Abstract

The object of the research is to study, invent and put into operation methods and means of treating water pumped-out above ground, so that it can be returned to the environment without damaging consequences. The treatment system finally put into use includes a pre-treatment level, consisting of three linked lagoons (ensuring an initial elimination of iron (70%), but having a slight effect (</= 30%) on manganese), followed by a filtration stage consisting of three pozzuolana filters working in parallel. Each element of the treatment system cane be isolated from the rest of the system in order to carry out maintenance on it, and the everyday upkeep of the whole requires neither chemical products, nor energy, nor any special technical knowledge.
