For this week’s Wednesdays | Weekly Product to Watch we will be checking out the variety of ozone compatible fittings that Ozone Solutions offers on our website.

Need to connect your tubing to your Ozone Generator, or need a smaller size connection? We have all the fittings you might need. Ozone Solutions offers both kynar fittings and stainless steel fittings. What are the benefits of each you might ask? This week we will look at the benefits of the kynar fittings. (Come back next week to learn about the benefits of the stainless steel fittings.)

Kynar fittings are made from Polyvinylidene Fluoride or PVDF material. Kynar fittings can operate in pressure up to 220 PSI, and can be used in temperatures ranging from -80 to 226 degree Fahrenheit. One of the benefits of kynar is it meets ANSI/NSF Standard 51, which means it’s certified for use in the food and beverage industries. Ozone Solutions offers many types of compression, barb, and pipe connection fittings in a variety of styles: adapter, elbow, tee, and union, just to name a few! 98% of the kynar fittings that we show on our website are in stock for immediate shipment!

How do bubble diffusers work to dissolve ozone into water?

Ozone Transfer via Bubble Diffusion

This article is intended to answer, how do bubble diffusers work to dissolve ozone into water? Ozone is a gas, therefore proper gas/liquid contact mechanisms are critical to efficient system design. Bubble diffusers are a popular, inexpensive method to inject ozone into water. The ozone gas transfer area occurs immediately at the interface between the ozone bubble surface and the surrounding water.

Bubble Diffusion:

Diffusers permit ozone gas to pass through a porous membrane thus creating many small ozone bubbles in the water, similar to a fish tank air stone. As the ozone bubble rises, the gas at the bubbles edge will transfer into the water. Using a diffuser requires enough pressure to overcome the height of the water and any restrictions in the diffusers due to hole size.

Advantages:

  • Low Cost
  • Easy to setup
  • Low energy – does not require a water pump

Disadvantages:

  • Inefficient – ranges from 10-25% (dependent on water height)
  • High water columns/vessels are typically required
  • Difficult to use in pressurized water flows
  • Diffuser pores can become plugged requring cleaning

– The diameter of a gas bubble has a dramatic impact on
surface area as shown below!
– Be picky when it comes to selecting a bubble diffuser. It can mean the difference between success and failure.
– The transfer of ozone gas into water is directly related to its surface area (total bubble surface area).
– It is critical to prevent the water from back-flowing through the bubble diffuser and going into the ozone generator. The best method of prevention is to use multiple check valves (for redundancy) and a water trap .


4.8 square ft. Dia. = 14.8 in. 1 bubble

185 square ft. Dia. = 10 mm. 54,000 bubbles

1,800 square ft. Dia. = 1 mm. 54,000,000 bubbles

Conclusion: Additional smaller bubbles give you more mass transfer!

Ozone Check Valves

Posted by Joel Leusink on February 21, 2011 under Ozone Products | Read the First Comment

Check valves are a big deal in the ozone world.  This is the cheapest and easiest method of preventing water back flow into an Ozone Generator.  There are a variety of check valves and many different applications where they are used.  Due to the questions about check valves, I recently put together a list of information to help sort through the options.

A selection of ozone-compatible check valves - low pressure, high pressure, and stainless.

Which Check Valve is Right for Me?

This information is listed HERE at our Check Valve Page.

CVLP – Low Pressure Check Valve

  • Low pressure check valve for low pressure (less than 25 PSI)
  • Free floating diaphragm will seal with very small pressure differentials
  • Very low crack pressure < 0.25 PSI
  • Free floating diaphragm will not provide a positive seal every time, expect some water leakage through seal
  • Barbed fittings make this an easy check valve to install
  • Kynar construction and Viton seal will be ozone resistant up to ~5% ozone, also ozone by-products can deteriorate Viton seal

CVHP – High Pressure Check Valve

  • High pressure check valve for high pressures (up to 200 PSI)
  • Stainless steel spring and ball provide positive, tight seal
  • Crack pressure of ~2 PSI – (crack pressure may vary between valves)
  • Crack pressure of ~2 PSI – (crack pressure may vary between valves)
  • Male NPT connections require threaded connections to this valve
  • Kynar construction and Viton seal will be ozone resistant up to ~5% ozone, also ozone by-products can deteriorate Viton seal

CVSS – Stainless Steel Check Valve

  • High pressure check valve for high pressures (up to 200 PSI)
  • Stainless steel spring and ball provide positive, tight seal
  • Standard valve uses 0.5 PSI crack pressure, other crack pressures are available upon request
  • Open design offers very high flow, and very little flow restriction
  • Female NPT connections require threaded connections to this valve
  • Viton, or PTFE seal designs are available on stainless steel valves
    • PTFE seal will be most ozone resistant and longest lasting seal available.
    • Viton seal will be ozone resistant up to ~5% ozone, also ozone by-products can deteriorate Viton seal.
    • Viton is very pliable and will offer the most reliable seal.
    • PTFE is very rigid, small particulates will keep this material from offering a positive seal.

Ozone Solenoid Valves

Posted by Joel Leusink on March 26, 2010 under Ozone Products | 6 Comments to Read

We now offer stainless steel solenoid valves on our website.  They are ozone compatible and corrosion resistant, with the wetted parts made only of stainless steel and viton seals,  meaning reliable performance and a long lasting product that you can rely on. Along with being a useful addition to an industrial ozone generation system, these valves are also a great way to ensure years of service in even the most corrosive environments.

If your need requires a durable, damage resistant product to hold up against harsh environments, then these solenoid valves are perfect for the job. Even if you’re just looking for high pressure capabilities in a quality product, these will meet and exceed expectations.

SVSS-2M Ozone Compatible ValveThe first and smallest valve is the SVSS-2M. This solenoid valve has 1/8-in FNPT fittings and is capable of handling pressures up to 50-psi (3.5 bar). The most enticing feature of this product is that multiple valves can be connected together directly, creating a manifold style valve assembly. Not only will this cut down on the price of your project by eliminating fittings, it will also cut down on the space used, creating more room for larger components.  We use these on any project that requires a normally closed solenoid valve in an environment at 50 psi or less.

SVSS-4 Ozone Compatible SolenoidThe second valve we have to offer is the SVSS-4.  Weighing in at 1-lb, this is a slightly larger solenoid valve, but is made entirely of stainless steel utilizing viton seals.  This valve has 5/32-in FNPT, allowing for slightly larger fittings to accommodate your needs. Being able to withstand pressure up to 75 PSI (5 bar), it can get the job done in many situations. The nice thing about this solenoid valve is that even the body is entirely made up of stainless steel, making it the most resilient valve we have to offer. Not only is it ozone compatible and corrosion resistant internally, but it is also corrosion resistant externally as well. It is perfect for environments where general corrosion is a concern.

SVSS-6 Stainless Steel SolenoidThe third and final solenoid valve we offer is the SVSS-6 model, which allows for 300 psi (20.7 bar). With an inlet and outlet fitting size of 3/8-in FNPT, it has one of the largest orifice sizes available at this level of high flow and pressure capabilities. This, like the others, is ozone and corrosion resistant, making it one of the most useful valves we have. The other feature we offer on this model is a choice of AC or DC power options. We use this solenoid valve in most of the ground water remediation systems we build. The quality and reliability of this product has exceeded our expectations. The wetted parts on this valve are stainless steel and viton, ensuring a long life expectancy.
