Abstract
A process for recovering potable water from the exhaust gases of an internal combustion engine is disclosed. In this process the exhaust gases are cooled causing water to condense out, and the water formed is passed through particulate filters, activated carbon filters and ion exchange resin filters. In this process, the water is treated to reduce the levels of nitrates, sulfates, acidic and other organic components therein (for example, by passing it through a flow through capacitor) before the water is passed through the ion exchange resins. The apparatus for practicing this process is also disclosed.
Claims12
In a method for recovering potable water from the exhaust gases from an internal combustion engine, comprising the steps of:
- (a) cooling said exhaust gases so as to cause water to condense from said exhaust gases;
- followed by
- (b) passing said water through one or more particulate filters having a maximum pore size of from about 0.1 to about 10 microns;
- (c) passing said water through one or more activated carbon filter beds;
- and
- (d) passing said water through one or more ion exchange resin filter beds;
- the improvement which comprises, prior to step (d), treating said water so as to reduce the levels of nitrates, sulfates, acidic and other organic components therein.
A method for recovering potable water from the exhaust gases from an internal combustion engine, comprising the steps of:
- (a) cooling said exhaust gases so as to cause water to condense from said exhaust gases;
- followed by the following steps carried out in any order:
- (b) passing said water through one or more particulate filters having a maximum pore size of from about 0.1 to about 10 microns;
- (c) passing said water through a treatment to oxidize/remove organics, selected from a flow through capacitor, an electrochemical cell, reverse osmosis, and combinations thereof;
- (d) passing said water through one or more activated carbon filter beds;
- and
- (e) passing said water through one or more ion exchange resin filter beds;
- provided step (c) is carried out prior to step (e).
In an apparatus for recovering the exhaust gases of an internal combustion engine comprising a means for connecting said apparatus to the exhaust portal of said engine;
- a means for cooling the exhaust gases so as to cause the water in said gases to condense;
- a means for collecting said water and channeling it to a purification system which comprises one or more particulate filters having an average pore size of from about 0.1 to about 10 microns, one or more activated carbon filter beds, and one or more ion exchange resin beds;
- and means for collecting the water which has passed through said purification system;
- the improvement which comprises the inclusion in said purification system of a means for reducing the level of nitrates, sulfates, acidic and other organic components in said water prior to passing said water through said one or more ion exchange resin beds.
