Hazardous Waste, pH


Now a days human beings are very popular in technology & science but seem to be very helpless as for as its controlling the decay and preservative their own environmental issues. For save the environment conservation and preservation have taken on very importance in the world in recent years. Deep changes are taking place in our ways of living and working also. Among these variations resource conservation and recycling of hazardous waste have become one of the principle problems. The stabilization/solidification (S/S) technique of a hazardous (hospital) waste incineration (HWI) fly ash containing hazardous metals e.g. Pb, Cd, Cr, Zn. Different substances e.g. sodium hydroxide, potassium hydroxide, sodium silicate, potassium silicate as well as ground blast furnace slag have been used. To this end, the effects of curative conditions and composition have been tested. S/S solids are submitted to shear strength and leaching tests to evaluate the results obtained and to evaluate the efficiency of the treatment. Concentrations of the metals leached from S/S produces were strongly pH dependent, show that the leachate pH was the most vital variable for the control of metals.
