Abstract:
Chemical and biological leachings of As and metals from sewage sludge were carried out using a batch reactor under an aerobic condition. Addition of phosphate to the sludge was ineffective for the elution of As from the sludge at neutral pH. Akalization of the sludge to pH 11 eluted sufficient As, whereas it was ineffective for Al, Cd, Mn and Zn. Furthermore, the effectiveness of ferric sulfate and iron oxidizing bacteria was investigated under acidic conditions. The application of ferric iron and/or iron oxidizing bacteria eluted As from the sludge more effectively than that of sulfuric acid

Abstract:
Ecological floating beds, with their compact footprint and mobility, offer a promising solution for sustainable surface water remediation in rural areas. However, low removal efficiency and instability still limit its application. In this study, iron–carbon-based fillers were integrated into ecological floating beds to investigate their impact and mechanisms in removing pollutants, including carbon, nitrogen, phosphorus, and heavy metals. Results indicate that all five fillers (activated carbon, iron–carbon fillers, sponge iron, activated carbon + iron–carbon fillers, and activated carbon + sp

The presence of small amounts of iron (>0.013% Fe) in sand creates problems in the manufacture of high quality glass. Removal by hot sulphuric acid is possible, but creates environmental problems, and is costly. Hence organic acids such as oxalic have been investigated since they are effective in removing iron, and can be degraded anaerobically. The aim of this work was to identify key intermediates in the anaerobic degradation of oxalate in an upflow anaerobic sludge blanket reactor (UASB) which was removing iron from solution in the sulphide form, and to determine the bacterial specie

AbstractThe use of the biological method is promising for treating underground waters from iron compounds. Iron bacteria used in the process are widely spread in weak acidic and neutral underground waters containing iron ions (II), dissolved carbon dioxide and minimum concentrations of oxygen. The relevant direction of present-day biotechnology is the use of iron bacteria for treating underground waters. The goal of this research is to compare the efficiency of using the biological method for treating underground iron containing weak acidic and neutral waters under different conditions. As the

Abstract:
Sulfate reducing bacteria (SRB) and iron reducing bacteria (IRB) that widely exist in water supply networks are the main microorganisms leading to metal corrosion in pipelines. Chlorine is widely used in drinking water supply systems. The concentration of chlorine with SRB declined rapidly after 10 mins and reached 0 mg/L finally whereas it decreased more slowly with IRB. If the concentration of chlorine is lower than 0.2mg/L, IRB cannot be sterilized. It indicates that at the end of water pipes where the concentration of chlorine is required to be 0.05mg/L, chlorine is not effective since the

Abstract The production of hydrogen sulfide within oilfield systems can result in severe operational and health and safety issues. Hydrogen sulfide can be produced by both abiotic (chemical) or biotic (microbiological) mechanisms. Biotically produced hydrogen sulfide is caused by the proliferation of sulfate reducing bacteria (SRB) and successful treatment programmes need to target both the causative organism and remove or mitigate the secondary effects of SRB activity, i.e. iron sulfide deposition and particulate stabilised emulsions.

Abstract “Schmoo” is the smelly, black goo found coating the inside of produced water piping at the Prudhoe Bay oil field; it is essentially oil-coated particulates of iron sulfide. Layers more than 1” thick have been found in some injection well lines. Schmoo causes several significant problems: It can plug injection wells, requiring expensive well work to unplug the wells. Worse, colonies of bacteria erow under heavy layers of schmoo, corroding pits in the pipe, and necessitating very expensive repairs. These problems prompted the development of a novel dispersant to remove the schmoo. The n

Abstract Chemical and oxidative biocides are designed to sanitize water by reducing aerobic and anaerobic bacterial populations in the fresh, brackish and reclaimed source waters. These biocides are used extensively in high-rate fracture stimulations to reduce formation damage, chemical degradation, biogenic H2S and microbial induced corrosion (MIC). Oxidative biocides work by removing electrons from the cell wall of aerobic and anaerobic bacteria. The same electron transfer mechanism can be detrimental to surface equipment.
