Filtration | Softening | Osmosis | Disinfection

All our air humidification systems work with perfectly filtered and hygienically safe water. Depending on requirements, the water passes through a filtration, water softening, reverse osmosis and disinfection unit. You can rest assured that our air humidification systems always provide maximum process reliability, efficiency and hygiene.

Filtration Unit

The water filter combination, including integrated water counter, prevents the particles and suspended solids in the feed water from entering our air humidification systems. The filtration unit consists of coarse filtration that can be cleaned by backwashing and subsequent fine filtration – for completely reliable protection.

Water Treatment Unit

To prevent calcify on the high-quality system parts and atomiser nozzles, water softening is introduced. The water previously purified in the filtration unit transforms to 0° German hardness by an ion exchange process. Different systems will be used to meet the individual requirements and needs of customers.

Ion exchangers are small plastic balls (permitted in drinking water) which can absorb ions from water and replace these with other ions. The hard water flows through the system and the dissolved calcium and magnesium ions are removed and replaced with sodium ions. This softens the water.

Reverse Osmosis Unit

The reverse osmosis unit is used to demineralise water and is an indispensable part of the overall air humidification system in all areas where the presence of minerals is undesired (e.g. pressure and painting applications).

Filtered and also softened water is pressed through a membrane. The result is pure water, the residues are washed down the drain. The special advantage of reverse osmosis is that in addition to removing dissolved minerals, it also separates out bacteria, germs, particles, and dissolved organic substances.

Reverse osmosis units with different litre capacities are integrated into the overall project based on customer-specific requirements. Reverse osmosis can also be used for process water (e.g. for printing machines).

Reverse Osmosis Unit

Disinfection

To guarantee the hygiene in our air humidification systems, either a selective disinfection process or an online disinfection process is implemented.

Selective Disinfection

Softened water or reverse osmosis water is conveyed under a UV lamp, exposing it to UV light of approximately 200 – 280 nm (UV-C range). This renders any existing bacteria, viruses, etc. harmless.

Online Disinfection

For online disinfection of the entire air humidification system, the additive chlorine dioxide if used. Continually adding small amounts of this additive ensures that the entire air humidification system, from the feed water to the atomizer nozzle, is kept perfectly hygienic at all times.
