Opis:
According to Council Directive 98/83/EC on the quality of water intended for human consumption, concentration of the manganese in the drinking water should not exceed 0.05 mg/l. However, this level of manganese concentration is higher ingroundwaterof a community (Vitia town) in Kosovo. Groundwater is used for drinking supply of some villages and is only chlorified continuing to the reservoir from where is gravitationallydisseminated to the villages. The manganese level of the water is at the range 0.3 to 0.6 mg/l. Limestone has been provenby many researchers to be a very effective filter material in manganese removal for groundwater.A miniature filtration unit was modeled to investigate the removal efficiency of manganese.The unit consists of local limestone, where a single materialis folded in three layers of different grainsizes. In fact, the aim of this paper was to assess whether limestone as a single material acting as a "multi-media filter" can reduce the manganese concentration in groundwater. On the basis of the analysis of the single snapshot sample,the removal of manganese achieved more than 95% in filtered water. Particularly, this study demonstrates that filtering the water through three layers of different grain sizes of limestone ("multi-media limestone filter") can be a good alternative for manganese removal in groundwater.

Opis:
This paper describes one of the essential elements of Secure Workstation for Special Applications (SWSA) to cryptographic protection of removable storage devices with USB interface. SWSA is a system designed to process data classified to different security domains in which the multilevel security is used. The described method for protecting data on removable Flash RAM protects data against unauthorized access in systems processing the data, belonging to different security domains (with different classification levels) in which channel the flow of data must be strictly controlled. Only user authenticated by the SWSA can use the removable medium in the system, and the data stored on such media can be read only by an authorized user by the SWSA. This solution uses both symmetric and asymmetric encryption algorithms. The following procedures are presented: creating protected a file (encryption), generating signatures for the file and reading (decryption) the file. Selected elements of the protection systems implementation of removable Flash RAM and the mechanisms used in implementation the Windows have been described.

Nanofiber properties and the possibilities of their application in industry, including car air intake filtration materials production for vehicle engines are discussed. The attention is paid to the standard filtration materials low efficiency in the range of dust grains below 5 μm. Filtration materials properties with nanofibers addition are presented. Filter paper test conditions and methodology at the station with particle counter were developed. Filtration efficiency characteristics, and accuracy studies as well as filtration materials pressure drop differing in structure were made: standard paper, and materials with nanofibers addition. These are commonly used filter materials for car air intake systems production. Filtration materials with nanofibers addition test results show significantly higher efficiency values, and efficiency for dust grains below 5 μm in comparison with standard filter paper. It was found that there are 16 μm dust grains in the airflow behind the cellulose insert, which may be the reason for the accelerated wear of the engine’s “piston-cylinder” association. Lower dust mass loading km values of filtration materials with nanofibers addition in relation to standard filter papers were observed.

In this paper, the properties of filtering media used as porous membranes in air cleaners of modern motor vehicles have been analysed. A relation that defines the air filter life has been presented and a dust absorption coefficient km of a filtering medium has been defined. Methods of testing filter elements made of nonwoven filter fabrics and working in conditions corresponding to the primary and secondary air filtration stage have been discussed. Results of examining the filtration efficiency, threshold, and restriction characteristics of the filtering media under consideration have been analysed. The dust absorption coefficient km of a nonwoven filter fabric has been determined for the fabric working at different air velocities during the filtration. The impact of the particle size distribution of dust, changed by the intake air pre-treatment in a uniflow cyclone, on the characteristics of the nonwoven fabric under test and on the value of its km coefficient has been examined. The benefits gained from two-stage air filtration have been indicated.

Opis:
Artykuł podejmuje problem politycznych, strukturalnych i ekonomicznych uwarunkowań polskiej debaty publicznej, sprawiających, że jest w niej – zdaniem autora – coraz mniej konstruktywnego dialogu, a coraz więcej monologów udających rozmowę. Autor stawia tezę, że zjawisko to wynika zarówno z koniunkturalnych zachowań partii politycznych, jak i specyfiki funkcjonowania mediów (internetowych i tradycyjnych) poddanych regułom tzw. turbokapitalizmu. Tekst próbuje pokazać, że zamknięci w bańkach informacyjnych odbiorcy mediów przesiąkają tym sposobem „plemiennego” funkcjonowania i również coraz rzadziej potrafią ze sobą konstruktywnie rozmawiać.
The article deals with the problem of political, structural and economic determinants of Polish public debate, which, in the author’s opinion, make it less constructively dialogical and more monological, only pretending to be fully conversative. The author claims that this phenomenon results both from the cynical behavior of political parties and the specificity of nowadays media (online and traditional) obeying the rules of so-called turbocapitalism. The text tries to show that media recipients locked in filter bubbles are permeated with this style of „tribal” functioning and are also less and less able to talk constructively to each other.

Nowa norma międzynarodowa ISO 21083 definiuje metodę badania materiałów filtracyjnych podczas filtracji nanocząstek o kształcie zbliżonym do kulistego. Opisana procedura może być stosowana do wyznaczania parametrów operacyjnych materiałów filtracyjnych dowolnych klas. Skuteczność filtracji jest wyznaczana na podstawie uśrednionych wyników uzyskanych dla próbek badanego materiału w stanie wyjściowym oraz po neutralizacji ładunku w oparach 2-propanolu. Norma nie wprowadza podziału na klasy filtrów, a w raporcie końcowym z badań są podawane frakcyjne skuteczności zatrzymywania cząstek. Zakres tematyczny artykułu obejmuje zagadnienia zdrowia oraz bezpieczeństwa i higieny środowiska pracy będące przedmiotem badań z zakresu nauk o zdrowiu oraz inżynierii środowiska.
The new international standard ISO 21083 provides a method of testing filter media during the filtration of spherical shaped nanoparticles. The described procedure can be used to determine operating parameters of filtration materials of any classes. The filtration efficiency is determined on the basis of averaged results obtained for samples of the tested material in the initial state and after neutralization of the charge in the 2-propanol vapour. The standard does not introduce a division into filter classes, and in the final report of the tests, fractional particle retention efficiencies are given. This article discusses the problems of occupational safety and health, which are covered by health sciences and environmental engineering.

