    Abstract: A manufactured granular substrate composition suitable for use as a carrier for active chemical agents. The composition includes one or more mineral components having a bulk density greater than about 70 pounds per cubic foot. The composition also contains about one or more light weight additives and one or more water soluble binders. The resulting manufactured granular substrate has a bulk density of less than about 55 pounds per cubic foot with a size guide number of about 75 to about 300.

    Abstract: A dephosphorizing material containing iron and/or an iron-containing compound, a cementitious material, water, and a mixing agent for accelerating bleeding as the starting material, and having fine pores therein formed by solidifying the starting materials while bleeding not less than 2.0% by weight of the water contained in the starting materials to render the percent water absorption of not less than 10%; and a dephosphorizing method which includes bringing the dephosphorizing material into contact with a phosphorus-containing aqueous solution. This dephosphorizing material can effectively reduce the phosphorus concentration in sewages, rivers, or the like by fixing the phosphorus component on its surface. The dephosphorizing method is so simple that it can be effected merely by bringing the dephosphorizing material into contact with a phosphorus-containing aqueous solution, thus being capable of removing the phosphorus component effectively without necessity for any special controls.
