متن کاملLime and Distilled Water Treatment of Dispersive Soils by Electroosmosis Effect (TECHNICAL NOTE)
This paper explains the procedure and results of electro osmosis treatment of a dispersive soil. A number of cylindrical specimens of a dispersive soil were subjected to the electro osmosis effect and the subsequent cation changes in the soil, inlet water and outlet water were measured. The tests were carried out using distilled water and lime extract in anode. It was observed that with distill...
متن کاملReuse of water treatment residuals from lime softening, Part I: Applications for the reuse of lime sludge from water softening
Lime sludge, an inert material mostly composed of calcium carbonate, is the result of softening hard water before distribution as drinking water. A large city such as Des Moines, Iowa, produces about 32 000 tons of lime sludge (dry-weight basis) annually. This is about half of the lime sludge produced in Iowa per year in eight different cities, and these cities currently have 371 800 tons (dry-...
