Flight Refuelling Fluid Systems' unique crossflow ceramic membrane technology is employed in this compact, high-performance, multi-stage system designed to meet the stringent standards and controls likely to be imposed by Harbour and Maritime Authorities, especially in environmentally sensitive areas and for effluent discharges from visiting shipping. Approved to IMO 15ppm and NIAG 5ppm standards for military/civil applications, this automatic system gives effective treatment of emulsions without addition of bio agents or chemicals and a significant reduction in 'through-life' costs.
