- Bioremediation versus Generic Composting
Six months treatment cut 95% of priority PAH pollutants from coke oven effluent
Six months treatment cut 95% of priority PAH pollutants from coke oven effluent. Citadel Biocat+TM provided the bioremediation in situ of 150,000 cubic meters of contaminated soil at a decommissioned coke oven effluent lagoon. Several decades of steel production had created a residue of significant amounts of polycyclic aromatic hydrocarbons (PAH’s), along with soluble components such as cyanide, phenols and ammonia.
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 keeping valuable resources active. Technological advances in quality control have allowed specialized bioremediation...
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 be 390 and 17.22 mg/L, respectively, at an initial dye concentration of 750 mg/L and at pH 4.5 in 50 hours in a batch...
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 (MSM). Optimum pH values were 6 for PS and 8 for BW. All of the phenol present in the samples was mineralized regardless of its...
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 the shoreline to await transportation. As soon as the tide came in, it became apparent that oil, diesel, petrol had begun to seep from the broken...
