SAAFoST Cape Branch Event

Dear SAAFoST Cape Branch Member,

The response for the breakfast event on Wednesday 19 October has been very poor and it is with regret that I will have to cancel the breakfast talk.

Not to miss out of the opportunity while Oliver Hart is travelling around Cape Town, you are invited to an evening event with a presentation of his interesting research work about the use of electro coagulation (EC) and pulsed combustion (PC) in the food industry.

This is not to be missed. Please make an effort to attend.


Biography: Oliver O'Connor Hart

Oliver was born in 1947 and grew up on the East Rand, Gauteng. He studied electronic engineering at UP and Pretoria Technikon during the sixties. He is registered as a Professional Technologist Engineering - Pr. Tech. (Eng.) and is a member of ECSA.

During the seventies, he was employed by CA du Toit and Partners, consulting engineers in Pretoria, and in the mid-eighties became MD of Mitra Design Centre where he led a team of dedicated engineers to win several prestigious design awards for their achievements.

In 1995 Oliver relocated to Payson, Arizona, USA. There he designed and built a "first-of-a-kind" facility to convert biosolids into pathogen-free organo-mineral fertiliser products using pulse combustion (PC) dehydration. This pilot project received several US-EPA awards and was followed by a second similar installation in Taos, New Mexico.

In 2004, Oliver settled in Northern Ireland (UK) and founded Green Circle (EU) Ltd, focussing mainly on recovering plant and animal proteins from waste streams using (PC) drying, as well as the treatment of water based on non-biological, non-chemical electro coagulation (EC) processes.

Oliver is currently active in Spain developing new processes to dehydrate food products using PC technology. He is a specialist consultant to Neiker Tecnalia, a Government appointed technology centre serving 140 food chain co-operatives in the Basque region of Spain.

Pulse Combustion Drying
Features & Benefits

  • Direct thermal drying using dynamic atomisation instead of spray nozzles
  • Short drying cycle (300-500ms) - avoids sticky phase
  • No high pressure pumps required - < 2 bar
  • Dry pumpable slurries with high solid content - less moisture to evaporate
  • Low temperature dehydration - compete with freeze drying

Electro Coagulation
Features & Benefits

  • Electro-chemical process - Non biological, non chemical
  • Small footprint - simple to operate
  • Mineral flock - filters easy
  • Removes COD, metals, colloids, viruses
  • Ideal pre-processing for MF, UF & RO systems
