Amphidrome, in the context of environmental and water treatment, refers to the oscillating flow pattern within a reactor. This dynamic movement is crucial for efficient biological treatment, enabling microorganisms to thrive and effectively remove contaminants from wastewater. Tetra Process Technologies, a leader in wastewater treatment solutions, utilizes this principle in their innovative Fixed-film Sequencing Batch Biological Filters (SBBF), offering a sustainable and efficient approach to water purification.
Traditional Wastewater Treatment vs. Fixed-film SBBFs
Conventional activated sludge systems rely on suspended microorganisms to degrade contaminants. However, this process can be inefficient, requiring large tanks and significant energy input. Fixed-film SBBFs, on the other hand, offer a more compact and energy-efficient solution. They utilize a biologically active medium, like bio-balls or other carrier materials, that provides a surface for microbial colonization. This film of microorganisms, known as biofilm, acts as a natural filter, effectively removing pollutants.
