Devastation of the environment by landslides activated by construction

Summary The landscape environment is presently formed by the system in which there are natural, as well as anthropogeneous components. There is natural direct and inverse relation between them. The possibility and method of construction of a technical work depends on specific natural conditions. Of decisive influence are mainly the rock relief, groundwater and geodynamic processes, which Matula (1976) terms the main components of the engineering geological environment. The natural conditions of the West Carpathians are suitable for the occurrence and development of slope movements. More than 3% of the total Slovakian area is covered by landslides and by other slope movements of a varied degree of activity. Based on actual examples of an incorrect procedure in erecting some of the ground, hydrotechnical and transport constructions the paper analyzes the causes of landslide reactivation and devastation of the environment. To avoid negative changes in the geological environment engineering geological documents are prepared for more important investment units, comprising predictions of changes induced by construction.

Dégradation de l'environnement par la réactivation de glissements sous l'influence de constructions

Résumé Le paysage est le résultante de composants naturels, ainsi que d'influences anthropiques. Il y a un rapport mutuel direct et inverse entre ees facteurs. La possibilité de construire un ouvrage et les méthodes employées dépendent des conditions naturelles spécifiques. Les facteurs principaux sont la morphologie du site, l'eau souterraine et les phénomènes géodynamiques, que Matula M. (1976) appelle les composants principaux de l'environnement de la géologie de l'ingénieur. Les conditions naturelles des Carpates Occidentales se prêtent à l'apparition et au développement de mouvements de versants. Plus de 3% de la superficie totale de la Slovaquie sont concernés par des glissements et autres mouvements de versants d'une intensité variable. A partir d'exemples concrets de mauvaises réalisations de travaux souterrains, de barrages et d'infrastructures de transport, l'article analyse les causes de la réactivation des glissements et de la dégradation de l'environnement. Pour éviter ces influences négatives sur l'environnement géologique, on prépare des documents géologiques et géotechniques pour des travaux plus importants et qui incluent la prévision des changements provoqués par les constructions.

Water purification of dyes by ceramic membranes modified by pyrocarbon of carbonized polyisocyanate

Pyrocarbon modification of microfiltration ceramic membrane from aluminum oxide by carbonization of polyisocyanate has been carried out. The structure of pyrocarbon was regulated by means of water, glycerin and nickel chloride. Water of purified of dyes by pressure-driven method at the pressure in the range 0.5–1.1 MPa. The retention coefficient and specific capacity of modified membranes for direct scarlet varies respectively from 84.3 to 99.99% and from 0.8 to 32.5 dm³/(m²?h) and brilliant green—from 45 to 99.99% and from 2.5 to 8.8 dm³/(m²?h) and they are determined not only by working pressure, but the structure of pyrocarbon too.     

Purification of cork processing wastewaters by ozone,by activated sludge,and by their two sequential applications

Wastewaters generated in the cork processing industry were treated in continuous reactors by means of single treatments separately-a chemical ozonation and an activated sludge system-and then by both sequential processes-ozonation followed by aerobic degradation, and aerobic degradation followed by ozonation. The removals obtained in the ozonation alone were 12-54%, 65-81%, and 55-89% for the COD, total phenolics, and absorbance at 254 nm, respectively, while the consumed ozone yield ranged from 40% to 61%, and the biodegradability (BOD(5)/COD) varied from an initial 0.60 to final values between 0.68 and 0.93. The optimum hydraulic retention time and ozone partial pressure were 3 h and 3 kPa, respectively. The stoichiometric ratio was 0.56 g of organic substrate degraded per g of ozone consumed, while the rate constants obtained for the ozone disappearance and for the organic matter degradation were 4490 L g COD(-1) h(-1) and 1970 L g O(3)(-1)h(-1) respectively. The presence of hydrogen peroxide or UV radiation in addition to ozone increased the values of organic matter removal as well as the stoichiometric ratio and the rate constants. The aerobic treatment by the activated sludge system yielded COD removals between 13% and 37% for hydraulic retention times between 24 and 96 h, and the Contois model gave values of q(max)=0.14 g COD g VSS(-1)h(-1) and K(1)=22.6 g COD g VSS(-1) for the main kinetic parameters. The sequential processes increased the substrate removal efficiencies in comparison with the individual processes. These enhancements were greater in the aerobic degradation-ozonation sequence than in the ozonation-aerobic degradation sequence.

Diagnosis of a transmission main by means of transients caused by a pump switch-off

ABSTRACT

Transient analysis is a powerful tool for the diagnosis of pressurized pipeline systems, based on the comparison of pressure signals acquired during transients with the results of analytical or numerical models. In this paper the analysis of a transient caused by a pump switch-off is used for the diagnosis of a transmission main managed by Sicilia Acque s.p.a. The measured pressure signals are compared with the results of a frequency domain based numerical model simulating the occurrence of a singularity in the system. The shown results confirm that accidental but rather common functioning conditions of pumping systems, such as pump switch on and off, can be easily and effectively used for their diagnosis.
