SOIL WASHING OR FLUSHING HAS BEEN SHOWN TO BE AN EFFECTIVE METHOD FOR REMOVING HEAVY METALS FROM METAL-CONTAMINATED SOILS AT SUPERFUND SITES. SANDY SOILS CAN OFTEN BE WASHED WITH WATER TO MOBILIZE METAL IONS IN AN AQUEOUS PHASE, BUT FOR CLAY SOILS OR SOILS WHICH CONTAIN INSOLUBLE METAL COMPOUNDS, E.G., LEAD SULFATE, OTHER ADDITIVES SUCH AS CHELATING AGENTS (EDTA) ARE USED TO EFFECT TRANSFER OF MET ...

WHEN ROTATING MACHINERY DETERIORATES, VIBRTION PATTERSN CHANGE. WHEN BEARING FREQUENCIES APPEAR, THEN INCREASE IN AMPLITUDE, BEARING FAILURE LOOMS. THE SAME WITH VALVES; WHEN THEY LEAK, THEY VIBRATE. AS LEAKAGE INCREASES, THE VIBRATION PATTERN CHANGES. THERE ARE MANY OTHERS. THE KEY IS KNOWING WHERE AND HOW DEEPLY TO LOOK. THE KEY IN OLDER REACTOR PLANTS IS TO UNOBTRUSIVELY, ECONOMICALLY BACKFIT S ...

A number of industrial processes generate wastewater with mercury contamination. Existing cleanup processes have difficulties in achieving low mercury discharge limits, especially in the presence of competing metal ions already below their discharge limits. Commercial ion exchange media are not selective for mercury, so other metal ions compete with mercury for binding sites. Consequently, excess ...

THE MTIC INDIRECT STEAM REFORMING PROCESS OFFERS A COST EFFECTIVE ALTERNATIVE TO THE EXISTING WASTE-TO-ENERGY INCINERATION OF MUNICIPAL SLUDGE WASTE (MSW) OR REFUSE- DERIVED FUEL (RDF). THE PROCESS HAS THE POTENTIAL FOR RESOLVING MANY OF THE ENVIRONMENTAL ISSUES ASSOCIATED WITH INCINERATION, ESPECIALLY IN THE CONTROL OF CHLORINATED DIOXINS AND FURANS AS WELL AS EMISSIONS OF TOXIC METALS; PARTICULA ...
