Opis:: Biofiltration is the biological degradation of gaseous pollutants and is one methods of deodorizing disruptive malodorous gases. Micro-organisms play a central role in this process. As a result of their work, non-toxic compounds are produced. Biofiltration belongs to the methods that are low to non-waste producing. This is an alternative to classical methods used so far. The research on the improvement of process parameters and increasing its efficiency is being carried out. The applied solutions referred to above still constitute unresolved problem and for this reason are seldom used. This article presents a mechanism for biofiltration of odorous gases. The article is devoted to the mechanism of malodorous gases biofiltration on the basis of a study carried out on the half-scale support.

Opis:: Secondary processing of waste from metallurgical and other industries becomes an urgent issue in the face of increasing anthropogenic pressure and a shortage of sources of materials. The paper shows the results of chemical and technological studies of processes, executing in the Cu(II) – Cu(I) – Cl^- – CO – H₂О system. The processing technology of copper-bearing intermediate products multicomponent leaching solutions, permitting high purity copper production at the least economic cost, is proposed.

Opis:: Podstawowym źródłem zaopatrzenia ludzi w wodę pitną są wodociągi. Jakość ujmowanej do wodociągu wody może ulec pogorszeniu z powodu licznych zanieczyszczeń. Woda, w tym przypadku, powinna być oczyszczana za pomocą filtrów domowych. Najskuteczniejszym urządzeniem doczyszczającym wodę ze szkodliwych związków chemicznych oraz bakterii i wirusów jest zestaw składający się z filtra mechanicznego, sorpcyjnego, odwróconej osmozy i mineralizatora.
Water supply systems are the basic source of potable water. Quality of the water entering a water supply system can be lowered by secondary pollutants. 1fthis is the case, water should be cleaned with the use of home filters. The most effective one in removing all water impurities is a system comprising a mechanical, sorptive, reverse osmosis filter.

Opis:: 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.
