This classification normally encompasses products this kind of as house garbage, industrial wastes, mining waste, and some oilfield wastes. Liquid wastes should be less than one% solid and is generally from wastewater. Wastewater frequently includes substantial levels of dissolved salts and metals. Sludge is the ultimate regularity classification becoming somewhere involving a liquid and a solid.
