A bioflocculant (MBFA18) was produced by Aspergillus niger (A18) using potato starch wastewater (PSW) as nutrients. The cultivation processes and flocculating treatment for PSW purification were systematically studied. The flocculating rate of the MBFA 18 achieved 90.06% (kaolin clay) under the optimal cultivation condition (PSW with 5950 mg/L COD, 20 g/L glucose, 0.2 g/L urea and without phosp...

We evaluated the bioflocculant production potential of an Actinobacteria, which was isolated from a freshwater environment in the Eastern Cape province of South Africa. 16S rDNA nucleotide sequencing analyses revealed that the actinobacteria belongs to the Brachybacterium genus, and the sequences were deposited in the GenBank as Brachybacterium sp. UFH, with accession number HQ537131. Optimum f...

Background & objectives: Pharmaceutical wastewater contains high concentrations of organic matter, high salt and difficult biodegradability, so it must be treated before discharge to the environment. In this study, it is aimed to evaluate the treatment of pharmaceutical wastewater (methadone feedstock and neutralized capecitabine) using chemical and biological methods. Methods: The laboratory ...

The waste water and industrial effluent-treatment requires both inorganic and organic flocculants. Among the organic type, polymeric flocculants (synthetic as well as natural) are preferred because of their low dosage, easy handling, inertness to pH changes, production of large cohesive flocs and versatile tailorability. The concern for environmental and ecological issues warrants the use of th...

BACKGROUND The identification of microorganisms with excellent flocculant-producing capability and optimization of the fermentation process are necessary for the wide-scale application of bioflocculants. Thus, we evaluated the flocculant-producing ability of a novel strain identified by the screening of marine bacteria, and we report for the first time the properties of the bioflocculant produc...

A field-scale data collection plan to monitor and evaluate the performance of a sediment basin design was developed and implemented using portable automatic stormwater samplers, flow modules, a rain gauge, and inflow weirs. The design configuration consisted of a skimmer as the primary dewatering device, three coir baffles installed inside the basin, polyacrylamide flocculant blocks and ditch c...

In the phosphate industry, thickening process is vital to increasing solid slurry concentration and recovering water that as clear possible. The performance of depends mainly on coagulation–flocculation effect. based flocculant agents concentrate particles: flotation washing plant rejects large flocs, which accelerate their sedimentation velocity. industry worldwide uses synthetical flocculants...

Mining activities are followed by mineral processing and wet beneficiation methods which generate a significant amount of tailings. Slime fractions discharged to the tailing ponds with associated process water this causes storage disposal difficulties creates severe environmental problems. Therefore, dewatering these tailings is necessary for both economic aspects. In study, flocculation behavi...
