Special Process Development Projects.

  1. The determination of corrosion rates of differing treated waters at different temperatures and the effectiveness of final water pH control and corrosion treatment with sodium hexametaphosphate and sodium silicate.
  2. The use of sodium silicate to inhibit iron precipitation from borehole waters.
  3. The production of sludge flux curves in establishing correct sludge thickener design.
  4. Pre-treatment for reverse osmosis - novel methods in the control of colloid/particle removal with filtration and polyelectrolytes, both at pilot plant scale and on full size plant.
  5. Sea-water filtration for water injection. Investigations in the up-rating of sand filters, reduction of coagulant feed rates and the use of polyelectrolytes to improve particle removal.
  6. Evaluation of the efficiency of both vacuum and gas strip de-aerators for water injection facilities within the U.K. and abroad.
  7. The use of D.E. filters for water injection.
  8. Polyelectrolytes on filtration and clarification (high flow rate clarifiers and filters).
  9. Use of polyelectrolytes in oil removal filtration/dissolved air-flotation (produced water and refinery effluent).
  10. The Operation of the recovery of chromic acid by ion-exchange, this includes the design, construction, commissioning and operating of treatment plant.
  11. Lecture to the Institute of Metals, London, on the novel methods of recovery of metals by ion-exchange.
  12. Lecture on the control of colloidal fouling of reverse osmosis membranes by control of Zeta potential.
  13. Technical manuals on various treatment processes, these include the commissioning of high rise rate clarifiers for engineers, filtration theory and design and the commissioning of filter plants.
  14. Operating manuals which include clarification, filtration plant, anaerobic digestion, reverse osmosis operating and chemical cleaning procedures , effluent treatment plant as well as chlorination and treatment of private water supplies.
  15. The design and construction of high throughput clarification plant.
  16. Sludge dewatering trials with centrifuges of waterworks sludges to resolve sludge disposal problems for a whole county.
