endurance runner basic flizz® protects the energy and signal supply in snow and frost

A robust and weather-resistant system for year-round operation of the wastewater treatment plant

**
Over 300 plants with a total of over 9,000 metres of basic flizz® have already been equipped or retrofitted worldwide. For some time now, the focus has also been on export markets - Austria, for example. In addition, igus® has developed a new version of the system that uses a robust energy chain and can be installed on basins over 100 metres long. At the sewage treatment plant in Salzburg, the basic flizz® system manages the mobile energy and signalling supply for the scrapers in the clarifiers.

The secondary clarifier at the Radstadt wastewater treatment plant

Problem

The wastewater treatment plant of the Reinhalteverband Salzburger Ennstal treats the wastewater of around 12,500 residents and up to 120,000 ski tourists in the Sportwelt Amade with the member municipalities of Altenmarkt, Flachau and Radstadt and the Obertauern ski area.

The operation and in particular the transport routes and their supply lines are severely affected by the environmental conditions. Due to the amount of snow, it has so far been necessary to keep the lift tracks clear with a milling machine and to regularly replace the moving parts for the cable routing due to the climate and environmental conditions.

Solution

RHV has installed the basic flizz® system from igus® on the two basins, which are equipped with movable scrapers. It consists of an energy chain that is guided safely and smoothly in a weatherproof stainless steel housing. The compact and robust system is suitable for travel distances of up to 200 metres and was designed from the ground up for many years of trouble-free operation with minimal maintenance. RHV initially equipped the approximately 15 metre long grit chamber, and therefore a smaller tank, with the basic flizz® system. After the basic flizz® system had been in use on the grit chamber for a year without any incidents or signs of wear, the RHV fitters also retrofitted a second tank: the 46.5 metre long secondary clarifier. The floating moving end to compensate for the lateral offset of the scraper was also supplied by igus®.

Following the positive experience with the grit chamber, the 46.5 metre long secondary clarifier was also equipped with the energy supply system.

The path of the scraper with waste water from the sewage treatment plant

"During the Christmas period, the 12,500 residents can be joined by more than 120,000 tourists. However, the facility can cope with this because the figure of 125,000 represents the weekly average. (...) The maintenance effort is almost zero."

basic flizz® system

The basic flizz® is a system for mobile energy supply to scrapers, screens and other clarifiers and hydropower plants. A complete set consists of an energy chain, which is filled with the tried-and-tested chainflex® cable and guided safely and smoothly in a weatherproof stainless steel housing. With the developed moving arm and the smart plastic system EC.P for push-pull force detection, this set is a very good complete solution.
