Breakdown of air pockets in downwardly inclined sewerage pressure mains.
In the Netherlands, wastewater is collected in municipal areas and transported to centralised WWTPs by an extensive system of pressure mains. Over the last decades these pressure mains did not receive much attention in terms of monitoring of performance or maintenance. A recent inventory showed that half of the pressure mains show an increased pressure loss for no directly obvious reason. One o...
متن کاملNon-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...
متن کاملSynchronous 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....
متن کاملOn Design and Control of a Mobile Robot System for Sewerage NetworkMaintenance
The paper sketches KURT, an autonomous robot platform prototype that is able to navigate inside a network of sewage pipes. KURT is a six-wheeled device; it has modular, layered hardware and control architectures. Its sensor connguration consists mostly of stationary and one exible ultrasound sensors and of two inclinometers. In experiments run in a test sewerage system consisting of concrete pi...
متن کاملLandmark-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 ...
