Abstract: A masonry product is formed from a composition comprising a blend of fly ash and kiln dust. A process for forming the product comprises mixing fly ash, kiln dust, and water; and applying a pressure.

Abstract: Mineral Lime is a composition having from about 85% to about 95% by volume of fly ash and from about 5% to about 15% by volume of kiln dust. A composition for Mineral Lime can also have from about 85% to about 95% by volume of Class C fly ash; and from about 5% to about 15% by volume of lime kiln dust. A process for producing a composition of Mineral Lime including fly ash and kiln dust, includes the steps of feeding fly ash to a blender; feeding kiln dust to the blender; and blending the fly ash and kiln dust in the blender.

Abstract: The invention provides an improved, cost-effective means of transforming sludge or ther waste from vertebrates into fertilizer comprising the steps of 1) mixing a composition containing calcium oxide (CaO) and magnesium oxide (MgO) with sludge or other waste products from vertebrates, 2) allowing the mixture to reach a temperature of about 70° C., then 3) allowing the mixture to remain at a minimum temperature of about 70° C. for a minimum 30 minutes. At the end of this time, most of the material is sufficiently dewatered and can then be bagged to be sold as an organic fertilizer.

Abstract: A fluid mixing device comprises a housing provided with fluid entry ports for fluids being treated, and for treatment fluids, as well as a fluid discharge port for the discharge of treated fluids. A compound valve arrangement is positioned in the entry port, comprising one valve for adjusting the amount of treatment fluids entering the mixing device, and in series therewith a toggle valve actuated by a rod attached to the toggle valve which extends into the housing and which is actuated by the impact of fluids passing through the device. The mixing device is particularly suited to the neutralization of mine waste waters with caustic soda and for the introduction of polymer flocculents to induce the settling of solids in liquid suspension.
