Opis:
Performance of various materials such as activated carbons, carbon nanotubes, fullerene, and aluminosilicate for aquatic adsorption of micropollutants has been compared. Micropollutants (bisphenol A (BPA) and nonylphenol (NP)) were removed from artificial effluent which was spiked with standards of those chemicals. It was found that nonylphenol was more favorable adsorbed by all the sorbents than BPA. The higher adsorption capacities for BPA and NP showed single walled carbon nanotubes and activated carbon (AKPA). Slightly lower removal efficiencies of the studied micropollutants were observed for the multi-walled carbon nanotubes and activated carbon SX2. Taking into account the porous structure of the sorbents, it can be concluded that the materials containing mesopores had lower sorption capacities for BPA and NP than materials with microporous structure. Ad-sorption of micropollutants was much quicker for the carbon nanotubes than for the activated carbon.

Opis:
The effectiveness of co-treatment of leachates from an old site of municipal landfill with a dairy industry wastewater in a membrane bioreactor has been investigated. The subjects of the study were leachates collected at the municipal landfill in Tychy and dairy wastewaters from Dairy Plant in Bieruń. The determination of the most effective technological parameters of the process, i.e. activated sludge load and its concentration and types of COD fractions in the reactor influent was made. It was shown that the activated sludge load at the level of 0.06 g COD/(gDM·d) was the highest permissible one among all the investigated loads and the process run effectively within the whole investigated range of concentrations of activated sludge in a bioreactor. It was found that in the treated wastewater, the fraction of easily degradable organic compounds was the dominant one.

Opis:
The feasibility of effluent treatment in separate processes and in integrated systems has been compared. In the sorption process, carbon nanotubes were used in a pressure installation, enabling execution of the process of sorption with nanofiltration in a cross-flow system. Evaluation of treatment effects based on the measurement of typical pollution parameters (COD, TOC, phenolic index, forms of nitrogen and phosphorus) and concentration of bisphenol A. The results show poor feasibility of sorption as a process for advanced treatment of municipal effluent. Effluent polishing in integrated sorption-nanofiltration systems, however, guaranteed high removal rates of organic and inorganic pollutants.

Opis:
The effect of the membrane-forming polymer (PES, PAN and PVDF) on the fouling phenomenon has been investigated occurring on the surface of the ultrafiltration membranes used for the polishing of industrial wastewater pre-treated by biological methods. The activated sludge method in SBR reactor was used to treat dairy wastewater mixed with 10 vol. % of landfill leachate. The susceptibility assessment of polymeric membranes to the fouling phenomenon was carried out using the plate-and-frame membrane module SEPA CF-NP produced by GE Osmonics. The following properties of the mem-brane were determined: the dependence of the volumetric flux of the permeate on the process duration, the transport properties of deionized water, the relative permeability of the membrane for the flux of deionized water and for the wastewater flux, as well as the contact angle of the membranes. It can be concluded that the kind of membrane-forming polymer had an influence on the fouling phenomenon occurring on the ultrafiltration membranes used for the polishing of industrial wastewater treated in a SBR reactor.
