From Prototype to Product: How CRS Made Mainline Nanobubble Generation Practical

In less than one year, Chemical Reduction Solutions transformed a field-built prototype into NanoSoft™—a compact, fully productized system designed to make cavitation-based nanobubble generation practical on the main water line of a building.

Hydrodynamic cavitation has the potential to improve how water is treated throughout a facility. But bringing that technology to a building’s main water line presents a fundamental engineering challenge: water demand is constantly changing.

One moment, a facility may be using very little water. The next, multiple pieces of equipment, fixtures or process systems may begin operating at the same time. That variability matters because cavitation-based nanobubble generators perform best within a defined operating range.

CRS set out to solve that problem.

The Challenge: Variable Building Water Demand

Traditional inline cavitation devices rely on water flowing through the device at the correct rate. When the flow is too low or too high, the device may not produce the intended cavitation conditions consistently.

That can make direct installation on a building’s main water line difficult. Real buildings do not operate at one predictable flow rate. Their water demand fluctuates throughout the day based on production schedules, equipment operation and occupant use.

Rather than expecting the building to provide the ideal hydraulic conditions, CRS designed a system capable of creating and maintaining those conditions itself.

Prototype 1: Proving the Concept

The first prototype was built to answer a basic question:

Could we create a dedicated treatment loop that allowed a cavitation-based nanobubble generator to operate independently from changes in mainline water demand?

The early system was functional, but it was very much a prototype. It used field-assembled piping, a circulation pump and a cavitation reactor installed around the main water line.

It was not designed to look polished. It was designed to prove that the concept worked.

The prototype demonstrated that a dedicated circulation loop could maintain a more consistent operating flow through the cavitation device while allowing the building’s main water supply to continue responding normally to fluctuating demand.

That proof of concept became the foundation for everything that followed.

Prototype 2: Improving the System

The second-generation prototype focused on refining the hydraulic design and making the system easier to install, operate and service.

CRS tested different piping arrangements, pump configurations and component locations. Each iteration provided new information about how the system behaved under real-world conditions.

The objective was not simply to make the equipment smaller. It was to make the entire system more practical.

That meant improving:

• Hydraulic consistency

• System reliability

• Installation flexibility

• Component accessibility

• Serviceability

• Overall footprint

Prototype 2 moved the concept much closer to a repeatable commercial system, but additional engineering was still required to turn it into a finished product.

NanoSoft™: A Fully Productized Mainline Solution

The result is NanoSoft™, a compact, installation-ready system designed to bring cavitation-based nanobubble treatment to a building’s main water line.

Rather than depending entirely on the building’s variable water flow, NanoSoft uses its own circulation pump and treatment loop to create controlled operating conditions through the cavitation reactor.

This allows the system to treat water while accommodating the normal fluctuations that occur throughout a facility.

The current NanoSoft design is dramatically more compact and standardized than the original prototypes. The piping arrangement has been simplified, the components have been consolidated and the system has been designed for repeatable field installation.

The evolution shown in the photo represents more than a change in appearance. It reflects a year of testing, troubleshooting, redesigning and learning from real installations.

What Product Development Really Looks Like

New products rarely emerge fully formed.

They begin with a problem, followed by an imperfect first attempt to solve it. The first design creates data. That data leads to a better design, which creates better data. The process continues until the system becomes simpler, more reliable and easier to deploy.

For CRS, the journey from Prototype 1 to NanoSoft took less than twelve months.

During that time, the team moved from a custom-built proof of concept to a commercially scalable product designed for installation upstream of water-using equipment throughout a facility.

The process followed a straightforward philosophy:

Build. Test. Learn. Simplify. Repeat.

The Future of Mainline Nanobubble Treatment

NanoSoft represents an important step toward making cavitation-based nanobubble technology more accessible for commercial and industrial water systems.

By addressing the hydraulic variability of building water demand, CRS has created a practical platform for treating water at the mainline level rather than only at individual pieces of equipment.

We are proud of how quickly the technology has progressed—and even more excited about where mainline nanobubble treatment is going next. A Practical Alternative to Salt-Based Water Softening

Car wash operators and industrial membrane filtration users are increasingly switching from traditional salt-based water softeners to NanoSoft™.

By eliminating or reducing reliance on salt regeneration, NanoSoft can lower operating expenses associated with salt purchases, regeneration water, wastewater discharge and routine softener maintenance. It also reduces the labor required to receive, move and load heavy bags of salt.

For facilities operating reverse osmosis systems, the benefits extend beyond softener savings. NanoSoft is designed to help prevent scale and biofilm from fouling membranes and other water-contact surfaces. Users can track performance through measurable indicators such as RO permeate quality, membrane pressure differential, production rate, cleaning frequency and overall system uptime.

The result is a simpler pretreatment approach with the potential to deliver:

• Lower salt, water and wastewater costs

• Less maintenance and manual labor

• Longer operating runs between cleanings

• More consistent RO permeate quality

• Improved membrane performance and service life

  
  

For CRS, NanoSoft is more than a product-development success story. It represents a new way for commercial and industrial facilities to improve water-system performance while reducing the cost, waste and operational burden associated with conventional salt-based softening.
