Sistemas de aproveitamento de águas pluviais em habitações unifamiliares: funcionamento hidráulico de um sistema de drenagem sifónica

Rainwater harvesting systems allow the usage of properly collected, treated and supplied rainwater for domestic use in situations without good water quality requirement. To be sustainable, a rainwater harvesting system must be truly ecological, economically viable, socially fair and culturally diverse. The key element for this system is the first-flush device, which allows the deviation of the first rains which carry a significant load of pollutants and are not suitable even for non potable use. This article develops a theoretical and experimental study on a rainwater harvesting system for use in a single family dwelling. The main goal is to describe the hydraulic operation of syphonic drainage systems by the incorporation of a first-flush device in a laboratory installed rainwater harvesting system.

The family haloplasmataceae

Haloplasmataceae is a family within the order Haloplasmatales, which currently includes one single genus and species: Haloplasma contractile. This family has unusual phenotypic features the most noticeable being a unique morphology and cellular contractility cycle and a distinct phylogenetic position between the Firmicutes and the Tenericutes (Mollicutes). Members of the Haloplasmataceae have been isolated from the upper sediments of a deep-sea anoxic brine in the Red Sea, but cultivation-independent studies have found related sequences in a wide range of biotopes including other extreme environments, contaminated soils and marine sediments, as well as intestinal samples. The isolation and description of new representatives of this family might therefore result in significant changes to the current description.

The Family Salinisphaeraceae

The family Salinisphaeraceae (Class Gammaproteobacteria, Order Salinisphaerales) comprises a single genus, Salinisphaera, and six species: S. shabanensis, S. hydrothermalis, S. dokdonensis, S. orenii, S. halophila, and S. japonica. All members of the family Salinisphaeraceae were isolated from marine/oceanic and high-salinity environments. These bacteria have coccoid or short rod morphologies and are halophilic or halotolerant. All known members of the family Salinisphaeraceae are heterotrophic, mesophilic aerobes, although S. hydrothermalis was shown to be a facultative chemolithoautotroph. Isolation and characterization of new members of the Salinisphaeraceae, as well as in-depth studies of the currently known species, will allow for a better understanding of this family.
