Water is one of the humans’ basic needs that are essential in daily lives. The water use related to the production of the food processing industry must at least meet the quality standards required for drinking water. The Production process water is obtained from the artesian well that has been treated with a physical treatment process. The microbiological examination result of total Coliform is 8.6 MPN/100 ml meaning that it does not meet the quality standard requirements, which is 0 MPN/100 ml (The Minister of Health Regulation Number 492 of 2010, concerning Drinking Water Quality Requirements), it is necessary to treat the production process water using a Melt Blown Filter (MBF) and UV-C rays. The purpose of this study was to determine the differences in the variation of the 1, 3, and 5-micron of Melt Blown Filter cartridge 10” in reducing the amount of total Coliform, as well as the water hardness and their effect on disinfection using UV-C rays. The type of research used is experimental research with a pretest-posttest without control research design. There is a reduction in the average total Coliform after the treatment using a Melt Blown Filter, with a result of 1, 3, and 5-micron as 2.95 MPN /100ml, 3.61 MPB/100 ml, and 7.31 MPN/100 ml with a percentage reduction of 100%, 94.5%, and 82.4%, respectively. The average total Coliform using the Melt Blown Filter equipped with the UV-C rays treatment resulted in a reduction of 1, 3, and 5-micron as 2.95 MPN/100 ml, 3.95 MPN/100 ml, 8.88 MPN/100 ml respectively, with a reduction percentage of 100%, for each treatment. The data analysis for total coliform using the One-Way ANOVA test resulted in a pvalue of 0.001, the effective variation obtained is 1-micron MBF equipped with UV-C rays. The analysis of results pertaining to the water hardness data showed that the use of Melt Blown Filter could not reduce water hardness, but the UV-C rays could still be used accordingly. The data analysis for water hardness was performed using KruskalWallis with a p-value of 0.820, meaning that there are no differences in Melt Blown Filter variation on the results of total water hardness value.

W artykule przeanalizowano zalecenia dotyczące kryteriów oceny ryzyka dla prac w przemyśle off-shore wprowadzonych przez administracje państw mających największy udział w badaniach i wydobyciu morskich złóż naturalnych. Podano główne czynniki ryzyka dla obiektów prowadzących prace wydobywcze w warunkach morskich oraz metody jego określenia i przyjęte granice akceptacji. Wsparto się danymi statystycznymi zebranymi w ogólnoświatowej bazie danych sporządzonej przez Norweskie Towarzystwo Klasyfikacyjne DNV - Worldwide Offshore Accident Databank - WOAD obejmującej wypadki w sektorze off-shore od roku 1970 do 2014. W szczególności analizie poddane zostało ryzyko występujące na obszarach polskiej strefy ekonomicznej w związku z intensywnym rozwojem polskiego przemysłu badawczo wydobywczego.

The basic rules shaping of filtration paper, and rules of selecting main dimensions of the cylindrical and panel filter cartridge are shown. Types of paper filters cartridge to the engine intake air filters of cars and trucks are presented. Shaping of traditional filters cartridges and modern design of filters, which is characteristic of the axial flow of air and low flow resistance are shown. Ways to prevent contact between the pleats of filter cartridge are presented. The criteria of selection of filtration papers to filter cartridges of intake air filters of engine are discusses. It has been shown that the selection of the active surface of paper according to maximum filtration velocity criterion is necessary, but not sufficient. It has been shown the need to have of many experimental data, which are characterized by a concrete type of paper, and the dust absorption coefficient.
