Design of an industrial vehicle mounted filtration system for sewer cleaning

Mackay, Roydon (2018) Design of an industrial vehicle mounted filtration system for sewer cleaning. [USQ Project]


Sewers are an essential piece of modern infrastructure, however for a variety of reasons, sewers can become blocked. When this happens a combination jetting and vacuum truck is required to unblock the sewer. It accomplished this with high pressure high flow water, and recovers the debris with vacuum. The major only disadvantage to cleaning sewers with this method is the amount of water required, and the amount of water available on board the vehicle.

To address this problem this project will design a filtration system, capable of filtering the water recovered from the sewer, and recirculating this water through the high-pressure water pump, and using the cleaned water to extend the operating time of the vehicle.

This project consists of a literature review of the available filtration methods. Design goals are set and the most appropriate filtration method is chosen to be hydrocyclones with a pre-filter and final filter. Detailed design is then undertaken on the hydrocyclones, which is then verified experimentally.

The remainder components required to make this system work were then specified and a preliminary design was completed.

The experiment provided excellent validation for empirical formula used to design the hydrocyclone with separation efficiencies over 99%, with the only minor flaw being the number of particles bypassing the hydrocyclone was too small to measure with the available equipment.

The project was successful in accomplishing its goals, however further work could be undertaken to optimise the design.
