Ice may look simple, but it is a complex material. Small changes in water chemistry can significantly affect how it freezes, its strength, and its response to pressure [8]. Research from Toronto Metropolitan University's Jet Ice Research Chair shows how minerals, gases, and impurities can become trapped during freezing—directly affecting ice clarity, strength, and friction [8].
Ideal TDS for hockey ice [2]
TDS reduction equals temperature effect [2]
Ideal humidity range [1]
A landmark 2026 study in Sports Engineering examined how water quality affects ice hardness and skate-to-ice friction under controlled rink conditions. The results showed that temperature influences ice hardness and static friction, with colder ice being harder and exhibiting higher static friction. Critically, water quality plays an equivalent role: lower total dissolved solid (TDS) levels reduce static friction, with effects comparable to a 1°C increase in ice temperature [2].
The study found that ultra-pure water produced softer ice, while moderate TDS levels (80-100 ppm) maintained ice hardness with only minor friction increases. These findings support hockey rink recommendations to maintain TDS near 80 to 100 ppm to balance ice hardness with friction performance [2].
Don Moffatt, five-time Olympic ice master, explains: "Our main concern is pH, but our main measurement is called TDS, total dissolved solids. Too many, and the ice clouds over and blurs the lines and logos. Too few, and the sheet won't bond; it breaks apart. The sweet spot is between 75 and 125. That gives us a nice, dense sheet of ice." [5]
According to the Canadian Water Quality Association, critical water quality parameters for ice include [8]:
High TDS levels, often from calcium, magnesium, or iron, can trap impurities in the ice. This leads to cloudy ice and weakens its surface [8].
Hard fill water affects how ice bonds and reacts to temperature changes. Conditioning helps keep ice consistent throughout games [8].
pH influences carbonate equilibria and ice crystal formation. Stable pH is essential for consistent ice quality [2].
Dissolved gases (oxygen and carbon dioxide) can form microbubbles, reducing strength and affecting resurfacing quality [8].
Low particulates and dissolved gases cut down bubbles and weak spots, boosting puck bounce and reducing chipping [8].
Organic carbon contributes to TDS and can affect ice clarity and bacterial growth in resurfacer systems.
A study of 55 North American ice arena managers confirmed that water quality plays a critical role in ice management, yet conflicting recommendations highlight the need for further research to determine optimal TDS levels [1][4].
Different sports demand different ice characteristics—and water quality plays a role in achieving each [8]:
Ice temp: -6.2°C average [4]
TDS target: 80-100 ppm [2]
Moderate TDS for better hardness
Low particulates and dissolved gases
Controlled hardness and pH [8]
Ice temp: -5.2°C average [4]
"Softer" ice for landing cushion
Reduced bubbles and inclusions
Improved visual clarity [8]
Ice temp: -4.6°C average [4]
Very low TDS for pebbling
Controlled pH and hardness
Minimal gases and particulates [8]
Dense, uniform ice
Low but controlled friction
Tight thermal control [8]
The International Ice Hockey Federation (IIHF) recommends maintaining TDS levels below 120 ppm, while many NHL ice-makers prefer the narrower range of 80–100 ppm for desirable ice conditions [2]. World Curling endorses the use of reverse osmosis water, which typically contains less than 10 ppm TDS [2].
Most ice rinks manage water quality through chemical treatment or water softeners—but these approaches have significant drawbacks that affect ice quality and operational costs.
Traditional Chemical Treatment
Alters water chemistry: Removes calcium and magnesium, adds sodium
Sodium affects ice: Changes friction and hardness characteristics
Ongoing chemical costs: Salt, resin replacement, maintenance
Brine discharge: Environmental concerns [7]
Scale still forms: Softeners don't prevent scale in equipment
Water waste: Regeneration cycles waste 20-100 gallons daily
"Cities are banning these systems due to environmental impact." [7]
Vulcan Chemical-Free Solution
Preserves ideal TDS: Maintains 80-100 ppm target range
No sodium added: Ice chemistry unchanged
Zero ongoing costs: One-time investment
Zero discharge: Environmentally friendly
Scale prevented: Protects ice resurfacers, water heaters, pipes
Zero water waste: No regeneration required
How It Works:
Vulcan's physical impulse technology alters the crystalline structure of calcium carbonate so it cannot bond to surfaces. Minerals stay in the water—preserving the precise TDS levels you need—but don't form scale in your equipment [6].
Chemical softeners alter your water chemistry—making it harder to achieve the precise TDS levels required for optimal ice. Vulcan preserves your target TDS while preventing scale. You get the ice you want without the chemical costs.
ENERGY EFFICIENCY CASE STUDY
Facility: Sportsworld Arena, Kitchener, Ontario
Duration: May 2024 – May 2025 [3]
Water heated up to 60°C is typically used because it gets the air out of the water for a smoother surface, both for making and resurfacing arena ice. Sportsworld Arena had consistently the highest energy intensity per square foot across municipally owned arenas in the region of Waterloo [3].
$6,255 in savings in first year [3]
3.5-year payback period
$134,482 projected 25-year savings
14 tonnes CO₂ equivalent emissions avoided
Ice quality and user experience maintained [3]
"During hockey tournaments ice may need to be resurfaced as many as 30 times in one day—with only one flood using up to 500 L of water." [3]
Kitchener achieved savings through cold water deaeration. Now imagine combining that with Vulcan scale prevention:
Protect the deaerator unit from scale
Keep water lines at full diameter for optimal flow
Prevent scale in ice resurfacers
Compound energy savings year after year
ENERGY RETROFIT CASE STUDY
Facility: Fenlands Recreation Centre
Location: Banff, Alberta
System: Two hockey arenas [9]
Installation of a REALice system—an energy-saving water treatment system for ice rinks that creates a controlled vortex as water flows through it, eliminating the need to use heated water when building or resurfacing ice [9].
44,785 kWh/year electrical energy savings [9]
270 GJ/year natural gas energy savings
39 tonnes CO₂e/year GHG reductions
$25,227 rebate/incentive
"This project represents one of the many ways the Town of Banff is working to reduce our overall energy consumption, which is a key strategy in addressing climate change." — Karen Sorensen, Mayor [9]
Banff achieved significant energy savings through cold water technology. Vulcan would protect that investment by:
Preventing scale in the vortex system
Keeping pipes at design diameter
Protecting ice resurfacers from scale buildup
Ensuring consistent water quality for optimal ice
WATER QUALITY CASE STUDY
Facility: UC Davis Bodega Marine Laboratory
Location: California
This leading research facility faced severe scale buildup in their water heating system, causing frequent maintenance and energy waste [10].

No scale-related maintenance in 3+ years
Energy savings validated in facility audit
The same scale that plagued UC Davis's water heaters attacks ice rink equipment—water heaters, boilers, ice resurfacers, and pipes. Vulcan's proven technology protects them all.
Recent research highlights growing environmental concerns in ice rinks [1][4]:
A study found that a typical ice hockey game can produce up to 20 grams of microplastics, primarily from players' equipment and the boards. These microplastics can end up in ice resurfacing wastewater, potentially entering local water systems [4].
PFAS (per- and polyfluoroalkyl substances) have been detected in ski area snowmelt and surrounding soils. As arenas focus on both performance and sustainability, addressing these contaminants will become increasingly important [1].
The City of Nový Bydžov in the Czech Republic is researching the use of captured rainwater as an alternative source of process water for ice rinks, potentially saving drinking water resources [6].
Vulcan's chemical-free scale prevention works with any water source—municipal, treated, or rainwater. No chemicals, no discharge, no environmental footprint.
