Anaerobic digestion is one of the best ways to re-use animal manure and agricultural residues, through the production of combustible biogas and digestate. However, the use of antibiotics for preventing and treating animal diseases and, consequently, their residual concentrations in manure, could introduce them into anaerobic digesters. If the digestate is applied as a soil fertilizer, antibiotic residues and/or their corresponding antibiotic resistance genes (ARGs) could reach soil ecosystems. This work investigated three common soil emerging contaminants, i.e., sulfamethoxazole (SMX), ciprofloxacin (CIP), enrofloxacin (ENR), their ARGs sul1, sul2, qnrS, qepA, aac-(6′)-Ib-cr and the mobile genetic element intI1, for one year in a full scale anaerobic plant. Six samplings were performed in line with the 45-day hydraulic retention time (HRT) of the anaerobic plant, by collecting input and output samples. The overall results show both antibiotics and ARGs decreased during the anaerobic digestion process. In particular, SMX was degraded by up to 100%, ENR up to 84% and CIP up to 92%, depending on the sampling time. In a similar way, all ARGs declined significantly (up to 80%) in the digestate samples. This work shows how anaerobic digestion can be a promising practice for lowering antibiotic residues and ARGs in soil.

Land Of Israel

The second government formed by Menachem Begin, following the Likud party's narrow victory in the June, 1981, elections, represented a real change in Israeli foreign policy. Dominated by a group of hard-liners committed to the ideology of "Greater Israel" and powered by a drive for regional hegemony, this government led Israel along a nationalistic and militant course, culminating within one year in a full-scale invasion of Lebanon. The election results, which gave the Likud 48 seats in the new Knesset compared with the Labor party's 47, hardly provided an unequivocal mandate for the pursuit of Begin's far-reaching political program, a program that can be summed up in the two words Eretz Yisrael—the whole land of Israel. Nor could a coalition with the religious parties, which commanded a wafer-thin majority of 61 in the 120-member Knesset, be considered a natural vehicle for bringing about such a radical change in foreign policy.

The technology that consists of treating sewage on submerged granular filters is now far beyond the stages of research and testing on pilot units. Fifteen or so full-scale facilities are in operation in France using, as a biological treatment stage, the fixed biomass technology as realised by the Biocarbone process, particularly for the treatment of sewage from built-up areas along the seaboard. These are cases where the advantages of this technique can be put to decisive use. The Mediterranean seaboard is an ideal site for this technology. Cases in point are the waterworks of Sanary Bandol (pop.60,000) and Perpignan (pop.160,000), that have been in operation for two years and one year respectively. Waterworks in Monaco (pop.100,000) and Antibes (pop.170,000) will be commissioned in 1989 using the same technology. Results obtained during intensive controls show that the fixed biomass, designed with a suitable industrial technology, is capable of producing in routine conditions, on full industrial-scale plant, a very good quality effluent. (COD : 70 mg/l, TSS : 20 mg/l) for pollutant loads in the order of 8 kg COD/m3 day. It enables the fluctuations in the daily flow-rate and pollution load of the influent to be absorbed. The units currently being built are examples of what can be done in compact roofed facilities incorporating a fixed biomass treatment stage, with the objective of reaching a no-nuisance level.

The possibility of improving the efficiency of aerated lagoons treating pulp and paper industry effluents by introducing a support material for microbial growth was studied on a pilot plant scale. Two 20 m3 pilot plants were operated for approximately one year in parallel with full-scale aerated lagoons at two Swedish pulp and paper mills. A support material specifically developed for application in aerated lagoons was installed in the pilot plants. A considerably higher treatment efficiency was obtained in the pilot plants than in the full-scale lagoons. While 30-40% of the COD was removed in the full-scale lagoons, a COD-removal of 60-70% was achieved in the pilot plants. Phosphorus, an important discharge parameter at both mills, was removed to 60-70%, while the removal in the full scale lagoons was only 0-10%. The suspended solids in the treated effluent after clarification was around 20 mg/l.

The first full-scale phosphate removal plant is nearly one year in operation. Values of 0.5 mg/l P or less are possible. No extra surplus sludge is produced, but a relatively small amount of waterfree pellets, which can be reused in the phosphate processing industry.
