SupaZorb offers solutions to hydrocarbon spills, the detection of underground precipitation of a spill and UXO.

Our Technology won several international innovation awards. More information is available on here.
The SupaZorb Company and Technology were founded in 1995 based on sound scientific research. It was developed in collaboration with the S.A. Department of Geo-Sciences, University of Pretoria, North-west University, University of Zululand and many more. The technology started with the development of an organic absorbent, made from plant detritus containing specific micro organisms to metabolize hydrocarbons and plastics. The metabolic pathway guarantees a result of less toxicity and SupaZorb prides itself on the results achieved, where 70% of diesel spills were metabolized to Diethylcyclobutane (known as a medication used as an Anti-Parkinson's drug and Anti-Psychotics, only to mention a few).
A need arose to develop a new technology in the facade of Geophysical Instrumentation in order to instantly and none destructively determine the spill (plume) and the direction of migration as well as the possible risks of water table contamination. The same instrument was required to be proficient to measure the success after remediation or to indicate the progress of the remediation. The most recent technologies and combinations of technologies, available, were tested and well researched. The Magnetic Conductivity/Resistivity, with its magnetic susceptibility, proved to be the most effective geophysical instrument. Many software programs were tested, but the Surfer Program was the only software that could instantly convert the data to a color illustration, while indicating the apparent conductivity and apparent resistivity values. All matter has certain conductivity and resistivity values and can immediately be identified on the surfer printouts. Surfer illustrates in 3D format, the area - sliced and in layers, indicating exact GPS coordinates and depth.
Most of the geophysical surveys done, identify scrap metal or steel reinforcing. Metal wire (fencing) of 3mm was also identified. Accuracy to date: 50 – 100mm and particular conductivity of approximately 580 - 640mSm indicates steel; cast-iron and stainless steel. Further tests at suspended height of 3m (from ground level) illustrated a slight noise on the apparent resistivity, but none on the conductivity. These tests were performed at a controlled speed of 9km/h and 6m in width. This device was highly effective up to 6m in depth and 11m - at certain times.
A superior version of this device consists of two larger coils (magnetic dipoles). It can penetrate 60m and can cover 40m in width. However, it must be stated that in some geological phenomena, data could be obscured for interpretation, the deeper you penetrate.

It is important to mention that historical lessons in regards to UXO, revealed that reliance should not be placed on merely one technology. It is recommended that different technologies should be combined as a back-up plan. We prefer to use 4 different technologies before conclusions are made.
