Gas Chlorinators

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.

Tablet Chlorinators

Calcium hypochlorite (cal hypo) is supplied in 65% concentration. The other 35% are binders to hold the chlorine in tablet form until it is dissolved. While some of the binders do dissolve, not all of them do and will end up in the bottom of the solution tank. Also, when you dissolve cal hypo tablets the pH of the chlorine solution is raised into the caustic range. If you are dissolving your cal hypo tablets with hard water and you raise the pH of the hard water calcium carbonate with precipitate out of your water. This calcium carbonate will settle out in the bottom of the solution tank as well as the metering pump and piping. While Cal hypo is easy to use and store, it tends to be a high maintenance method of disinfection.

While Trochlor-s-trizinetrione (Trichlor) has been used in swimming pools for many years, it has recently been approved for use in drinking water. Trichlor is 90% chlorine and only 10% binders. The 10% binders all dissolve so they do not build-up in the bottom of the solution tank. Also, when Trichlor dissolves it reduces the pH of the dissolving water which has no affect on the calcium carbonate in hard water. Trichlor provides all the benefits of cal hypo tablets without the problems!

Once the cal hypo or Trichlor tablets are automatically dissolved into a day tank an educator or chemical metering pump is used to feed the chlorine solution whenever your well is running or your WTP is flowing.

MIOX On-site Chlorine Generator

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.

Chemical Metering Pumps

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.

FloMotion peristaltic pumps

Peristaltic (hose) pumps have been around for years but have been limited in pressure and flow rates. Because of this, they have typically been used in waste water applications. Improvements in tube/hose technology over recent years have greatly improved the operating range of peristaltic pumps and they are finding many more applications in the water industries.

The most beneficial use of peristaltic pumps is with 12.5% sodium hypochlorite solution (bleach). Many water facilities transitioned from chlorine gas to bleach in the name of safety, without realizing how much more difficult it is to feed bleach instead of chlorine gas. The biggest problem with bleach is that it is very “gassy” and will cause a diaphragm metering pump to gas bind (the same as air binding, but with chlorine gas). This happens because 12.5% bleach is very unstable. At 12.5% the chlorine gas that is in solution does not want to be in solution. When you shut off the metering pump the chlorine gas that is in the bleach in the pump head will come out of solution. When the pump is restarted the pump head is gas locked and will not pump. This requires intervention by an operator to get the pump re-primed and feeding again. Peristaltic pumps solve this problem because peristaltic pumps can pump gas, liquid or a combination of gas and liquid.

FloMotion Systems has a complete line of peristaltic pumps that are manufactured in the United States.

Chlorine Gas Leak Detectors

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).

Hydro Instruments

Chlorine Emergency Shut-off Valves

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.

Halogen Valve Systems, Inc.

Chemical Scales

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.

Forceflow

Chlorine Residual Analyzer

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.

Aqua Metrology Systems, Ltd.

On-line THM analysis

Aqua Metrology Systems, Ltd. has created the first on-line THM analyzer. Until now, THM analysis required that a sample be taken to a laboratory for testing by certified laboratory technicians. With the Aqua Metrology Systems, Ltd. THM-100 analyzer, the testing is done in the field automatically. Results can be stored and downloaded onto a USB memory stick, transmitted via Ethernet or 4-20 mADC signal.

For the first time, water operators can know how process changes are affecting their THM levels. With this capability operators can now control source water, power and/or chemical usage relative to THM control and be confident that they will not exceed THM limits. Depending on the water system, the savings could pay for the THM-100 in less than a year.

The THM-100 is manufactured in the United States.
