THERE IS DISCLOSED A METHOD AND APPARATUS FOR TREATING WASTE INK FROM PRINTING INDUSTRY. IN TWO POPULAR PROCESSES OF PRINTING WORK, I.E., LETTERPRESS AND OFFSET PRINTING, MUCH OF THE INK USED END UP AS WASTE. SUCH WASTE INK RESULTING FROM THE PROCESS OF PRINTING ITSELF, I.E., FROM WASHING OF PRINTING PLATES, ENGRAVED ROLLS, WIPING BLADES, TRANSFER ROLLS, AND THE LIKE; PROPER DISPOSAL OF SAID WASTE INK CREATES A SERIOUS PROBLEM TO THE INDUSTRY. EXCESS AND WASTE INK MAY CONTAIN TOXIC MATERIAL AND CANNOT BE DISPOSED FREELY FOR FEAR OF POLLUTING THE ENVIRONMENT. BECAUSE OF POSSIBLE TOXICITY TO HUMAN OR ANIMALS, DISPOSAL OF WASTE INK IS RELATIVELY EXPENSIVE AND MUST BE FRAUGHT WITH CONCERN. TYPICAL WASTE STORAGE IS NOT PRACTICAL AS SUCH METHOD REQUIRES LARGE AREA AND FEAR OF LEAKING INTO THE ENVIRONMENT IS SUBSTANTIAL. THUS, THERE EXISTS A NEED FOR AN ALTERNATIVE WASTE TREATMENT AND DISPOSAL SYSTEMS FROM PRINTING INDUSTRY THAT ARE LAWFUL, FRIENDLY TO THE ENVIRONMENT, COMPACT AND ECONOMICAL. SUCH APPARATUS FOR TREATING WASTE INK COMPRISES SLUDGE COLLECTOR TANK(L) FOR COLLECTING WASTE INK, AN INTERMEDIATE TANK(2) FOR STORING WASTE INK JUST ABOUT TO BE TREATED, A PUMP(3) FOR TRANSFERRING WASTE INK FROM SLUDGE COLLECTOR TANK(L) TO THE INTERMEDIATE TANK(2), AT LEAST ONE EVAPORATIVE SURFACE(4), HEATING MEANS FOR HEATING THE EVAPORATIVE SURFACE, AND SCRAPPER(5) FOR SCRAPPING OFF FLAKES FORMING ON THE EVAPORATIVE SURFACE. A METHOD FOR TREATING THE SAME IS ALSO DISCLOSED. (FIGURE 1)
