Opis:: The role of fibrous carrer in the formation of microbiocenosis, which provides purification of aquatic environments, was studied. The prospects of using the "Vija" fibrous carrer for cleaning the watercourses of mountainous areas were studied. The species composition, as well as the kinetics of periphyton formation on fibrous carrer, were established. The species composition of the microbiocenosis, which is formed on carrer in the mode of active aeration of landfill filtrates and the prospects of using the method of aerated lagoon for filtrate treatment were studied.

Opis:: The paper analyzes the advanced technologies of wastewater treatment with a high content of organic pollutants and ammonium ions. Two different bi-stage scenarios for the treatment of such effluents are proposed. The first scenario includes the pretreatment in aerated lagoons and the final stage at the wastewater treatment plants after appropriate dilution with municipal sewages. The second scenario also includes the first stage in aerated lagoons with a tertiary treatment at the plant for cyanobacteria cultivation with the use of obtained biomass for biofuels production. The effects of the aeration periodicity on the leachate treatment efficiency and also on the composition of microbiocenosis in the aerated lagoons were investigated. The leachates of the Lviv landfill of municipal solid waste (MSW) were used in experimental investigations. The Lviv landfill of MSW was used for domestic and industrial wastes deposition for almost six decades, since the 1960s. It was found that the highest effect of ammoniacal nitrogen removal was obtained in the mode of periodic aeration, with the cycle duration of two hours including the one-hour aeration. It was found that the microorganisms extracted from the leachates of the Lviv MSW landfill are prospective for the new biotechnologies of treatment of the highly concentrated wastewaters, since this microbiocenosis is resistant to the widespread pollutants, in particular to heavy metal ions.

Opis:: Removal of suspended solids and microorganisms from an aerated lagoon effluent with a horizontal roughing filter (HRF) was investigated. The aerated lagoon receives Qom municipal wastewater. The HRF was operated at three filtration rates of 0.5, 1.0 and 1.5 m3/(m2·h) during four month operation period. The measured values of turbidity, TSS, COD, pH, temperature and flow rate of HRF at the former filtration rate were 79±12 NTU, 100±11 mg/dm3, 190±12 mg/dm3, 7±0.1 °C, 17±8 °C and 0.82 dm3/min, respectively. The differences between inlet and outlet values of pH and temperature were not significant (P > 0.05). Measures turbidity, TSS and COD in HRF final effluent were 15±13.7 NTU, 37±295 mg/dm3, 64±39.7 mg/dm3, respectively, which corresponds to 81.1%, 63% and 66.3% removal efficiencies, respectively. A decrease of removal efficiency was observed upon increasing filtration rates. The Spearman correlation coefficients between the head-loss and removal efficiencies ranged from 0.578 to 0.968 pointing to a direct relationship. Results of modeling approach revealed appropriate compliance between the values of the observed and predicted TSS for higher filtration rates.
