“…Including the prefi ltration the overall level of PAHs removal reached 85%. The effi ciency in removal of PAHs from water reached 80% and 90%, respectively [2,8]. In UF the relatively high degree in removal of PAHs from the wastewater was observed, despite the fact that the molar mass PAHs are much lower than the "cut-off" (70 kDa) and the pore radius of applied membrane.…”

“…Pre-treatment should be applied in order to protect the membrane. This process allows for removal of suspended solids, colloids and a variety of dissolved compounds, which during the adsorption on the surface of the membrane may contribute to reducing the hydraulic effi ciency [2,4,12,19]. The most common applications of ultrafi ltration are: treatment of natural water, brackish water pre-treatment before desalination by reverse osmosis, purifi cation of macromolecular solutions and industrial wastewater also contaminated with oil derivatives [6,7].…”

Abstract:The paper presents the results of studies on the changes in the PAHs concentration during pre-fi ltration and ultrafi ltration (UF) processes. In the study, biologically treated wastewater (after denitrifi cation and nitrifi cation processes), discharged from the biological treatment plant and used in coke plant, was used. A gas chromatography-mass spectrometry (GC-MS) was used in order to qualify and quantify the PAHs. Sixteen PAHs listed by EPA were determined. The wastewater samples were collected three fold and initially characterized for the concentration of nitrate nitrogen, ammonium nitrogen, COD, TOC and pH. In the fi rst step, wastewater was fi ltrated on the sand bed. Total concentration of 16 PAHs in the treated wastewater before initial fi ltration was in the range of 44.8-53.5 mg/L. During the process the decrease in the concentration of the most studied hydrocarbons was observed. Concentration of PAHs after initial fi ltration ranged from 21.9 to 38.3 μg/L. After the initial fi ltration process the wastewater fl ew to the ultrafi ltration module and then was separated on the membrane (type ZW-10). The total concentration of 16 PAHs in the process of ultrafi ltration was in the range of 8.9-19.3 mg/L. The effi ciency of removal of PAHs from coke wastewater in the process of ultrafi ltration equaled 66.6%. Taking into account the initial fi ltration, the total degree of removal of PAHs reached 85%. The obtained results indicate the possibility of using the ultrafi ltration process with the initial fi ltration as additional process in the coke wastewater treatment.

“…The dissociated form of the contaminant is totally hydrated and is characterized by a greater diameter and negative ion charge, resulting in higher retention (Bick & Oron, 2005). Boron is removed from the environment mainly by means of coagulation and electrocoagulation, adsorption, and ion exchange, as well as membrane processes, i.e., RO, NF, ED, and polymer-enhanced UF (PEUF) (Bick & Oron, 2005;Bodzek & Konieczny, 2011a, 2011bBodzek et al, 2011).

In times of global crisis, there is a dynamic change in the European gas market. This leads to: - decline or stagnation in demand for gas in the industrial sector; - growing importance of unconventional natural gas; - LNGmarket development especially in terminal condensing due to the availability of rawmaterials derived from unconventional gas deposits (USA, Canada); - development of regasification terminals in Europe due to the possibility of receiving additionalmaterial; - development of gas exchanges; - development of cross-border gas pipeline connections leading to a progressive increase in the integration and linkages between markets; - emergence of unconventional gas in particular shale gas and coal bed methane; in Poland the potential benefits from shale gas exploitation offering opportunities for its wider use in the energy sector; - attention drawn to the role of unconventional gas, particularly shale gas; - periodic surplus raw materials for the European market; - renegotiation of long-term contracts for European customers; - changes in contracts, which include the introduction of partial indexation to the exchange of gas markets, modification of TorP clauses, contract volume shift to later years; - stronger bargaining position for the buyer of raw materials; - possible long-term changes in the valuation of raw material in Europe; - growing importance of short and medium-term contracts; - changes in distributor relations - [client on national markets (meaning unclear)]; - activity of new entrants to the gas markets. This paper presents the existing situation in the energy market in Poland in terms of the types of fuels used especially natural gas in the generation of electricity. It references Poland’s current energy relations with European countries, particularly with respect to the European Union. The analysis includes the size of unit energy consumption in selected EU countries. In addition, it reviews plans to build a major gas plant in Poland.
