Sztuczne rafy jako innowacyjna biotechnologia wykorzystywana w procesie rewitalizacji środowiska morskiego

Artificial reefs as the innovative biotechnology used in revitalisation of marine environment

Ecological initiatives concerning the use of artificial surfaces placed in the littoral zone of the PomeranianBay (southern Baltic) as exemplified by construction of artificial reefs are presented. First was realized in 1990 and aimed at revitalization of the Baltic environment; the other one is in a project phase, referring chiefly to an increase of aquatic species diversity and the creation of spawning grounds for fish. In 1990 such artificial substratum showed that it is an excellent habitat for Mytilusedulis, huge concentration of fishes and its larvae were noted as well.

Problems connected with the preparation and fulfilment of required procedures, both in the preparatory phase and during realization of these types of projects, are also discussed.

Key words: artificial reef, Pomeranian Bay, succession, biocenotic factors, ecological effect

Wspomaganie koagulacji objętościowej wody z rzeki Silnica żelazianem (VI) potasu

SUPPORTING THE VOLUME COAGULATION OF SILNICA RIVER WATER BY POTASSIUM FERRATE (VI)

The paper presents results of studies on coagulation researches in the water volume of the Silnica. The study included the selection of coagulant for removing impurities from the water give it its color and turbidity and to determine its optimal dose. Optimal dose was determined for aluminum. It has been shown the superiority of a mixture of K2FeO4 and Al2(SO4)3 on alumina or ferric coagulant.

It was found that the degree of contaminant removal was determined the type and dose of coagulant. The increase of flocculant dose was shown to decrease the permanganate index of the treated water.

Key words: potassium ferrate, coagulation, flocculation, water treatment

Ocena przydatności terenów leśnych na cele energetyczne

SUITABILITY OF TIMBER USED AS ENERGY SOURCE ACQUIRED FROM WOODS AND FOREST AREAS

In the twenty–first century natural resources should be used in a sustainable manner, meeting the social needs to the extent that would not diminish the opportunities to use those resources by future generations. According to this concept, one should analyze pay special attention to the largest producer of timber material used for energy purposes, e.g. forests. In order to perform an assessment of the suitability of timber from forests and woodlands in energy production different timber resources were described, their potential was estimated and possibility of their use for energy production purposes were determined followed by a discussion of possible risks.

Key words: biomass, energetic potential, timber resources, fuel timber stream, specifications and elementary aspects of wood, conversion of timber fuel, slagging

Zastosowanie szkła wodnego w betonie z kruszywem z recyklingu i elementów żelbetowych z niego wykonanych

THE USE OF  SODIUM SILICATE IN CONCRETE WITH RECYCLED AGGREGATE AND CONCRETE ELEMENTS MADE OF IT

The article was presented to the use of sodium silicate in concrete with recycled aggregate and concrete elements made of it. The aim of this study was to design two concrete mixtures with aggregates from recycling and use them in the elements of trial. One of the mixtures was modified sodium silicate. Designed concrete results were very similar at 28 days and received the same concrete class C35/45. Sodium silicate bonding concrete accelerated rate without changing their values, a noticeable increase in higher compressive strength and tensile strength. The use of sodium silicate in concrete elements had no effect on the destructive power of the beams. The addition of sodium silicate had a positive influence on the behavior of reinforced concrete beams with 2% degree of reinforcement.

Key words: water glass,  sodium silicate, recycling, reinforced concrete structures, elements bent, concrete recycling
