Small wastewater treatment plants a solution for isolated households [articol]

Abstract

In the first part of the paper are presented the main problems specific to the rural area related to the collection, transport and treatment of waste water. If compared to those presented in [11] at the present time are made large investments for the development of sewerage systems in small localities. But there are still situations for which the small wastewater treatment plants are an efficient solution. Further are presented the main purification technologies that are suitable for small capacity installations and the requirements to which such installations must respond. Finally is presented a proposal for organizing and controlling the implementation of local wastewater treatment technologies for isolated households.
