Sewage treatment plants with intelligent monitoring

• What was needed: basic flizz® energy chain system, condition monitoring EC.P
• Requirements: robust and durable energy chain, avoidance of total failures due to unnoticed malfunctions
• Industry: Wastewater treatment plants
• Success for the customer: The advantages of the basic flizz® energy chain used are its modular design and protection against wind and weather. Thanks to the 24/7 status monitoring of the chain, the system switches off in the event of faults to prevent a total failure. This saves the operator considerable time and money.

In sewage treatment plants, energy chains are in operation around the clock, 365 days a year. Despite this continuous load, downtimes of the pipework systems should always be avoided, which requires particularly robust and durable systems and components. But chain guidance alone is often not enough. This is because most sewage treatment plants run for a large part of the time without any human presence. Therefore, malfunctions and possible misbehaviour sometimes remain undetected for hours. Although the chains move at a very slow speed, a malfunction usually leads to a complete total loss. This total loss of the cable carrier system leads to significantly higher costs than a shutdown lasting several hours, where the system can be put back into operation after a short maintenance period. Without human supervision, the corrective element is missing.

The use of a basic flizz® energy chain system is very suitable for most rectangular clarifiers. The advantage of the e-chain® is its modular design and protection from wind and weather. The basic flizz® system can be mounted either directly on the tank wall or on the ground along the tank.
In applications where constant monitoring of the system is required, the energy chain system is combined with condition monitoring in the form of an EC.P sensor (EC = e-chain P = pullforce). This sensor, which is mounted on the floating moving end of the e-chain®, continuously measures the force required by the system to move the energy supply. If these forces change due to external influences such as ice, an animal or a tool forgotten during maintenance, the sensor recognises this change and switches the system off - without any human intervention.
This prevents expensive consequential damage to the energy supply.
