Solution: DRAUSY Professional linear distribution of active ingredients

Category: Icon

Company/Submitter: Drausy GmbH / Cordula Pinna-Weth (Jäger)

Design:

DRAUSY Professional is a pressure-equalising linear tubing system that conveys the same discharge volume of gases or liquids over long distances and differences in height.
The system has established itself primarily in the treatment of stagnant water: Targeted basic aeration through the microinvasive distribution of oxygen leads to the long retention time of the atmospheric oxygen. Since the treatment is carried out at depth, the entire water body is included. The settlement of very fine oxygen bubbles changes the milieu, sludge is decomposed and there is a clear improvement in the quality of the entire water body. 
A worldwide patent application for the system was filed in the early 1990s and it has been continuously developed over the past twenty years. The manufacturer promises a service life of around 50 years for the material properties. The system is environmentally biotechnological and does not use any chemicals: A gentle, environmentally friendly measure to improve the quality of water bodies, which also reduces odours and prevents siltation due to sludge formation.

Long-term and Sustainable Management of Artificial Water Bodies By comprehensive micro-invasive aeration along the entire watercourse surface, the environment is transformed from oxygen-poor to oxygen-rich. The Results are a degradation of organic matter, a permanent binding of pollutants and nutrients to the sediment, an algae/cyanobacteria avoidance, an oxygen enrichment and a reduction of harmful greenhouse gases.

Some like ice - some don't. For fish in shallow waters, ice can become a problem. The aquatic habitat of a pond is a versatile habitat that is influenced by many factors. Leaf litter and fish food or the water filling itself form the nutrient basis - they are the basis for plant growth, but on the other hand they also form organic sludge layers at the bottom of the pond. If it freezes for a very long time, as it did this winter, and there is also - obscuring - snow on the ice, it can become critical for still waters, plants and organic matter decompose with considerable oxygen consumption. As long as the pond gets enough light, plants produce a lot of oxygen under ice during the day through photosynthesis, even in winter. If there is no light in the pond, the previously green parts of the plants also consume additional oxygen through decomposition. For the fish in the pond, oxygen then becomes scarce; carp die if the oxygen level is permanently below 2 mg/l, and trout die if the oxygen level is permanently below 3 mg/l. The problem of oxygen deficiency can be further aggravated - as can be seen in the picture, fish die in droves if the living conditions are not suitable. With linear basic aeration, lakes and ponds are efficiently supplied with air bubbles that remain in the water for a long time: they not only release oxygen to the fish, but also continuously break down organic sludge, thus preventing the formation of gas that is toxic to fish.
