  • Filter bed remediation - Case Study

    Biological filter beds usually consist of a mineral media over which effluent to be treated percolates. The media becomes host to a biomass which is grazed by a series of more complex organisms. If the growth of the biomass is greater than the rate at which the grazing occurs then the biomass film will accumulate in the bed. This will block the interstices of the media and restrict effluent ...

  • Enhanced Bio-Stimulation through Horizontal Wells

    Biosparging technology can be further enhanced when applied through Horizontal Remediation Wells. Since horizontal well systems typically have 4 to 10 times more screen footage in contact with the contaminated media than vertical systems, Horizontal Biosparge Wells can inject much greater volumes while maintaining the same low flow rates. This, in turn, leads to more rapid increases in dissolved ...

  • Meliadine Mine - Case Study

    This is a case study for a mine remote located in the Nothern region Nunavut of Canada. Meliadine is a gold mine where the camp wastewater is treated by a MBR technology. Probiosphere Bioremediation product Archaea supported the commissioning and startup of this project. This case study relates how Probiosphere Bacterial products can be trusted even after having gone under harsh environmental ...

  • Scientists scramble to understand the invisible creatures around us before it’s too late

    Researchers are uncovering the importance of the trillion-plus kinds of microbes on the planet — even as they worry the richness could be disappearing. In southwestern Africa, a dozen scientists dig in the dirt. In a week, they’ve transected 100 miles of shifting sand dunes and flat gravel plains across the Namib Desert, one of the driest places on Earth. They’ve ...

  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

  • Enhanced Bio-Remediation of Wastewater

    Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

  • Response surface modeling of bioremediation of acid black 52 dye using Aspergillus flavus

    Bioremediation is an efficient process to remove metals and dyes from solutions using different micro-organisms. In the present study, the efficiency of growing Aspergillus flavus (isolated from the effluent of an electroplating industry) to treat a synthetic solution of acid black 52 dye (a trivalent chromium complex dye) was investigated. Maximum removal of dye and chromium was observed to ...

  • Dual bioremediation of phenol and Cr(VI) by mixed microbial cultures in the presence of molasses

    Simultaneous phenol and Cr(VI) bioremoval by two different mixed cultures, from petroleum-contaminated soil (PS) and boron-contaminated wastewater (BW), was investigated in regard to different culture media, pH levels (6–8), initial phenol (25–100 mg/L) and Cr(VI) (15–50 mg/L) concentrations. The optimum medium was found to be mineral salt medium tested, which contained 1% (v/v) molasses ...

  • Nanobite Treated Contaminated Water – Fit to Drink! - Case study

    In 2010 the US Environmental Protection Agency, US Coast guard and BP Oil company invited Unirem Incorporated, the manufacturer of Nanobite Powder, to do an encapsulation test on crude oil polluted waters in the Gulf of Mexico. Nanobite Powder is the European trade name for a bio-remediation accelerator known in the USA as PRP (Petroleum Remediation Product). Nanobite Powder was ...

  • Nanobite bioremediates a Contaminated harbour - Case study

    When a hydrocarbon is spilled on water, it is very visible – floating on the surface, a blue green sheen clearly visible. When applied to an oil spill on water, Nanobite Liquid will not mix with the water and become diluted. Within a minute it attaches to the hydrocarbon, bonding with it and creating a matrix – an agglomerated gel- that remains on the surface and cannot sink, no ...

  • Hydrocarbon Bioremediation – Cleaning fuels & motor oil spills on water - Case Study

    Background Nanobite Products proved how effective they are in hydrocarbon bioremediation on water with the almost total remediation in one week of fuel spills from abandoned cars. Read on… On March 30 2006, in Black Sod Bay in County Mayo, between 45 and 50 cars were transported from a neighbouring island destined for scrap. They were deposited at low tide on ...

  • Nanobite remediates boyne river oil spill - Case study

    On the 6 September 2007, an oil spill from a fuel dump leaks into the beautiful Boyne River, County Louth, Ireland. Local wild fowl and their nesting areas are endangered, as is the local water supply. The coastguards deploy conventional booms to contain the spill but decide against the use of conventional chemical detergents because of the obvious damage to flora and fauna. ...

  • Nanobite Protects Sea Life from Oil Pollution - Case Study

    Oil pollution at sea can have devastating consequences for sea life – especially seabirds. When their feathers get covered in crude oil, they are unable to fly and death is almost certain. ...

  • Bioremediation of Antifreeze lakes at Airports - Case study

    Ethylene glycol (antifreeze), used to de-ice airplanes, is generally stored in lakes and holding ponds in or around airports. Poisonous to human beings and animal life if ingested, Nanobite can completely bioremediate this hydrocarbon in situ using a combination of liquid and powder ...

  • From urban municipalities to polar bioremediation: the characterisation and contribution of biogenic minerals for water treatment

    Minerals of biological origin have shown significant potential for the separation of contaminants from water worldwide. This study details the contribution of biologically derived minerals to water treatment operations, with a focus on filtration media from urban municipalities and remote cold regions. The results support biofilm-embedded iron and manganese to be the building blocks of ...
