Flocculating performance of a bioflocculant produced by Arthrobacter humicola in sewage waste water treatment
BACKGROUND The discharge of poorly treated effluents into the environment has far reaching, consequential impacts on human and aquatic life forms. Thus, we evaluated the flocculating efficiency of our test bioflocculant and we report for the first time the ability of the biopolymeric flocculant produced by Arthrobacter humicola in the treatment of sewage wastewater. This strain was isolated fro...
متن کاملFlocculating Properties of a Bioflocculant Produced by Bacillus sp. Isolated from a Marine Environment in South Africa
Flocculation is a process whereby chemicals (flocculants) stimulate aggregation of colloids and other suspended particles in a suspension to form floc. This is different from precipitation, because prior to flocculation, colloids are suspended in a liquid and not completely dissolved in a solution.1 Flocculation finds usefulness in many fields such as wastewater treatment, downstream processing...
متن کاملStudies on Bioflocculant Production by Arthrobacter sp. Raats, a Freshwater Bacteria Isolated from Tyume River, South Africa
A bioflocculant-producing bacteria was isolated from Tyume River in the Eastern Cape Province, South Africa and identified by 16S rRNA gene nucleotide sequence to have 91% similarity to Arthrobacter sp. 5J12A, and the nucleotide sequence was deposited in GenBank as Arthrobacter sp. Raats (accession number HQ875723). The bacteria produced an extracellular bioflocculant when grown aerobically in ...
متن کاملTreatment of Textile Waste Water with Organoclay
In this study a sample of bentonite obtained from Semnan mines, was modified by a surfactant to prepare an organoclay with high surface area. BET analysis showed that the modification increased its surface significantly. The prepared sorbent was used for removal of dyes and other organic pollutants from a waste water obtained from Ekbatan textile company. Adsorption was studied in ...
متن کاملBioremediation of Sewage Waste Water using Rhodobacter Capsulatus
Rhodobacter capsulatus is a species of purple bacteria, a group of bacteria that can obtain energy through photosynthesis. It has diverse metabolism and therefore it can be used as a potent bioremedial agent. An attempt was therefore made to evaluate its effectiveness in improving the physico-chemical quality of water contaminated with sewage waste. Certain parameters for the assessment of qual...
