Biological treatment of wastewater is used to lower the organic load of soluble organic compounds.
Our aerobic treatment process uses microbes to decompose organic compounds in the presence of oxygen and use the liberated energy for reproduction and growth. On our specially constructed bio-tower, waste water is trickled over a fixed media on which grows a layer of microbes, which effect the degradation of BOD.
Waste streams that can be treated on our biological treatment plant include:
- Alcohols, (e.g. IPA)
- Sugars (e.g. sucrose)
- Organic Acids (e.g. acetic acid)
- Biodegradable aqueous wastewaters
The primary aim of the biological treatment process is the reduction of BOD and COD in incoming wastewaters, such that the treated effluent meets the requirements of our discharge license. Organic compounds are progressively degraded to simpler molecules by the bacteria, thus reducing the organic loading of the wastewater and rendering it suitable for discharge. This type of treatment process is used in most towns and cities for the treatment of municipal (sewage) wastewater, and is the most effective means of treating biodegradable effluents.
If you are unsure as to whether a particular wastewater is suitable for biological treatment, Enva can carry out laboratory studies to assess this. This ensures that the right treatment solution is selected for each customer’s individual needs.
