| Abstract | |
This work evaluates the efficiency of two sequence systems of treatment of sewage involving anaerobic biologycal and physical-chemical processes. Five sets of experiments were done in the first stage of the study, using a sequence system formed with: anaerobic biologycal reactor, dissolved - air flotation, sand filtration, cartridge filtration (5 μm), filter paper filtration (1,2 μm)/ceramic filtration and nanofiltration. Another set of experiments was carried out using a different sequence system formed with: anaerobic biologycal reactor, dissolvid-air flotation, crossflow microfiltration and reverse osmosis. Every effluent resulted from the two treatment systems was evaluated and the reuse possibility (agricultural and industrial) was invetigated. The sand filtration, cartridge filtration, filter paper filtration/ceramic filtration and nanofiltration effluents (of the first step of studies) showed compatible characteristics with irrigation water but they were not compatible with water used in the majority industrial processes. On the other hand the crossflow microfiltration and reverse osmosis effluents (of the second step of studies) can be said as a good alternative to agricultural reuse and industrial reuse as well (mainly the reverse osmosis effluent).
