Liquid photopurification specialist company SurePure Inc. apprises of a breakthrough in the microbiological purification of contaminated marine diesel fuel, using SurePure's technology as an alternative to biocide addition or excessive micro-filtration. SurePure explains that the contamination of diesel fuel is a significant problem for the maritime shipping industry, leading to extensive waste of fuel and environmental contamination. The industry is seeking to improve conventional means by which it cleans fuel where micro-organisms have proliferated. SurePure, in conjunction with a South African oil industry consultant Lemon Tree Holdings, applied its proprietary Turbulator technology in a test conducted in April at Stellenbosch, South Africa.
