Szerves és szervetlen anyagok sok évtizede kerülnek a környezetbe; sorsuk és viselkedésük iránt azonban főleg az utóbbi években nőtt meg az érdeklődés, miután fény derült rá, hogy-a környezetbe kikerülve sokuk perzisztens, bioakkumulációra hajlamos és már egész kis koncentrációban is toxikus. Környezeti mintákból való kimutatásuk-részben az alacson...

Implementation of an extensive urban runoff monitoring program, targeting the quantification of heavy metal and organic micropollutant loads, necessitated the development of an autonomous water sampler. The design requirements for the device were to fulfill flow-proportional continuous composite sampling of urban runoff events in a widely customiza...

Sediment Transport Model For Storm Sewer Networks Towards the Operational Risks. Sediment transport in sewer networks can be critical in economical and safety point of view. To improve the operation of the sewer networks we are presenting a model, which is capable of numerical simulations of the sediment transport in storm water network. The develo...

Sediment transport in sewers

Sewer and storm water systems in cities worldwide suffer from ageing and inappropriate wastewater networks. This challenge has to be met by systematic upgrading and preventive maintenance. It is necessary to analyse the current performance of the wastewater networks, to determine the system bottlenecks that cause system vulnerability on floods in c...

The National Water Authority (OVF) operates the national database of water supply and wastewater management. The database includes all the data produced by a man-made water cycle — beginning with the acquisition of water, continuing with its purification, delivery, distribution, canalization, its use for sewage collection, and ending with the deliv...

In the past decade, the development of chemical technologies has opened the way to use low doses of metal salts (with or without polymers), in wastewater treatment. Then this led to a combination of chemical and biological processes driven by different goals. Available experiences suggest that chemical upgrading is an efficient method to increase t...
