SM-50 Discontinued – Why the OEM-3 is a great alternative

The SM-50 Ozone Controller has recently been discontinued. However, we are offering the OEM-3 Ozone Controller which is a great alternative. Below we will list some of the similarities and differences between the two ozone controllers to show you why the OEM-3 is a solid alternative. Please note – some of the data below also refers to the OEM-1 and OEM-2, more information on those products are also available on our website, but when it comes to a replacement for the SM-50, we highly recommend you check out the OEM-3.

The OEM-3 and SM-50 are both Original Equipment Manufactures (OEMs) Ozone Sensors that are designed with state of the art sensor technology that can be integrated into your own equipment.  OEM Sensors are a great addition to any Ozone System to help ensure any ozone leaks are detected and the Ozone Generation system is shut off.  The OEM sensors can be integrated into your system to control your Ozone Generation system and turn it off/on based on your preset levels. Below we will lay out the benefits and differences between the EcoSensors OEM-3 and the Aeroqual SM-50 OEM Ozone Sensors.

State of the Ozone Water Treatment Industry

Ozone is a widely used agent for water treatment including public drinking water, industrial wastewater, purification of process water, aquariums, bottled water, ground water remediation and aquaculture, among many others. Ozone finds value in these applications because it can provide multiple benefits in water treatment while decomposing back to oxygen after use. The benefits of ozone include:

•Disinfection – ozone is a biocide that can inactivate a wide range of microorganisms including virus and bacteria.
•Oxidant – ozone is capable of directly oxidizing various organic compounds, including those of emerging concern such as pharmaceuticals and personal care products found in our drinking water sources, as well as organic compounds found in industrial wastewater.
•Advanced oxidation – In combination with peroxide or UV light, ozone can be the base of an advanced oxidation process that can oxidize virtually any organic compound including difficult to treatment materials such as 1,4 dioxane.

This article will touch on some of the major existing applications and some emerging applications for ozone.

Public drinking water treatment
Chart 1 shows the distribution of ozone use in US public drinking water. Ozone provides several benefits to drinking water facilities. These include primary disinfection, taste and odor removal, color removal, removal of inorganic materials such as Fe, Mn and H2S, enhanced filtration via a micro-flocculation effect and removal of certain organic compounds. In a well-engineered process, several of these benefits can be achieved in a single injection of ozone. Being able to accomplish several treatment objectives at the same time make ozone an excellent choice for certain drinking water plants. This explains the growth of ozone for this application.

Municipal wastewater reuse
Because of water shortages caused by growth in water demand as well as loss of water supply caused by drought, more cities are thinking about reusing their wastewater for drinking water, either directly or indirectly. Several facilities have already been built using membrane-based technologies. This is a proven approach but comes with several notable drawbacks. First, you need a find a place to dispose of the waste brine rejected from the RO membranes. In coastal locations, the brine can be rejected to the ocean. In other locations it is not as simple. The second factor is cost, because of the high pressure needed in RO membranes, the electrical demand to treat the water is high.

Ozone in combination with biologically active filters (ozone-BAF) can be used to treat municipal wastewater to achieve high degrees of water purity at lower cost than membrane processes and without the need to dispose of a brine waste. Currently, large scale trials are being run by the Hampton Roads Sanitation District, in Eastern Virginia to demonstrate this technology through their SWIFT project. Other water authorities are also running ozone-BAF pilot trials. If successful, ozone-BAF could provide inland wastewater facilities with a technology to reuse their wastewater for drinking water.

Advanced oxidation processes
Another emerging application for ozone is in advanced oxidation. Advanced oxidation refers to processes that produce hydroxyl radicals (•OH). The hydroxyl radical is one of the strongest and fastest acting oxidants that can oxidize virtually any organic compound. They can be produced in a variety of ways, but ozone with peroxide and ozone with UV are two such methods. The advantage of the ozone routes is that little if any by product is left after complete and pH adjustments are not required. An important application of ozone based advanced oxidation is the removal of 1,4 dioxane from ground water contaminated with solvents. Dioxane is not readily air stripped from water, absorbed on activated carbon, or oxidized by most chemicals. Advanced oxidation by ozone and peroxide has been proven to be effective in removing the dioxane from the water via oxidation. Ozone with peroxide has also found use in industrial wastewater applications where other methods were not able to remove difficult to treat organic compounds. The use of advanced oxidation appears to be a growing technology for water treatment and ozone-based processes are a growing part of this application.

