Bioaugmentation: An Emerging Strategy of Industrial Wastewater Treatment for Reuse and Discharge Article (PDF Available) in International Journal of Environmental Research and Public Health 13(9
Bioaugmentation (the process of adding selected strains/mixed cultures to wastewater reactors to improve the catabolism of specific compounds, e.g. refractory organics, or overall COD) is a promising technique to solve practical problems in wastewater treatment plants, and enhance removal efficiency.

Treating India's wastewater: why inaction is no longer an
Another estimates India's total water and wastewater treatment market alone is worth about $420m, growing annually by about 18%. But the government's twelfth five year plan (2012-2017) states that
By using a 2-L synthetic wastewater reactor that contained COD (3200 mg/L), nicotine (1 g/L), and AS from a wastewater treatment plant, Wang et al. tested the effect of bioaugmentation with Acinetobacter sp. on the biodegradation of nicotine. The results showed a significant increase in nicotine removal from ~10% in the control reactor to 98%
Recent Advancement on Bioaugmentation Strategies
Thus, PIWW treatment technologies are focused on three purposes, i.e., reduction in water usage, treatment of effluent, and recycling of water and other catalyst. In the last two decades, different types of physical–chemical treatment systems are established as secondary and tertiary stage wastewater treatment systems.
Wastewater treatment plants in the pulp and paper industry have unique challenges due to the large volumes of water used and these high concentrations of organics resulting in the wastewater. Success or failure of the treatment process depends on the ability of microorganisms to tolerate often harsh conditions and maintain efficient COD
Bio-Augmentation Technology in Textile Mill Wastewater
The studies were carried out using the wastewater sample collected from ETP of Textile Mill at Ganganagar near Kolkata, India during September 2006-February 2007. The influent and effluent characteristics before and after Bio-augmentation process are shown in Table 2 .

Anaerobic domestic wastewater treatment could be a net energy producer. Another significant advantage is that the quantity of digested sludge resulting from anaerobic treatment is much less than with aerobic treatment (Figure 2b), another highly significant cost as well as energy benefit.
- Is polyacrylamide contaminated with acrylamide?
- Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food.
- Is acrylamide a copolymer?
- Even though these products are often called 'polyacrylamide', many are actually copolymers of acrylamide and one or more other species, such as an acrylic acid or a salt thereof. These copolymers have modified wetting and swellability.
- What is a polyacrylamide gel?
- The polyacrylamide gel is a polymer matrix of acrylamide cross-linked by N,N-methylene-bis-acrylamide (known as bis-acrylamide) as the result of a polymerization reaction between them, induced by tetramethylenediamine (known as TEMED) and carried out by ammonium persulfate (known as APS).
- Is polyacrylamide a powder or liquid?
- Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer. Even though these products are often called 'polyacrylamide', many are actually copolymers of acrylamide and one or more other species, such as an acrylic acid or a salt thereof.
