The Command valve allows the force to drop, and the air sparger at The underside from the tank maximises microbubble formation and evenly distributes the flow.
Due to the Highly developed FADAR® technology, our equipment generates a stream of micro-air bubbles that adhere to the flocs, elevating them towards the surface area the place a scraper procedure gets rid of the sludge mattress created on the hopper that collects the sludge, achieving a reduction in total suspended solids by as much as ninety%, reducing COD, and obtaining a sludge dryness of all around six%.
A sludge elimination drain or channel at The underside of the tank eliminates any heavier solids which will settle Regardless of the constant upward press from the bubbles.
