Dolphin WaterCare has been providing environmentally responsible water treatment solutions for over a decade. Our state-of-the-art, patented technology, known as The Dolphin, is installed in facilities throughout the World with over 5,000 systems installed to date. Our organization is dedicated to treating water responsibly. We are focused exclusively on water technology and creating technology, products and services that support water and energy savings.

Dolphin WaterCare is a proven, reliable and chemical-free process to treat the waters of:

• Cooling Towers
• HVAC and Process Chillers
• Ammonia Condensers 
• Process Heat Exchangers 
• Fluid Coolers
• Hot Water Systems

The origin of the Dolphin WaterCare technology was born out of a belief that "green principles" can be applied to nearly all aspects of our modern world. Early commercialization of the Dolphin technology took place at University of Connecticut with the company's founders exploring sustainable strategies and long before it was a common practice. In 1994, the first Dolphin chemical-free prototype was installed (and is still operating!) and the search for funding began.

Clearwater Systems Corporation was formed and in April of 1998 the first commercial Dolphin 1000 model was shipped, which controlled all three of the major water treatment responsibilities- biological life, scale and corrosion. The Dolphin 2000 model followed in 2002, which enhanced biological control by a factor of 10. In 2006, the Dolphin 3000 model was offered commercially, which increased biological control by an additional four times and included many operational enhancements. Many third party studies were accomplished during this time and the credibility of Dolphin WaterCare was secured and the company was poised to transform an entire industry!

In 2011, Anupam Bhargava was appointed CEO and set a mission for the company: transform the water treatment industry by evolving Dolphin WaterCare into a truly viable and sustainable alternative to traditional chemical water treatment. Key to this mission was the creation and launch in 2012 of Dolphin WaterCare's in-house water treatment service organization made up of skilled, experienced experts in the areas of both HVAC and water treatment. Also in 2012, Dolphin WaterCare shipped its 5,000th system, completed its 300th LEED™ point-qualifying installation for customer's green building projects and secured its 22nd patent.

Today, Dolphin WaterCare is sold around the globe through our Reps and Partners in North America, Europe, Australia, Russia, Southeast Asia and selected areas of China and the Arabian Peninsula. With the growing need for sustainable water strategies and an increasing awareness of the vast amounts of water consumed every day in commercial buildings Dolphin WaterCare is providing companies around the world with world-class water treatment and reduced operating expenses - and, changing an industry for the better!

How the Dolphin Technology Works

The Dolphin system leverages pulse-power technology to impart a broad spectrum of electro-magnetic fields into the flowing cooling tower water. This removes the static charge from naturally-occurring particles and results in:

• Scale Prevention: With the static charge removed the particles then become the preferred surface for minerals to precipitate around rather than forming scale on the surfaces of the cooling tower and HVAC equipment

• Corrosion Control: The system operates in a saturated environment which is naturally non-corrosive.  Additionally, there is no risk of chemical corrosion

• Biological Control: Superior biological control is achieved through encapsulation and electroporation.  Dolphin treated water typically has even lower biological counts than the accepted standards for drinking water

Scale Prevention

Water based evaporative cooling systems reject heat by evaporation of water. This process occurs within a cooling tower.  Water exits the cooling tower as a vapor leaving behind the naturally occurring dissolved minerals present in the water. Concentration of dissolved minerals increases over time. Upon sufficient concentration, dissolved minerals such as calcium carbonate (i.e., limestone) become solid in a process known as precipitation. The Dolphin changes the form of precipitated solids from hard lime scale found on equipment surfaces to a harmless powder flowing with the cooling water.

The Dolphin System accomplishes this change by “activating” naturally occurring, small-suspended particles in the water. Small suspended particles exist in large quantities in all city water or well water that is used as a source of make-up water to a cooling tower. Under Dolphin System treatment, suspended particles (suspended meaning that they neither sink nor float because of their small size) act as seeds for precipitation of dissolved minerals. The Dolphin System’s pulsed fields activate the suspended particles by removing their naturally present static electric surface charge. Once the surface charge is removed, precipitation of dissolved solids occurs preferentially around the “activated” particles rather than on equipment surfaces. The resultant product of this process takes on a powdery appearance and character and is called “Dolphin powder”.

Provided sufficient concentration of dissolved minerals is maintained Dolphin powder, consisting mainly of calcium carbonate, will continue to grow either by coating or adhering to the suspended seed particles. These coated particles or powder can be easily removed from a cooling tower basin by manual means, filtration, or centrifugal separation. The concentration of Dolphin Powder is typically about 15% of normal blown-in dirt in a cooling tower.

Corrosion Control

In the aerated water flow of cooling systems metals used in the construction of these systems will naturally corrode. Inhibiting the rate at which these metals corrode is an objective of any water treatment program. Corrosion inhibition with the Dolphin System is achieved by formation of cooling water chemistry where calcium carbonate is concentrated sufficiently for precipitation to take place. This water chemistry (i.e. saturated with calcium carbonate) creates a benign corrosion environment for the materials of construction associated with cooling systems. Water chemistry control is obtained by use of a conductivity control device.  Conductivity controllers are commonly used in water based evaporative cooling systems. The combination of saturated water chemistry established by conductivity control and freedom from equipment scale by use of the Dolphin System provides effective corrosion inhibition without the need for chemical additives.

The Dolphin prevents the source of other corrosion attacks, such as microbial influenced corrosion arising from formation of biofilms and under deposit corrosion caused from formation of permeable or semi-permeable deposits on equipment surfaces. Under Dolphin System treatment, these conditions are absent and therefore these sources of corrosion are eliminated.
