Abstract
This research is part of the RO-BG Cross-Border Cooperation Program, project “CLEANDANUBE”, MIS-ETC 653, which has finalised by providing a common strategy to prevent the Danube’s pollution technological risks with oil and oil products. This paper presents a new sustainable water purification solution. A short introduction will be offered and an overview regarding the research and new methods to greening the waste is provided. The theoretical aspects of the centrifugal separation phenomenon are studied and the preliminary project bases were established. The paper conveys the possible constructive variations and the technological implications of those. Ultimately, the technical project for a new water purification solution and conclusions with critical points encountered during the designing phase are presented.
Highlights
All EU countries use a common approach for river basin management conveyed by the adoption of the EU Water Framework Directive (2000/60/EC) [1], and based on this; a Management Plan of Danube River Basin was elaborated
The new water purification solution proposes the use of the most effective and used multiphase mixtures separation method based on the difference between the different specific weights of the components
The water purification solution must meet the following conditions: to be provided with a floating system to maintain it over the level of water; to create a barrier that will not allow the crossing of polluted waters downstream; to be provided with a admission system for the polluted waters with a rough preliminary filtration of the collected products
Summary
All EU countries use a common approach for river basin management conveyed by the adoption of the EU Water Framework Directive (2000/60/EC) [1], and based on this; a Management Plan of Danube River Basin was elaborated. The presence of oil waste is a major problem in terms of environmental factors, as well as economic. These wastes are hazardous for fauna and flora and further investment development is needed to greening the affected areas. Analyzing the risk factors of shipping accidents that cause oil pollution, we can highlight the categories: Risks arising from physical and chemical properties of certain. Waste oil has a composition consisting basically of three compounds phase’s types: - The first part consists of phase oil and contains various species of heavy hydrocarbon compounds and resins or asphalt category. - The second phase consists of water in various minerals that are dissolved. The novelty of the solutions presented in this paper is an entirely different technology (centrifugation), that will complement and improve the existing ones, in order to minimize the effects of pollution, the response time and the intervention time in case of pollution, as well as to increase in the same time the capability and efficiency of the separation process for those three phases