Biosolids reduction
Wastewater treatment plants utilizing the activated sludge process typically produce excess sludge that needs to be removed and disposed of from the process. Ozone has been shown in the literature and in commercial application to offer an alternative method for reducing excess sludge. This process involves exposing a portion of the activated sludge to ozone. Some of the bacteria that make up the sludge are lysed via exposure to ozone releasing COD into the wastewater. Even though some of the cells are damaged or killed, the overall process generally does not show an increase in BOD/COD leaving the process.

Depending on the amount of ozone required per unit of sludge removed and the costs associated with the current handling of the excess sludge, ozone can represent an economical alternative with conventional sludge handling processes. Ozone also offers other potential advantages to the activated sludge process including a reduction in bulking/foaming, scum control and improved denitrification. A number of wastewater treatment plants in Europe have adopted this technology and have realized a 30-40 percent reduction in excess sludge with no loss of wastewater treatment performance. A new installation is planned for the US later this year at a chemical manufacturing plant.

PFAS removal
PFAS are a group of various fluorochemicals including PFOA, PFOS, among others. They are of emerging concern since they are distributed widely in the environment, do not readily breakdown in the environment/human body and can accumulate over time. There is some evidence that they may have adverse impacts on human health. US EPA points to studies of PFOA and PFOS that show: reproductive and developmental, liver and kidney, and immunological effects and tumors in laboratory animals. As a result, the agency is studying regulation of these compounds.

A novel approach to PFAS removal is ozofractionation. Ozofractionation is a form of foam fractionation, a method to remove hydrophobic materials from water. In ozofractionation, ozone is used an oxidant, as well as the foam-forming gas. Proposed advantages for using ozone as the bubble forming gas include co-contaminant reduction and smaller bubble sizes. Smaller bubbles result in higher surface area to volume ratios and thus more material can be captured for a given volume of gas. Formation of hydroxyl radicals around the bubbles may result in negative charges that better hold the PFAS molecule.

Conclusion
Ozone continues to find new applications in water treatment while expanding its existing applications. The future looks bright for the use of ozone in various parts of the water treatment industry.

Custom RCB-1

Our RCB-1 Relay Control Box can be used for a wide array of different applications. It is most commonly used to regulate gas levels as an accessory to ozone monitors. Another popular application is to use it in a custom ozone chamber, where the RCB-1 is connected to an ozone monitor, which tracks the ozone levels inside of a given chamber. Once the ozone level in the chamber reaches certain point, the ozone monitor will send a signal to the relay control box, which will then send a signal to an ozone generator to stop producing ozone for the chamber. Once ozone levels in the chamber drop past a desired level, another signal will be sent through telling the ozone generator to once again begin producing ozone until the chamber gets back to an ideal level. Simply put, the RCB-1 is most typically used to regulate the ozone levels for a given circumstance.

We recently had a customer that wanted to regulate the production of his oxygen concentrators. After a call with one of our ozone specialists, they came to the conclusion that a custom RCB-1 would be the best option. Our shop technicians were able to make an RCB-1 with a built-in pressure gauge that would allow the relay control box to regulate the pressure at which the oxygen concentrators were performing.

Our RCB-1 can be found here.

Ozone Generator Dust Disaster

Dust-Filled Ozone Generator

All is not lost when you open your ozone generator cabinet one day and find everything covered in dust.  The dust is not toxic, just messy.  It has come from the oxygen concentrator which uses a clay based zeolite material as a sieve to filter out Nitrogen from the air and supply dry oxygen for the ozone generator cells.  The dusting can be caused by moisture getting into the sieve beds, excessive flow or pressure through the oxygen concentrator.  Let’s work on getting repairs made first and then discuss ways to prevent this from happening again.

