Non-conventional Sewerage

Conventional wastewater collection systems are installed to remove human wastes from households in cities and urban areas. This system demands high water supply rates as the wastes are flushed through pipes using water that flows under gravity. This system is capital extensive, and has been found to be not suitable in urban areas with smaller population sizes. Also, for the same reason, not sui...

Synchronous municipal sewerage-sludge stabilization.

A study on a pilot plant accomplishing synchronous municipal sewerage-sludge stabilization was conducted at a municipal sewerage treatment plant. Stabilization of sewerage and sludge is achieved in three-step process: anaerobic reactor, roughing filter and a microbial-earthworm-ecofilter. The integrated ecofilter utilizes an artificial ecosystem to degrade and stabilize the sewerage and sludge....

Landmark-Based Autonomous Navigation in Sewerage Pipes

We describe a method for an autonomous mobile robot to navigate through a system of sewerage pipes. Landmarks signalling positions in the pipe system have to be detected and classi ed, where classi cation is allowed to be unreliable. Self localization is interpreted as a partially observable Markov decision problem and solved accordingly. The method is implemented and used on a prototype robot ...
