Microbial Community Structure of Activated Sludge
Activated sludge (AS) plays a crucial role in the treatment of domestic and industrial wastewater. AS is a biocenosis of microorganisms capable of degrading various pollutants, including organic compounds, toxicants, and xenobiotics. We performed 16S
Another case study for industrial wastewater treatment and recycling/reuse is the RO-based plant in Gujarat, which is used for treating the highly polluted wastewater consisting of various industrial effluent streams for recycling and reusing for industrial uses for its nonpotable purposes. The plant uses highly polluted wastewater from an effluent disposal channel into which several
Roles of ammonia-oxidizing bacteria in improving
Nitrification is a key reaction proceeds in two steps, the oxidation of ammonia (NH 4) to nitrate (NO 3-) via nitrite (NO 2) ().The ammonia oxidizers (AO) are the first and rate- limiting step of the nitrification process in a wide range of systems, and is catalyzed by two major microbial groups: AOB and ammonia-oxidizing archaea (AOA) (AOA not discussed in this review) through AMO as the key
The combined industrial wastewater was highly polluted with heavy metals (Cd, Ni, Hg and Pb), nutrients (phosphates, nutrients and ammonia) and COD. The constructed wetland with water hyacinth plant was capable of removing pollutants and the hydrophytes had shown its ability to survive in high concentration of nutrients with significant
Effect of Ammonia Nitrogen and Dissolved Organic Matter
Chlorine is a widely used disinfectant which prevents the spread of harmful pathogens when reusing wastewater, but harmful byproducts might be formed and cause adverse ecological and health effects. In this study, the potential effects of chlorination on the genotoxicity of different biologically treated wastewater samples were investigated using the umu test. For the first time, ammonia
The discharge of raw industrial wastewaters, specifically coking wastewater, represents a severe environmental problem. In this work, a phenol‐degrading aerobic strain isolated from a hydrocarbon contaminated site, Achromobacter sp. C‐1, was tested for degrading raw coking wastewater to explore its potential for use in biological treatment.. Initially, phenol degradation was reached after

Commercial Water Treatments Efficient wastewater processes are highly dependent on cultivating and maintaining a strong biological community which will break down and consume waste. As most wastewater plant managers and operators know, when the biological community is disrupted by toxins, chemicals, undissolved solids, fats, oils or greases
The Nitrogen Cycle - How Ammonia and Nitrite are
The treatments applied in lakes, ponds, rivers and streams will usually be different from those selected for industrial and municipal wastewater, although some rivers in China and the Philippines are more polluted than the average USA or EU wastewater treatment system and must be treated accordingly.

- What are the different types of polyacrylamide (PAM)?
- Explore the diverse applications of Polyacrylamide (PAM) types – Anionic, Cationic, and Non-ionic. Learn how these polymers are used in water treatment, wastewater treatment, and various industrial processes. Dive into the world of flocculants and polymer chemistry.
- How dangerous is polyacrylamide (PAM)?
- 4.1.1. Polyacrylamide (PAM) As PAM is extensively used in our daily lives, it is essential to be aware of its potential hazards. Studies have indicated that PAM exhibits low or non-toxicity to humans, primarily due to the large sizes of polymers, which restrict their ability to penetrate the skin.
- Can high molecular weight Pam be used for degradation?
- This paper provides a short review of current applications of high molecular weight PAM, including the potential for PAM degradation by chemical, mechanical, thermal, photolytic, and biological processes.
- What is polyacrylamide used for?
- One of the largest uses for polyacrylamide is to flocculate solids in a liquid. This process applies to water treatment, and processes like paper making and screen printing. Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer.
