Technological model to collect and partially dry the active sludge from natural lakes using solar panels

Abstract

"In Natural Reservation is very important to maintain the environmental, the equilibrium for the protected species, flora, and fauna. The paper presents a technological model perfect adapted to these conditions as not disturb the local equilibrium. In the first part are mentioned the topic importance and the new problems appeared into last decades, related to the environmental problems in Natural Reservation Lake Techirghiol. This new solution placed on a mobile pontoon uses renewable resources as to collect and partially dry the collected sludge from the lake. Some experimental measurements were done in 2015, as to determine the quality of water, the main parameters, and the conditions responsible for disturbing the ecosystem. The technological model intends to solve the local problem, to collect, compact and partially dry the active sludge. The extracted sludge can be in short time integrally consumed for agricultural purpose, as ecologic and nutritive fertilizer for the adjacent area, known as the Plover, with low potential for agriculture. The sludge, well known in the past for its human therapeutic utilization, more, then one hundred ago, nowadays-due ecological and biological changes lost his efficiency. The reconstruction of the local ecologic balance and for the sludge to recover its therapeutic properties, using renewable resources, without disturbing the environment are the main objectives of this research. Some conclusions, the acknowledgements, and references are also presented."
