“…The colored water may stain textile and fixtures that can cause permanent damage on industrial boilers, equipment and tools which could lead to high consumption of energy because of the insulation caused by minerals (like Fe and Mn) present in water and hence reduces efficiency and life of the equipment [34,35]. Both Fe and Mn produce odor and offensive taste that may affect animal intake [36] and their oxides play important role in the soil for fixing trace elements such as Co, Ni as well as pollutants like Pb [37].…”

ABSTRACT. In the present study, laser-induced breakdown spectroscopy (LIBS) has been applied for the determination of levels of Cr, Mn and Fe in sediment samples and the results have been compared with that of flame-atomic absorption spectroscopy (F-AAS). Fourteen sediment samples were collected from Tinishu Akaki River (TAR), Addis Ababa, Ethiopia. Pellets of 24 mm in diameter and 3−5 mm in thickness were prepared using a manual hydraulic press under a pressure of 8000 psi by mixing finely ground sediment samples with boric acid. The concentrations of Cr, Mn and Fe were successfully determined by Q-switched Nd:YAG laser at 1064 nm. Quantification of these metals was conducted against certified reference materials of sediments and soils. The LIBS results for the elements varied from 0.060-0.707 mg/g for Cr, 0.895-3.64 mg/g for Mn and 26.9-71.8 mg/g for Fe. The F-AAS results varied from 0.061-1.37 mg/g for Cr, 1.24-4.46 mg/g for Mn and 49.0-83.3 mg/g for Fe. TAR was found to be heavily polluted with Cr.

“…Therefore, development of newly designed primer for specific detection of the 16S rRNA gene of Leptothrix would be required to analyze the population of Leptothrix in Joyo bacterial consortia using real-time PCR. Leptothrix had been thought as a principal MnOB in the biological filtration system, and used as a model MnOB for laboratory-scale studies for biological removal of Fe and Mn from water (Hope and Bott, 2004;Katsoyiannis and Zouboulis, 2004;Burger et al, 2008b). However, contribution of the other MnOB, such as Hyphomicrobium, for the Mn oxidation would be considered.…”

Bacterial diversity of the microbial consortia in a biological filtration plant for the elimination of iron (Fe) and manganese (Mn) from groundwater in Joyo City, Kyoto, Japan, was studied. PCR-based denaturing gradient gel electrophoresis (DGGE) analysis of bacterial 16S ribosomal RNA (rRNA) genes represented at least 15 signals, and nucleotide sequences of the dominant fragments showed similarities to Gallionella and Nitrospira. Phylogenetic analysis using the obtained nucleotide sequences of the 16S rRNA gene clone library showed the presence of the bacteria related to Hyphomicrobium, Gallionella, and Sideroxydans, which are supposed to be involved in Fe and Mn removal. In contrast, no 16S rRNA gene clone affiliated with the genus Leptothrix, which have been regarded as a major Fe-and Mn-oxidizer in biological filtration system, was observed. Though a large number of 16S rRNA gene clones closely related to Nitrospira was obtained, no clone showed high sequence similarity to known ammonium oxidizing bacteria (AOB). However, PCR-amplification of the ammonia monooxigenase gene (amoA) of AOB and ammonia oxidizing archaea (AOA) indicated the presence of both AOB and AOA in this biological filtration plant.

“…When raw water such as river water flows through the BCF column, ammonia and dissolved organic matter (DOM), including those that produce foul smell, are oxidized and removed by the microorganisms attached to the filter media [3]. Additionally, iron and manganese are also oxidized to insoluble metal oxides and removed by autotrophic bacteria [4]. Microorganisms in the BCF trap the oxidized matter, thereby restricting its flow to the next process (MF or UF).…”

Membrane fouling is a serious problem in drinking water treatment systems. Biological contact filters (BCFs) are often used as a pretreatment to remove ammonia, dissolved organic matter (DOM), and metal ions such as iron and manganese. In this study, the effect of BCF as a pretreatment for membrane fouling was evaluated using a laboratory-scale mini module consisting of a mini BCF column and a mini MF column. Initially, it was confirmed that the main foulant was a biopolymer (at low concentration) in the raw water. Subsequently, the biopolymer concentrations in the BCF influent and effluent were measured with the excitation emission matrix (EEM) fluorescence spectroscopy and the liquid chromatograph organic carbon detector (LC-OCD). The fouling potential of the BCF influent and effluent was also measured to evaluate MF membrane fouling rate. The results demonstrate that application of the BCF reduced the biopolymer concentration of the effluent and reduced membrane fouling. The effect of BCF was also established in an actual drinking water treatment plant. It was found that optimizing the contact time of raw water with the BCF was crucial to reduce membrane fouling.
