Thirty-one mercury-resistant bacterial strains were isolated from the effluent discharge sites of the SIPCOT industrial area. Among them, only one strain (CASKS5) was selected for further investigation due to its high minimum inhibitory concentration of mercury and low antibiotic susceptibility. In accordance with 16S ribosomal RNA gene sequences, the strain CASKS5 was identified as Vibrio fluv...

The present work aimed to implement the reuse of water after treatment industrial effluents from a slaughterhouse and slaughterhouse, through projection fronts, aiming at socio-environmental sustainability in area influence activity, with following steps being carried out : preparation plan for implementation post-treatment effluent points; installation infrastructure redistribution treated on ...

the activated sludge process simply involves bringing together wastewater and a mixed culture of microorganisms under aerobic conditions. the system usually includes a secondary treatment given to the settled sewage, and requires an environment in which active microorganisms are maintained in intimate contact with wastewater in the presence of sufficient oxygen. in this study, the treatment of ...

development of an environmental friendly and cost-effective process for microbial degradation of caffeine to non-toxic compounds are promising to solve the problems of physiochemical extraction of caffeine in the treatment the caffeine containing agro-industrial effluents. thirteen bacterial strains, isolated from tea plantation soils in the north region of iran, were screened to show their abi...

Heavy metals pollution has become a more serious environmental problem in the last several decades as a result releasing toxic materials into the environment. Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical processes were used for the treatment of domestic, industrial and agricultural effluents. The commonly used conventional biological treatmen...

One of the most important and toxic heavy metals in wastewater is chromium. Cr (VI) is released from different industrial operations, including metallurgy, leather tanning, paint, textile industries, chemical manufacturing, pulp production, ore and petroleum refining, metal corrosion, electroplating products etc. Hexavalent chromium is toxic, carcinogenic, probably mutagenic and highly soluble....

Industrial wastes are considered critical factors for disturbing the natural environment. Composite effluents tainted with different heavy metals are major environmental pollutants of varied wetland ecosystems (Wong 2003). Spread over 12 500 ha, The East Calcutta Wetlands, a Ramsar site in West Bengal, India (lat 22°33 ́ –22°40 ́N, long 88°25 ́–88°35 ́E), receives industrial runoff from at least 60...

Chromium in the environment is considered as one of the most toxic elements probably next only to mercury and arsenic. It is acutely toxic, mutagenic and carcinogenic in the environment. Chromium contamination of soil and underground water due to industrial activities is a very serious problem in several parts of India covering Karnataka, Tamil Nadu, Andhra Pradesh etc. Functionally modified Ac...
