Engineering MSc by Research at Swansea: Improving Efficiency of Wastewater Treatment

Engineering MSc by Research at Swansea Improving Efficiency of Wastewater Treatment

Port Talbot Steel Works produces large volumes of effluent which must be treated before being discharged to the Bristol Channel via the ‘Long Sea Outfall’. Effluent is closely monitored for chemical emission to water to make sure compliance with environmental permits to work . Particular compounds of interest for removal are produced via the Coke production process (carbonification) and include polyaromatic hydrocarbons (PAH), ammonia and H2S so control of the biological effluent treatment plant is critical to remaining within permitted limits.

The biological effluent treatment plant is capable of treating 1.3 million litres of effluent and uses bacteria and other microorganisms (fondly mentioned as bugs) to oxidise and breakdown the various components. Therefore, control of effluent conditions is vital to optimise the treatment. A healthy system requires a stock of healthy bacteria, along side a gentle supply of food(effluent), enough oxygen to permit oxidation to proceed, and ways of removing CO2 and therefore the excess sludge mass formed by growth and reproduction.

Project Aims:

The work aims to know biological makeup of the Biological Effluent Treatment process and to work out process drivers or solutions for improved removal efficiency, for pollutants from effluent released from the coke plant through:

1. Identify the most drivers for efficiency of the removal of pollutants, by bacteria present within the effluent treatment plant.

2. Measure ‘bug’ age and consider the way to optimise setup.

3. Identify whether it’s possible to get rid of ammonia from the effluent using the present setup.

Eligibility

• We welcome applications from candidates with a degree (minimum level 2:1) in an Engineering discipline (e.g. Chemical, Environmental, Civil) but will accept other physical sciences disciplines (e.g. Chemistry, Biochemistry), or equivalent relevant experience that might enable the candidate to fulfil the role.
• We would normally expect candidates to possess met the University’s English requirements (e.g. IELTS 6.5 overall with 5.5+ in each component) by point of application.
• Due to funding restrictions, this scholarship isn’t hospitable ‘International’ candidates.

Benefits

The scholarship covers the complete cost of UK tuition fees, plus a tax free stipend of £12,500 for a period of 1 year.
