The intelligent FinnFlow® system takes advantage of natural water flow to create a reliable, energy-saving and low maintenance system. The system suits all tanks requiring surface scum removal. The requirement is that the FinnFlow® collector can be connected to a removal pipe or a channel for cleaned water in order to generate a flow.
The most common applications of the FinnFlow® system are preliminary and secondary sedimentation tanks in which scraper flights transfer the sludge close to the FinnFlow® collector. The FinnFlow® system collects surface scum to the collector by regulating the water levels. Since it uses a continuous flow, treated clean water comes along with the surface scum.
The system’s intelligent technology directs surface scum to a smaller scum collection box located inside the collector, while transferring the treated water to a removal pipe for clean water via a pipe located at the bottom of the collector. Water movement is regulated at each stage at different water levels.
PREVENT THE ODOR DISORDER
Finnchain Solar Covers are designed to prevent odors from the tank. For this reason, the roof modules are connected closely and if necessary, activated charcoal filters can be used for deaeration. At the same time this also prevents harmful gases from entering the environment.
FC-SOL 1500 cover with solar panels
Finnchain’s Solar Covers also allow use of renewable energy, as cover modules can be equipped with solar panels.
The surface area of the tank can then be utilized for renewable energy utilization.
Since covers prevent sunlight from entering the water, amount of algae is decreasing. Covers also prevent snow, rain or sand dust entering the tank.

OWN TEST TANK FOR PRODUCT DEVELOPMENT
Finnchain constantly develops its products. Product development requires frequent product testing, which is why we built our own test tank, 25 metres in diameter. During this extensive product development process, we have upgraded our scraper structurally and discovered the best possible raw material compositions for different components. We have upgraded almost all of our components during the process. Our greatest innovations include the patented conveyor chain and driving wheel systems, new idle wheels and tightening shafts, lighter surface sludge scraper, more efficient surface sludge removal, self-steering bottom scraper wheels and the use of two motors in large tanks.

PATENTED SURFACE SCUM REMOVAL
SURFACE SCUM REMOVAL
The scraper flight in the Finnchain system, moving at the surface of the tank, transfers the floating scum to the scum collection box on the side wall of the tank. The efficiency of the scum removal is based on scum gates located in the scum collection box. The scum gates open up when the scraper flight approaches the scum collection box, causing a water flow which enables the efficient collection of the scum. The water flow transfers the surface scum to a removal pipe for further treatment, and prevents freezing during winter. The opening of the scum gates can be adjusted, which enables more efficient removal of the surface scum.
