Sample Applications

Initial situation before the installation Chemiepark Bitterfeld

In the pipe-line system for transportation of ground water hard sediments of inorganic material have formed up to 35 - 47 mm within a few months time. The pumps operate maximum 10 days after that they get exchanged and cleaned. When commissioning the Fluid-Liner® the piping system was not cleaned mechanically.


Initial situation biomass power plant Friedersdorf


The fermentation chamber is fed with corn silage. From small nozzles trickles the percolate onto the silage and wash out the organic material. The percolate is circulated and in order to fed the anaerobic process water storage (percolate storage) continuously with nutrients. The degradation of the organic acids into bio gas inside the percolate storage leads to an increased pH of the percolate often even above the neutral point. From the alkaline percolate, Struvite is created. Struvite is growing very fast inside pipelines, pumps, distributing nozzle, armatures and filters systems for solids. Short cleaning intervals reduce the availability of the system. An economic operation is not possible to achieve under this circumstances.

Situation before installation

Strong encrustations adhere in layers at the wall of the centrifuge. These encrustations affect not only the capacity and life expectancy of the centrifuge but also the interval of the hard facing. Even by the use of chemicals it is hard to avoid these depositions inside the centrifuge. Therefore the centrifuge is cleaned mechanically and chemically in intervals. The removed material is very solid


Situation before installation


Massive encrustations out of hardened fatty deposits in the entire pipe-lines (approx. 300 m). Expensive cleaning accomplished only with high pressure (milling) and modest success. The deposits could not be removed by using 120°C hot water and degreaser.


Situation before installation sewage-treatment plant Langenbrahm (Ruhrverband)

Hard deposits of calcium carbonate with a strong tressing and a high degree of cross-section contraction, almost up to total clogging. The wastewater pump is turned off by means of a pressure switch. The pipeline has been chemically cleaned before the installation of the protective induction system.
