PROCESS AND EQUIPMENT FOR DRAGGING AND AERATING LACUSTRIAN FORMATIONS, POPULATED WITH NYMPHAEA LOTUS VAR. TERMALIS

摘要

The invention relates to a process and equipments for dragging and aerating lacustrian formations, populated with Nymphaea var. termalis. According to the invention, the process consists in evacuating, non-distructively for the biological populations, the excedentary mud deposit, settled on the bottom of the lake, up to a depth of 5 cm above the Nymphaea Lotus var. termalis rhizomes, by preparing a water/mud mixture which, from the bottom of the lake, is overflown over a Coanda sieve, into a floating settler wherefrom the separated hydrobionts, together with the cleared water, come back into the lake, while the settled mud is removed, and simultaneously or separately with the dragging operation, there is performed the water oxygenation at the saturation values, on a depth of 0.5...1.0 m, by superficial differential currents.
