The truth about salt water sanitizing pools and spas begins with disinfection. Chlorine pools and spas disinfect the water by ridding the water of germs, salt water pools and spas create chlorine to do the exact same job.

All salt water pools and spas require two things, approximately 3,500 parts per million (upfront cost to purchase and distribute 300 pounds) salt per 1,000 gallons of actual salt floating around in the water (you can taste the salt). The other is a “Salt Chlorine Generator” (requires electricity) to convert particles of salt into chlorine in order to sanitize the water. You will not pour or sprinkle raw chlorine into the pool because when the pump is running chlorine is produced and added to the water.

The sanitation methods mentioned above have reported negative side effects for people, are harmful to the environment and costly to maintain.

Remember, the job of chlorine to sanitize your water takes place inside the chamber of the HDC device.

About Hydrodynamic Cavitation (HDC)

Hydrodynamic Cavitation (HDC) has been researched and studied for many years and is presently in use worldwide, mostly in wastewater treatment facilities. HDC results have been far more effective than any other water sanitation and purification systems used today. The natural phenomenon of Hydrodynamic Cavitation helps to sanitize the water through the heat signature it creates inside the device, dismantling many toxic pathogens and microorganisms passing through its chamber. HDC dismantles these unwanted items in the water by removing the hydrogen and/or oxygen atoms attached to and making up the molecule – therefore, said molecule no longer exists. HDC also changes the molecular structure of the water into a “restructured” negatively ionic charged body of water, when used as directed. With the waters transformed, the HDC device helps to naturally reduce the need for chlorine and other harmful chemicals in any body of water. It provides a natural ‘trifecta’ outcome that helps to sanitize, purify, and balance the water chemistry on any body of water it is installed on.

Oxidation Reduction Potential (ORP)

The HDC device, when used as directed, creates an increase in the measurable level of ORP (Oxidation Reduction Potential) of the water. ORP is a term used frequently in the water treatment & food processing industry and is measured in + – mv. The best definition of “ORP” is that the higher the ORP in a body of water indicates an increase of the water’s ability to break down contaminants on its own.

That “Chlorine Smell”

The “chlorine smell” that you smell when approaching indoor pools and spas is not chlorine at all. It is called “chloramines” and they are the byproduct of chlorine doing its job to destroy impurities in the water. The HDC destroys the impurities in the water without the use of as much chlorine therefore the smell is reduced or eliminated. Chloramines have been linked to many health issues including lung issues for years. When you use the HDC Products device in your home or business you will enjoy cleaner and safer water for your whole family!

A Story About “Restructured Water”

I have a 26-foot cabin cruiser boat that is slipped in Honolulu Harbor with a 20-gallon fresh water holding tank. I have had it for years and I often take the boat to the outer Islands (36 Miles) to guide canoe paddlers and open water swimmers. When I would fill my tank with shore water, it would go bad in 3 to 4 days. 6 months ago, I decided to take water from my swimming pool that has the HDC Water Filtration Device on it (the pool has never been better with nearly 0 Chemicals) and fill the tank in my boat with said water. This water will stay nice and clean for roughly 4 WEEKS now. Other boaters have come to my house and picked up the water for their boats and they all love it.

About HDC Product Devices


Removes suspended particles and heavy metals that cause haziness in the water. The particles and metals will clump together as they run through the HDC Products device and either get captured in the filter or fall out of suspension and removed (with normal maintenance).


The HDC Products device is made of high-quality polyvinyl chloride (PVC), the same that is used in your plumbing and requires: 

  • NO electrical power 
  • NO grounding necessary
  • Has NO moving or replaceable parts
  • Requires NO maintenance


The HDC Products device comes with the industry leading 10-year non-prorated warranty for all parts and workmanship from KD Enterprises Inc.

(BBB accredited, A rating)

All Natural Benefits:

Hydrodynamic Cavitation has been studied for over 100 years and is presently in use all over the world in different applications, and has been proven to naturally:

  • Kill pathogens and bacterias
  • Remove large percentages of heavy metals
  • Create a negative ion charge in the water
  • Create “restructured water” (H2O to H3O2)
  • Deconstruct various unwanted chemicals
  • Allow vegetation to thrive by more than 20-30%
  • Increase the oxidation reduction potential (ORP)
    of the water
  • Slow down water evaporation process by 250%.


Other Benefits:

  • The HDC device reduces required chemicals by 80% naturally!
  • Lowers corrosive effects from high acidity of chemicals.
  • The HDC device creates “structured water” that slows down evaporation in outdoor pool and spas by 250%.
  • Lowers calcium phosphate deposits.
  • Works with or without an existing “secondary source of sanitation” device, such as UV and Ozone-related products. Works on all salt and chlorine systems.
