PhD Studentship: Intelligent Sensor Fusion for Sustainable Cleaning in the Food Industry

We are seeking a highly motivated PhD researcher to develop innovative technologies that improve sustainability in the food industry. The UK food and drink sector is the country’s largest manufacturing industry, using around 430 million litres of water per day and ranking among the highest industrial consumers of energy. Cleaning of processing equipment is one of its most resource-intensive operations, typically accounting for 30% of both water and energy use. Current Clean-in-Place (CIP) systems often over-clean because they lack technologies capable of detecting when fouling has been fully removed, and valuable post-process water streams are frequently discharged due to insufficient monitoring.

This project will investigate the fusion of data streams from ultraviolet (UV) fluorescence imaging and in-line water quality sensors to support CIP practices. UV imaging offers a means to track fouling removal in real time and optimise cleaning performance, while in-line sensors allow post-cleaning water quality assessment and automated routing to reuse, recycling or disposal.

Combining optical fouling detection with intelligent water management is a novel approach with the potential to reduce cleaning times, save energy, and maximise water reuse. Key objectives include: (1) developing high-quality optical fouling detection; (2) determining water soil levels using existing sensors correlated with standard water quality measures; and (3) creating decision-support tools for cleaning and water management.

The doctoral researcher will have access to state-of-the-art facilities, opportunities for industrial collaboration, and comprehensive research training. Candidates should hold a strong background in engineering, applied physics, or related fields.

Primary supervisor: Dr Elliot Woolley

Secondary supervisor: Dr Patrick Webb

Entry requirements:

Students should have, or at least expect to achieve, an upper second-class honorary degree (or equivalent) at bachelor level in a relevant engineering or scientific field. A suitable post graduate degree at merit or distinction (or equivalent) would be a significant advantage.

English language requirements:

Applicants must meet the minimum English language requirements.

Funding information:

The studentship is for 3 years and provides a minimum tax-free stipend of £20,780 per annum (2025/26 rate) for the duration of the studentship plus university tuition fees.

Funding will be awarded on a competitive basis and is not guaranteed; availability will depend on the outcome of the selection process and subject to final approval by the University.
