-Reduction and prevention of biofilm re-formation
-Ideally suited for evaporative cooling systems, air scrubbers and humidifying units in ventilation and air conditioning equipment
Frankfurt/ Lingen, 14th March 2017– emcoKlima presented natural water processing with the "emconarewa" system as a further competency field at the ISH 2017 in Frankfurt. Close interlinking with the distribution company emco Water, which was set up during the past year, and the many different areas of operation for the patented technology in ventilation and air conditioning technology are at the forefront here. The innovative system uses natural operating principles – shear forces, frictions, cavitation, low pressure and cold oxidation – to verifiably reduce microbiological loads in, for example, evaporative cooling systems, air scrubbers or humidifying units in ventilation and air conditioning systems without the use of any chemical additives whatsoever. Furthermore, the biosurfactants set free by the annihilation of germs bring about a reduction of surface tension by about 40 per cent and so improve the flow and wetting capability of the water. This has a positive effect, amongst other things, on the effectiveness of cooling and air humidifying processes. Also biofilms in pipework and cooling circuits are gradually broken down and their re-formation lastingly prevented. The compact water processing system is available in three sizes and nine performance classes ranging from 2.5 to 51 m³/h, optionally in a stainless steel or aluminium housing, and can be integrated into open and closed circuits.
Accordingly, the system is ideally suited for cooling systems in which water is trickled or sprayed or can otherwise come into contact with the atmosphere – and so also specially for evaporative cooling systems forming the subject of the present VDI 2047 Sheet 2 – in order to effectively prevent the risk of microbiological contamination by legionella. Since a gradual breakdown of the biofilm also takes place in the cooling water circuit during water processing, this measure is one which is effective in the long term. Moreover, the cooling capacity of the systems increases because of the improved wetting capability of the water. Here the lower surface tension after trickling results in improved heat exchange in the area of the filling material or the heat exchanger. The same happens on contact with the air through fine atomisation of the water. At the same time the fine mist washes organic material out of the air better. These materials return again to the water circuit with the mist drops and are destroyed during processing.
Consequently air scrubbers or humidifying units in ventilation and air conditioning equipment represent a further area of use for natural water processing. They enable germ loads in the air to be kept within the limit values specified in accordance with VDI 6022 and the EU air quality directive 2008/50/EG at a comparatively low cost. The technology has already been successfully demonstrating its effectiveness, for example, at Frankfurt am Main Airport for several years now. There the system starts up once an hour for five minutes while the humidifying unit of the ventilation system is idling, in order to process accordingly the water standing ready in a tank. The great effectiveness of the system has recently also been verified by an independent study conducted at Münster’s University of Applied Sciences. There at present a further study is being conducted specifically into the prevention of contamination by legionella.
The technology thus also offers an equally effective but markedly more environmentally-friendly alternative to water processing using chlorine or other chemicals. Thus in flowing water bodies strong currents have a self-cleaning effect, germ-laden water is highly accelerated under high pressure in a reaction vessel and deflected against its original direction of movement. Here high shear forces and friction are set up, which destroy most of the organisms and microbiological constituents. At the same time cavitation occurs, which, like a vacuum generated by a Venturi tube, cause the remaining microorganisms to burst open and die. Further, oxygen can be added to the water through a special valve so that the bacteria fragments are broken down naturally by cold oxidation. Here biosurfactants are set free that bring about both lasting removal of the biofilm and reduction of the surface tension of the water.
