CaCO3 is one of the most common emitter clogging factors among chemical precipitates in drip irrigation systems. Continuous acid application as a classical approach to prevent CaCO3 clogging can be tricky, expensive and hazardous for soil. In order to develop an environmentally friendly method to address the problem, two bacterial strains, one renowned as a PGPR and the other having extensive CaCO3 dissolving capacity, were used in treatments of artificially clogged drip irrigation emitters. Results showed the flow rates of clogged emitters significantly increased in drip lines which were treated with bacterial suspensions but no increase was observed in control drip lines which were treated with sterile nutrient broth. Furthermore, scanning electron and florescence microscopies were used to examine residual CaCO3 precipitates. Thus, in consideration of its extensively studied PGPR characteristics, microbial treatment with Bacillus subtilis OSU-142 was shown to be promising for field applications as a novel and environmentally friendly treatment for clogged emitters of drip irrigation systems.

Overview of microbes based fabricated biogenic nanoparticles for water and wastewater treatment Ali, Imran; Peng, Changsheng; Khan, Zahid M.; Naz, Iffat; Sultan, Muhammad; Ali, Mohsin; Abbasi, Irfan A.; Islam, Tariqul; Ye, Tong (Elsevier BV, 2019-01-15) Treatment of toxic and emerging pollutants (T&EPs) is increasing the threats to the survival of conventional wastewater treatment (WWTs) technologies. The high installation and operational costs of advanced treatment technologies have shifted the research interest to the development of economical and reliable technology for management of T&EPs. Thus, recently biogenic nanoparticles (BNPs) fabricated using microbes/microorganisms are getting tremendous research interest due to their unique properties (i.e. h...
Diversity and community analysis of ammonia oxidizing bacteria in a streambed surrounding an artificial dam Murdoch, Robert Waller; Staniec, Andria Costello (Elsevier BV, 2013-09-30) The degree to which small natural dams affect the native bacterial nitrogen cycling community was explored by molecular methods. The identities and relative abundances of ammonia oxidizing bacteria in the sediment surrounding an artificial dam both at the surface and in the hyporheic zone were characterized. Analyses were performed using tRFLP of the conserved amoA gene using a semi-nested degenerate PCR approach. Additionally, an amoA gene library was constructed to characterize the most dominant sediment ...
Encapsulated green magnetic nanoparticles for the removal of toxic Pb2+ and Cd2+ from water: Development, characterization and application Ali, Imran; Peng, Changsheng; Lin, Dichu; Saroj, Devendra P.; Naz, Iffat; Khan, Zahid M.; Sultan, Muhammad; Ali, Mohsin (Elsevier BV, 2019-03-15) Current research is based on an innovative approach of the fabrication of encapsulated sustainable, green, phytogenic magnetic nanoparticles (PMNPs), to inhibit the generation of secondary pollutants (Iron/Fe degrees) during water treatment applications. These novel bio-magnetic membrane capsules (BMMCs) were prepared using twostep titration gel crosslink method, with polyvinyl alcohol and sodium alginate matrix as the model encapsulating materials to eliminate potentially toxic metals (Pb2+ and Cd2+) from ...
Merits of ozonation and catalytic ozonation pre-treatment in the algal treatment of pulp and paper mill effluents Balcioglu, I. Akmehmet; Tarlan, E.; Kivilcimdan, C.; Sacan, M. Tuerker (Elsevier BV, 2007-12-01) Since the performance of algal treatment for pulp mill effluent decreases with increasing color intensity and AOX content, which mainly originate from the chlorine bleaching of Kraft pulp, the separated CEH bleaching effluent was pre-treated by both the conventional and the heterogeneous catalytic ozonation processes. An increase in the BOD5/COD, ratio from 0.11 to 0.28 and 87% color abatement in terms of Pt-Co were achieved by catalytic ozonation, which had the best treatment performance. Biodegradability ...
A Laboratory Column Investigation for the Treatment of Cr(VI) with Zero-Valent Iron Uyusur, Burcu; Ünlü, Kahraman (Mary Ann Liebert Inc, 2009-02-01) Permeable reactive barrier (PRB) technology is commonly placed in the list of options for groundwater remediation at hazardous waste sites, where Cr(VI) treatment in groundwater has been a concern more than any other inorganic contaminants. The objective of this study was to investigate the effectiveness and longevity of Cr(VI) removal with zero-valent iron based PRBs. The main focus was on two parameters affecting the performance of Cr(VI) removal with PRBs: (1) amount of reactive media and (2) groundwater...
