Abstract

A soil-based disposal trench that has failed from a biomat slime is recovered by adding a facultative anaerobic bacteria to an effluent that flows into the disposal trench. The facultative anaerobic bacteria consumes the biomat slime and, in one embodiment, supplants a strictly aerobic bacteria in the soil that converts nitrites to nitrates. As a result, the facultative anaerobic bacteria interrupt the conventional process of nitrification, changing the nitrites to nitrogen gas.

RELATED APPLICATIONS

[0001] This application is a continuation of U.S. patent application Ser. No. 10 / 799,926 filed Mar. 11, 2004 which is a divisional of U.S. patent application Ser. No. 10 / 000,764 filed Oct. 24, 2001 which claims benefit of U.S. Provisional Patent Application Ser. No. 60 / 309,946 filed Aug. 6, 2001 and U.S. Provisional Patent Application Ser. No. 60 / 243,852 filed Oct. 30, 2000.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to waste treatment devices and, in particular, to a method of recovering a disposal trench with a biomat slime, and a method of operating a waste treatment vessel.

[0004] 2. Description of the Related Art

[0005] In a conventional non-municipal waste system, waste material flows into a septic tank. The septic tank is a separator that separates the waste material into three distinct regions. The regions include a lower layer that is formed from solids settling out of the waste material, and an uppe...
