“…Optimal performance was obtained with vertical shaft-type AnRBC, using cotton rope to form the fixed-film structure. Effects of disc rotational speed and disc submergence on the system performance of an AnRBC for treating high-strength organic wastewater were investigated to establish optimal operating conditions Yeh et al, 1997). Gas-lift reactors containing pumice particles as the carrier material were used to study the feasibility of thermophilic (55°C) sulfate and sulfite reduction, using H2 and CO2 as the energy and carbon source, respectively (van Houten et al, 1997).…”

MICROBIOLOGY Strain Isolation.A hydrogen-producing anaerobic bacterium, Clostridium butyricum strain SC-E I, was isolated from soybean meal and studied under vacuum and nonvacuum systems. The maximal hydrogen production potential by the bacteria ranged from 1.3 to 2.2 mol Hz/mol glucose, which was less than 50% of theoretical values (Kataoka et aI., 1997). The ability of a sulfate-reducing bacterium, Desulfovibrio desulfuricans, to reduce molybdenum(VI) and molybdenum(IV) in anaerobic environments was investigated (Tucker et aI., 1997). The organism was observed to be useful for removing soluble molybdenum from water. The anaerobic bacterial strain Desulfomonile tiedjei was introduced in soil slurry microcosms supplemented with acetate and formate as cosubstrates and was able to achieve dechlorination of 2.5 mM of 3-chlorobenzoate within 12 days (EI Fantroussi et aI., 1997). A DNA extraction and purification method was also presented. Godon et al. (1997) analyzed the bacterial community structure of a fluidized bed reactor fed by vinasses and established three 16S rDNA clone libraries of Bacteria, Archaea, and Procarya.The enzymes from anaerobic fungi, that is, Piromyces sp. strain E2 and Neocallimastix patricia rum strain N2, effectively converted up to 2% (w/v) microcrystalline cellulose (Avicel) to glucose and surpassed their commercial counterparts (Celluclast and Novozym) in batch degradation of 2% (w/v) Avicel (Dijkerman et aI., ]997). The anaerobic bacterium Dehalospirillum multivorans was applied to a biofilm reactor at 20°C for reduc-518 S.J.W.H.; Stams, A.

“…These works showed the importance of the hydraulic load on the performances of the reactor. An Chin Yeh et al (1997) showed that one could reach 74 to 82% of COD removal with a hydraulic retention time of 32 hours and with a volumic load between 2.4 and 9.1 g COD L 21 d 21 in mesophilic conditions. The survey of the effects concerning the rotation speed of the biodisks and the height of immersion, done by Lu et al (1997), permitted to show that the rotation speed was located around 12 rotations per minute with a total immersion of the biodisks.…”

Performances of an anaerobic rotating biological contactor (AnRBC) have been tested with winery wastewater. A 50 litres pilot has been used during a 4 month period. It was observed that the start-up took place in one month until the biofilm stabilized. Optimal performances were obtained with a COD removal close to 80%, with the following conditions: temperature of wastewater at 20 degrees C, volume load of 2 kg COD m(-3) d(-1), mass load of 0.3 kg COD kg MVS(-1) d(-1), surface load of 0.11 kg COD m(-2) d(-1). However, it is possible to enhance some experimental conditions to obtain better results, especially in increasing the total surface of the biodisk and in controlling temperature to the mesophilic optimal value (37 degrees C). In such conditions it is estimated that for 80% COD removal, volume load could approach 20 to 25 kg COD m(-3) d(-1).

“…Microscopic observations carried out in an anaerobic rotating biological contactor (AnRBC) consisted of four compartments, each one containing fifteen 12 cm diameter acrylic plastic disks, showing that the acetogenic microorganisms were predominant in the first two compartments, while the methanogenic microorganisms were predominant in the last two [27]. The volatile fatty acid profile observed in an eight chambered ABR treating complex wastewater made of cellulose and sucrose (40:60) also demonstrated that hydrolysis and acidogenesis are the main biochemical activities in the first few compartments [28].…”

This laboratory research was carried out to evaluate the performance of a multistage anaerobic biofilm reactor, with six compartments and a working volume of 70 L, for the treatment of a strong synthetic nitrogenous and high-strength wastewater at an operational temperature of 26ºC ± 0.5ºC. Initially, the performance of the reactor was studied when subjected to an increase in the hydraulic retention time (HRT) at a constant influent COD concentration of 10000 mg/L. Five different HRTs were studied: 0.25, 0.67, 1, 3 and 5 days, which were equivalent to 6, 16, 24, 72 and 120 hours, respectively . By increasing the HRTs from 6 h to 1 day, COD and BOD removal efficiencies were increased from 63% to 84% and from 66% to 87%, respectively. Moreover, at an HRT of 3 days, COD and BOD removal efficiencies were equal, reaching 93%. In the second phase of the research, the effect of adding nitrate with a concentration of 3000 mg/L at an influent organic loading rate of 10 g COD/L·day was researched on the reactor performance and the amount of biogas produced. Denitrification took place almost solely in the first three compartments of the reactor, with efficiencies of 85%, 95% and 98%, respectively. The nitrite produced was only detected in the first and second compartments at concentrations of 138 mg/L and 24 mg/L, respectively. In addition, no accumulation of nitrite was detected in the reactor. Furthermore, the denitrification caused an increase in the total volume of produced biogas from 102 L/d to 178 L/d.
