteria and protozoa, which serve as hosts, may lead to the proliferation of Legionella.

Cases on the Rise

Chart of Legionella Cases on the Rise

Legionnaires is serious. It is estimated that about 1 out of 10 people do die from the infection. However, it can be treated with antibiotics. The majority of people who become infected do need hospital care, but they make a full recovery.

 

Mitigation and Prevention

The good news! Outbreaks of Legionnaires’ disease are preventable if the proper water management systems are in place. Buildings must ensure that water is monitored and cleaned regularly.

With greater visibility and education there have been more regulations and guidance.

Boiler Systems

At Chemstar WATER, we design our boiler systems treatment programs to protect the integrity of boilers and all related heat exchange equipment such as economizers, air preheaters, deaerators, superheaters, and steam turbines.

Many leading industrial and government customers have been trusting Chemstar WATER with their large steam boilers for decades. As you will see in one of our case studies, Chemstar WATER delivers outstanding performance when it comes down to scale, deposit, and corrosion control in the boiler systems.

Efficiency Maximization: 

Because boiler systems are energy-intensive and costly, it is in our customers’ best interest to maximize boiler efficiency through increased steam production and reduced fuel consumption in a two-step process:

  1. The first step is to ensure steam and condensate losses are controlled well, which includes treating condensate return.
  2. The second step is minimizing blowdown, which can be achieved by using makeup water pretreatment systems including water filtration and softening systems, demineralizers, dealkalizers, reverse osmosis systems, electrodialysis reversal as well as water treatment chemicals such as polymer organics.

Through these methods, the majority of our customers’ energy savings are more than their annual water treatment costs.

Customized Programs:

The makeup water quality changes and discharge requirements differ depending on the location. That’s why we tailor water treatment programs specifically for each customer. As a result, customers enjoy the following benefits:

  • lowest optimum boiler blowdown resulting in water and associated energy savings
  • extended life of boiler tubes
  • 24/7 remote monitoring of the key indicators with control ranges
  • improved plant uptime by eradicating scale and corrosion-related downtimes
  • regular reporting of key indicators and suggested proactive measures

COOLING WATER SYSTEMS

Over the last two decades, Chemstar WATER has developed, fine-tuned, and proven its cooling systems water treatment program’s ability to effectively mitigate microbiological activity. We have seen the difference a strategic and proactive approach makes. Thus we recommend our customers adopt a robust water management program to control microbiological activity, especially Legionella Pneumophila, through effective biofilm control.

We use state-of-the-art technologies to detect microbiological activity, such as inline adenosine triphosphate (ATP) monitors, proprietary quantitative polymerase chain reaction (qPCR) testing systems as well as leveraging our partnerships with reputable laboratories.

Our programs are designed to control mild-steel and copper corrosion, mineral scale deposits, biofilm growth, and system fouling. Our cooling-systems water treatment formulations are environmentally friendly and meet the most stringent discharge guidelines.

Chemstar WATER has also proven itself in extending the life of direct and indirect evaporative cooling systems, adiabatic cooling systems, heat exchangers, and once-thru cooling systems including ocean make-up intakes as well as process equipment.

Evaporative cooling systems directly affect the water consumption and usage effectiveness of a plant. One way to optimize cooling systems is to pretreat incoming make-up water to remove divalent ions. Due to the lower recovery rates, such systems make improvements limited. Chemstar WATER has jointly developed an electrodialysis reversal-based system to improve the cycles on the concentration of a cooling tower by pretreating the make-up and recovering the cooling tower blowdown, achieving significant water savings.

We tailor water treatment programs specific for each customer. This enables us to achieve peace of mind for our customers through:

  • microbiological control
  • high cycles of concentration
  • low corrosion and scale formation
  • 24/7 remote monitoring of the key indicators with control ranges
  • improved plant uptime by eradicating scale and corrosion-related downtimes
  • regular reporting of key indicators and suggested proactive measures

Influent Water Treatment

Treating incoming water to the facility is a key first step to minimize the microbial contamination downstream. Chemstar WATER has been a trusted provider for secondary potable disinfection systems for many commercial and residential buildings.

Although each customer’s water treatment requirements are different, generally we believe treating the plant make-up water upfront is more effective than treating the water chemically when it is in the boiler and cooling systems. With this approach, we believe that our customers can achieve the lowest cost of operation in the long run.

Chemstar WATER prides itself on utilizing the latest cutting-edge technology from the industry when solving our customers’ water treatment challenges. In the case of feed water treatment, we utilize a wide variety of technologies such as water filtration and softening systems, demineralizers, dealkalizers, reverse osmosis, electrodialysis reversal, electro deionization, and electrolysis processes.