Opis:
Although dust-holding capacity is the primary feature of engine air filters operating in dusty environments, efficiency becomes a major factor when selecting an engine air filter. Inertial separators and high porosity or fibrous prefilters are commonly used to decrease the dust load to the main filter while high efficiency is achieved by utilizing submicron or nanofiber fibers in the main filter. The patented multi-stage filter was designed to achieve ultra-high particle removal efficiency and dust holding capacity, and long life in dusty and on highway environments. The main (final) filter is located downstream of the prefilter. The main filter is made ofpleatedfilter media containing nanofibers with a diameter in the range of40 - 800 nanometers. The upstream in-line precleaner utilizing flow-through mini cyclones has separation efficiency of 95%. A high dust capacity, high efficiency prefilter can be used instead of the precleaner. The prefilter is made of vertically lapped nonwoven filter media made from synthetic fibers of different materials to fully utilize the tribological effect. The volume of the prefilter is determined by the performance required and space allotted. This paper discusses the filter performance of high dust holding capacity engine air filters. Filter specifications, design and performance are discussed in detail. Performance characteristics of the media and full size filters were determined using on-line particle counters and the gravimetric test method. Initial and final efficiency, and dust loading performance characteristics, are provided.

Opis:
The development of an engine air filter is based on filter performance requirements, vehicle 's operational environment, available space, filter media properties, and production technology. The design process includes analyses of theoretical and empirical models describing filter media performance and aerosol flow in filter housings and through filter elements. Filter media are carefully selected based upon these models and simplified laboratory tests. The filter element design is evaluated in great detail through a series of laboratory and field experiments. The role of the engine air induction system has increased because of recent engine exhaust particulate and evaporative emission regulations. Engine lifetime, engine emission and fuel consumption depend on the air induction system design and its performance. Providing optimized solutions for these requirements dictates filter development trends. This drives the need for smaller, more compact filters and more efficient filter media with higher permeability. The efficiency can be drastically improved by applying a layer of nanofibers to a cellulose or synthetic substrate. The ISO fractional efficiency test method, that in its final stage of development, can clearly show the advantage of nanofiber filter media. This paper discusses air cleaner design including the newest in-line reduced volume air cleaners and the role of nanofiber filter media in engine air filtration.

W większości wysokoefektywnych systemów uzdatniania wody powierzchniowej filtracja pospieszna występuje po procesie koagulacji i sedymentacji oraz przed chemicznym utlenianiem i adsorpcją. W systemach uzdatniania wody podziemnej proces filtracji pospiesznej występuje najczęściej po napowietrzeniu wody, a podstawowym celem filtracji jest wówczas odżelazianie i odmanganianie we właściwie dobranych złożach filtracyjnych, w których zachodzą procesy katalitycznego heterogenicznego utleniania tych domieszek.

Opis:
The performance of a particle filter is primarily determined by its media. Today's filter media is a composition of different layers known as MULTIGRADE or MICROGRADE media. Selecting the right combination of layers requires a lot of experience. Recent progress now enables the simulation of complex structures to support the development by adding information about the media utilization. However, published results point out that the local inhomogeneity of the fiber structure plays an important role. Thus computer models have been developed to reproduce 3D fiber structures. However, these 3D fiber structures are still simplified models, as they have just a few input parameters and do not account for the production process. But state-of-the-art simulation software, such as GeoDict, provides the opportunity to import 3D images of real fiber structures as initial geometry. Micro-tomography now promises to deliver this quantitative data about the real 3D fibrous structure. In this paper first results are presented, indicating that we extracted the true fibrous structure of a synthetic media by segmentation of the raw XCT data with the software MAVI. In contrast to other publications, the packing density of the media was not used as fitting factor, but obtained without a priori knowledge. The results discussed show a reasonably good agreement with measured data for packing density, fiber diameter distribution, initial pressure drop and initial efficiency. However, it is crucial to select a region of interest large enough to be representative.

Opis:
Acid-washed asbestos, carbon fibre, and MgO with carbon fibre were used as the filter media in order to compare their filtering qualities in the estimation of the percentage of gaseous products (PGP) arising from the combustion of singlebase propellants, double-base propellants, and boron-based fuel-rich propellants. The comparison was based on an analysis of the experimentally registered influence of the propellant formulation, the propellant load, the maximum chamber pressure and the thickness of the MgO filter layer on the PGP from the fuel-rich propellant, and in particular on the PGP produced by combustion of boron-based fuel-rich propellant. The results showed that the experimental values of the PGP were closer to the theoretically predicted values when carbon fibre mixed with MgO powder was used as the filter medium. The PGP of boron-based fuel-rich propellant increased when the AP was in part replaced by HMX, when the AP content was increased and when boron was in part replaced by magnesium-aluminum alloy. In terms of the apparatus used in these experiments, the propellant loading density was found to have little correspondence with the PGP for boron-based fuel-rich propellant. The optimal propellant loading density for the chamber volume of 85 cm3 was found to be 2-2.5 g, in view of the reliability and safety of the experiment. It is emphasised that the thickness of the MgO filter layer is very important for the accuracy and reliability of the experiment, and that the optimum should be determined by experiment.
