ECOREMEDIATION (ERM)
Ecoremediation comprises systems and processes which function in natural and artificial ecosystems; it protects and restores the environment. It is comparatively inexpensive and highly efficient in protection of water resources, streams, rivers, lakes, groundwater and the sea. The basic characteristics of ERM, which can be utilized and improved, are its high buffer and self-protective capacities, and preservation of natural habitats and biological diversity.
Ecosystems
In millions of years, the nature and ecosystems evolved exceptional defensive and self-protective capacity to safeguard themselves against sudden and powerful impacts and to remove their harmful consequences. Through its history, the nature has experienced many a catastrophe and survived them for this reason. Aquatic and waterside ecosystems and other wetlands have a high retention capacity and could prevent flooding as well as severe and specific physical, chemical and toxic pollution. These ecosystems neutralise toxins and efficiently reduce various pathogenic organisms. Moreover, they increase biodiversity and contribute to many so far unknown or hardly known processes maintaining the equilibrium on our planet.
The Main Purpose of ERM
ERM is used for multipurpose management of watercourses, lakes and wetlands, which enables integrated development of particular areas and contributes to the coexistence of man and nature. Therefore, the ERM is among the most successful and sustainable methods of environmental protection, from the economic and ecological point of view.
Possible Utilization
- remedy of long-term consequences of harmful human activities in the environment
- enhancement of disburdening and self-protective capabilities of habitats and running waters from non-point pollution sources
- remedy of seasonal pollution impacts, e.g. tourism
- tertiary or supplementary treatment of communal, stockfarming, industrial and other harmful wastewaters
- conditioning of water for various uses (watering, irrigation, drinking water, retention basins, etc.)
- protection of nature reserves
- protection of ground water, waterpoints and other sensitive areas
- protection against polluted water discharges in lakes and the sea
- sustainable maintenance of amelioration ditches
- buffer zones ("vegetation zones")
- revitalisation (biological restoration) of degraded watercourses, lakes, gravel pits, clay pits, puddles, etc.
- construction and restoration of eco-systems for rare and endangered plant and animal species.
