BIO-OXIDATION EFFLUENT TREATMENT SYSTEMS
Bio-oxidation effluent treatment systems leverage the power of aerobic biological processes to purify wastewater. Let's dive into how they operate:
Process Overview: These systems revolve around the aerobic oxidation of organic contaminants present in wastewater, utilizing a thriving community of microorganisms to do the heavy lifting.
Mechanism: In the presence of oxygen and essential nutrients, microorganisms break down complex organic matter, transforming it into simpler, less harmful substances. This natural process mimics the earth's own purification methods.
Applications: Predominantly used in secondary wastewater treatment, these systems are indispensable in reducing organic pollutants, making the water safer before it reaches its final discharge point.
Advantages: Not only are these systems cost-effective, but they also stand out for their sustainability. Their ability to adapt to varying loads of organic contaminants ensures consistent, reliable performance.
Variants: Innovative systems like Biorulli® take this process to the next level, employing specialized aerobic bacteria that accelerate the decay process, making wastewater treatment more effective and efficient.
These systems are a cornerstone of environmental protection, ensuring that wastewater meets strict regulatory standards before being safely discharged back into the ecosystem.
Biorulli® oxidation system: description and operation
The Biorulli® biodisc biological oxidation system is a sophisticated method that utilizes one or more rotating rollers to effectively break down organic matter in wastewater. As an aerobic biological treatment system, it relies heavily on oxygen and the activity of aerobic bacteria, which derive their nourishment from oxygen and play a pivotal role in the degradation of pollutants in both municipal and industrial wastewater.
Biodiscs, also known as “biological disc rotors” or “rotating biological contactors,” are at the heart of this system. In the Biorulli® setup, these biodiscs are mounted on a central shaft, with the number of discs varying depending on the specific model. Powered by a gear motor, the shaft rotates at a slow pace, typically between 1 and 5 revolutions per minute, depending on the model and the characteristics of the wastewater. The discs, constructed from propylene, are partially submerged—approximately 40 percent of their diameter—in a tank that channels the effluent to be treated.
The crux of the Biorulli® system lies in the interaction between the effluent and the rotating biodiscs. This contact fosters the growth of bacterial flora on the propylene surface of the discs. The continuous rotation of the discs allows the bacterial flora to alternate between two crucial phases: immersion in the sewage, where it absorbs the organic matter necessary for its sustenance, and exposure to air, where it becomes saturated with oxygen. This oxygen is a vital component of the biological oxidation process, enabling the bacteria to efficiently carry out the aerobic breakdown of pollutants. Once the bacterial flora completes its life cycle, it naturally detaches from the surface of the biodiscs in the form of easily sedimentable flakes, thus contributing to the purification process.
