Obliczenia Rozprzestrzeniania Się Pyłu Drobnego W Powietrzu Atmosferycznym Z Wykorzystaniem Dyfuzyjnych Modeli Gaussa, Robert Oleniacz, Mateusz Rzeszutek Jun 2015

Obliczenia Rozprzestrzeniania Się Pyłu Drobnego W Powietrzu Atmosferycznym Z Wykorzystaniem Dyfuzyjnych Modeli Gaussa, Robert Oleniacz, Mateusz Rzeszutek

The chapter presents a comparison of results of modelling concentrations of fine dust (suspended dust PM10) in the air with the use of two diffusion models: the Gaussian plume model (used commonly in Poland), and the Gaussian puff model CALPUFF (used significantly less frequently). It indicates discrepancies in obtained results of calculations for point emitters taking into consideration three dimensional options (with the following heights: 20, 40 and 60 m and diameters of respectively: 1.0, 1.5 and 2.0 m). For particular variants, errors were visualised, resulting from use of the simple Gaussian plume model in place of the advanced CALPUFF …


Wpływ Instalacji Termicznego Przekształcania Odpadów Komunalnych Na Jakość Powietrza, Robert Oleniacz May 2015

Wpływ Instalacji Termicznego Przekształcania Odpadów Komunalnych Na Jakość Powietrza, Robert Oleniacz

At the turn of 2015/2016 it is planned to launch in Poland a few new municipal solid waste incineration plants. This type activities causes usually concerns of the local community due to their potential negative impact on air quality. Are these fears are, however, justified? The article describes allowable air emissions for new waste incinerators, the actual emissions that occur from such installations, and the current state of knowledge about their impact on air pollution.English title: The impact of installations of municipal solid waste thermal treatment on air quality.


Zastosowanie Systemu Modeli Calmet/Calpuff O Wysokiej Rozdzielczości Do Oceny Wpływu Na Jakość Powietrza Spalarni Odpadów Komunalnych W Krakowie, Mateusz Rzeszutek, Robert Oleniacz Mar 2015

Zastosowanie Systemu Modeli Calmet/Calpuff O Wysokiej Rozdzielczości Do Oceny Wpływu Na Jakość Powietrza Spalarni Odpadów Komunalnych W Krakowie, Mateusz Rzeszutek, Robert Oleniacz

In this paper there was presented a comprehensive assessment of the impact on air for the Municipal Solid Waste Incineration (MSWI) plant in Krakow with the planned start of operation by the end of 2015. Construction of the plant started in autumn 2013 in the district of Nowa Huta in Krakow. Modeling of the spread of pollutants in ambient air was conducted using an advanced multi-layer cloud CALPUFF Gaussian model, whose algorithms include, among other things, diversity of terrain. Spatial data of land area in the admitted computational domain are obtained from digital terrain model Shuttle Radar Topography Mission (SRTM3) …


Performance Evaluation Of Natural Iron-Rich Sandy Soil As A Low-Cost Adsorbent For Removal Of Lead From Water, Yee Sern Ng, Bhaskar Sen Gupta, Mohd Ali Hashim Jan 2015

Performance Evaluation Of Natural Iron-Rich Sandy Soil As A Low-Cost Adsorbent For Removal Of Lead From Water, Yee Sern Ng, Bhaskar Sen Gupta, Mohd Ali Hashim

Technical feasibility of natural iron-rich sandy soil as a low-cost adsorbent for removal of lead from water was investigated . The soil, which had an iron content of 3,719 mg/kg, was collected from Hulu Langat, Malaysia, and was used for adsorption studies without any surface modification through chemical treatment. The effects of pH, solution: soil ratio and initial lead concentration on the adsorption efficiency were studied using response surface methodology based on Box–Behnken experimental design. The results showed that pH of the solution had the highest impact on the adsorption efficiency whereby adsorption efficiency of 97% could be achieved at …


Optimization Of A Photovoltaic Pumping System In Bejaia (Algeria) Climate, Rahrah Karima Jr, Djamila Rekioua Pr Jan 2015

Optimization Of A Photovoltaic Pumping System In Bejaia (Algeria) Climate, Rahrah Karima Jr, Djamila Rekioua Pr

REKIOUA Djamila Dr

Photovoltaic energy is used in different applications and especially in water pumping and irrigation in remote areas. However, the performances of a photovoltaic pumping system can be degraded with variations of insolation and in order to maximize the efficiency of the photovoltaic energy system, it is necessary to track the maximum power point of the PV array. Many methods have been developed to determine the maximum power point (MPP). In this paper we present the results of performance optimization of a PV pumping system in Bejaia (Algeria) climate. The pumped water is desired to satisfy the domestic needs of three …
