Waste water treatment system

A water treatment system suitable for utilization in mobile platform technologies to remove TNT, and potentially other toxicants, and particulate matter from waste stream water, comprising the sequential connection of sub-stations in the following order:

• at least one sand filter sub-station, with said sub-station additionally featuring, a filter sheet positioned under a waste stream feed pipe opening, concentrically draped along a similarly-shaped sand bed, configured such that the gap separating the sheet and the pipe opening is the waste stream drop height, h, and configured such that said sheet is slightly undersized so as to cover 92-97% of the sand bed;
• said filter sheet is further configured such that the fraction of the sheet draped along a centralmost region of the sand bed serves as the site to feed a waste stream and to support the deposition and growth of a filter cake displaying a hill-like cross-section, and configured such that the fraction of the sheet draped along a ring region and a periphery region of the bed permits through-sheet transfer of the stream to the underlying periphery region and lateral transfer to the undraped perimeter region of the bed;
• wherein a vacuum pump is configured to speed the flow of the stream through all filtration media and to discharge a filtrate at the sand filter base, the effect of the above features and configurations being to extend filtration times and operating capacity, maximize cake growth, reduce maintenance down times, and raise the efficiency and utility of the filtration rounds;
• at least one ultrafiltration sub-station;
• at least one nanofiltration sub-station;
• and
• at least one active granular carbon purification sub-station.
