Hot water foam procedures (briefly HWS called)
07.09.09
After only one and a half one year old development and Erprobungszeit the company IProS GmbH from Iserlohn presented its two types of device for the first time HWS 9 and HWS 26 on the demo park in iron oh the public. This was suitable outstanding for this, since application and the obtained results could be shown directly. Since the devices in close co-operation with a user were developed and tested, these are cut optimal to practice and permit a simple and a safe handling often within this range still with bad chemical means are worked, since simply effective alternatives are missing. An investigation of the biological Federal Institution for land and forestry from the year 2005/2006 proves that the hot water foam procedure and/or hot foam procedure represents the most effective chemistry-free procedure (see appendix). With the HWS procedure water is heated up on a temperature of nearly 100°C and applied with an application unit on the surface which can be worked on. There the hot water is covered with a separately produced and also foam carpet applied over the application unit. The foam has only an isolating and no chemical function and is fully biologically degradable. By the temperature, which is transported over the water as far as possible to the root, the cell walls and the protein of the game herbs burst coagulate, the celestial plant parts, upper parts of the root as ausgesähter seed die in such a way. In order to obtain an optimal lastingness, application is necessary, these can starting from the second year on 2-3 applications in the year be reduced in the first year 3-4 subject.
