THE ASSESSMENT OF CHANGES FROM THE NATURAL ENVIRONMENT AND SOME POSSIBILITIES TO REESTABLISH THE ECOLOGICAL EQUILIBRIUM
APRECIEREA SCHIMBĂRILOR DIN NATURĂ ŞI A CĂILOR DE RESTABILIRE A ECHILIBRULUI ECOLOGIC

Always meditating on the eternal question, regarding the appearance and meaning of live on Earth, on the correctness and complexity of the definition of these phenomena, on the mode of perceiving the ways which life on Earth has gone during its evolution, on the principles of evaluating the character of changes in the biosphere, etc., we came to the conclusion that it would be useful to follow the logic of wise aphorism „Auf eins warum- Eins – zehn darum”to which the Germans resort in similar cases. If paraphrased, this sayving warns us that to give a comprehensive explanation to a „Why?”, you need to fiind ten answers to „Because”.
However, to facilitate and provide greater convenience to the process of identifying the causes and peculiarities of the appearance of various phenomena and changes in nature, of elucidating the principles of initiation and manifestation of any changes, we consider it would be more reasonable to divide the history of evolution in time of nature, in particular, and of the planet Earth, in general, in two periods: the first, which began in the most ancient times of the existence of the planet Earth and in which all natural processes have been conducted exclusively by the laws of the space, and the second, that followed the appearance of Homo sapiens species on Earth and in which the socio-human „laws” went into action.
Since the „moment” of appearance on planet Earth of parasitic phenomenon, a phenomenon that led to the global pathology, there were established new sets of specific regularities, through which the parasitic processes are directed in all their complexity. But we shall about these processes in a more detailed way in the following publications.

The paper present the results of a research that aimed to reveal customers’ perceptions on the relationship Water Quality – Human Health and quality of life – Environment Protection in order to find better ways to educate them towards a sustainable behavior. Thus, it was discovered which are, in customers’ opinion: the importance of having clean waters through wastewater treatment for customers’ health and quality of life, the evaluation of the effects of untreated wastewaters on customers’ health and quality of life, the relationship between these two aspects; the importance for the environment of having clean waters through wastewater treatment, the evaluation of the effects of untreated wastewaters on the environment and the relationship between these two aspects. The results show a high degree of awareness on the importance of water treatment both for human health and quality of life and for environment protection and pollution prevention and a perception of high negative effects in the case of untreated wastewaters. This is a strong premise for achieving and consolidating an environment oriented attitude of the studied population.

Geological Institute of Hungary

The geochemical exploration of the Geological Institute of Hungary made clear, that the country is geochemically not uniform, but 4 regions can be divided. Those environmental-geochemical circumstances which connected to health issues in Hungary is coming from the lack of certain elements, rather than having too much from them. From the literature that is known that the bigger part of the country is suffer from the lack of I, Se, F and Mo, and this results already some health consequences in humans, animals or plants. Other kind of geochemical anomalies occur in the eastern region which was separated because of the mining-heavy industrial contamination of the area, so there are more non-ferrous metals with concentration significantly over the contamination limit value (mainly Cd). To find out whether these heavy metals could get into the food chain or not, it will be one of our future research topics.

Transnistrian region is industrial base of Moldova, which have made most releases of harmful substances in the environment. Since the 80’s of XX century the enterprises from Tiraspol have emitted into the atmosphere over 900 000 tones of pollutants. The main enterprises with high polluting capacity are represented by the electricity industry. With the change of raw material sources and socio-political conditions, the volume of discharges dropped to 5000-10000 tones. In this paper is presented the appreciation of pollution of superficial soil layer with heavy metals and with radionuclide Cs-137 of the Tiraspol city region and the monitoring of diffusion of this radionuclide in vegetation. The Cs-137 content of 160.36 Bq/kg, found in the superior layer of soil profile collected from zone 1, is above the expected limit. Another part of the work is dedicated to health state of human population in Transnistria region, accompanied by cancer diseases, which could be provoked by soil contamination with heavy metals and radionuclides.

Wastewater treatment plants must to operate continuously, compliance with increasingly stringent regulations. Activated sludge processes control, integrated component of these plants, represents an actuality challenge. Due to the complexity of biological and biochemical phenomena, define of uniform test condition or lack of standard evaluation criteria, the assessment and comparison of control technics is difficult. The benchmark (BSM1) is a simulation environment defining a plant layout, a simulation model, influent loads, test procedures and evaluation criteria. The benchmark plant is composed of a five-compartment activated sludge reactor consisting of two anoxic tanks followed by three aerobic tanks. The plant thus combines nitrification with predenitrification in a configuration that is commonly used for achieving biological nitrogen removal in full-scale plants. The activated sludge reactor is followed by a secondary clarifier. The influent dynamics are defined by means three different weather conditions: dry weather, rain weather and storm weather. The paper describes in details this simulation platform and the way of use it in Matlab Simulation environment.

Universitatea Politehnica Bucureşti

As a result of the continued increase in energy and water consumption (due to the exponential growth of the global population), a need to reuse wastewater emerged in areas such as the industry, agriculture, sewage etc. This generated the need for new technologies or improvement of the old ones to treat wastewater to certain standards. Thus, membrane technologies were developed and are being used at an increasing scale worldwide due to their high performance. The tubular membrane technology applied to a membrane bioreactor and tertiary treatment configurations for filtration are the solution to wastewater treatment at the levels necessary for its reuse in different areas of the industry or as drinking water; it demonstrates a series of benefits in wastewater treatment for reuse in comparison to conventional treatment procedures such as sand filtering or active sludge treatment ea and the treatment plant occupies a smaller space.
