Biogreen Waste Water Treatment System

The Biogreen Wastewater Treatment System Scaled up to 50 pe. As is required by the certification procedure the process was tested at the lowest population equivalent. For larger systems all elements of the process are scaled up pro-rata. For example in the 8 PE system the volume of the Primary Settlement is twice that used in the 4 PE version and likewise for the volume of the Aeration Chamber and the area of the secondary clarifier. This ensures the validity of the certified process is retained for all products within the range up to a PE of 50.
