Details

Peracetic acid (PAA) is an extremely strong oxidizer widely used in the food industry for disinfection of piping systems and processing equipment.  It is also used for spray washing of food products, and for disinfection of cooling water systems.  As a disinfecting agent, PAA is often preferred because it produces no harmful breakdown products.  

As with any disinfection system, maintaining proper residual values is the key to effective pathogen control.  To facilitate reliable chemical feed control, ATI has developed an on-line monitor cable of providing real time measurement of low levels of PAA in solution.  The Q46/85 Peracetic Acid Monitor uses a direct sensing polarographic probe.  The probe is typically used in a flowcell, but a submersible sensor is also available.  A permeable diffusion membrane isolates the sensing electrodes from the measured sample, providing long-term stability without electrode fouling problems. The measurement is selective for PAA and is not affected by changes in hydrogen peroxide concentration, which is always present in PAA solutions.

Peracetic acid sensors are amperometric devices isolated from the water by a permeable membrane.  As PAA diffuses through this membrane, it comes in contact with an active electrode and is reduced on the surface.  The net effect is that the sensor generates a current proportional to PAA concentration.  An integral RTD in the sensor provides for automatic temperature compensation, allowing the sensor to operate accurately over a range of 0-50° C.
 
Peracetic acid sensors are capable of operating over a fairly broad concentration range, from a low range of 0-20 PPM up to a high range of 0-2000 PPM.  Systems will operate with good sensitivity down to 0.2 PPM and respond to changes in concentration within about 60 seconds, making them useful for automatic control.

Peracetic Acid sensors require a steady flow of sample across the membrane at the tip of the sensing assembly.  ATI offers options for flowcells, including the standard constant-head overflow system, and a sealed flowcell for pressures up to 50 PSI. For simplicity of installation, complete flow control assemblies are available. Panel assemblies are available with or without a flow switch and can greatly reduce installation time. For open tank installation, a submersible sensor is available. Sample agitation is required as PAA sensors cannot be used in still water.

Ice Fishing With A SondeCAM Underwater Fishing Camera

Thinking of hitting the ice with a SondeCAM underwater fishing camera? Due to its rugged design, you won't have to worry about it handling the harsh elements. However there are a few simple tricks to get the most out of a FishSens SondeCAM while ice fishing. You won't have to do anything to modify the SondeCAM itself, but you are going to have to bring a few extra things. Most importantly we are going to need a power source. Unless you are hauling your gear with a truck, you'll want something more portable than the battery you used in the boat. Pick up an inexpensive and maintenance-free 12-volt, 9-amp battery. It is going to provide plenty of power, but will be much lighter and take up less space.

Size Them Up With A SondeCAM Underwater Fishing Camera

We've all felt the frustration of weeding through a school of dinks to catch a "keeper." Often the small fish outnumber the bigger ones and they are typically more aggressive. Sometimes there's no choice but to deal with it, as is often the case with open water fishing. However a frozen lake involves a vertical presentation and a stable platform, it's a perfect situation to pick and choose which fish you want. Once you locate a school and get set up it's time to start sizing them up with a FishSens SondeCAM underwater fishing camera. It can be mind-blowing just how big some of these schools of fish are and also how outnumbered fish of a desirable size can be.

In Ontario Lakes, Non-Native Bass Impact Native Fish

It’s no secret that anglers have been the means by which invasive species and non-native fish have spread to new water bodies in the past. Fishermen have even been known to transport some of their favorite fish to new areas on purpose so that they can catch them a little closer to home. And the results of those actions have not always been ideal. In Ontario, Canada, fishermen have taken non-native bass and stocked them into what were historically lakes dominated by brook and cutthroat trout. The actions have impacted ecosystems, but scientists have been unable to broadly study the effects because they didn’t have enough data. But that is no longer the case for some Ontario lakes, as a study from biologists at the University of Toronto shows.
