RIVERS AND CANALS
Biological technology can also be used in watercourses with high flow rates, using special techniques for the distribution of bioenhancers.
The ecosystem will see appreciable improvements even in a short time, especially in periods of low water flow, where water stagnation and the formation of bad odours are common. The results are particularly visible in canals with discontinuous flows, in urban environments and in tourist areas.
NATURAL AND ARTIFICIAL LAKES
All water basins, large or small, artificial or natural, deep or shallow, fed or stagnant, suffer from eutrophication and sediment degeneration; chronic, acute, generalised or in limited areas.
The only technology that can be applied is biological, because it does not require impacting structures and is economically competitive with any other technology (chemical, sediment removal, forced oxygenation, etc.). Bioenhancers can be applied, always with high efficiency, even in small, undefined areas of a large basin or for reduced periods (for the duration of acute pollution phenomena).
In ports, large quantities of polluted sediment accumulate which, if it does not have to be removed for navigation reasons, can be treated in situ with biological technology in order to stabilise the organic substance and decompose the biodegradable elements.
In port areas we also find polluted water from improperly purified civil discharges, small quantities of hydrocarbons from boats or petrol stations, dead algae accumulating in corners or rising to the surface, all of which are compatible with the use of biological technology.
The environmental impact of dredging operations can also be mitigated by using Eurovix bioenhancers applied during the work. In fact, the use of bioenhancers in ports does not interfere with the normal activities that take place there.
Over five thousand km of Italy’s coastline are subject to bathing controls: of these, over two hundred km are not suitable for bathing.
The causes that compromise bathing parameters are mainly due to the discharge of untreated or imperfectly purified civil waste into the sea through canals and rivers.
The application of Eurovix bioenhancers, immediately downstream of the source of pollution (inefficient purifiers, by-passes, illegal discharges), restores the microbiological parameters to the values required for the authorisation of bathing without creating environmental problems for the ecosystem and the fauna in the area, or health problems for the population.
There are basically two problems related to the management of water intended for irrigation: the chemical and microbiological characteristics, which are fundamental for the use in edible crops; the eutrophication phenomena which reduce the efficiency of the irrigation circuits starting from the canals, passing through the filters (when they are used) to the sprinklers.
The more extensive the irrigation network (Land Reclamation Consortia) or the more technological (fertigation, drip irrigation, precision irrigation, etc.), the more eutrophication phenomena (growth of algae and macrophytes) compromise the efficiency of the systems, increase management costs and reduce nominal water flows.
The use of chemicals is very often not compatible with irrigated crops. High filtration technologies are expensive and difficult to manage, while biological technology is the simplest, least invasive and cheapest solution to apply.
DRAINAGE AND OVERFLOW CANALS
Drainage spillways and overflows are structures that save sewage treatment plants and sewerage systems from overflows during periods of heavy rainfall, releasing raw sewage directly into the receiving water body.
Very often, if hydrodynamic conditions do not favour dilution and dispersion, the effluent remains in the immission area, compromising water quality (e.g. bathing parameters).
With appropriate technologies based on bioenhancers the drained effluent can be treated to reduce the environmental impact it has on the downstream ecosystem.
