Calibration of chemical injection pumps is important to ensure that the proper amount of water treatment products are being fed to your systems. All chemical feed pumps are designed to pump at a certain rate; however, the actual flow rate can vary depending upon many conditions. Factors such as discharge pressure, chemical viscosity, type of suction (flooded or lift), and pump age will effect the flow rate. This simple procedure should be used on a regular basis to ensure that you are feeding the proper amount of product to your water systems.
Prior to running calibration on chemical injection pumps (like the AKL603) review product MSDS forms and use proper personal protective equipment.
If you are using the same calibration cylinder to calibrate multiple pumps, be sure to rinse it with water between calibrations.
(Pump capacity, gph x Pump speed, % x Pump stroke, %)
(1, gph x 50% x 50%) = (1 x 0.5 x 0.5) = 0.25 gph
((mL pumped, 1 min x 60 minutes) / 3,785)) = gallons per hour
(50 mL x 60 minutes) / 3,785 = 0.79 gallons per hour
Depending on your system, you will need to adjust your pump or controller settings to account for any difference between the design and actual feed rates.

Most people have heard of ozone thanks to media coverage about pollution and the ozone layer. But for many, that is where their knowledge ends. The first thing you should tell a homeowner is that ozone is nothing more than O3—three oxygen atoms bound together.
That extra oxygen atom wants to hook up with other material, like unwanted microorganisms in water filtration systems. For the purpose of disinfecting water, ozone comes in contact with contaminants and pathogens that can damage equipment and get in the water supply. The extra oxygen atom oxidizes the contaminant and the O3 becomes O2—just plain old oxygen.

It was shown that after 30 seconds of in vitro direct exposure to ozone, 99 percent of the viruses are inactivated. Although this evidence is of considerable importance, outside of the laboratory models, there are various parameters that influence the time required to obtain the same result. First of all, it was seen that the inactivation of 99% of viruses by ozonation requires its spread at concentrations higher than those necessary for the bacteria. A longer exposure time, about 30 minutes, is necessary for the treatment of the surfaces of the environment (surface viruses), while for any viral particles suspended in the air (airborne viruses) 8-10 minutes are enough to remove 99.9% of them. Viruses in water are more susceptible to ozone inactivation and short contact time, about 1 min or little more, are sufficient to inactivate 99% of them.

A positive displacement pump moves a fluid by repeatedly enclosing a fixed volume, with the aid of seals or valves, and moving it mechanically through the system. The pumping action is cyclic and can be driven by pistons, screws, gears, lobes, diaphragms or vanes. There are two main types: reciprocating and rotary.Positive displacement pumps are preferred for applications involving highly viscous fluids such as thick oils and slurries, especially at high pressures, for complex feeds such as emulsions, foodstuffs or biological fluids, and also when accurate dosing is required.
