Licensed Technologies

The following licensed technologies are being used.

Capillary ultra-filtration membrane technology (CUF), a cluster of 5 patents

The capillary ultra-filtration membrane technology is exclusively licensed to a BEE company, Ikusasa Chemicals (Pty) Ltd. The membranes and systems are now being manufactured locally by Ikusasa water management (IWM) , a subsidiary of Ikusasa Chemicals Pty Ltd. IWM is a visionary company providing cutting edge membrane and water management technologies through its modern producing facilities, highly qualified and experienced personnel.

The capillary ultra-filtration membrane technology has many advantages over conventional water treatment:

• The product water is of higher quality
  
• The process is easy to automate and less operator intervention is required
  
• A physical barrier against pathogens, including parasites and chlorine resistant species, is offered
  
• Quality of product water is less sensitive to feed water quality variations
  
• Systems design allows easy, modular construction
  
• The system can operate easily at lower flow rates during off-peak demand
  

Secondary metabolites, a cluster of 13 patents licensed to Synexa-Life Science Pty Ltd

The Quorus Bioreactor range of disposable bioreactors is a significant innovation in bioprocessing; offering a highly productive, easily-scalable and fully automated range of bioreactors, from lab scale to production scale.

At the heart of the Quorus Bioreactor is a series of ceramic membranes that allow micro-organisms and cell cultures to grow as biofilms in a very low-shear and controlled mass-transfer environment. The result is high-quality, cell-free product produced in a highly-efficient continuous process that makes DSP much simpler than in alternative bioprocessing systems.

The key features of this technology include:

• A novel and patented membrane-based process
  
• Enhanced volumetric productivity
  
• A stable, continuous process
  
• Linear scale-up from lab to production scale
  
• High mass-transfer efficiency and low shear
  
• Available in microbials and cell culture versions.
  

The BioSURE™ process, a cluster of 36 patents, is licensed to ERWAT

The BioSURE technology is exclusively licensed to East Rand Water Care Company (ERWAT). ERWAT offers a world-class, yet economic solution to water and wastewater management through its ground- breaking advanced technologies.

The BioSURE technology is a cost effective biological treatment option for reducing sulphate in acid mine water without the external addition of chemicals. The BioSURE process removes acid from acid rich mine water.
