Demineralised process water: Options for the modular cabinet system

Options for the modular cabinet system

UV Disinfection Mini

UV disinfection is used to treat water in order to combat potential microorganisms such as bacteria, viruses and protozoa. UV stands for the UV radiation that is produced by special UV lamps. The principle of UV disinfection is based on the inactivation of the DNA or RNA of the microorganisms. This prevents them from multiplying and causing diseases. The relevance of UV disinfection is based on the fact that UV radiation is effective against numerous microorganisms such as Giardia and Cryptosporidium, as well as viruses and protozoa. Most pathogenic organisms in water can be killed, resulting in a high inactivation rate. Unlike other disinfection methods such as chlorination or ozonisation, UV disinfection does not require the addition of chemicals to the water.

No unwanted additives are produced and it does not change the taste or smell of the water. UV disinfection is a reliable method for killing microorganisms. The effectiveness of the disinfection remains unchanged if the UV lamp is properly maintained. No chemicals are used in UV disinfection, which is why there are no harmful residues in the water or in the environment. It is an environmentally friendly disinfection method that reduces the ecological impact of water treatment. It should be noted that although UV disinfection is an effective method of killing microorganisms, it is not designed to eliminate pollutants, particles or chemical impurities in the water.

The additional UV system is integrated into the plant’s continuous recirculation system.

Pyrogen filter

A pyrogen filter is a special type of filter used to remove pyrogens from water.

Pyrogens are substances that can trigger an immunological reaction in the body, especially an increase in temperature.

These are generally endotoxins that are excreted by bacteria such as Escherichia coli (E. coli). A pyrogen filter consists of a filter element with a pore size that is usually between 0.1 and 0.2 micrometres. This enables the filter to effectively retain particles and microorganisms, including pyrogenic bacteria in the water. The pyrogen filter is used in the modular water treatment system after other process stages such as filtration and disinfection. Once the water has been freed of particles and microorganisms, it passes through the pyrogen filter to eliminate potential pyrogens. To ensure optimal instrument quality for operations, pyrogen filters are particularly important in areas where the absence of pyrogens in the water is of crucial importance, such as in the outpatient care sector.

Pyrogen filters are of great importance in water treatment as a whole, as they ensure water quality and purity and reduce the potential exposure to pyrogenic substances.

The additional pyrogen filter is positioned directly behind the UV system and can therefore also be integrated into the system’s continuously operating recirculation system.

Conductivity measurement on mixed bed

The electrical conductivity of aqueous solutions in the lower range is measured using an integrated two-electrode screw-in measuring cell of 3/4 inch without temperature compensation.

Examples of use:

  • Softener cartridges
  • demineralisation
  • reverse osmosis
  • mixed bed cartridges

Added value:

  • operation on 9 V DC via supplied plug-in power supply
  • 1 potential-free relay with switchable relay control
  • Limit value display via LEDs

The conductivity measurement is located in the second mixed bed cartridge and continuously monitors whether the recommended limit value of 1 μS/cm is not exceeded.

Lifting station

The function of the lifting station is to reliably drain the waste water generated from the various process steps. The waste water from regeneration of the softening system and the concentrate from the reverse osmosis system are the main volume flows. The lifting unit also collects the rinsing water that accumulates when the input filters (especially the activated carbon filters) are changed, as well as the intermittent waste water flows from the silicate measuring device and the system separator. If the waste water pipes cannot be connected to a ground-level waste water connection, we recommend using a lifting unit.

Viewing windows

The Rittal cabinets can be equipped with viewing windows that provide an overview of the measurement technology. Viewing windows in Rittal cabinet systems offer various advantages. This makes it possible to visually inspect the devices inside the cabinet without having to open the cabinet. This makes it easier to monitor, maintain and troubleshoot components without compromising the integrity of the cabinet. Typically, the viewing windows are made of a transparent material such as glass.
