Transportable reverse osmosis water purification unit

A self-contained, transportable reverse osmosis water purification unit having a throughput of no more than about 20 gpm of permeate in a single pass operation, said unit comprising,

• an enclosed weather-tight housing having a continuous base integrally combined with said housing to form a purification container having the overall dimensions of an ISO container, said purification container 5.5 m long.times.2.1 m wide.times.1.7 m high being adapted to be demountably disposed in a transport means from which said purification container may be deployed without due care, to land on the ground in a horizontal position, right-side-up;
• an A-frame integrally combined with said base, each including attachment means for deploying said container;
• hydrocarbon fuel-powered generating means for generating sufficient electricity at a voltage required to operate all components powered by electricity, and storage means for storing enough fuel to operate said generating means for a predetermined period of time;
• said housing being divided into first and second enclosed compartments separated from one another by a dividing wall, said second compartment having said fuel storage means, and said generating means including electrical control means therefor and a storage battery, housed in said second compartment;
• said first compartment having housed therein substantially all remaining components for purifying raw contaminated water, said components including, a first pass reverse osmosis module and a second pass reverse osmosis module;
• a feed pump, a booster pump, first pass and second pass process pumps, and a chlorine injection pump;
• first pass and second pass reverse osmosis modules having reverse osmosis elements disposed therein;
• coarse filter means and fine filter means;
• a bladder tank having a capacity of at least 17 gal;
• a cleaning tank having a capacity of at least 30 gal;
• and, control means to operate said components to deliver no more than 20 gpm of permeate in a single pass operation;
• said first and second compartments having equipment therein demountably secured to said base and interior surfaces of said compartments with shock-absorbing means, said equipment being essentially symmetrically distributed about the center of mass of said container,
• whereby said container may be unloaded from a supporting surface above the ground and land thereon, base first, and remain oriented in a substantially vertical position.
