Ultraviolet Water Sterilization

In the pharmaceutical industry water is considered to be the most crucial ingredient. Water is purified from soluble and insoluble impurities by reverse osmosis and electrical deionization.

The purified water is stored in tanks. As far as we all know, water is the source of all living creatures, and water that does not contain salts is an ideal source of life for microorganisms. If no necessary measures are taken, biofilm will appear on the internal surfaces of the storage tank and pipelines very soon. Moreover, the water itself will become unsuitable for the manufacture of medicines. The standard obliges to take various measures such as: ensuring constant liquid movement, maintaining temperatures unfavorable for the growth of organisms, etc.

One of the most effective methods is generally admitted to be water treatment with UV radiation of 254 m-9. A certain dose of radiation destroys the DNA of microorganisms, depriving them of the possibility of reproduction.

The energy exposure required to decontaminate the infectious agent by 90 % (in purified water) is usually 30 J-3 / cm2 for viruses and bacteria.

We recommend placing the UV reactor on before the water enters the storage tank both from the osmosis and from the water distribution loop, since the movement of water in the tank is usually much slower than in the pipeline and the risk of biofilm formation on the tank walls is much higher than in the pipe. Therefore, it is necessary to deactivate all potentially dangerous microorganisms in the streams entering the tank.

Our company has developed a range of UV reactor Rocket UV which was well-proven in practice.

The table below describes all the risks that a user needs to consider when installing a UV reactor in their purified water distribution system:

N Risk description Risk minimization method Method
1 "Shading". Microorganisms can shade each other. 1. The turbulent flow contributes to a uniform distribution of the probability of a particle entering the UV radiation zone.

1. Creating "barriers" inside the hull to increase turbulence.
2. Excess radiation power. 2. in the calculations a redundancy of 50% was taken.
2 "Radiation efficiency". Amalgam lamps degrade over time. Chemical cleaning of pipelines can disrupt the transparency of the quartz flask. The lamp may fail. 1. Inverse connection- constant intensity control. 1. Radiation intensity sensor.

The reactors can be in horizontal:

And vertical versions:

Model range of reactors:

Our company can also calculate and manufacture the UV reactor according to the characteristics required by the customer

Control system:

The reactor can be operated both separately and by integrating it into a reverse osmosis control system or a purified water storage and distribution system of purified water. During the lifeсycle of the lamp it degrades, thus the lamp initially starts working at 80% of its power.

The intensity sensor monitors the required radiation dose as the lamp degrades, the system "adds" power to it until it reaches 100%. After this point, the lamp continues to degrade, and the control system warns the User about the urgent need to replace the lamp. The system signals a crash if the UV radiation level is below the minimum permissible value.
