THE PROPOSAL RESPONDS TO THE INCREASING PRESSURE TO RECYCLE PAPER. SINCE NONBLEACHED PAPER USES ALMOST 100% RECYCLE PULP, ADDITIONAL RECYCLING MUST COME FROM BLEACHING RECYCLEDPULP TO BE SUITABLE FOR NEWSPRINT AND WHITE PAPER. THE OBJECTIVE OF THE EXPERIMENTS IS TO DEMONSTRATE THE FEASIBILITY OF BLEACHING RECYCLED PULP WITH A UNIQUE CHEMICAL MIXTURE. THE EXPERIMENTS WILL USE SAMPLES OF COMMERCIAL ...

NEW IDEAS ARE PRESENTED ON THE COVALENT ATTACHMENT OF CHELATING FUNCTIONALITIES TO A COMMON, INEXPENSIVE SORBENT MATERIAL, WHICH CAN THEN COMPLEX HEAVY METAL IONS IRREVERSIBLY. THE EFFICIENT REMOVAL OF LEAD, CADMIUM, CHROMIUM, MERCURY, ZINC, NICKEL, COBALT, IRON, AND COPPER ISANTICIPATED. THE COVALENTLY ATTACHED LIGANDS ARE EXPECTED TO BE STABLE TOWARDS HYDROLYSIS AND PH VARIATIONS. THE CAPACITY O ...

A NOVEL PROCESS AND FORMULATION ARE PROPOSED FOR PRETREATMENT OF PLASTIC SURFACES. THE FORMULATIONS ARE INEXPENSIVE NONTOXIC AND NONPOLLUTING. WHEN PLASTIC PARTS ARE IMMERSED IN THE FORMULATIONS, THE SURFACES OF PLASTICS WILL BECOME RECEPTIVE TO WATERBORNE PAINTS. THE ADHESION OFWATERBORNE PAINTS IS EXPECTED TO BE BETTER THAN THAT OBTAINED WITH SOLVENTBORNE PAINTS. MILLIONS OF GALLONS OF SOLVENTBO ...

A NEW METHOD FOR REMOVING ACID RAIN PRECURSORS FROM COAL-FIRED BOILERS HAS BEEN CONCEIVED. THE CONCEPT INVOLVESA TAIL-END SCRUBBER RETROFIT FOR INSTALLATION IN PLANTS WHICH PRE-DATE THE 1970 CLEAN AIR ACT. THE CONCEPT IS HIGHLY INNOVATIVE AND HAS MANY ADVANTAGES OVER OTHER SORBENTINJECTION PROCESSES. HETEROGENEOUS REACTIONS BETWEEN SO2 AND CALCIUM-BASED SORBENTS ARE AFFECTED BY THE MASS TRANSFER B ...

CARBON ADSORPTION IS A WIDELY USED TECHNIQUE TO REMOVE AND CONCENTRATE VOCS FROM DILUTED AIR AND WATER STREAMS. PERIODICALLY CARBON BEDS ARE REGENERATED WITH STEAM. THE RESULTS OF THIS REGENERATION AFTER COOLING, IS A CONCENTRATED MIXTURE OF HAZARDOUS COMPOUNDS AND WATER. COMMON AND PARTICULARLY TROUBLESOME STREAM CONDENSATES ARE THOSE CONTAINING MIXTURES OF CHLORINATED SOLVENTS AND WATER-MISCIBLE ...

CFCS EMITTED AS PURGE STREAMS FORM LARGE INDUSTRIAL REFRIGERATORS ARE A CONSIDERABLE ENVIRONMENTAL PROBLEM AND AN ECONOMIC LOSS. MEMBRANE ORGANIC VAPOR RECOVERY SYSTEMS APPEAR TO BE ABLE TO TREAT THESE STREAMS. A MEMBRANE UNIT COULD RECOVER CFC FOR REUSE IN THE REFRIGERATOR, AND PRODUCEA CFC-DEPLETED AIRSTREAM FOR VENTING. IN THE PHASE I PROGRAM, EXISTING MEMBRANES WOULD BE FABRICATED INTO HIGH-PR ...
