Gas chlorination has been around since the 1920s and has been the industry standard since that time.  Over the last 25 years there has been much political pressure applied to replace chlorine gas in the name of “safety”.  While chlorine gas has historically provided the most bang for the buck, additional requirements for safety equipment and safety training have raised the cost to disinfect with chlorine gas.  With our many years of experience with gas chlorination systems we can make sure that you have a system that meets your needs and the accepted safety standards.

Scales will allow you to monitor your chemical usage.  Depending on the model you select you may just have a local display indicating remaining chemical or you can have electronic models that will allow you to transmit remaining weight to your SCADA system and generate low weight alarms or even excessive rate-of-change alarms.

If you determine that chlorine gas is the best disinfection method, you need to have an automatic gas detection system to alarm if there is a chlorine gas leak. Alarms can be local or transmitted to your SCADA system. In addition, the leak detector can be connected to an automatic chorine emergency shut-off actuator system (see below).

While there are many liquid chemicals used in the water and waste water industries, sodium hypochlorite (bleach) is the dominant chemical.  12.5% bleach is one of the more difficult chemicals to pump because it is very “gassy”.  The chlorine gas will come out of solution and buildup in the pump and then gas bind the pump head.  With our many years of experience we can help make sure that you get the correct pump for your application.

Chlorine emergency shut-off actuators mount directly on the chlorine cylinder valve and will automatically close the chlorine cylinder when an alarm contact is received.  The alarm contact can be from a chlorine gas detector or a panic button.  Emergency shut-off actuators are the cost effective means of meeting all national fire code requirements for chlorine safety devices.

Wall mount chlorine residual analyzers provide a continuous record of the residual present in your process.  They can also provide high and low alarms to notify you that the disinfection process is not operating properly.

While conversion of salt water to chlorine has been around since the early 1900s it was always a large scale process, until the early 1990s.  In 1994 Miox, Inc. started producing on-site generators sized for municipal water wells.  If safety is a concern, then on-site generation of sodium hypochlorite (bleach) is the only method to consider, the solution that is generated is less than 1% concentration and non-hazardous. The only chemical handled in the process is salt.

Miox, Inc. also offers a mixed oxidant generator that produces 0.4% sodium hypochlorite plus other oxidants that produce a stronger disinfectant than just sodium hypochlorite.  Miox has 3rd party studies that show that the mixed oxidants will kill Giardia and Cryptosporidium.

Over the last 30 years operators and engineers have analyzed the entire water production and delivery system, with the exception of storage tanks.  During the last few years operators and engineers have started to look at storage tanks and how they fill and drain.  People are recognizing that many storage tanks do not do a good job of blending the water that comes into and out of a storage tank.  Many times a layer of stagnate water will develop at the top of the tank that may have little or no disinfection present.  When something in the system happens that requires a full draw down of the tank, this questionable water can be pulled into the distribution system.

Several years ago, Pax Water Technologies, Inc. set out to create a small low power mixer that could be installed into existing storage tanks to overcome any tank mixing problems.  Using biomimicry and advanced computational fluid dynamics modeling, they have created a small low powered (300 watts maximum) mixer that can handle storage tanks up to 7 million gallons.
