Full text of "Use of waste sulfate for remedial treatment of soils" See other formats. The effects of waste sulfate (phosphogypsum from fertilizer manufacture, flue gas desulfurization solids, and neutralized acid mine drainage solids) on physical and strength properties of soils have been studied. Waste sulfate alone has little effect on soil : J W Nebgen, J G Edwards, D F Weatherman.

Treatment of Sulfate-Rich Soils and Bases TxDOT 09/ Section 1 Introduction In general, the use of calcium-based additives (lime, cement, and Class CS fly ash) to treat soils and bases has been performed with success over many years. Over the past 20 years, a phenomenon has surfaced in which many subgrade soils treated with calcium-basedFile Size: 1MB.

J Cited by: Acid sulfate soil and rock What it contains This bulletin provides guidance to landowners, developers, consultants and other people involved in the disturbance of soil, sediment, rock and/or groundwater about identifying, classifying and managing acid sulfate soils and rock. Modification and Stabilization of Soils and Base for Use in Pavement Structures provides a simplified illustration of the steps required for successful subgrade treatment.

Many waste treatment technologies can pro-vide permanent, immediate, and very high remedial technologies consist of waste con-tainment approaches which require long-term operation and maintenance, In recent remedial actions, removal of wastes and con-taminants, such as soil, accounted for 40 per-cent of the cases; such removed materials.
The treatment concept leaches the gypsum contained in the CDD by water. The sulfate containing leachate is further treated and reused in the leaching step. A mixture of cheap organic materials can be utilized as electron donor for the biological sulfate reduction step, especially in gypsiferous soils treatment. Sulfate Reduction for Remediation of Gypsiferous Soils and Solid Wastes - CRC Press Book Construction and demolition debris (CDD) and gypsiferous soils contain elevated concentrations of sulfate which can cause several environmental and agricultural problems. The sulfur cycle connects with carbon, nitrogen and phosphorus cycles, thus a new platform of sulfur based biotechnologies incorporating sulfur cycle with other cycles can be developed, for the removal of sulfate and other pollutants (e.g. carbon, nitrogen, phosphorus Cited by: The project should be scheduled to minimise the time acid sulfate soil material is exposed to air. This. involves scheduling the works so acid sulfate soil can be reburied as quickly as possible (that is within. the same working day) and to minimise the exposure time of soils .
