Staff Profile

Dr Paul Sallis

Senior Lecturer in Environmental Engineering



Joined Civil Engineering within the School of Engineering in 1997 as a Lecturer in Environmental Engineering specialising in biological treatment processes in wastewater treatment, focusing on the degradation of recalcitrant contaminants in industrial wastewaters by aerobic and anaerobic treatment systems. Recent focus has been on the conversion of biological waste to renewable energy by anaerobic systems.

Currently a Senior Lecturer in Environmental Engineering.

Industrial Experience

Worked for 4 years as Project Development Manager, IBS Viridian Ltd, Whitstable, Kent.

Effluent Treatment - Process design for liquid effluent treatment systems; preparing proposals and tender documents; management of laboratory and technical treatability programmes; responsible for pilot plant demonstration trials.

New Business Development - evaluation of business and product development opportunities; Patent application and registration; resource and project management from initial concept designs through to finished product; coordination of manufacture, fabrication, installation, commissioning, and system performance.  Specifying service and maintenance protocols for new equipment.

Scientific R&D Programmes -  Management of collaborative industrial research and development ventures with academic partners to exploit and commercialise leading-edge technologies for soil bioremediation and liquid effluent treatment. Securing IPR protection.

Worked for 3 years as Project Team Leader, International Institute of Biotechnology, Kent.

Headed a team of five multi-disciplinary scientists and engineers working on a three year programme for Hercules Chemical Corporation developing a novel bioprocessing technology to remove organohalogen pollutants from wet-strength resins used in commercial paper manufacture. Managed all stages of process development from initial identification, selection and evaluation of potential bacterial biocatalysts, to the design and implementation of a patented industrial bioprocess now used in the production of modern environmentally improved wet-strength resins.


Research Interests

Theme  - Anaerobic Digestion and Sustainable Energy

  1. Anaerobic digestion of industrial wastewaters (pharmaceutical) with  Eli Lilley
  2. Anaerobic digestion of municipal solid waste organic residues (North Tyneside Council)
  3. Use of macroalgae (seaweed) as large-scale biomass feedstocks in  sustainable biogas production (ITI Energy)
  4. Biogas generation from microalgae – effect of AD reactor design and operation on Biogas yield (EPSRC).
  5. Biogas generation from microalgal feedstocks in membrane anaerobic bioreactors.


 Theme - Water treatment in developing countries

1. Development of sustainable production methods for simple ceramic water filters 

2. Development of hand-pumped membrane water filters (with The Safe Water Trust).

3. Development of simple solar stills for fluoride and arsenic removal.

4. Development of solar tracked Fresnel lens for thermal disinfection of raw water


Postgraduate Supervision

Has mentored over 10 successful doctoral  theses and has supervised over 50 M.Sc. Dissertations. Currently  supervises  three  PhD  students,  two  being  overseas  students,  and  one  Postdoctoral Associate through funding from the Jordanian, Malaysian and Kuwait Governments and the UK EPSRC.
