Treatment and Disposal of Gypsum Board Waste -- Industry Position Paper
Background Gypsum, or calcium sulfate dihydrate, (CaSO4 l 2H2O) is the major component of drywall, or gypsum board, core. It is a naturally occurring mineral, deposited largely as a result of the evaporation of water in ancient inland seas, which contained large amounts of dissolved gypsum. For example, the evaporation of a typical 20,000 gallon residential swimming pool filled with seawater wi...

متن کاملDevelopment of Inexpensive Adsorbent from Agro-Waste for Phenol Adsorption
Potential adsorption of phenolsmajor pollutants present in various industrial wastewaters onto adsorbent powdered activated mustard cake (PAMC) derived from (mustard cake MC) agriculture waste materials was evaluated. The PAMC had meso porous pore size distribution with surface area (27 m g). The adsorption characteristics of the PAMC primarily attributed to the presence of silica or mixed oxid...
متن کاملAdsorption of Heavy Metal (Cu, Ni and Zn) from Synthetic Waste Water by Tea Waste Adsorbent
Industrial waste constitutes the major source of various kinds of metal pollution in natural water. There are at least 20 metals which cannot be degraded or destroyed. The important toxic metals are Cu, Ni and Zn. There are numerous methods currently employed to remove and recover the metals from our environment and many physicochemical methods have been proposed for their removal from wastewat...
