[The hygienic evaluation of a local unit for sewage treatment].

A complex of hygienic criteria was proposed to assess a Bioclere local unit for sewage treatment. These included: the effects of the organoleptic properties of sewage, better sanitary and chemical parameters, lower levels of inorganic and organic chemicals, surfactants, microbiological parameters, stability of treatment regimens. The Bioclere unit has some advantages over the similar ones and may be useful when an object cannot be connected to the sewage network.
