About

I am a technical innovator in the area of biological processes, with expertise in microbiology and experience of biochemical engineering. Three of my innovations related to improvements to expanded bed biofilm reactor (EBBR) technology have been granted patent status. This technology can be used for treatment or raw, used or waste water, fermentation or biocatalysis.

After extensive pilot plant trials treating activated sludge settled effluent at the United Utilities Davyhulme plant in Manchester (UK), the EBBR was shown to have the lowest cost of ownership and reduce an average inlet ammonia concentration of 21 mg/L to 0.4 mg/L. The process was also found to remove >50% of residual organic matter (BOD), most likely through ​the activity of ​heterotrophic ​bacteria; >60% ​TSS and >85% ​bacteria, most ​likely through ​the activities ​of protozoa and ​rotifers; and ​40-60% of the ​synthetic ​oestrogen, ​ethinyl ​oestradiol (EE2)​, most likely ​through ​hydroxylation ​by ammonia mono-​oxygenase. 

The process ​is not yet ​commercially ​available but ​we have ​developed it to ​Technology ​Readiness Level ​7 (prototype ​package plant, see photo). ​Nevertheless, ​if you would ​like further ​information, ​please contact ​me.
