Special Process Development
Projects.
- 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.
- The use of sodium silicate
to inhibit iron precipitation from borehole waters.
- The production of sludge
flux curves in establishing correct sludge thickener
design.
- 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.
- 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.
- Evaluation of the
efficiency of both vacuum and gas strip de-aerators for
water injection facilities within the U.K. and abroad.
- The use of D.E. filters
for water injection.
- Polyelectrolytes on
filtration and clarification (high flow rate clarifiers
and filters).
- Use of polyelectrolytes in
oil removal filtration/dissolved air-flotation (produced
water and refinery effluent).
- The Operation of the
recovery of chromic acid by ion-exchange, this includes
the design, construction, commissioning and operating of
treatment plant.
- Lecture to the Institute
of Metals, London, on the novel methods of recovery of
metals by ion-exchange.
- Lecture on the control of
colloidal fouling of reverse osmosis membranes by control
of Zeta potential.
- 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.
- 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.
- The design and
construction of high throughput clarification plant.
- Sludge dewatering trials
with centrifuges of waterworks sludges to resolve sludge
disposal problems for a whole county.