  1. The oxygen concentrator (aluminum tank assembly on the upper left side) needs to be removed and either replaced or rebuilt.  This assembly will be supplied either with 120 volt or 24 volt power.  You will need to disconnect this power along with the air feed hose and smaller 1/4″ ID oxygen tube coming off the oxygen tank.  The air hose is usually a 1/2″ barb fitting and the oxygen fittings at the other end are a quick connect type fitting. 
  2. Clean up the dust with a long bristle brush and vacuum or compressed air blower. 
  3. Remove the small tank from the oxygen concentrator.  This a storage tank/surge tank and could be full of dust.  It will also have an orifice on the outlet.  Make sure this is open.
  4. A network of green tubing with check valves and orifices are at the top.  These check valves will need to be replaced and the orifices open. 
  5. Order new parts.  It is likely that all the filters need to be replaced.  The air compressor inlet filter, two coalescing filters to remove moisture and dust from the compressed air,  and for some machines, an oxygen filter.  (see the parts list below).  When the oxygen concentrator dusts, you will need to order new or rebuilt sieve beds.  It is also likely that the valve set is compromised and the Nitrogen exhaust mufflers are plugged with dust.  The mufflers can be hard to clean, and are fairly inexpensive, so it is recommended to replace them.  The valve is a shuttle valve which is sensitive the contamination and sticking.  It can be rebuilt, but sometimes it is difficult to get it to work as well as new and it may be best to replace it. 
  6. Once everything is cleaned up, use the compressed air to gently blow some air through the ozone generator to make sure it is not plugged.  Some generators are more sensitive to getting plugged and will have an oxygen filter to prevent this.  Do not put too much pressure on the ozone generator. 
  7. Replace the filters.
  8. Re-assemble the oxygen concentrator with new sieve beds, oxygen check valves, and valve set.  Mount back in place.  It may be easier to connect the oxygen lines before mounting. 
  9. Turn the system back on.  Leave the ozone off.  The compressor will turn on and the oxygen concentrator will begin cycling the valve to direct air through the oxygen concentrator.  The compressor will reach 20-40 psi as the concentrator cycles air through the concentrator.  Exhaust nitrogen will blow out of the muffler. 
  10. Oxygen flow and pressure will register on the cabinet door. 
  11. When the oxygen supply is stabilized and flow appears normal through the ozone generator, you can turn on the ozone generator. 

The most common cause of dusting in an oxygen concentrator is excessive moisture in the feed air.  If the ozone system is located in an environment with high humidity there are three things you could do: 1) move the equipment to a dryer environment and plumb the ozone to the point of use, 2) Plumb a refrigerant air dryer between the air compressor and the coalescing filters, 3) plumb an air hose to extend the air inlet filter for the compressor to a dryer location.  Moisture, along with excessive oxygen flow rates are the leading cause of concentrator failure.  When the unit is running, adjusting the oxygen flow to a lower rate will extend the life of the concentrator.

New Product: The FIOX Water System

The FIOX iron removal filter oxidizes any dissolved iron in the water with oxygen and ozone. The oxygen is pulled in from ambient air and the ozone is generated on site with a small ozone generator. The oxidized iron is filtered out with the back washable sand filter. The I-OX filters utilize an air injection system to remove iron (ferrous or clear water), manganese, and sulfur from the water via both oxidation and filtration. Unlike other iron filter alternatives, I-OX technology is designed for use in a single tank and valve system configuration, reducing both acquisition and maintenance costs yet delivering years of trouble-free service. No chemical additives or air compressors are required for operation or regeneration with the I-OX filters advanced design.

How does the I-OX filter work? During system regeneration, an air pocket is created when air is drawn in through an injector located in the brine port. During service, untreated water passes through the air pocket oxidizing any iron, sulfur, and manganese. The particles are filtered out. Then the system’s regeneration cycle backwashes the bed and replaces the air pocket, allowing the process to begin again.

Principles of Operation 

The ozone component provides protection from the common problem of iron bacteria bio-film which will plug up iron filtration systems unless the bacteria are controlled. Ozone is an energized O3 form of oxygen which not only accelerates oxidation of iron, but also destroys bacteria in the process.

Jacob’s Ladder Demonstration

Here we have a makeshift Jacob’s Ladder, created by one of our ozone experts. The Jacob’s Ladder does a good job of giving a visual explanation for how ozone is created on an extremely small scale. What you are seeing is essentially what is happening on the inside of an ozone generator to create ozone. The process is really quite simple, the arc that you can see is just heated ionized gas. The gas molecules like oxygen are broken down to where they are at an atomic level and then ionized. While the oxygen molecules are broken down, they can more easily collide and bind with different molecules. For the creation of ozone, the oxygen molecules bind with O2 to create O3.
