Microbial Wastewater Treatment | ScienceDirect
Microbial Wastewater Treatment focuses on the exploitation of microorganisms as decontaminating tools to treat polluted wastewater, a worldwide concern. Microorganism-based processes are seen as promising technologies to treat the ever-increasing problem of polluted wastewater.
Integration of Microbial Aggregates and Wastewater Treatment System. EBPR is widely applied in many WWTPs as an economical and sustainable method for P removal . Operation of EBPR relies on the enrichment of P by PAOs in the activated sludge system . Activated sludge can bring more PAO species to the assemblages.
Microbial aggregates in anaerobic wastewater treatment
Abstract. The phenomenon aggregation of anaerobic bacteria gives an opportunity to speed up the digestion rate during methanogenesis. The aggregates are mainly composed of methanogenic bacteria which convert acetate and H 2 /CO 2 into methane. Other bacteria are also included in the aggregates but their concentration is rather small.

Anaerobic bacteria in wastewater treatment plant
Anaerobic bacteria were widely present both in the sewage and in the air at workplaces in the wastewater treatment plant, reaching the highest concentrations in closed spaces. Some of the identified anaerobic bacteria belonged to the risk group 2 according to the EU Directive 2000/54/EC and should be treated as potentially harmful to the health
The stability of microbial aggregates is essential to the solid/liquid separation process in biological wastewater treatment systems (Seka and Verstraete, 2003). Stability is defined as the ability of microbial aggregates to resist hydrodynamic and mechanical shear ( Liao et al., 2002 , Mikkelsen and Keiding, 2002b , Sheng and Yu, 2006c ).
Response of syntrophic aggregates to the magnetite loss
1. Introduction. Anaerobic syntrophy is an essential intermediary step in the anaerobic conversion of organic matter into methane, where syntrophic microorganisms are linked tightly by the need of maintaining the exchanged metabolites at low concentrations (Morris et al., 2013).Actually, cooperative partners in natural environments often form multi-species aggregates.
Anaerobic wastewater treatment using granular sludge reactors is a developing technology, in which granular sludge is the core component. So far, around 900 anaerobic granular sludge units have been operated worldwide. Although intensive research attention has been given to anaerobic granules in the past 20 years, the mechanisms responsible for anaerobic granulation and the strategy of how to
Microbial interspecies interactions - PubMed Central (PMC)
Microbial aggregates, such as granules and biofilms, are frequently observed in methanogenic microbial communities, including those in methanogenic wastewater treatment systems (Skiadas et al., 2003). Anaerobic microbial metabolism can proceed close to thermodynamic limits.
methane via anaerobic process. Anaerobic treatment process is an appropriate technique for the bioconversion of dairy wastewater into biogas. 2.0 ANAEROBIC DIGESTION . Anaerobic digestion is a complex, natural, multi-stage process. It occurs in oxygen-free conditions and it is an engineered methanogenic process where organic matter
IJERPH | Free Full-Text | Bibliometric Analysis of Algal
In recent years, the algae-bacteria symbiotic system has played a significant role in the sustainable development of wastewater treatment. With the continuous expansion of research outputs, publications related to wastewater treatment via algal-bacterial consortia appear to be on the rise. Based on SCI-EXPANDED database, this study investigated the research activities and tendencies of algae

- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering . Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification .
- What is a cationic polyacrylamide synthesis?
- ... The main reaction of cationic polyacrylamide (PAM) synthesis is free radical copolymerization of acrylamide with the cationic monomer (Jiang and Zhu, 2014). The monomer containing positively charged functional groups used for synthesis of polymer applied in this study is dimethyldiallyl ammonium chloride (DMDAAC). ...
- What types of polyacrylamides are used in dewatering?
- Anionic, cationic, and nonionic polyacrylamides are used as coagulants and flocculants for the solid-liquid separations and enrichment of various minerals depending on the situation or application. The main processes that are used in dewatering include dewatering screens, sedimentation, filtering, and thermal drying.
