The paper presents an analysis of a chain index of water supply and wastewater infrastructure development dynamics in Poland in the years 2003-2013. The work aimed at determining the development index rate (relative growth) of water supply and sewage systems in Poland divided into 3 basic territorial units (rural, urban-rural and urban districts). Moreover, the paper describes the dynamics of changes concerning water consumption, share of population using water supplied by water supply systems, percentage of households possessing a bathroom and flush toilet and the share of population using sewage system during the analysed period. Conducted analyses used among others the chain index of dynamics to determine the rate of observed changes. The analysis revealed the greatest rate of changes for the indices characterising sewage system and the share of population using the system and wastewater treatment plants. Despite the fact that rural areas were characterized by definitely the highest values of the rate of changes and chain index of changes dynamics, the differences between rural and urban areas concerning water supply and wastewater infrastructure in Poland are still considerable.

In this paper was analyzed selected components of technical infrastructure functioning in rural areas of the Malopolska, Świętokrzyskie and Podkarpackie Voivodships. The level of equipping rural areas with specified infrastructure elements was evaluated in the form of density and availability of infrastructure components. The work has been specified the rate of change in the analyzed indicators. In each of the provinces was separated 4, homogeneous groups of municipalities due to the level of infrastructure and standard of living. The lack of consistency in the level of the dynamics of the development of infrastructure with the dynamics of the percentage of residents using the equipment was noted. A positive phenomenon is that the development of the sewage system in all three voivodships has a higher average rate than the average rate of the development of the water supply system. This is particularly important due to the significant underdevelopment of the sewage system in relation to the water supply system.

The objective of the paper was to analyse the use of the designed photobioreactor for freshwater microalgae cultivation in the controlled laboratory conditions. The work covered the design and construction of photobioreactors (PBR) and setting up comparative cultivations of freshwater microalgae chlorelli vulgaris along with determination of the biomass growth intensity for a varied amount of supplied culture medium. It was found out that the constructed PBR may be used for microalgae cultivation in the controlled conditions. The impact of the culture medium amount on the growth of chlorelli vulgaris was proved. As a result of the increase of culture medium concentration to 30.1-120.4 ml·l-1 of water, dry mass in photobioreactorsincreased respectively from 1.33 g·dm-3 to 4.68 g·dm-3.

Celem pracy była analiza możliwości wykorzystania zaprojektowanego fotobioreaktora do hodowli mikroglonów słodkowodnych w kontrolowanych warunkach laboratoryjnych. Zakres prac obejmował projekt i wykonanie fotobiorekatorów (PBR) oraz założenie hodowli porównawczych mikroglonów słodkowodnych chlorelli vulgaris wraz z określeniem intensywności przyrostu biomasy dla zmiennej ilości dostarczanej pożywki. Stwierdzono możliwość zastosowania zbudowanych PBR do hodowli mikroglonów w kontrolowanych warunkach. Wykazano wpływ ilości pożywki na rozwój chlorelli vulgaris. W rezultacie zwiększenia stężenia pożywki od 30,1-120,4 ml·l-1 wody, nastąpił w trakcie trwania doświadczenia przyrost masy suchej pozostałości w fotobioreaktorach odpowiednio od 1,33 g·dm-3 do 4,68 g·dm-3.

Eutrofizacja antropogeniczna stanowi największe zagrożenie dla wód powierzchniowych zarówno w Polsce, w Europie, jak i na całym świecie. W obliczu groźby utraty gospodarczych i biosferycznych funkcji ekosystemów wodnych podjęto działania w poszukiwaniu efektywnych rozwiązań, zmniejszających zawartość substancji biogennych w wodach powierzchniowych, w celu zahamowania procesów eutrofizacji. Świadomość ogromnej i niedocenianej roli małych cieków i małych zbiorników w obszarach wiejskich oraz ich funkcji przyrodniczej stanowiły przyczynek do podjęcia badań nad zastosowaniem układów filtracji z użyciem zeolitów naturalnych do poprawy parametrów biochemicznych tych wód. Biorąc pod uwagę rozwój technik adsorpcyjnych, prowadzone analizy skierowano na minerały porowate, do których należą zeolity naturalne. Analizy przeprowadzono w reaktorze zatopionym z utwierdzoną biomasą z zastosowaniem zeolitu naturalnego – klinoptylolitu, wykorzystując wodę modelowego zbiornika zasiedlonego. Na podstawie przeprowadzonych badań stwierdzono, że klinoptylolit można zastosować jako materiał złoża w procesie usuwania związków azotowych, w celu przywracania procesów samooczyszczania wodom powierzchniowym.

Anthropogenic eutrophication is the greatest threat to surface waters not only in Poland, but also in Europe and around the world. Facing the fact that economic and biospheric functions of aquatic eco-systems are inevitably endangered, measures have been taken to search for effective solutions of reducing the nutrients content in surface waters, which would inhibit the eutrophication processes. The awareness of the vast and underestimated role of small watercourses and reservoirs in rural areas and their natural functions, where a contribution to undertake research on the use of filtration systems using natural zeolites to improve the biochemical parameters of these waters. Taking into considera-tion the recent development of adsorption techniques the authors’ attention was directed to analyzing porous minerals including natural zeolites, such as clinoptilolite. Tests were carried out using the im-mersed reactor system with biomass immobilized on the surface of clinoptilolite – a natural zeolite. Water used for the tests came from a model, biologically active reservoir. Chemical tests using the colorimetric method, revealed the concentration of nitrogen compounds in the water, allowing the au-thors to estimate the effectiveness of nitrogen compounds extraction. Based on the conducted studies, it was found that clinoptilolite can be used as bed material in the process of removing nitrogen com-pounds, in order to restore self-purification capabilities of surface waters.

Plastics are the widely used materials and their application increases every year considerably. Therefore, appropriate waste management policy should be used in relation to the utilization or recycling of scrap plastic components. Although most of these materials refer to thermoplastics, a huge widening demand is observed in the field of thermosets. They find a wide range of applications as the dielectric or insulating materials, high-current breaker switches, sensors and other electrical and electronic devices, as well as high-resistant sleeves in mechanical devices. The substantial part of the thermohardening products is used in a car, heavy, light, chemical industry and agriculture as well. The thermohardening wastes contain a large amount of combustible fraction as thermosetting resins, and various materials as a different kind of metals group like ferromagnetic and copper. Therefore, they are potential sources of energy and secondary materials. Application of thermal methods for the utilization of these wastes in the pyrolysis process was investigated. The development of the utilization of these wastes with the possibility of gas and liquid substance recovery as a potential source of energy on a commercial scale is the main aim of this paper.
