A prefabricated system for the treatment and purification of town sewage or industrial waste

摘要

This sewage treatment system involves assembling prefabricated elements prepared in the factory and made as illustrated in Fig. 1. There are two mushroom-shaped cylindrical tanks, in the first of which separation of solid and floating bodies occurs together with the mixture of powders by molecular adhesion. In the second tank the following processes occur: oxygenation, settling of sludge and a series of filtration processes using materials suitable for the purpose, obtaining water to be recycled or used for agriculture.
