How does it work
Our bio unit is configured as a downward flow, diverted input unit with longitudinal air delivery, to manage water flow around the chamber, maximising the active volume for biofiltration.
Incoming water at the top will have a tendency to “track” diagonally or straight down to the outlet, the path of “least resistance”. By making it interact with the air from the bottom of the tank, this water flow is disrupted and forced back upwards. If part of the incoming flow is diverted towards the centre of the tank, the water is forced into the area where the air is rising, enhancing this flow disruption and pushing the water out to the sides. As the water is pushed sideways at the surface of the unit, it has no choice but to travel downwards when it hits the side. The bottom of the chamber is curved, helping that downward flow turn into a circulatory movement. When reaching the air bar right at the bottom of the unit, the water is forced back up to repeat the circulation until it exits out of the far end. This curved bottom also eliminates any corners where debris may accumulate.
