Content available remote 100 lat czasopisma „Gaz, Woda i Technika Sanitarna" - historia w skrócie
PL
Rozwijający się ruch polskich stowarzyszeń technicznych i naukowo-technicznych w ostatnich latach XIX wieku i pierwszych dekadach XX wieku był wykładnikiem procesów historycznych, toczących się wówczas na ziemiach polskich. Ówczesne elity społeczeństwa polskiego dążyły do rozwoju nauki i przemysłu. Łączyło się to z dążeniami niepodległościowymi oraz wysiłkami „których celem była integracja organizacji działających w różnych zaborach. Środowiska techniczne, działające w różnych rejonach ziem polskich, starały się nawiązywać kontakty i organizować współpracę. Rezultatem było organizowanie na wzór państw zachodnich zjazdów techników polskich.

The Poznań and Lwów gasworks were established in the 1850s; the former being an urban enterprise, the latter a private company. At the beginning of the 20th century, the gasworks and the entire gas infrastructure in Lwów were seriously outdated as compared to Poznań in terms of the volume of production and technology. After the municipalization of the plant in 1898, Galicia’s capital quickly began to reduce a backlog using the effects of technical progress in Europe. As part of the modernization and expansion of both gasworks in the fi rst decade of the 20th century, modern water-gas plants with Humphreys & Glasgow systems were commissioned in Poznań (1900) and Lwów (1906). Moreover, the gas network and public lighting system were intensively developed in both cities. In 1910, 11.3 million cubic meters of gas fl owed into the municipal network in Poznań, whereas 6.1 million cubic meters did so in Lwów. The number of gas street lights amounted to 3456 and 3541, respectively. In both cities, major extensions of their gasworks were planned in the very years preceding the outbreak of World War I. In Poznań, the investment was implemented to a large extent during World War I, when a unique and innovative Koppers retort house and a dry-seal gas holder with a capacity of 50 thousand cubic meters were built. In Lwów, due to the Russian occupation of the city between 1914 and 1915, ultimately the works had to be stopped. Due to wartime hardships, the planned Glover-West vertical retort house was eventually replaced by the Dessau vertical retort furnace. The retort house was completed in 1917, but the rest of the investment was fi nalized in the fi rst years of the Second Polish Republic. Nevertheless, when the Partitions of Poland ended, both gas plants were among the largest and most modern in terms of technology in the country, in which their directors at the time, Hans Mertens in Poznań and Adam Teodorowicz in Lwów, had considerable merit.

Content available remote Statistical approach to assessing groundwater pollution from gasworks
EN
The primary objective of this work was to ascertain the effectiveness of the Microtox system in assessing the quality of groundwater polluted with by-products of coal pyrolysis. Another major objective was to investigate how biological treatment contributes to the change in water toxicity. Making use of the results of toxicological instrumental analyses, as well as of statistical methods, attempts were also made to specify which particular compound is the main contributing factor in the toxicity of water. When used for assessing the progress of the treatment process, the Microtox test proved very useful for application in the treatment of groundwater polluted by gasworks. The results obtained with this test have provided a reliable description of the course of the technological process, which can be efficiently corrected owing to a quick availability of the results of toxicological analysis. Another benefit offered by the Microtox test is that the use of statistical methods makes it possible to decide which of the compounds being components of the mixture is responsible for the toxicity of an environmental sample.

Content available remote Metody rekultywacji terenów wyłączonych z eksploatacji gazowni klasycznych
EN
Defining acceptable pollution level characteristic for traditional gas-works activity in the ground and underground waters. Methods of re-cultivation of areas contaminated by traditional gas-works. Analysis of effectiveness based on up-to-date experiences in Western European countries.
PL
Stara technologia uzyskiwania gazu z węgla w procesie suchej destylacji stosowana w gazowniach na obecnych terenach Polski od półtora wieku powodowała powstawanie kłopotliwych odpadów. Są to silnie skoncentrowane i bardzo szkodliwe dla środowiska związki organiczne, wśród nich wielopierścieniowe węglowodory aromatyczne, fenole oraz związki lotne z grupy BTEX. Likwidacja tej technologii związana z przejściem na zasilanie odbiorców naturalnym gazem ziemnym oraz likwidacja wielu zbędnych budynków i instalacji nie wiązała się z zasadniczą sanacją zanieczyszczonych przez dziesięciolecia terenów.Dzięki współpracy z Gazownią Bydgoską oraz w ramach międzynarodowego projektu INCORE (Integrated Concept for Groundwater Remediation) finansowanego ze środków 5 Programu Ramowego UE rozpoznano na terenie starej gazowni w Bydgoszczy ogniska zanieczyszczeń gruntu i wód podziemnych, drogi migracji skażeń oraz oceniono stopień ryzyka środowiskowego. Zaproponowano też naukowo i ekonomicznie uzasadnione metody sanacji wykrytych zanieczyszczeń.

The old gas production technology - dry coal distillation - caused uprising of specific waste. These are concentrated, mainly organic chemicals such as PAH, phenols and BTEX, hazardous to the environment, especially soil, groundwater and some cases (like in Bydgoszcz) also surface water bodies. Closure down of the old gas-works due to the new natural gas utilization technology did not come along with cleaning up the areas effected by the old technology..In cooperation with the Gazownia Bydgoska Enterprise and in the frame of international INCORE project (Integrated Concept for groundwater Remediation) financed by the European Union 5* Framework Programme the old gas-work area in Bydgoszcz was investigated - pollution sources of soil and groundwater were identified, pollution migration paths were detected and the human health risk assessment were conducted. Also the remediation method was proposed - the best from both scientific and economical point of view.

Analysis of the range of pollution problem for areas excluded from traditional gas stations exploitation in Poland. Defining products' sort and their marking methodics for those remaining after coal degassing that influence the degree of ground and water pollution in areas of disconnected traditional gas stations. Marking of substances specific for gas industry in water, ground and soil air.
