SCHAFFHAUSEN, Switzerland (April 25, 2016) – Xylem Inc. has launched a new biogas support system, the Flygt BIS 1 biogas support system, specially adapted for the wall-mounting of submersible mixers in biogas digesters. The robust installation system is designed to ensure process optimization, reliability and safety as well as hold the mixer in place throughout its use. The system is easy to install and enables the operator to reduce installation time by up to 40 percent.* Because the digestion process in biogas can vary depending on the input material, adjusting the mixer’s position is critical to ensuring stability and preventing crust buildup or sedimentation. Xylem’s Flygt BIS-1 biogas support system, suitable for use with Flygt 4460 (1.3 meter propeller) and Flygt compact mixers, is fitted with a mixer guide bar that enables vertical and rotational movement (+/- 45 degrees) of the mixer from outside the closed digester, to direct thrust in the required direction. The durable BIS-1 support system is quick and easy to install, reducing system downtime and maintenance costs. The system is equipped with a patented guide bar connection which guarantees a secure and durable guide bar connection, minimizing vibration and maximizing system longevity. The system also features an intermediate support that enables a mixer to pass over an intermediate wall bracket smoothly without obstruction. “Biogas digesters have a sealed cover which means accessing the tank to change the mixer position is difficult," said Eilert Balssen, market manager Biogas and Agriculture for Xylem. "The Flygt BIS-1 biogas support system enables operators to move the mixer on the guide bar from the outside of the tank. With the introduction of this equipment to complement our high efficiency biogas mixers, Xylem offers a complete biogas digester mixing system. This will ensure perfect fit and performance.” Xylem has deep application knowledge supported by academic research, enabling its advanced mixing system to fulfill all mixing demands, while ensuring an optimal digestion process and maximising gas production. “Suitable for use with ‘new-build’ and existing biogas digesters, Xylem’s Flygt BIS-1 biogas support system is corrosion- and abrasion-resistant," Balssen said. "The BIS-1 support system has been engineered to support biogas plant operators by keeping system downtime and maintenance costs at the minimum level.” *According to Xylem tests
