Abstract:
 
 

         An experimental study was conducted to determine the behavior of chromium compounds in the combustion environment identical to an incinerator. Experiments were conducted in a refractory lined reactor. Reactor temperature was held at 1040 deg C  +/-  20 deg C and stochiometric ratios were at 1.0 or 1.25. Experiments were conducted using sulfate, chloride and nitrate salts of  chromium with distilled and doped distilled water, “hard water”, with two different calcium and sodium concentrations. The salt solutions were injected into the post flame section of the furnace through an atomizer and the resulting aerosols were collected on a Whatman GF/C filter paper; isokinetically. These collected samples were analyzed by Powder X-ray diffraction, which were later identified by matching with the Joint Committee of Powder Diffraction Standards (JCPDS)  database of existing compounds.

 The results indicated different or same species being formed in the specific environment due to injection of different or same chromium salts. Formation of  chromium oxide (Cr(III)2O3)  was observed when chromium chloride, chromium sulfate and chromium nitrate were injected. Formation of chromatite (CaCr(VI)O4), alpha-Ca(Cr(III)O2)2, beta-Ca(Cr(III)O2)2 and Na2Cr(IV)O3 was observed when samples were made from doped distilled, “hard water”, water along with other compounds.

The Effluent Problem:

The process water which comes out of  filature plant contains high suspended and dissolved solids and also high B.O.D ( Biochemical Oxygen Demand) and C.O.D ( Chemical Oxygen Demand). Direct discharge of this effluent on land leads to a land pollution problem, and it effect ground water quality. High soluble and insoluble solid content can cause quality reduction in porosity of land which is harmful to plants and vegetable. Acid and alkaline nature of effluent has a great effect on land pollution in long run.

This is the dishroom, which payed my bills during my graduate studies at SDSM&T. $4.75 /hr, 20 hr Max/ week.
Oh well, it was tough cleaning 1300 plates each evening, but success sure has a different taste !!!
