One single tank, 2 models (1 gravity fed and 1 with a pump for low invert).
Tricel Maxus uses SAF technology. This technology treats wastewater through a four-stage process.
Stage 1: The settlement tank (septic tank/primary chamber)
The primary treatment occurs here. As the wastewater enters the Tricel Maxus system, the heavy solids are separated out and settle (forming a sludge on the tank’s base). Subsequently, the lighter solids, such as oils, fats or grease, float to the top of the wastewater and are retained within the settlement tank.
Stage 2: The buffer tank (buffer zone)
The incoming water load fluctuations are evened out here. The wastewater is fed forward into the treatment plant thanks to pumps located at the bottom of the buffer tank.
Stage 3: The biological treatment zone (Biozone)
The wastewater passes through, the submerged aerated filter (with a large surface area for the microbes) and is exposed to aeration.
The aeration is matched to the incoming flow to ensure efficient operation, thanks to the adjustments made by the control panel. Because of this, the system will not clog nor need any maintenance or chemicals.
Stage 4: The Clarifier
Here, the bio sludge from the treatment process settles out of the treated liquid. Thanks to the airlift pumps, the bio sludge from the tank’s base is recirculated back to the settlement tank. The fully treated liquid is now ready to discharge from the plant.
