“…However, doubling the HRT to 7-10 days has been suggested for indirect organic substrate, to allow sufficient time for microbial growth (Alvarez, Crespo, & Mattiasson, 2007;Chang, Shin, & Kim, 2000;Gonçalves, Oliveira Mello, & Costa, 2008).…”

“…These sources are readily utilized by SRB, yielding high H 2 S in a short amount of time. However, these sources are expensive and require a large expenditure on long-term operation which would put a strain on operational costs.There have been several published reports that utilize various organic solid wastes as the carbon source for SRB; these include wood dust, oak chips and sludge from a wastepaper recycling plant (Goncalves, Mello, & da Costa, 2007). These waste materials have the advantage of being able to sustain the growth of SRB for long periods without the addition of other substrates.…”

“…Although there have been many reports utilizing organic solid waste as a carbon source for SRB (Choudhary & Sheoran, 2011;Gonçalves et al, 2008;Martins et al, 2009),most of these reports were based on a batch process.There have been some successful studies performed in continuous culture for sulfide production; however, it was reported that a direct or simple carbon source such as ethanol and acetic acid was used instead of a complex organic waste (Alvarez et al, 2007;Ashe, N.L. et al, 2008).…”

Biological sulfate reduction has been slowly replacing chemical unit processes to treat acid mine drainage (AMD). Bioremediations for AMD treatment are favored due to their low capital and maintenance cost. This paper describes the available AMD treatment, current SRB commercialization such as THIOPAQ® and BioSulphide® technologies, and also the factors and limitations faced. THIOPAQ® and BioSulphide® technologies use expensive carbon sources such as hydrogen as the electron donor. This paper discusses the possibility of organic solid waste as an alternative substrate as it is cheaper and abundant. A possible AMD treatment system setup was also proposed to test the efficiency of sulfate-reducing bacteria utilizing organic solid substrate.

“…Once the pH was raised above pH 4, SRB were able to grow and provided greater than 50% sulfate removal. Goncalves et al (2008) investigated brown seaweed and sugarcane bagasse as substrates for SRB growth. Two columns were run, one inoculated with SRB and the other not.…”

A review of literature published in 2008 and early 2009 on research related to the production of acid mine drainage and/or in the dissolution of minerals as a result of mining, with special emphasis on the effects of these phenomena on the water quality in the surrounding environment, is presented. This review is divided into six sections: 1) Site Characterization and Assessment, 2) Protection, Prevention, and Restoration, 3) Toxicity Assessment, 4) Environmental Fate and Transport, 5) Biological Characterization, and 6) Treatment Technologies. Because there is much overlap in research areas associated with minerals and mine drainage, many papers presented in this review can be classified into more than one category, and the six sections should not be regarded as being mutually–exclusive, nor should they be thought of as being all–inclusive.

“…Duration of honeymoon period is strictly related to both the specific characteristics of the apparatus (column volume and type of filling), and the input variables (feed flowrate and composition). In the literature, different saturation periods were reported depending on the experimental set up: these values ranged from 20 to 50 days to 3–8 weeks .…”

A dynamic model was developed for representing the abatement of sulfates and metals in column reactors inoculated with sulfate reducing bacteria. The model framework includes both bioactive mechanisms (bioreduction of sulfates and bioprecipitation of metals) and passive abiotic mechanism (sorption onto the column filling). Sorption capacities of column filling material were determined by dedicated tests of sulfate and cadmium removal. These experimental data implemented in model framework denoted that before steady state sorption mechanism could predominate over bioactive mechanism. Sensitivity analysis confirmed that, varying sorption and bioreduction parameters in typical range of laboratory scale systems, sorption cannot be neglected before steady state. An operative equation was obtained by literature data and model simulations showing that in the majority of works reported in the literature the operational times used for column experiments are not sufficient to saturate column sorption capacity. © 2013 American Institute of Chemical Engineers Environ Prog, 33: 70–80, 2014
