<p>The present invention refers to a waste water treatment by an anaerobic process, which uses five main elements for obtaining an efficiency of from about 90% in DBO and SST in the treatment of water. The purpose of the invention is to provide the treatment of municipal and household waste waters with an alternative process by means of using the following elements: a pre-treatment, an anaerobic biodigester, an anaerobic filter of upward flow, wetlands (underground flow artificial swamps) and drying beds, thereby reducing operation and maintenance costs. The invention further comprises the possibility of being manufactured in stages or modules for future applications.</p> |
