A water purifying apparatus

摘要

An desalination apparatus 1 is towed behind a yacht (Y) on a high strength tube (2). An impeller (6) drives a high pressure pump (14) which draws sea water into the housing (5) where it is filtered and then pumped into a high pressure chamber (10) containing a reverse osmosis (RO) membrane (11). The pump (14) provides the energy for permeation in the RO membrane. Permeate flows into a central duct (12) and out into the tube (2) for delivery to the yacht. No yacht power plant is required and no environmental pollution is generated. <IMAGE>
